During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, i
Elenna [48]

Answer:

1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.

2.  Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.

3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.

4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.

5. Plants always produces both eggs because they are hermaphroditic in nature.

barxatty [35]
Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.

Paha777 [63]

The right answer is water.

The transformation of oxygen into water is done at the level of the mitochondria in a process called oxidative phosphorylation.

In eukaryotes, oxidative phosphorylation occurs in the inner mitochondrial membrane, specifically at the cristae of this membrane. It includes the respiratory chain, which provides oxidation of coenzymes reduced by the Krebs cycle, and ATP synthase, an enzyme capable of phosphorylating ADP to ATP from the energy released by the respiratory chain during the course of treatment. oxidation of coenzymes. This energy is stored as an electrochemical gradient across the inner membrane of the mitochondria by proton pumps that generate a proton concentration gradient during the flow of electrons along the respiratory chain. The final step of the latter is the reduction of one oxygen molecule by four electrons to form two molecules of water by fixing four protons.
