Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.
<h3>What is DNA?</h3>
All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.
The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.
The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

Answer:
All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.

Meiosis II is reduction division which produces four nuclei in 4 haploid cells for a total of four nuclei.
Explanation:
Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.
It comprises following stages:
prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.
metaphase II : The chromosomes are lined at metaphase plate.
Anaphase II: the sisters chromatids gets pull apart.
telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.
You can Chanel it around a town so there is no flooding
If some place needs water then you can divert the water to the specific place
Also stopping it and creating a dam can offer the positive results of inexpensive energy, increased recreation opportunity and flood control
