Answer:
Parasites would not want to kill their host cells immediately because they want their food source or keep getting food, not to kill their food source (host cell). Parasites live on another living host cell for their survival, they depend on host organisms to gets an energy source, without the host cell they can't live, develop and multiply.
Mostly, if the host cell dies then the parasite also can't able to grow or reproduce and it will also die. So that they don't want to kill their host's cell immediately.
1) Arithmetic density- the number of people per square unit of land
2) Physiologic density- Is the number of people per square unit of farmland.
3) Agricultural density- is the number farmers per unit of farmland.
B. subtract the frequency of the recessive allele from 1.
Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
