Answer:
Thin walls easily allow water, oxygen, carbon dioxide, and other nutrient and waste substances to exchange between blood cells and the surrounding tissue better.
Explanation:
Answer:
Population genetics
Explanation:
Population genetics refers to the study of distribution of genetic traits and the allelic changes occurring in a population that is variations in the alleles and genotypes.
A population that is freely interbreeding has a collection of genes and alleles called a gene pool of the specific population.
Each member will receives alleles from the gene pool( from its parent) and passes it to other members (offspring)
The answer is :
B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell.
The DNA has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.
Explanation:
The nucleus is a membrane-enclosed organelle located in most eukaryotic cells. The nucleus is the largest organelle in the cell and includes most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it proceeds up just a small portion of the cell's overall DNA content. Inside its fully enclosed nuclear membrane, it contains the preponderance of the cell's hereditary material. This material is designed as DNA molecules, along with a family of proteins, to form chromosomes.
