Molluscs, Echinoderm,Chordates and annelids are of a common ancestor, they are all invertebrates with COELOM.

How many chromosomes would you expect to be in the daughter cells of the mosquito after meiosis? When starting with 6​
Mrac [35]

Answer:

The correct answer would be - three chromosomes.

Explanation:

Meiosis is the type of cell division that takes place in only sex cells and called reduction division as a single parent cell divide into four daughter cell that contains a half number of chromosomes as the parent cell.

The daughter cells are always haploid and have the half number of chromosomes. If an organism has 2n number of in its parent sex cell the daughter cells after meiosis will have n number of chromosomes

Therefore, mosquito = 2n = 6

after meiosis = n = 6/2 = 3

Thus, the correct answer would be - 3 chromosomes.

olga nikolaevna [1]

Answer:

The gene cannot be transcribed and translated into a protein.

Explanation:

Turning off a gene means the gene cannot be transcribed and translated into a protein.

Turning off of genes is a form of gene regulation, a process that controls which genes are expressed or not expressed in a cell.

<u>The expression of genes requires that they are first transcribed from DNA to mRNA in the nucleus and then moved to cytoplasm where they are translated into proteins by the ribosome.</u>

Hence, a gene that will not be expressed has to be stopped from being transcribed amd translated by being turned off by the gene regulation process of the cell.

ELEN [110]

commensalism

Explanation:

Commensalism is a type of ecological interaction between two species in which one speices benefits while other is unaffected. Commensalism  also can be considered as a type of symbiosis-two species that live together. The interaction between human and its microbiota is beneficial for microbiota while it has no effects on humans.

Although, some bacteria (gut bacteria) can help in digestion. In this case, interaction with human is mutualism (both have benefits).
