The correct answer is option:
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.
The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.
This type of classification used to be used when classifying the protostome organisms.
In this type of organism, the oral cavity develops from the blastophore, the initial cavity in the gastrula, an early stage of the development of the embryo.
All living organisms need to take substances from their environment to obtain energy, to grow and to stay healthy
Answer:
A, Both cells will replicate their DNA.
Explanation:
During the cell division, cell passes through several phases and divides. Before each phase, the cell has to pass through the checkpoints. At these cell checkpoints, the cell receives the internal and external signals.
When the cell is arrested at G₀ phase, the cell does not divide until it receives a signal to proliferate but when the cell passes the G₁ phase, the cell will divide continuously.
In the given question, if the cells when in their G₀ and G₁ phase receive proliferation signal, the G₀ phase cell will also divide and will replicate it DNA during S phase as G₁ phase cell will do.
Thus, Both the cells will divide their genetic material.
