A process that increases genetic diversity during meiosis

Answers

Answer 1

Answer:

During the prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.

Explanation:

Answer 2

Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

What is meiosis?

During the prophase of meiosis I, homozygous chromosomes are next to one another and exchange genetic material.

There could be a heterozygous state for a gene if two distinct alleles are present on the same genetic locus on homologous chromosomes. (For instance, an allele for antigen A on one chromosome and an allele for antigen B on another; both are used to determine the ABO blood group.)

Numerous genes are linearly ordered on chromosomes; as a result, some of them may still be heterozygous. (The same person may be heterozygous for the ABO blood group, iris color, and sickle cell anemia).

Therefore, Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

the rate of photosynthesis can be affected by several factors, such as light intensity, temperature ,water, and carbon dioxide. describe how the lack of water in an environment can affect the amount of carbon dioxide absorbed by the plant

Answers

Answer:

Plants need water, so that their guard cells can fill up and become turgid which would allow the stomata to open and gas to exchange. If there is not much water, not much gas exchange can occur hence not much Carbon dioxide can be taken in.

Explanation:

Plants require water for the process of photosynthesis. Plants need water so that their guard cells can fill up and become turgid. This allows the exchange of gases in the stomata.

How does water affect photosynthesis?

During photosynthesis, the plants take in carbon dioxide and water molecules from the air and soil particles. Within the plant cell, this water is oxidized to generate oxygen gas, meaning that it loses electrons, while the carbon dioxide gas is reduced in the chloroplast of the plant cell by gain of electrons to produce carbohydrates. This process transforms the water into oxygen gas and the carbon dioxide gas into glucose molecules (carbohydrates).

Plants need water, so that the guard cells in the plant can fill up and become turgid which would allow the stomata to open and exchange of gases. If there is not much water present in the guard cells, not much gas exchange can occur hence not much of the carbon dioxide can be taken in from the atmosphere.

Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.

Answers

Answer:

I think its C but I am not sure, I hope this helps :)

Explanation:

The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.

Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.

In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.

Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.

In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Answers

Answer:

in my oppinion its call a  

source of pergisol

Explanation:

What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.

Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

Explanation:

The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

DNA and complementary base pairing

The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.

In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).

According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.

In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Describe the following types of cell signaling:

Autocrine:

Juxtacrine:

Endocrine:

Paracrine:

Answers

Answer:

Autocrine:Autocrine signaling means the production and secretion of an extracellular mediator by a cell followed by the binding of that mediator to receptors on the same cell to initiate signal transduction. A well-characterized form of autocrine signaling is the secretion of IL-1 by macrophages.

Juxtacrine:In biology, juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact. ... A membrane ligand (protein, oligosaccharide, lipid) and a membrane protein of two adjacent cells interact.

Endocrine:The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

Paracrine:Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells. ... However, the exact distance that paracrine factors can travel is not certain.
