Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine .
It can increase the incidence of disease transmission and
food scarcity. Population density is
the number of individuals in a population per unit area. Density-dependent
factors have a greater impact at higher population densities. Birth rate and
death rate are the major factors that determine a population's growth rate.

Answer:
3. sexual selection
Explanation:
Because artificial selection is the one made by humans like dog breeds.
Disruptive selection is when extreme values for a trait in a population are favored like big and small sizes. Stabilizing is when the trait is pushed towards the average. Sexual selection is when the trait aids in competition among individuals for access to preferred mates.
The outer lining of the connective tissue that surrounds the diaphysis of a long bone and contains the blood vessels that supply the bone periosteum
<h3>Bone Structure</h3>
The periosteum (peri = "around" or "surrounding") is a fibrous membrane that covers the exterior of bones. Compact bone is nourished by the blood, nerve, and lymphatic veins found in the periosteum. At the periosteum, ligaments and tendons also connect to bones.
<h3>
What is the diaphysis' structure?</h3>
The diaphysis's walls are made of firm, the compact bone that is dense and compact. A typical long bone demonstrates the basic anatomical features of bone. The epiphysis (plural: epiphyses), which is filled with spongy bone, is the broader portion at each end of the bone. The gaps in the spongy bone are filled with red marrow.
<h3>What is the purpose of the bone's outer layer?</h3>
The outer layer contains nerve fibers that produce pain when the tissue is injured and is primarily made of collagen. Additionally, it has a large number of blood arteries, some of which have branches that enter the bone and nourish the osteocytes or bone cells.
