Which of the following are the two major parts of the nervous system?

A. Autonomic nervous system and central nervous system

B. Peripheral nervous system and central nervous system

C. Peripheral nervous system and somatic nervous system

D. Autonomic nervous system and somatic nervous system

Answer Explanation:

The nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of all the nerves outside of the CNS.

Therefore, the Correct Answer is B.

Q #1: Which of the following vessels carries oxygenated blood?

A. Pulmonary vein

B. Pulmonary artery

C. Superior vena cava

D. Inferior vena cava

Answer Explanation

The pulmonary vein is the only vessel in the list that carries oxygenated blood. The pulmonary artery carries deoxygenated blood from the heart to the lungs, where it gets oxygenated. The superior and inferior vena cava are large veins that carry deoxygenated blood from the upper and lower body, respectively, to the heart.
Q #2: #OF FILTERS MASS (g) TERMINAL VELOCITY (m/s) 1 1.01 1.74 2 1.99 2.48 3 3.02 3.04 4 4.0 3.50 5 5.01 3.80 A group of students perform an experiment to test terminal velocity, which is the greatest speed obtained by a falling object. The students dropped different numbers of coffee filters and measured the resulting terminal velocity. Which of the following conclusions is supported by the data in the following data table?

A. Terminal velocity is when the force of gravity is equal to air resistance.

B. Heavier objects take more time to reach terminal velocity.

C. The greater the number of filters, the smaller the terminal velocity

D. Heavier objects fall faster than lighter objects.

Answer Explanation

Terminal velocity is the maximum speed achieved by an object freely falling through a gas or liquid. At terminal velocity, the forces acting on the object are balanced so it is no longer accelerating. Terminal velocity is achieved when the force of gravity is equal to air resistance. From the data table you provided, we can see that as the mass of the coffee filters increases, so does the terminal velocity. This means that heavier objects fall faster than lighter objects. Therefore, conclusion D is supported by the data in the table.
Q #3: 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
