1. Some people get repeated fungal infections because they cannot destroy these dangerous microbes after their white blood cells phagocytize them. This most likely means that these people have __________ that do not work properly.

A. ribosomes
B. lysosomes
C. mitochondria
D. microtubules

is it A

2. Long structures used for cell movement are:
A. centrioles.
B. cilia.
C. flagella.
D. granules.

is it C

For question 1, the issue described suggests that there is a problem with cells being unable to destroy fungal infections even after phagocytosis. This implies that there may be an issue with the organelles responsible for breaking down and digesting pathogens. The organelles responsible for this function are called lysosomes. Therefore, the correct answer is B. lysosomes.

To determine the answer to question 2, we need to consider the structures involved in cell movement. Among the given options, centrioles are involved in cell division, granules are not directly involved in cell movement, leaving us with cilia and flagella. Cilia are short, hair-like structures that are found in large numbers on the surface of cells and are involved in various functions, such as moving fluids or substances across a cell's surface. Flagella, on the other hand, are long whip-like structures that are typically found in fewer numbers and are involved in cell propulsion, such as the movement of sperm. Based on this information, the correct answer is C. flagella.
