An enzyme is a catalyst which means it changes the speed at which a chemical reaction occurs. It never alters the reaction in any way or changes nay chemical properties, only the speed at which it occurs and is completely absorbed in the meantime. The substrates that are reacting just have their reaction faster.
Answer:
Sea shell fossils are found in a mountain-top cave in New Hampshire.
Explanation:
Answer:
In E. coli promoter there are two consensus sequence which is located upstream to from the start site of the transcription. One consensus sequence is present at -10 and one at -35.
These consensus sequences are necessary to be recognized to start the transcription. It is recognized by the sigma factor which is a part of RNA polymerase. After recognition transcription starts.
The termination of transcription occurs by a rho protein. Rho is ATP dependent RNA stimulated helicase which disrupts the complex of RNA-DNA and terminates transcription.
<u>Complete Question:</u>
In anatomical, directional terminology, the esophagus is ------------- to the mouth.
a.Superior
b.Lateral
c.Medial
d.Posterior
<u>Correct Option:</u>
In anatomical, directional terminology, the esophagus is<u> medial</u> to the mouth.
<u>Option: C</u>
<u>Explanation:</u>
- The anatomical directional terminology is necessary to define the relative positions of different physical components.
- Devote these words to recall in order to prevent ambiguity when you research or explain the positions of various parts of the body.
- The terms consist roots, prefixes, and suffixes. The source of a word often relates to an organ, tissue or condition while the root is most often defined by the prefix or suffix.
- The center of the body or its orientation towards the west is understood as medial.
The predicated frequency of homozygous dominant rats at are: 0.11 (Option A). See the explanation below.
<h3>What is a
homozygous dominant rat?</h3>
A homozygous organism has two copies of the same allele for a gene.
If an organism has two copies of the same dominant allele, it is homozygous dominant; if it has two copies of the same recessive gene, it is homozygous recessive.
<h3>
What is the justification of the above answer?</h3>
Note that the total population of rats is: 200
Number of rats with brown fur = 112
The frequency of brown fur rats thus,
112/200
= 0.56
Note that it is also stated that the brown fur rats are dominant in relation to the gray fur rats. Thus, in accordance to Hardy Weinberg's equation, the frequency of the dominant rats is depicted as: p²
Thus:
p² + 2pq = 0.56
Hence, the frequency of the the Homozygous recessive gray rats is given as:
p² + q² + 2pq = 1
q² = 1 - 0.56
q² = 0.44
q = 0.663
P = 1-q
= 1 - 0.663
= 0.337
Thus the frequency of the homozygous dominant rats is:
p²
= 0.337²
= 0.1135
≈ 0.11
Therefore the correct answer is A.
