<h2>Availability of Plankton</h2>
Explanation:
- The term plankton comes from the Greek derivative planktos, meaning wandering. Organisms in this group spend either part or all of their life in a drifting state, with no ability to swim against a current. Most have little or no ability to swim at all. Though some are larger, most planktonic creatures are microscopic and make up the bottom of the food chain in aquatic environments
- Plankton can be divided into two categories: phytoplankton are those organisms that are plant-like, and zooplankton are organisms that are animal-like. Interestingly enough, many planktonic species are neither plant nor animal but are creatures that belong to the kingdom Protista
- Zebra muscles are found in water bodies which attached to pipes and other surfaces of water supply to impliment the availability of plankton

Phosphorus can be found in foods (organic phosphorus) and is naturally found in protein-rich foods such as meats, poultry, fish, nuts, beans and dairy products.
The answer is B)<span> </span>temporal isolation.

<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>
Answer: A federally funded research study involving children 8 to 12 years old involves collecting a single voided urine sample to assess the frequency of asymptomatic <em>proteinuria</em>.
Your IRB has determined that assent of children age 8 and older is required for the study. A 10 year old firmly declined to participate in the study.
The best procedure that describes the <u>action </u>to be taken by the investigator is:
- Honor the Childs decision .
Explanation:
The <em>purpose</em> of the IRB is to <em>assure that appropriate steps are taken</em> to <em>protect the rights </em>and welfare of humans participating as subjects in a research study. It promotes <em>fully informed and voluntary participation</em> by prospective subjects capable of making such choices (or, if that is not possible, informed permission given by a suitable proxy), and seeks to maximize the safety of subjects.
The capacity admits degrees. The same patient may be able to decide certain things and not others. So, the more transcendent or delicate a decision is, the higher the level of capacity required must be. When the patient <u>is not capable, it is up to his relatives to make the decisions.</u>
