Answer:

Answer: Option C)  Warm air is less dense than cold air

Explanation:

Due to greater temperature of warm air than cold air, the space between intermediate molecules is more as compared to cold air. It means the warm air expands. Hence, the density of warm air is less than cold air. On the other hand, the cold air comparatively denser and sinks. Warm air is lighter and rises.

Thus, correct option is C) Warm air is less dense than cold air

hjlf

Answer:

The correct answer will be options-B and D

Explanation:

Cytokinesis is the process of cell division which divides the cellular components along with the nuclear component. The cytokinesis takes place after the completion of M-phase which differs in both animal and plant cell.

In an animal cell, the cytokinesis begins by the formation of furrow which eventually pinches off to two cells.

The formation of the furrow is a complex process and requires the microtubules like an actin-myosin ring which gets established in which the actin filaments from the ring. The myosin filaments pull the actin filaments and then forms the ring.

Thus, options-B and D are the correct answer.

For which of the following is the velocity constant (speed/direction does not change)? Question 5 options:
irina [24]
Running up a tree after running straight is a change in direction thus, although the speed is same 30mph, the velocity is different. Now, in choice B, the cat is slowing down after having escaped from the dog. This is also a change in velocity (because the speed decreases).When the cat is sitting still the whole time, its velocity is 0.0mph the entire time. That means the velocity doesn't change <span>And when the cat is running around the house, the cat is changing direction (thus velocity is different). (This is relevantly a circular motion, and acceleration is a non-zero constant, and thus veloicty of course isn't same).</span>
