Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. This explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. These prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast.

The microsporidian Brachiola gambiae parasitizes the mosquito Anopheles gambiae. Adult female mosquitoes must take blood meals f
aalyn [17]

Answer:

The correct answer is B. 1, 2, and 4

Explanation:

Option no 1 is true because before maturity, the mosquitoes will not be able to cause malaria and will be easier to kill.

Option no 2 is true because in order to ensure a safe control, the Brachiola gambiae shouldn't be dangerous to other animals or insects.

Option No 3 is not true because Mosquito larvae will contain the male larvae also. As the male larvae are not harmful, hence their growth shouldn't be stopped or they should not be killed.

Option No 4 is correct because before applying any controlling measures for a problem, it should always be kept in mind that it should not have negative effects on other food systems.

Answer No 5 is false because as the females Anopheles are harmful, they should be killed. The male Anopheles are not harmful hence, they should not be killed.

if a mutation occurs in the somatic tissue, approximately how many of the gametes will carry the mutation?
Mrac [35]

None: Only those mutations that occur in the germ line and result in gametes will have a chance of being passed on to progeny. An alteration in DNA that occurs after conception.

Somatic mutations can occur in any of the body's cells except germ cells (sperm and egg) and are therefore not passed on to children. These alterations can (but not always) cause cancer or other diseases. Mutations in somatic cells are called somatic mutations. Because they do not occur in the cells that give rise to gametes, the mutation is not transmitted to the next generation sexually. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, each of 23 unique chromosomes, one of which is a sex chromosome. Somatic cells are the cells in the body other than sperm and eggs (called germ cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. Mutations in a somatic cell occur in somatic cells and are transmitted by mitosis, resulting in cancer. However, mutations in a gamete are passed on by meiosis, resulting in mutated offspring. A genetic mutation occurs during DNA replication, and chromosomal mutations occur during meiosis.

Which is a correct statement about mutation?
leva [86]

Answer: B: Mutation increase variety in a population.

Explanation:Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.
