Answer:
C.
Explanation:
When it is said that a gene is "turned off" this usually means that this particular gene is no longer making the directions that need to be followed in order to make proteins. Therefore the proteins that are needed for a specific job, such as tolerating lactose, are not being produced. So the answer in this question would be that the RNA for that gene is not translated into protein.

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.
They should consider that there might already be animals who have made their homes there. They should also consider whether or not the area is polluted as that could cause bad health effects in the park visitors.
We can use cars that don't pollute the air and we can reduce smoking.
