Answer:
DNA is a double-stranded molecule, while RNA is a single-stranded molecule
Explanation:
The answer is
C) Abyssopelagic Zone
This is the deepest zone of the zones listed, with depths up to 6000 meters.
the higher the depth, the larger the amount of water bearing down on the area, the higher the water pressure.
Answer:
False
Explanation:
Gregor Mendel, who was referred to as the FATHER OF GENETICS, discovered the principles that governs heredity. One of those principles which he called LAW OF INDEPENDENT ASSORTMENT states that the alleles of a gene randomly segregates into gametes independently of the alleles of another gene. This means that during gamete formation (meiosis), the separation of the alleles of one gene doesn't affect the separation of the alleles of another gene.
Mendel discovered this principle when he worked with two genes that was responsible for two distinct characters. Hence, in a cell that contains two genes responsible for two different characters in the organism, independent assortment will always occur during gamete formation. Although, in an organism that is homozygous for both traits (AABB or aabb), only one type of allelic combination will be produced in the gamete. However, the alleles will still randomly align and separate independently of one another during Metaphase and Anaphase stages of meiosis.
Answer: A.prey
Explanation:
The prey is the resource for which the two different flea species in the same forest would likely to compete with each other. This is because of the fact that prey is the source of food which is the basic need required for the survival of both the flea species. Other needs like mates, space and hosts are secondary needs, the two flea species would probably survive without them. If the prey population is small then the competition among the members of the two different flea species will increase.
Answer:
a) ![0.58](https://tex.z-dn.net/?f=0.58)
b) ![0.598](https://tex.z-dn.net/?f=0.598)
c) ![0](https://tex.z-dn.net/?f=0)
Explanation:
Given -
Total sample i.e n ![= 18](https://tex.z-dn.net/?f=%3D%2018)
Probability (p)
% ![= 0.03](https://tex.z-dn.net/?f=%3D%200.03)
We will use binomial distribution theory for determining the probability of mutated sample
Let X be the number of mutated sample
a) No samples are mutated i.e ![X = 0](https://tex.z-dn.net/?f=X%20%3D%200)
![P(X=0) = 0.03^0 * 0.97^{18}\\= 0.5779 = 0.58\\](https://tex.z-dn.net/?f=P%28X%3D0%29%20%3D%200.03%5E0%20%2A%200.97%5E%7B18%7D%5C%5C%3D%200.5779%20%3D%200.58%5C%5C)
![0.58](https://tex.z-dn.net/?f=0.58)
b) At most one sample is mutated
![P(X=0) = 0.58 + 0.03^1 * 0.97^{17}\\= 0.598](https://tex.z-dn.net/?f=P%28X%3D0%29%20%3D%200.58%20%2B%200.03%5E1%20%2A%200.97%5E%7B17%7D%5C%5C%3D%200.598)
c) More than half the samples are mutated.
![P(X = 10) + ........+ P(X = 18) = 0](https://tex.z-dn.net/?f=P%28X%20%3D%2010%29%20%2B%20........%2B%20P%28X%20%3D%2018%29%20%3D%20%200)
