Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.
In pea plants, round seed shape (R) is dominant over wrinkled (r). Write the genotype for a plant that is heterozygous.
Answer:
Rr, heterozygous traits have one recessive and one dominant, therefor meaning its going to be Rr
Answer:
R.r
Explanation:
Hetero = different
Hom0 = same
An individual hom0zygous for a particular trait has two of the same allele at the gene. In this case, it would either be R.R or r.r.
An individual heterozygous for a particular trait has two different alleles, in this case it is R.r.

CELLS: Choose three membrane-bound organelles. Describe them below.
Include their shape, location, and a detailed description of their function.
Answer:Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Explanation:
Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a golgi apparatus that packages and distributes proteins. Mitochondria are the power house of the cell and provide the cell with energy.

II. Write a position statement on whether you think athletes like Santhi should be allowed to compete. Use evidence based reasoning in your position.
Answer:
The correct answer is stated in the Explanation section.
Explanation:
Santhi Soundarajan is an Indian track and field athlete that have won multiple international medals. Santhi was the center of a controversy when she was striped her silver medal after failing a sex verification test at the 2006 Asian Games. Santhi has a condition known as androgen insensitivity syndrome, she carries a Y chromosome althoug she has female genitalia. I think is not fair to disqualify an athlete like Santhi unless it is determined that she committed fraud and that she has an evident advantage. If Santhi knew her condition and it is established that she has an advantage after multiple tests, then her medal could be removed.

Explain the relationship between the length of a Great White
Shark and how much food it eats per year.
Answer:
Explanation:
Every living thing grows. It needs energy to grow. It gets energy through food. When it doesn't have enough energy, it won't grow as fast. When it does, it will grow normally. If it get's more than enough, it will grow faster. One exception is if that organism is a human, and is having a growth spurt.
Which of the following factors is most likely to decrease the stability of an ecosystem?
A
The removal of a species
B
An increase in plant biodiversity
C
The removal of an individual animal
D
An increase in animal biodiversity
Answer:
A
Explanation:
The removal of a species can reduce the food source of another species, which can cause that species to slowly die out, where other animals that consume the dying species start dying out... ect.
So it decreases the biodiversity which can mess with populations.
If the species is a herbivore, it could cause the plants that are eaten by that herbivore to get out of control in population, which can fight for sunlight and resources with other species causing ecosystem collapse.
In an ecosystem, the removal of a species can decrease the stability. Thus, option A is correct.
What are the biotic factors of an ecosystem ?Biotic factors are the basic unit of ecosystem where the living beings interact with each other and their environment.
There are two components of an ecosystem such as biotic and abiotic components, include distribution of energy in our environment.
Biotic components can be classified into autotrophs, heterotrophs and decomposers based on mode of nutrition.
Autotrophs are producer such as plants as they produce food through the process of photosynthesis.
Heterotrophs are the consumer depend on producer for their nutrient, which is further classified into three categories.
Primary consumers are herbivores rely on producers for food while secondary consumers depend on primary consumers. They can be carnivores or omnivores.
Tertiary consumers depend on secondary consumers for food. some quaternary consumers are also seen in some food chains.
Decomposers include saprophytes such as fungi and bacteria which lie on decaying organic matter and essential for the ecosystem
Hence, option A is correct.

Regular physical exercise is a great way to improve your overall well being. Exercise controls weight, improves mood, boosts your energy and metabolism, improves sex life and promotes good sleep. The physical activity is usually accompanied by increase in body temperature and sweating. What is the reason for the increase in the body temperature? Explain the relationship between sweating and body temperature and the significance of this feedback. What type of feedback system? identify all components of the feedback system.
Answer:
Explanation:
"A part of your brain called the hypothalamus controls your body temperature. In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature. So when a fever comes on, it's a sign that something is going on in your body."
In a population of frogs, there is a dominant allele H that improves the survival of eggs in moderately dry conditions compared to the wild-type and recessive h allele. Imagine that climate change causes the environment where these frogs live to become more dry. Individuals with the drought-resistant eggs on average have 21 viable offspring per frog per generation, whereas those without that phenotype on average have only 12. If we start off with genotype frequencies of .02 HH, .03 Hh, and .95 hh, what is the average excess fitness of the H allele?
Answer:
8.55
Explanation:
I n the year1908, these two men Godfrey Hardy and Wilhelm Weinberg gave a specification of the relationship between the frequency of genotype and frequencies of allele that should occur when such a population is in equilibrium
p²+2pq+q² = 1
we have,
p² = 0.02
p = √0.02
such that frequency of H is = 0.1414
2pq = 0.03
q² = 0.95
q= √0.95
such that frequency of h =0.9746
(21-12) * 0.95 =
8.55 frogs per generation
H and h will coexist.
as a research scientist you discover what you believed to be a new organism you find the organism in the event of an underwater volcano what would you need to determine about the organism in order to prove that it alive
What you would need to to determine that is to look at the "organism" to see if it has
order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. If it does then it is a organism.
This monarch butterfly has orange wings. Is orange
the genotype or the phenotype? Explain
Answer:
Phenotype
Explanation:
It's phenotype because a genotype is not a physical trait; a genotype means genes. It's phenotype because it a physical trait you can see. Lets say twins look the same on the outside but on the inside they have completely DNA. This is like how some butterflies look the same with orange wings but one might have a mutation in its genes.

CELLS: Describe the structure of a eukaryotic plant cell. Indicate the ways in
which a non-photosynthetic prokaryotic cell would differ in structure from this
generalized eukaryotic plant cell.
Answer:
A cell that is nonphotosynthetic, such as a prokaryotic bacterium, would not require chloroplasts to function.Explanation:
A broad sweeping eukaryotic plant cell accomplishes the basic functions required for plant care. It's a jumble of organelles held together structurally by the cell membrane, which is located outside of the cell wall.
What is eukaryotic cell?Plant and animal cells are eukaryotic, which means they contain nuclei. Plants, animals, fungi, and protists all have eukaryotic cells.
They typically have a nucleus organelle surrounded by a membrane called the nuclear envelope, which stores DNA.
Prokaryotes are typically simpler, requiring only a few organelles to survive. This is frequently because, as previously stated, it requires less energy.
It has DNA to contain genetic material, ribosomes to make proteins, a cell membrane, and a cell wall to protect the cell from its surroundings. While other components are produced by prokaryotes, the ones listed above are those that may be found in plant cells.
Aside from that, the non-photosynthetic prokaryotic cell requires much less energy, resulting in a cell that is much smaller and less complex than the generalized eukaryotic cell.
Thus, this way, a non-photosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell.
