Answer:
four daughter cells
Explanation:
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Sexual reproduction increases the genetic variation of a species because:
Answer:
Sexual reproduction increases the genetic variation of a species because it involves combining of genetic materials of two parents/individuals to form an offspring.
Explanation:
Sexual reproduction is a type of reproduction that involves formation of an offspring by combination of male and female gametes. Each gamete carries a haploid set of chromosomes. When gametes from both the parents combine, a zygote is formed which has a diploid set of chromosomes. So, sexual reproduction involves combination of genetic materials of two different individuals, hence, it leads to genetic variation.

Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in
Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in the amount of genetic variation in a population.
What is natural selection?Populations of living things adapt and change through a process called natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others.
Four requirements must be met for natural selection to take place: reproduction, inheritance, variety in physical traits, and variation in the number of children produced by each person.
Reproduction:
A population must procreate to produce a new generation in order for natural selection to affect it. Over many generations, people who have the characteristics that are most compatible with their environment tend to breed more than people who don't.
Heredity:
Since the genes of the parents combine to form the DNA of their offspring, heredity and reproduction go hand in hand. Natural selection must operate if parents with favourable qualities pass those traits on to their kids.
Variation in Characteristics:
Only when individuals within a community differ in their personal features can natural selection take place. For instance, different people must have varied colors in order to research natural selection on color within a population. There wouldn't be any traits for nature to "select" over others in the absence of variety in traits.
Fitness Variation:
Compared to its popular notion, fitness has a more technical meaning. Fitness in the context of evolution refers to an organism's capacity for maximum survival and reproduction. Natural selection cannot take place in a population unless its individuals have varying levels of fitness. Some people must have characteristics that make it easier for them to survive and procreate more frequently than others. Otherwise, natural selection cannot act to increase the number of people with advantageous features and decrease the number of people with undesirable qualities.

During an action potential, the rapid decrease in sodium permeability and simultaneous increase in potassium permeability is responsible for __________.
the repolarization of the cell.
Mechanism :
Action potentials are signals that are sent and received by muscle and nerve cells. Because of the negative concentration gradient in the resting membrane potential of nerve cells, there are more positively charged ions outside the cell than inside. There are more sodium ions outside the cell and more potassium ions within because these positively charged ions are sodium ions. Action potentials cause the membrane to depolarize, which is followed by the process of repolarizing the cell. The membrane potential changes and reverts to the negative value of the resting potential during repolarization. The potassium channels open and the sodium channels close at this stage, allowing the nerve cell to lose positively charged ions.

2.what is translocation ??,give the chemical equation for translocation
plss help will mark brainlest..
Transpiration is a water balance process mediated by stomata opening. Translocation is the transport process of photosynthetic substances from leaves to other tissues.
What is transpiration?Transpiration is a water balance process.
Through stomata opening and closure (which depends on how hydrated the plant is) water vapor is expelled from the leaves.
If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.By limiting water exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.
The equation to calculate transpiration is as follows,
E = Gv (Cvs - Cva)
Where,
E is transpiration.Gv is the total vapor water conductance.Cvs is the water concentration inside the leave.Cva is the air water concentration.What is translocation?Translocation is a fast and dynamic process through which photosynthetic products are transported from the leaves to other tissues of the plant to be used or stored.
This transport is done by the phloem cells through active transport or osmosis (depending on the substance).
The translocation of elements from the leaves to the roots is fast.
In conclusion,
The chemical equation for transpiration is E = Gv (Cvs - Cva). Translocation is the movement of photosynthetic products from leaves to other plant tissues.You can learn more about translocation and transpiration at

Which concept is part of the theory of evolution by natural selection
Answer:
New generations are better suited to survive than previous generations.
Explanation:
Darwin's evolutionary theory states that evolution is the slow process through which organisms change over time. Natural selection is the process by which evolution takes place. Variation in organisms, some of which offers an adaptive benefit, may be passed down from generation to generation. Better suited organisms will have a higher probability of surviving and procreating, and they will also pass on these phenotypic modifications to the offspring. Evolution is a long, protracted process because these phenotypic changes occur gradually across generations at the species level. As a result, it is anticipated that future generations would be better adapted to endure in the same environmental circumstances.
