Answer:

a. leaves that close when touched.

Explanation:

Venus flytrap is an insectivorous plant. Its scientific name is Dionaea muscipula. It has a specialised system by which it traps and kills insects. Venus flytrap is an autotroph (makes its own food through photosynthesis), but it absorbs nitrogen and phosphorous from insects because the soil in which it grows lack these elements. It has steel-trap shaped leaves which secrete sweet-smelling nectar and when insects land on its leaves for the nectar insects get trapped.

In general, the protein quality in grains would be most improved by the addition of a plant protein rich in ____.?

Anastasy [175]

The appropriate response is lysine. Lysine is a basic amino corrosive. Many individuals realize that few amino acids are known as the "building squares of protein" and are required all together for a colossal number of appropriate inner capacities, including development.
There are numerous unbelievable L-lysine benefits, from its utilization as a typical treatment for mouth blisters to a potential against nervousness supplement. As is valid with most supplements accessible in supplement shape, L-lysine can be taken orally yet is assimilated best into the body when devoured through nourishment. It's found in substantial sums in different sorts of meat, beans, cheeses, and eggs.

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.
