Answer: Diploid; 2n
Explanation:
In many species, there are two representatives of each chromosome. In such species, the characteristic number of chromosomes is called the DIPLOID number. It is usually symbolized as 2n.
The two basic sets of chromosomes is called Homologous chromosomes, being two, it is called DIPLOID NUMBER (if one, it is Haploid number) and symbolized by 2n.
Species like man expresses the diploid number, so is a diploid specie
The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.
Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
The correct answer is option C, that is, saves species from extinction.
The Endangered Species Act is one of the most essential and efficient environmental laws of America. It signifies a willingness by the people of America to work in harmony and restore and protect the species most vulnerable of getting disappeared forever.
The act offers common sense, balanced solutions for the landowners, government agencies, and concerned citizens to preserve the endangered wildlife and their habitats. It includes three prime elements:
1. Inhibiting the listed species from getting harmed or killed
2. Developing plans to restore healthy populations
3. Safeguarding habitat important to these species survival.
