Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.

<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>
Explanation:
The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.

The right option is; Hemiplegia
Hemiplegia is the paralysis that affects one half side of the body. Hemiplegia affects an arm and a leg on the same side and it can be either left or right side of the body. Hemiplegia is caused due to injury to the brain area that controls movements of body parts such as trunk, limbs, and face. Right hemiplegia is caused by injury to the right side of the brain while left hemiplegia is caused by injury to the left side of the brain. The level of hemiplegia of paralysis differs from an individual to another and it may change over time.
