smelled by our noses. These microorganisms’
causes illnesses, especially to their host, the host serves as their food,
shelter and victim. Pathogens are found in wastes, such as hospital wastes or
in the sewages. Pathogens are mostly parasites, which is why they need a host
to survive.
Answer:
25 and 21
Explanation:
if a homologous pair does not separate, then the homologous pair (when the spindle fibers are dragging it over to the other pole), then that chromosomes DNA will be the exact same as the paternal and maternals' DNA. During Meiosis I, there is the stage where the homologous pairs are lined up and pulled apart (where an exchange tends to happen), but if there pair doesn't mix, then the exact same DNA is duplicated, and thus, the same traits can be found in the daughter cell. If you are talking about an entire homologous pair being pulled over to one side of the nucleus, depriving the other side of a chromosomal pair, the daughter cells would then have 21 chromosomes, and the other one would have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.
Answer:
The correct answer is option A. "A statin".
Explanation:
Statins a type of drug that are prescribed to treat people that are at high risk of developing a cardiovascular disease. Since Joanne is a person with history of coronary artery disease and her LDL levels remained high after trying diet changes, the next step in her treatment will be to take a statin drug. It has been proved that statin are among the most effective drug at lowering LDL levels, therefore, a treatment with a statin will be effective for Joanne's condition.
Since chemical spills are very harmful to aquatic/land life for both plants and animals, plants probably wouldn't grow back and animals could be mutated or even killed, decreasing the population of that species. A volcano eruption, can be both good and bad, since a volcano can kill animals and plants, but ash from a volcano is extremely fertile, so plants can regrow, which in turn brings animals back so they can feed on those plants.
