Answer:
The description which is correct is:
<u><em>Species make up populations which makes up communities.</em></u>
Explanation:
In biology, species can be described as organisms which can interbreed to form fertile offsprings. Members of a species share many common characteristics. Example of species includes all human beings on earth.
In biology, a population can be described as the number of organisms of a species which are living together in a habitat at a particular time. These organisms have the capability to interbreed and produce fertile offspring.
The organisms present in different populations in an area at a particular time make up a community. For example, a population of birds, a population of insects, a population of plants that live in a certain area at a particular time make up a community.
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
Point Mutation !! It is a mutation affecting only one or very few nucleotides in a gene sequence.
