Answer: Option A) Exocytosis
Explanation:
Unlike the other pathways mentioned, exocytosis involves the outward movement of outside the cells. This is vital in the removal of waste products generated within the cell.
Thus, exocytosis is the answer because it expels materials out of the cell, rather than deliver materials to lysosomes
In a chemical reaction, a reactant bonds to an enzyme at a region known as the Active Site.
Answer:
The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.
Explanation:
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:
p + q = 1
r-6 + R = 1
0.2 + 0.8 = 1
Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64
The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04
And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32
Answer:
In the animals control and co-ordination is done by the nervous system and endocrine system whereas in animals nervous system is adequately developed and consists of brain, spinal cord and nerves; in animals hormones are secreted by endocrine glands.
