Division of labour occurs even at cellular level. Explain this statement.
OleMash [197]
Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.

An example of an epigenetic change is
Oksana_A [137]

Answer:

The correct answer is option d.

Explanation:

An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.  

One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.  

In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.

What is mostly likely elevation of the mountain below
solniwko [45]
From the contour line that is a combination of two line segments that connect but do not intersect, 500 and 750 represent elevation on the topographic map. There are 5 contour lines in between the given elevations 500 and 750, therefore, the contour interval is 50. Since the peak of the mountain is 2 contour lines from 750, the elevation of the mountain is 850. Hence, the answer is 871 meters.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized to produce F2. If the capital lette
Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE
