Answer:
Answer of the question is explaine dbelow.
Explanation:
Rho GTPases interact with a variety of effectors to control actin cytoskeleton
reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by
the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also
regulate proliferation and cell-cycle progression, especially GuS transition.
All the cells are about to enter mitosis means they cross GuS transition, a drug that is a
potent inhibitor of RhoA activity has no affect on the cell because these cells already in
G2 phase. So, all the cells appear to be in telophase.
So, the correct choice is A. all the cells appear to be in telophase.
Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
Answer: D
Explanation: the image shows this. Let me know if I’m right.
The regulation of blood sugar is accomplished by the organ called the Pancreas. It secrets insulin, a hormone regulator. Insulin enables the sugar to get out of the blood and into the cells where it is needed for the cells to function. And also the liver removes sugar from the body by turning it into glycogen, another hormone regulator which body burns as energy.

The initially neutral environmental signals become linked to the unconditioned stimulus's motivating qualities, which might cause behavior to either approach or avoid the environment. To increase the ability to make causal claims, control and treatment group are frequently used in practice.
Similar to Pavlovian conditioning, environmental signals are frequently combined with an unconditioned stimulus that naturally elicits a response before conditioning (the unconditioned response). The neutral stimulus will eventually start to evoke reactions that resemble the unconditioned response with repetition and pairings. The unconditioned stimulus in conditioned location preference could be anything, such as food pellets, water, sweet liquid, novel toys, social engagement, drug intoxication, drug withdrawal, foot shock, illness, wheel running, copulation, or any number of other things.
