Endocrine secretion is when a molecule(usually a hormone) is secreted into the blood. Endo as “in” the blood. Exo as “out” of the blood. You can think of it that way if it helps:)
The correct answer is: b. it doesn’t often reflect reality.
While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
Answer:
A. Water and nutrients are absorbed.
Explanation:
About 90% of water and nutrients digestion occurs in small intestine. Therefore the answer to thşs question is A.
I believe that is false. The canopy can block 95% of the light. I might be wrong about which kind of forest though.
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
