Answer:

well when u mess with a natural habitat it tends to do what's it's always has. like if that field always got flooded and u put a road there then obviously that road will be flooded when the time comes.

Lapatulllka [165]

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.

siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

Which graph most likely represents a rabbit population that found a new larger habitat, but then eventually experienced an
TiliK225 [7]

Answer:

The graph illustrating such a phenomenon will show a sharp curve in upward manners in the beginning but then will  grow downwards as the predation increases.

Explanation:

When a rabbit population is introduced in a habitat, the new habitat will have abundant food for the rabbits. As a result, the population of the rabbits will grow at a much faster rate and hence the graph will move sharply upwards in the beginning. But with the passage of time, the predators of the rabbits will also increase due to the abundance of their preys. More predators will feed on more rabbits and hence a slow decline in the curve will be seen afterwards.

aivan3 [116]

Answer:

The correct answer is "temporal lobe".

Explanation:

The temporal lobe is the part of the brain involved in primary auditory perception by receiving sensory information from the ears and secondary areas and translating in into meaningful units such as speech and words. It was proved since 1954 by Mishkin and Pribram that the removal of the temporal lobe part of the brain produces a severe visual discrimination deficit in monkeys. This is the case for Maria's experiment, when the monkey was not able to differentiate between the rectangle and the cylinder anymore. Therefore, it is very likely that the part of the monkey's brain that was removed was the temporal lobe.

genetics book g how do you know that only a single gene is responsible for he color diferences between these snakes?
mariarad [96]

Answer:

Here is the full question:

An albino corn snake is crossed with a normal colored corn snake. The offspring are all normal-colored. When the first generation progeny snakes are crossed among themselves, they produce 32 normal colored snakes and 10 albino snakes.

a. How do you know that only a single gene is responsible for the color differences between these snakes?

b. which of these phenotypes is controlled by the dominant allele?

c. a normal colored female snake is involved in a test cross. This cross produces 10 normal colored and 11 albina offspring. what are the genotypes of the parents?

Explanation:

First of all, in genetics, Phenotype are the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype can be determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences on these genes.

Allele, which can also be called allelomorph, is any one of two or more genes that may occur alternatively at a given site on a chromosome. Alleles may occur in pairs, or we may have multiple alleles affecting the phenotype of a particular trait. The combination of alleles that an organism carries is its genotype. If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait. If they are different, the organism’s genotype is heterozygous. A dominant allele (A) will override the traits of a recessive allele (a) in a heterozygous pairing.

(a) In the question, we have two phenotypes seen in the second generation of this cross: normal and albino. Therefore, only one gene with two alleles is needed to control the phenotypes like colour of the snakes observed. The 3:1 ratio of these phenotypes in the F2 generation will be seen only if a single gene is involved.

(b) The allele controlling the normal phenotype (A) is dominant to the allele controlling the albino phenotype (a).

(c) The male parent’s genotype is aa. The normally colored offspring must receive an A allele from the mother, so the genotype of the normal offspring of the testcross is Aa. The albino offspring must receive an a allele from the mother, so the genotype of the albino offspring of the testcross is aa. Thus, the female parent must be heterozygous Aa.
