Which of the following describes how dna provides evidence to support that life changes over time?
a. some animals exhibit similar structures, possibly due to a common ancestor.
b,. some animals exhibit similar stages of embryonic development.
c. some animals exhibit structures that are no longer used for any purpose.
d. some animals exhibit similar biological proteins.

Option D

Explanation:

The replication of DNA produces a specific type of protein and the protein are functional protein. Specific proteins serve special function.

Pressence of same type of protein in the organism shows that there is a relation between the two organisms having same type of protein.

Both the organisms have same recent common ancestor and that why they have similar biological proteins.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
