Answer:
Upon nutrient limitation, budding yeast will produce daughter cells less than 20% of the mother cell size. This asymmetric division may select for growth functions that are efficient over a larger range in cell sizes, such as exponential growth. In turn, efficient growth over a large size range lessens the pressure to have precise size control.
Explanation:
In wild-type cells growing in nitrogen-rich medium, the size threshold to enter mitosis is high, and the G1/S size control is cryptic because cell division produces daughter cells with a size greater than the minimum required to initiate S phase. In these conditions, G2 is long and G1 is short. However, the cell size threshold to enter mitosis is greatly reduced when wild-type cells are shifted to medium with a poor nitrogen source, such as minimal medium with proline, isoleucine, or phenylalanine. In these conditions, wild-type cells initiate mitosis at a reduced cell size, generating two daughter cells that are smaller than the critical size threshold required to progress through G1/S
one of which rolls its dung balls during the day and rests at night. The other rolls its dung balls at night and rests during the day. These species will not breed because of <u>Temporal isolation.</u>
- When two species are divided based on when they operate, it results in the phenomena of temporal isolation.
- The difference in their mating seasons or the time of day they are active could be the reason for this divergence.
- This type of isolation reduces the likelihood of interbreeding between the two species, which may eventually lead to speciation.
- Because two species of beetles in the provided question are active at separate times of the day and do not cross-pollinate, it can be said that these species are exhibiting a temporal form of isolation.

It is phenotype becoz smoothness is outer character
The correct answer is option B
A cladogram can be defined as a diagram that uses cladistic to show the relation among the organisms. Many evolutionary trees can be made from a single cladogram but the cladogram cannot be considered as the evolutionary tree because it does not shows that how the ancestors of the species is related to the descendants.
The cladogram of reptiles are made.
