Help my lovlies! Why do plants in the tundra have shallow, wide roots? List the 2 reasons

2 answers:

7 0

I think its because so the plants can absorb more nutrients from the soil while being sturdy and wide so when the plant gets snowed on it doesn't break<span />

They have shallow, wide roots:
To cover as much ground as possible, so the plant can absorb a sufficient amount of water before it freezes, and because the permafrost prevents the plants roots from going further down into the ground. <span />

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p

vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt x tt

Offspring = Tt Tt tt tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt x tt

Offspring = Tt Tt tt tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

Art [367]

<h2>Protein sequence</h2>

Explanation:

The given sequence is of coding strand(5'-3' direction)

5’-ATGTTGAAAATGCCGTAGAGGC-3’

Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:

5’-AUGUUGAAAAUGCCGUAGAGGC-3’

According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein

AUG codes for Methionine(Met)
UUG codes for Leucine(Leu)
AAA codes for Lysine(Lys)
AUG codes for Methionine(Met)
CCG codes for Proline(Pro)
UAG codes for stop codon(Stop)

Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:

Met-Leu-Lys-Met-Pro-Stop
