There was a chemistry lab and they took water samples to be tested.
<span>Desertification is the cancer of the earth,” Argentine geographer Elena Abraham told IPS. “It is a process of degradation that does not manifest itself in spectacular ways but furtively advances, and by the time it is visible there is nothing to be done, and people have to move away, in search of an alternative.”</span>
Answer:
review all proposals for animal research to be sure the procedures to be used are appropriate and humane.
Explanation:
The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.
Answer:
The correct answer would be - extracellular fluid.
Explanation:
Changes in extracellular fluid helps the homeostatic mechanism to monitor and regulate the composition of the body fluids. This process involves regulatory hormones such as anti diuretic and aldosterone in order to maintain body fluids.
It is easy to regulation of the extracellular fluid than trying to regulate 100 trillion cells present in Intracellular fluids as ICF have 10% more water in comparison of ECF.
Thus, the correct answer is : extracellular fluid.
Answer:
d. maintains all reactions in a pathway near the equilibrium of each.
Explanation:
In living organisms, control processes similar to the control processes used in technology take place in a purely formal way, one can look at living beings as cyber machines. Governance and regulation are fundamental principles of the organization of the living. According to the type of signal or transmission of information, four different types of biological control processes are distinguished:
- Neural
- Hormonal
- Differential gene expression in which substrate or substrate-like effectors are signaling agents.
- Feedback and forward control mechanisms in which the metabolites themselves act as direct signals to control their own degradation or their own synthesis.
