Answer:
True
Explanation:
B cells are involved in the humoral immune response and T cells are involved in the cell-mediated immune response. Class 1 MHC molecules are found on all uncleared cells and class 2 MHC molecules are found on macrophages, B cells, and activated T cells.
1. Both are caused my osmosis
2. Both involve in the destruction of the cell (plasmolysis occurs in place cell walls and heamolysis occurs in red blood cells of animals
The correct answer is bpa in bottles affects particular glands.
An endocrine disruptor is a chemical which at certain doses can disrupt the normal endocrine function of the organism. The effects of an endocrine disruptor can be quite severe, from birth deficits and cancerous tumours to developmental disorders.
One of the most commonly detected chemicals in the human body is bisphenol A (BPA), a material used in the production of plastics. It is considered an exoestrogen, meaning that it possesses hormone- and estrogen-like properties. These properties affect specific glands of the human body causing reproductive and neurological problems, obesity, diabetes and some types of cancer.
Feedback from estrogen is a mechanism that the human body uses to control the FSH release from the gonads. This is not considered an endocrine disruptor since it is a natural mechanism. In addition, iodine is a chemical element essential for the synthesis of thyroid hormones. Any lack of it is not considered an endocrine disruptor. Finally, calcitonin is a hormone produced in humans by specific cells of the thyroid gland and it is not considered an endocrine disruptor.
It makes up the biome ecological unit
Answer:
A
Explanation:
We can't see the graph, but I think I found the worksheet online, and so the graph is attached.
The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion
The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.
The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic
The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
