A, C & D
Usually as cells, and even organisms get larger, their surface area to volume ratio decreases. This is why it is important for cells to retain their relatively small size to keep a larger surface area to volume ratio.
Explanation:
A larger Surface area to volume ratio ensures that the cell can efecitnyl take up nutrients and excrete toxic metabolites. This ensures that the biochemical activities in the ell continue effectively to support the life process.
If cells were too large, it would take time for important substances like nutrients and oxygen to reach the center of the cell. On the other hand, toxic metabolites would accumulate in the cells because the rate at which they are eliminated is very low.

The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:
![\Delta H = Q-W](https://tex.z-dn.net/?f=%5CDelta%20H%20%3D%20Q-W)
Where;
is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;
![\Delta H =874-159\\\\\Delta H = 715](https://tex.z-dn.net/?f=%5CDelta%20H%20%3D874-159%5C%5C%5C%5C%5CDelta%20H%20%3D%20715)
Change in internal energy (ΔH) = 715 Joules.

Also, intersexual selection, or mate choice, occurs when females choose between male mates. Traits selected by male combat are called secondary sexual characteristics (including horns, antlers, etc.), which Darwin described as "weapons", while traits selected by mate (usually female) choice are called "ornaments".
The answer is a. correlational research.
In this scenario, you only do observation of one event and trying to find a link between them. This method is good for finding correlation, but not for causation.
Because you only observe the subject without intervention, it shouldn't be experimental research. What you observe is only one condition, so there is no control subject that get different condition.
