enyata [817]
Yes, Only bacteria can convert molecular nitrogen, into a form which can be utilized by other living beings such as plants. The nitrogen fixed by the bacteria, by this process, become available to the plants, which uptakes it, for their own growth, and is also accumulated in their seeds. Further, leguminous plants have nitrogen-fixing bacteria associated with them in synergy. They provide the plant with additional nitrogen, and in exchange obtain nutrients from the plant, for their growth and division.

In order for transcription to happen, DNA must
nalin [4]

Answer: <u>Unwind </u>

Explanation: Transcription is a process where a DNA strand is used to make a copy of mRNA. A complementary mRNA strand is made from the DNA strand. This mRNA is then later used to make proteins. In this process the junk information, present in DNA in form of introns is also spliced.

DNA is a double stranded structure, which is present in helical structure and both the strands are twisted together. In order to make the mRNA copy with the help of the enzyme RNA polymerase, DNA must open up. Then only RNA polymerase will be able to access the nucleotides of DNA.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What i
zavuch27 [327]

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

p^{2} + 2pq + q^{2} =1

p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\

Thus, the individuals homozygous for the allele can be calculated by q^{2} = (0.7)^{2} \\= 0.49

What happens last after a water soluable hormone approaches it’s target cell
yuradex [85]

Answer:

After the water soluble hormone approaches its target, the last thing that happens in change in cell activity and the hormones send a signal/message to the original hormone.

Explanation:

Water soluble hormones easily attach themselves to the cell. These water soluble hormones are made up of amino acid. Amino acid are basically proteins which are easily soluble in water.

These water soluble hormones cannot enter the cell membrane of the cell because they are made up of fat cells.
