Which of the following is the main function of centrosomes in animal cells?

A. Organelle trafficking

B. Pathogen digestion

C. Microtubule organization

D. Cytoplasm formation

Answer Explanation:

Centrosomes are small structures that are found near the nucleus of animal cells. They consist of two centrioles that are surrounded by a protein matrix called the pericentriolar material. The main function of centrosomes is to organize the microtubules, which are long, hollow tubes that form part of the cytoskeleton. Microtubules are involved in many cellular processes, such as cell division, cell movement, and intracellular transport. Centrosomes act as the main microtubule-organizing centers (MTOCs) in animal cells, meaning that they nucleate and anchor the microtubules

Therefore, the Correct Answer is C.

Q #1: Which of the following is the approximate threshold value for mammalian neurons?

A. +35 mV

B. -55 mV

C. 0 mV

D. -80 mV

Answer Explanation

The approximate threshold value for mammalian neurons is -55mV.
Q #2: Which of the following reasons explains why it is important for new scientific findings to be published?

A. Publishing findings will help scientists become more biased.

B. This prevents other scientists from performing similar tests.

C. Scientists will get paid if their findings are published.

D. Other scientists can validate or disprove the findings.

Answer Explanation

One of the essential aspects of scientific inquiry is the communication of results to peers and the public. Publishing new scientific findings allows other scientists to review, replicate, or challenge the methods and conclusions of a study. This way, science can advance by building on previous knowledge and correcting any errors or inconsistencies.
Q #3: Which of the following is a group that can be measured against the experimental group?

A. Manipulated

B. Responding

C. Variable

D. Control

Answer Explanation

The experimental group is the group that receives the treatment or intervention in a scientific study. To evaluate the effect of the treatment, the experimental group is compared to another group that does not receive the treatment. This group is called the control group. The control group serves as a baseline or reference point for the experimental group. The control group should be as similar as possible to the experimental group in all other aspects, except for the treatment
