Answer:
The correct answer is - DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Explanation:
The chromatin reticulum is present in the undivided cells, which condenses to form a rod-like form called a chromosome. The chromosome consists of DNA structures.
That DNA is a double helical structure and acidic in nature and it is present inside the chromosomes as it is coiled around histone protein which is basic in nature. That allows the DNA to fits in the nucleus.
Thus, the 3rd statement is the correct answer.
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer:
I believe the answer is number 3: an increasing amount of the lighted side of the Moon.
Explanation:
When the Moon changes from new Moon to full Moon, the lighted side is shown more and more, increasing from the right side to the left until you can see the whole lighted side. This would mean you would see an increasing amount of the lighted side of the Moon.
