Which of the following is the best definition of anaerobic respiration?

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

Conifer Leaf.  

Microphyll Leaf.  

Megaphyll Leaf.

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

The absolute zero is the temperature at which molecular motion ceases i.e translational kinetic of molecules become zero, but the molecules possess the potential energy, according to the Kinetic theory of gases. Thus, the absolute zero is not the zero energy temperature.

Answer:

1. Mutations in protein-coding genes and regulatory DNA contribute to evolution if the organism carrying them survives and_c. reproduce. Mutations in a_a. gene lead to different effects. For example, a mutation may change the _h. function of the protein or the protein will no longer be produced.

2. Mutations within a_i. regulatory sequence may lead to major changes in_g. body form, for example, if a Hox gene is affected. Moreover, if a transposable element inserts here, it may lead to a decreased or increased_d. protein production. This may impact the organism and if passed on to the offspring, become_e. inherited. The result of these events may eventually lead to increased fitness and the formation of new species.

Explanation:

Mutations can be defined as genetic changes (nucleotide changes) in the genome sequence of an organism. Mutations can be beneficial, neutral or deleterious (depending on their effects on the adaptive fitness of the individual). Mutations that occur in the somatic (body cells) will not be inherited, whereas mutations in the germinal (gamete) cells can be passed on to the next generations. Moreover, Hox genes are major developmental regulators involved in a wide variety of aspects of animal development. In consequence, changes in the expression level of Hox genes caused, for example, through 1-mutations of their regulatory sequences, such as promoter sequences, or 2-the insertion of transposable elements, may lead to conspicuous phenotypic changes by affecting protein production. Eventually, these mutations may confer an adaptive advantage.

Answer:

Answer to the following question is as follows.

Explanation:

Budding is indeed an asexual reproduction method in which an individual emerges from a reproductive anatomical site of the parent organism. During budding, a genetically identical new creature develops connected to the parent Hydra's body before eventually separating. A bud emerges as an extension of recurrent cellular division at one specific location during the budding process.

Answer:

a molecule called DNA (deoxyribonucleic acid) is passed from adult organisms to their offspring during reproduction.

DNA molecules transfer heredity from parents to offspring.

DNA or deoxyribonucleic acid exists considered the genetic material that transmits genes from Parents to offspring. DNA exists found almost inside every cell. The molecular structure of DNA existed discovered by James Watson and Francis Crick in the year 1953. They obtained Nobel Prize for it in the year 1962.

DNA exists created up of molecules called nucleotides. Each nucleotide contains three elements: a phosphate group, which stands for one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base.

C. bacteria

Explanation:

Humus is rich in organic matter and also is abundant in inorganic mineral nutrients.

(*) Sorry for my late answer but I hope this helps others that are looking for this.

100% in the test  ;)

Humus is made of Earthworms, nutrients and bacteria. So, the correct options are A, B and C.

Humus is the soil's black organic material that results from the breakdown of plant and animal debris. It is a type of organic material for soil. It has a lot of nutrients and keeps the soil moist. The Latin word for "earth" or "ground" is humus.

Humus is described as a dark organic substance that develops in soil as a result of plant and animal debris decomposing. It is organic and dark in colour because carbon has accumulated there. It contains elements that are crucial to maintaining healthy soil. Earthworms, nutrients, and microbes make up humus.

Because humus is a feature of loamy soils, the high concentration of nutrients in the soil is caused by humus. Humus reduces a substance's porosity by obstructing the pores that permit the passage of water and air.

Therefore, the correct options are A, B and C.

Answer:

1 monosomy

2 trisomy

3 Down syndrome

4 Turner syndrome

5 non-disjunction

6 metaphase

7 twenty-two

8 largest (chromosome 1)

9 smallest (chromosome 22)

10 karyotype

Explanation:

Non-disjunction during meiosis I or II occur when homologous chromosomes or sister chromatids refuse to separate. This makes the resulting gametes to have too many or too few chromosome numbers in their genomes.

A gamete with too few chromosome number that participates in fertilization with a normal gamete will result in a zygote with abnormally less chromosome number. This situation is referred to as monosomy. Whereas, the fusion of a gamete with too many chromosome number with a normal gamete will result in a zygote with too many chromosome, a situation known as trisomy.

The manifestation of monosomy and trisomy in humans results in Turner and Down syndromes respectively.

Humans have 23 pairs of chromosomes out of which a pair determines maleness or femaleness - the sex chromosome. Other chromosomes are referred to as autosomes. Hence, there are 22 autosome pairs and 1 pair of sex chromosome.

Chromosomes are studied by karyotyping, a process that involves photographing chromosomes at the metaphase stage of the cell cycle, cutting them out, and then arranging them in decreasing order of size.

7. Masked

8. Dominant

Please find the missing answers to the questions in BOLD.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

Answer:

hyposmotic

Explanation:

Body fluids are in contact with cells. Cells are surrounded by a semi-permeable membrane, through which can pass certain solutes. If the concentration inside the cells is different from the body fluids, the water molecules will move from the more concentrated compartment to the less concentrated one. This process is called osmosis.

If the body fluids are more concentrated than cells, the solution is called hypertonic (body fluids are hyperosmic). If the body fluids are less concentrated than the cells, the solution is called hypotonic (body fluids are hyposmotic).

Answer:

- When a neuron is stimulated and sodium channels open, the process of depolarization has begun.  

- Structures of the nervous system surrounding, but not part of the central nervous system are part of the peripheral nervous system

- Two consecutive neurons communicate at a synapse, where they physically come together.  

- Endorphins are a group of natural chemicals that reduce the perception of pain.  

- Supporting cells of the nervous system are collectively called neuroglia

- When potassium channels have been open long enough to go below resting membrane potential, hyperpolarization has occurred.

Explanation:

Neurons undergo depolarization in response to diverse stimuli (e.g., heat, light, electrical, chemical, etc). The depolarization occurs when sodium (Na+) ions pass through specific channels  (i.e., open voltage-gated Na+ channels) into a neuron, which causes an increase in the positivity of membrane potential. On the other hand, hyperpolarization occurs when potassium (K+) channels remain open and Na+ channels reset, thereby producing an increase in negativity of membrane potential. The peripheral nervous system (PNS) is composed of the cranial nerves, spinal nerves, peripheral nerves, and neuromuscular junctions, which connect the Central nervous system (CNS) to the organs, limbs, and skin. Endorphins (e.g., serotonin) are polypeptides secreted by the pituitary gland and CNS to relieve stress and pain. Neuroglia refers to a class of neural cells that have ectodermal (e.g., astroglia, peripheral glial cells) or mesodermal (e.g., microglia) origins. Neuroglia cells are involved in diverse roles, including, among others, the formation of the blood-brain barrier, homeostatic support, provision of nutrients for neurons, structural support to nerve cells, etc.

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.

Answer:

In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds

Explanation:

In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.
