In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t
Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² +  2pq+ q²  = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = \sqrt{0.35} = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.

<em>the function of epidermis is to protect the leaf
make it air tight 
prevent water loss as it is waxy
also it is transparent and allows all light to enter...
   chloroplast is required for carrying out process of photosynthesis...
    as epidermis is not specialized to carry out photosynthesis... so it does not have any chloroplast...</em>

Evgesh-ka [11]
These viral particles, also known as virions, consist of two or three parts: the genetic material made from either DNA or RNA, long molecules that carry genetic information, a protein coat, called the capsid, which surrounds and protects the genetic material. Hope this helped :)

A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and mol
mr Goodwill [35]

Answer:

Crustaceans and Molluscs play an important role in the oceanic carbon sink.

Explanation:

Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.

  • CO2 is not combustible.
  • creates carbonic acid in the oceans.
  • Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)
