The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell

Yuliya22 [10]

Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.

CELL DIVISION:

Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.

According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.

In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.

You are excited because your lab is studying the first microorganisms retrieved from Mars! Interestingly, their genetic material

Oliga [24]

Answer: The maximum number of amino acids that could be coded is 2

Explanation:

A codon in this microorganism is 2 bases instead of 3 bases .
In order to encode a protein a sequence requires a start and stop codon

If you assume no start codon: then only 2 bases would make up the stop codon.

This leaves 4 bases which is 2 codons. This would encode 2 amino acids.

If you assume a start and stop codon, then each codon would be allocated 2 base pairs each = 4 base pairs
This only leaves 2 base pairs, a single codon which would only code for 1 amino acid

Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)
