Answer: Replicate its chromosomes
Explanation:
The cell in the body goes through the cell cycle regulation. There are various stages of cell cycle regulation.
Out of those stages one is G1 phase at the end of which the cell is prepared for the synthesis phase.
The cell gets supplied with proteins, increases in the number of organelles and grows in size.
This occurs so that in the next stage the cells can replicate its chromosomes and new cells are formed.
Answer:
The probability will be 25% (1/4)
Explanation:
Schilder's syndrome is a degenerative and progressive lethal disease caused by the demyelination of nerve cells in the brain and spinal cord. Since it is a lethal recessive autosomal disease, both the father and the mother have a single copy of the mutant allele, thereby the probability of obtaining a lethal combination will be:
SN X SN >>
1/2 x 1/2 = 1/4 = 25%
where N and S are normal and lethal alleles, respectivelyvely
DNA code TTACGCCA = AATGCGGT
mRNA message= UUACGCCA
DNA code ACACTCGGC = TGTGAGCCG
mRNA message= ACACUGGC
Answer:
D. The rest of the country has only evergreen trees, so autumn is much less colorful in those areas.
Explanation:
The deciduous birch forests of the eastern United States have been reducing their territory by anthropic action. Yet in Florida it still persists. In these forests, plants such as birches do not support the harsh winters and that is why they have the strategy of losing their leaves. they start to turn their yellow leaves in the fall season. In other areas of the country where there are coniferous forests, grasslands and grasslands, trees have other strategies and generally have evergreens trees.
