1. Proteins are denatured which makes it impossible for them to duplicate. (Proteins, are found in DNA)
2. Differing microbial organisms have different niches.
Acidophiles= acid loving,
Thermophiles= heat loving, etc.
Does that answer you question?
Answer:
D. Water from rivers, lakes, and streams seeps into the ground and saturates it to reach the water table.
Explanation:
No time, the first three do not make sense or are wrong
Answer: The correct answer for the question is- Resistance phase.
"General Adaptation Syndrome" is a model of stress, which was proposed by Hans Selye in 1936.
This model explains stress response ( through three phases that is Alarm phase, resistance phase, and exhaustion phase) and how it is related to aging and disease of organisms on exposure to stressful situations.
According to Resistance phase ( that is a second phase of stress response) of this model, the level of stress is declined once a body gives response to the stress. After the first phase ( alarming phase), overall temperature, blood pressure, and respiration becomes high.
As the stressor situation persist, the body is required to fight against the situation continuously, which is accompanied by outpouring of hormones.
Answer:
The correct answer is: E) Lymphocytes, cytokines, macrophages.
Explanation:
Given the symptoms and how much time they took to appear, the 14-year-old boy seems to be having delayed-type hypersensitivity (also called Type 4 hypersensitivity), causing a reaction called <u>Contact Dermatitis</u>. Type 4 is the only type of hypersensitivity that does not require the intervening of an antibody to occur as it happens because of hapten-specific T cells that will generate inflammation and the tissue damage that is usually accompanied by it.
Delayed-type hypersensitivity is characterized for happening at least 48 hours after the contact with the antigen, and will involve activated T lymphocytes (specifically CD4+ Th1), which will secrete cytokines (most importantly Interferon Gamma and IL-2) thus attracting macrophages to the tissue to phagocyte the antigen and produce inflammation.
Answer: The process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. ... Scientists then test hypotheses by conducting experiments or studies.
