Hello, I figured that the question was missing its options so I went online to find them. Here they are:
All of the following are true of the thymus gland, except that:
A) activates B cells.
B) reaches its greatest relative size during the second year of life.
C) involutes after puberty.
D) produces T cells.
E) lies in the anterior mediastinum
Answer:
The correct answer is: A) activates B cells.
Explanation:
The thymus is a lymphatic organ that is located in the anterior superior mediastinum (a compartment in the thoracic cavity), in front of the heart, with the function to mature T cells (one of the types of lymphocytes, white blood cells very important for the functioning of the immune system).
The thymus is more active and bigger during childhood, when puberty hits it involutes and its functional tissue is replaced with adipose tissue (fat).
<u>B cells are not activated in the thymus, they mature in the bone marrow</u>.
A. Photosynthesis and cellular respiration
B. Cellular respiration and decay
C. Decay and fossil fuel formation
Explanation:
Photosynthesis, cellular respiration, decay and fossil fuel formation are all processes that are part of the carbon cycle.
In the carbon cycle, carbon in different forms moves in the environment.
- During photosynthesis, green plants use carbon dioxide gas to manufacture their own food.
- Cellular respiration release carbon dioxide as waste product into the atmosphere.
- When plants and animals dies and decay, carbon dioxide is release from their tissues by the activities of decomposers.
- Fossil fuel formation removes carbon by accumulation of the organic matter of plants and animals.
