It would be epithelial tissue that covers it.
Answer:
Benthic Zone- bottom of ocean
Pelagic Zone- the open ocean that is not near the coast.
Oceanic zone- Zone that is beyond the continental shelf
Neritic zone- Zone that exists over the continental shelf
Photic zone- Zone where sunlight pass through
Aphotic zone- Zone where sunlight cannot pass through
Explanation:
There two important zones of the ocean that can be termed as Benthic Zone which lies at bottom of ocean or sea and Pelagic Zone that could be imagined as a cylinder or water column that goes from the surface of the sea or ocean to its bottom. At the very bottom of the sea there lies an ecological region termed as Benthic Zone.The pelagic zone can also be termed as the open-ocean zone and it is in contrast with water that is nearer to the coast or continental shelf.
There are different zones that lies within a Pelagic Zone. They are
Oceanic, Neritic, Photic, Aphotic. The zone that lies beyond the continental shelf comes under this oceanic zone and Photic and Aphotic as the name suggests it refers to light. It referes to the zones where sunlight can penetrate and can not penetrate respectively.
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>
Answer:
This event is telling the evolution by natural selection. This is the directional selection where most adapted animals will survive. According to Darwin, the new species arise from a single ancestor due to variation.
It had also seen in the Finches. All the new species of Finches came from a pre-existing seed-eating Finch. When the environment was favorable the Finches were herbivore and feed on seeds.
When the number of birds increases, there is a competition between them. Because the food source was limited. To prevent this competition
some of them go for different foods like insects, fruits, etc.
This food habit change also changes their morphology and separate them from their ancestor.
Similar manner, when draught condition occurs, some of the seed-eating birds become carnivore to survive this new climate. As the environmental condition continues for a long time, the number of carnivore animals will increase in number.
Because due to drought conditions, the availability of seed will decrease. Thus the carnivore birds will be more in number and the herbivore birds will gradually eliminate, as they can't cope with the new climate.
If most of my cooking equipment is copper and my utensils are silver, I will not want to use a sanitizer that contain CHLORINE. This is because, chlorine in the sanitizer will react with the silver of the utensils to form a black layer of silver chloride on the utensils. Also, chlorine will react with the copper of the cooking equipment to form a cloud of copper ll chloride which will dissolve when it comes in contact with water forming a blue green solution.<span />
