Answer:
b. neuron, nerve tissue, brain, nervous system, human
Explanation:
Neurons are the structural and functional units of nervous tissue. Each neuron has a long axon, a metabolic center (soma) and short dendrites. Neurons and neuroglia are the major cell types that together constitute the nervous tissue.
The brain is an organ made of nervous tissues and is a part of the central nervous system. The central and peripheral nervous systems together make the nervous system of the human body.
The nervous system along with many other organ systems such as the digestive system, respiratory system, cardiovascular system, etc. together make the human body.

Answer:
d. smooth endoplasmic reticulum
Explanation:
Organelles are structures found in inside the cell which carries out a specific function. Types of organelles include endoplasmic reticulum, Golgi body, ribosomes, nucleus etc. The function in the question is protein synthesis.
Ribosomes are the sites of protein synthesis in the cell of living organisms.
- The nucleus is involved in the synthesis of protein because it directs all the cellular processes in a cell including protein synthesis.
- Rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum whose surface is attached to by ribosomes, hence, giving it its rough surface. Since ribosomes (organelle for protein synthesis) are attached to the RER, the RER are involved in protein synthesis.
- Golgi bodies are organelles that functions to package, process and sorted the proteins produced in the ribosomes.
- The smooth endoplasmic reticulum (SER) are NOT involved in the synthesis of protein because they have no ribosomes attached to their surface. Instead, they are involved in lipid synthesis.
<span>None of the above. All of the following affect
metabolism at some point in an individual's life. As a person ages, metabolic
rate generally slows down because of muscle tissue loss, and some hormonal and
neurological changes. Gender also affects metabolism because men are generally
larger in size than women that is why they tend to have faster metabolisms than
women. Genes or inherited traits from parents also affect metabolism, the rate
at which the body goes is dependent on inherited traits from parents, also the
diseases that come with abnormal genes can affect metabolism. Temperature can also
affect metabolism because the body adjusts to maintain its normal temperature
which can either increase or decrease metabolic rate.</span>
