Answer:
Due to some extra features.
Explanation:
Genetic materials from two parent plants of the same species has many advantages because the offspring produced from two parents having characteristics from both parents which make it different from their parents. Due to this non-identical nature of offspring which has many new features which enables the plant to resist many diseases, faster growth and high productivity so that's why sexual reproduction has many benefits to organism.
In one study, 108 regions of the genome were identified to be significantly associated with schizophrenia. Below is a Manhattan plot showing the results from this study. Assuming that none of the causative variants are linked and there is a single causative variant per peak region, how many regions of chromosome 6 with causative variants were identified in this study
Answer: hello your question is incomplete attached below is the missing part of the complete question
The top of the highest peak corresponds to a region of the genome called the MHC locus. This means that of all the variants identified by this study, ____________.
the variant in MHC is observed the most frequently in the affected cohort.
the variant in MHC can cause schizophrenia in a Mendelian fashion.
the variant in MHC is the least likely to be a false positive result.
the variant in MHC has the largest odds ratio.
answer:
i) 4
ii) the variant in MHC is the least likely to be a false positive result. ( C )
Explanation:
The number of regions of chromosome 6 with causative variants identified is 4
While the variant in MHC is the least likely to be a false positive result. this is because, it is the highest peak in of all the causative variants identified in this study (i.e. closely related to the disease) and been the highest peak will make it least likely to return a false positive result.
What’s the main reason why cell specialization is important
Explanation:
because we know that cell makes up organ and organ makes organ system and this system makes organism....cell is also the structural and functional unit of life it there were no cell specialization then mitosis and meosis wont take place neither cell division
Which of the following events is typical of meiosis but not of mitosis?
A the chromosomes are highlighted
B. the centrioles are formed
C chromatids separate
D. the homologous chromosomes are paired AND the spindle is formed
Answer:
D. the homologous chromosomes are paired AND the spindle is formed
Explanation:
Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.
In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.

Genes a and b are 10 map units apart, b and c are 20 map units apart, and a and c are 30 map units apart. If a triple heterozygote is testcrossed, among 1,000 progeny, how many are expected to result from double crossovers if there is no interference?
а. 10;
b. 20;
c. can't be determined
d. 30;
e. 60;
Answer:
20 ( B )
Explanation:
Given data:
a and b are 10 map units apart
b and c are 20 map units apart
a and c = 30 map units apart
condition ; Triple heterozygote testcrossed
number of progeny = 1000
Determine the number of double crossover result
P( crossover between a and b ) = 10/100 = 0.1
P( crossover between b and c ) = 20/100 = 0.2
p( double crossover ) = 0.1 * 0.2 = 0.02
hence number of double crossovers = number of progeny * 0.02
= 1000 * 0.02 = 20
Classify each item as being associated with light positioning (controlling how and where light strikes the retina) or sensory processing (how that information is processed).
a. Photoreceptors
b. Occipital cortex
c. Extrinsic muscles
d. Pupil
e. Bipolar cells
Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.

The genetic code is defined degenerate or even redundant because:
A. the same codon codes for different amino acids
B. an amino acid can be encoded by several codons
C is different in all organisms, except in monozygotic twins
D. the sequence of codons is not separated by intervals, but is continuous
E. the structure of the genes is constantly mutating
Answer:
B. an amino acid can be encoded by several codons
Explanation:
The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.
Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.
For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

For the following three cultures, using any resource find out if they are obligate aerobes, facultative anaerobe, or obligate anaerobe- o Escherichia coli o Micrococcus luteus o Clostridium sporogenes
Answer:
Escherichia coli - Facultative anaerobe
Micrococcus luteus - Obligate aerobe
Clostridium sporogenes - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are Mycobacterium tuberculosis and Micrococcus luteus.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the Escherichia coli.
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are Clostridium sporogenes and Clostridium botulinum.

