1. A future offspring has just been conceived. When does it have the highest level of potency?

Brums [2.3K]

Answer:

When a future offspring has just been conceived it has the highest level of potency in Totipotency.

Explanation:

Potency is the ability of cells to differentiate. AT different stages of development the level of potency changes. The highest level of potency is Totipotency and these cells have the ability to develop a whole organism. The common examples are spores and zygote. In embryonic stage the cells are Pluripotent and they can differentiate into different type of cells. Pluripotent cells after further development changes into Multipotent cells. Unipotent cells have the least potency and can develop only in one cell linage.

In which of the following environments would you NOT expect to find fossils? (2 points)

Zepler [3.9K]

You would generally not be able to recover fossils from volcanic or plutonic rock, so looking around in an area on active volcanic islands would yield nothing.

You always want to look in the layers of sedimentary rock for fossils. The Grand Canyon would be a great place to see these layers as well as a shallow ocean because you may find the remains of prehistoric shark teeth or bones protruding through the surface of the sand.

The answer is Active volcanic islands.

If this is a question in which you can choose more than one answer it may be smart to also choose a shallow ocean as well. This is because it is difficult to get the tools and materials necessary down in the water and would be difficult to get deep enough underneath sand to start digging into actual fossil bearing rock.

So in that case, the answer would then be both Active volcanic islands and A shallow ocean.

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Ymorist [56]

The following vessels are connected as below:

aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.

1) aorta : arises from heart which carry blood from heart to the rest of the body

2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .

3)segmental arteries : it arises from renal artery .it has 5 branches or segments.

4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.

5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.

6) cortical radiata: it arises from arcuate arteries.

7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.

8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.
