A process that increases genetic diversity during meiosis
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:
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.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

The weight of an object can change because of the forces acting on the object. Which force causes the weight of an object to change?
Gravity
Gravity is a force exerted by the centre of earth which pulls objects towards earth centre[tex]\\ \tt\hookrightarrow F_g=mg[/tex]
m is massg is acceleration due to gravityGravity is the driving factor behind changes in an object's weight. Gravity is the force that draws two mass-containing objects together. Gravity is the force that pushes items toward the planet's core on Earth. Hence the correct option is A.
The force with which an item is drawn towards the surface of the Earth by gravity is its weight.
An object's weight can alter if the gravitational force pulling on it changes. An object's weight will vary, for instance, if it is transferred to a location with a different gravitational field.
The weight can also change depending on how far away from the planet's or celestial body's core it is.

Answer. It means amoeba has single cell,unicellular. ... Amoeba will functions every thing with the help of that single cell. Humans have many cells which functions multiple functions ( nerve cells,muscle cells,brain cells).
Explanation:
Answer:
Hi E 16
Amoeba are unicellular organisms where as humans are multi cellular organisms
It means amoeba has single cell,unicellular. we has multi cells means more than 2 cells.
Amoeba will functions every thing with the help of that single cell.
Humans have many cells which functions multiple functions (nerve cells,muscle cells, brain cells).

What part(s) of photosynthesis would the plant not be able to perform if there were no rain?
Answer:
When plants are not watered properly they wilt. ... When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn't get enough water, the pressure inside the stems and leaves drops and they wilt. Plants also need water for photosynthesis.
Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
When a plant does not receive enough water, the water pressure inside the stems and leaves decreases and the plant wilts. Water is also required by plants for photosynthesis.
Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Therefore, Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.

In your opinion, what are the three most important molecules needed for the production of ATP? Explain your reasoning.
To produce the energy required to drive ATP synthesis, the human body requires three different types of molecules: lipids, proteins, and carbohydrate.
What molecules are required for the production of ATP?
In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
ATP is produced during aerobic respiration from glucose and oxygen, along with carbon dioxide and water.
ATP hydrolysis provides the energy needed for many essential processes in organisms and cells.
These include intracellular signaling, DNA and RNA synthesis, Adrenergic signaling, synaptic signaling, active transport, and muscle contraction.
Therefore, lipids, proteins, and carbohydrate are important molecules in production of ATP.

a cyclone
an anticyclone
a low-pressure system
Answer:
Anticyclone
Explanation:
Fair weather can usually be expected with the approach of a high pressure system or an anticyclone.
Fair weather can usually be expected with the approach of an anticyclone that is present in the second option, as the anticyclone is a high-pressure system that is characterized by descending air.
What is an anticyclone?An anticyclone is a high-pressure system that is characterized by descending air, the descending air in an anticyclone is warmed by compression as because it prevents cloud formation and precipitation as it moves closer to the surface, an anticyclone typically brings clear skies, calm winds, and generally pleasant weather. A low-pressure system or cyclone is characterized by rising air, which creates an unstable and potentially stormy atmosphere, as the air rises, it cools and forms clouds, which can lead to precipitation and thunderstorms.
Hence, fair weather can usually be expected with the approach of an anticyclone, which is present in the second option.
