Alveoli are found in lungs and exchamge O2 and Co2 !!
so answer is last one !!
<h2>Answer:</h2><h3>the majority of blood volume consist of PLASMA.</h3>
- The environment needs to change in order to natural selection to occur.
Reason:
Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
2. Population has some genetic variations.
Reason:
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:
mutation and random mating between organisms
3. Nature select organism with specific traits to survive and reproduce.
Reason:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
a atmospheric rock is the "answer" sorry just need some points
Three out of four of their offspring will be white when Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white. Thus, the correct option is B.
<h3>
What is law of dominance?</h3>
A trait is represented by two contrasting factors of a gene in a heterozygous individual, while the homozygous individual has two copies of the identical factors, according to the law of dominance. As a result, the heterozygous rabbit's genotype will be Bb, whereas the homozygous recessive rabbit's genotype will be bb.
