Answer:
All organisms depend on the production of energy, in order to function. Most of them make use of glucose as the main material for extracting the necessary energy to survive. However, some of these organisms will use, or not need to use, oxygen, in conjunction with glucose, in order to be able to generte ATP, the molecule that is responsible for powering up a living organisms´ cellular activities. In order to achieve this formation of ATP, then, all organisms will need at least glucose present, and most, will require also the presence of oxygen, to generate ATP. The two mechanisms by which ATP is produced, then, are: aerobic and anaerobic respiration.
In similarities, these two processes have several. First, the two require a substrate to work with, which is glucose, or a source that can yield glucose molecules. The second is that both mechanisms are used to provide ATP to living organisms, and three, they both are ways to acquire energy.
However, there are also differences. The most important being that aerobic respiration requires not just glucose, but also oxygen, in order to produce ATP, while anaerobic respiration just needs glucose. The second most important is that anaerobic respiration yields much less ATP molecules than aerobic respiration. And the third difference is that while from the chemical reaction in aerobic respiration an organism gets water and carbon dioxide, the second reaction in anaerobic respiration yields lactic acid and also ethanol (fermentation).
Answer:
1. the primary mechanism to maintain homeostasis is negative feedback.
2. When exposed to hot conditions, sweating is one of the primary methods your body uses to control its temperature.
3. Sweat, as it evaporates, helps cool the skin. Blood vessels feeding the skin also dilate, which allows warm blood to flow to the skin surface. This helps remove heat from the body core.
4. Bacteria can also disrupt homeostasis in your body, and can make you sick.
5. In response to infection, your immune system springs into action.
6.
why are u asking it........
Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
