<span>The correct answer is testes. Gametes are sex cells, meaning that when the sex cell from a male joins with the sex cell from a female, reproduction occurs. In males, the sex cells are sperm and in females, they are eggs. The formation of these sex cells occurs in the testes for males and in the ovaries for females. So, the second option is incorrect because ovaries belong to females, gametes are incorrect because they are the product of the gamete formation organs, and the last option is incorrect because oogonia is a female sex organ for a specific type of algae. </span>
Answer:
For example, the biceps muscle, in the front of the upper arm, is a flexor, and the triceps, at the back of the upper arm, is an extensor. When you bend at your elbow, the biceps contracts. Then the biceps relaxes and the triceps contracts to straighten the elbow.
Answer:
Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.
Explanation:
Since plasma cells make your antibodies, they need to produce a lot of protein. Also because the nucleus makes a lot of products to make proteins you need a large Golgi Body. How ER's relate to this: to do protein synthesis you need ribosomes and to have ribosomes you need the rough ER!
Answer: Cell
Explanation: Cells the structural and functional unit of living organisms. They are the building blocks of all living things. Humans are made of several billions of cells. Cells provide structure for the body, cells take in nutrients, convert the nutrients to energy to perform its functions.