If a less concentrated initial solution of sodium bicarbonate was used in beaker C, would that solution require more or less bicarbonate to neutralize the acid? Why?
Less bicarbonate would be required to neutralize the acid if a less concentrated initial solution of sodium bicarbonate was used in beaker C.
What is bicarbonate?Bicarbonate is a naturally occurring chemical compound composed of sodium, hydrogen and carbonate ions. It is a salt and a weak acid, and its chemical formula is NaHCO3. Bicarbonate has many uses, including baking, cleaning, medicine, and neutralizing acids. Baking soda, which is sodium bicarbonate, is used in baking as a leavening agent. It acts to create air bubbles in dough, which helps breads and cakes to rise. Bicarbonate is also used in cleaning products as a mild abrasive and a pH buffer.
This is because a less concentrated solution will have fewer moles of bicarbonate per liter of solution, thus requiring less bicarbonate to neutralize the same amount of acid.

Discuss how important you think it is to protect ecosystems from human-induced change, such as changes in habitat or introduction of invasive species. Should natural conditions be preserved at all costs, should human needs always prevail, or is the answer somewhere in between? Discuss the negative consequences of taking an approach that you disagree with.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits.
Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air. Protecting wildlife and preserving it for future generations also means that the animals we love don't become a distant memory. And we can maintain a healthy and functional ecosystem.
A reproductive cell must differ from other normal body cells. The reproductive cell must ______________ because it will soon fuse with another reproductive cell to form a new individual
I'm not 100% sure what the exact answer is to this, because lots of things could be said about what gametes need to do for reproduction.
I suppose since it says that it's combining with another cell, it's hinting at the fact that reproductive cells are haploid.
If this is multiple choice I would choose the choice that has to do with gametes being haploid.
A reproductive cell must differ from other normal body. The reproductive cell must Haploid because it will soon fuse with another reproductive cell to form a new individual.
How is a reproductive cell specialized?The requires the union of two specialized cells, called gametes, each of which contains one set of chromosomes.

Write the events of the human life cycle in the correct order, starting with what happens right after a pair of gametes comes together?
Answer: Fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, meiosis produces sex cells that will participate in fertilization.
Explanation:
Incomplete questions, options are:
Meiotic cell division occurs as the zygote develops into a gamete, meiosis produce the sex cells that will participate in fertilization, a baby grows into an adult through uncountable meiotic divisions, fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, mitosis produces gametes.
1. Fertilization occurs: Fertilization is the union of a human egg and sperm (male and female gametes), which usually occurs in the fallopian tube. The result is the formation of a zygote or fertilized egg, which initiates the development of the embryo. In this way, the genetic material of both gametes is also fused.
2. A zygote undergoes mitosis: The zygote is the union of the egg and the sperm. Each gamete contributes 23 chromosomes to form the genetic material of the future organism. The zygote starts to divide throught mitosis. Mitosis is a type of cell division that generates two genetically identical daughter cells and occurs in somatic cells (all cells in the body that are not gametes). Eventually, it divides into two blastomeres, then into 4, then into 8, and so on during the passage of the zygote along the fallopian tube towards the uterus. Subsequent divisions of the 12 cells give rise to the morula. Then, the blastocyst is generated, which is an embryo of between 5-7 days of development and is composed of a large number of cells that begin to differentiate.
3. A baby's cells divide mitotically: An embryo is a living being in the early stages of its development, from fertilization until the organism acquires the morphological characteristics of the species. In the specific case of the human being, the term applies until the eighth week after conception (fertilization). Cell divisions for development occur by mitosis. In this way, the embryo will grow and develop, forming tissues and organs through growth thanks to mitotic divisions.
4. Meiosis produces sex cells that will participate in fertilization: Meiosis is a type of cell division that occurs in the gonads for the production of gametes, whereby a diploid cell undergoes two cell divisions, that generates four haploid cells. Thus sperm and oocytes are produced to eventually fuse during reproduction to form a diploid zygote. Meiosis has certain differences from mitosis, since in this type of cell division, the daughter cells created are all genetically distinct from each other and from the parent cell. This is because a crossing over occurs between non-sister chromatids of homologous chromosomes to exchange genetic material. This ensures that each gamete produced has genetic variability.

what are the biological structures
Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.
Explanation:
Answer:
Structural biology is a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules (especially proteins, made up of amino acids, RNA or DNA, made up of nucleotides, and membranes, made up of lipids), how they acquire the structures they have, and how alterations in their structures affect their function.

What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae
Answer:
RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.
