The answer is <span>c. nephron, villi, alveoli.
</span>Capillaries are the smallest of all blood vessels with very narrow diameters (5-10 micrometres) and thin walls. Capillaries are very close to the cells in different organs and their thin walls enable an exchange of molecules between the cells. So, to found out w<span>hich of the structures rely on capillaries, we must look for the smallest functional units of the tissues which are small enough to communicate with capillaries and, as well, to be the functional units:
a, b, d. none of those is </span>the smallest functional unit<span>, some are cells, tissues, organs.
c. nephron is the basic functional unit of kidneys, villi are </span>the smallest functional units of the intestine, and alveoli are <span>the smallest functional units of the lungs.</span>
Answer: Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.

BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
descriptive method of investigation
It cannot be used to correct variable or be used to determine causes and effect of the problem
experimental method of investigation
It might create an artificial situation that do not always represent the real life situation
comparative method of investigation
It is not easy to control other variables that might influence the study

Answer:
AB, Ab, aB, ab
Explanation:
According to the law of independent assortment two genes separate differently from each other during gamete formation process. This means that the gametes have equal probability of receiving each combination of the alleles.
Here, two genes "A" and "B" are present in heterozygous AaBb genotype. They assort independently of each other. So, the combinations of A and B would result into four types of gametes:
AaBb = AB
Ab
aB
ab
