The short term effect of that would be stomach problems and liver damage. And thats just for fresh water. for salt water you would get shellfish poisoning, vomiting, diaherra, etc. <span />
Answer:
The probability of the study result being subject to bias while interpreting -------- it's a YES
Explanation:
Probability of Leukemia
A. Among traced group
= 4/1,870 persons.
B. Among self-reported group
= 4/443 person.
We can deduce
A higher rate of occurrence in self-reported group which could be causesd by fear of leukemia occurrence or suspicion of their previous exposure at atomic sites
Answer:
Microscopes are often used to examine specimens which are too small to see in detail using only the human eye. Which of the following procedures should be followed prior to placing a specimen slide on the stage of the microscope?
Turn the objective lens to the lowest magnification setting.
Explanation:
Turnin of objective lens to the lowest magnification enhances visibility which would allow the lens to focus on the specimen clearly. It is always important to start with the lowest magnification.
Answer: b. It only arrest growth of vegetative cells
Explanation: An antimicrobial agent is a substance that kills o control the growth of microorganisms, for humans this is very important in medicine or agriculture among others.
This agent should act quickly and being stable that help it to make it cheaper, also should not harm humans or other host of the microbial organisms.
The agent is not useful if only kills vegetative cells because it is not preventing the reproduction of the organism specially in fungi which use sexual reproduction as a backup for asexual cell division, so they will keep spreading across the host.
Answer:
b.) diffusion
Explanation:
Gas exchange is occur through the diffusion across the surface.
Diffusion:
It is a process in which gas exchange is occur through the concentration gradient. Gas molecules are moves from region of high concentration to the region of lower concentration.
Example:
In blood the concentration of oxygen is low and carbon dioxide is high while the air in lungs is high in oxygen concentration and low in carbon dioxide concentration. This concentration gradient leads to the exchange of gases in respiration. During respiration oxygen gas is intake while carbon dioxide is released.
