Answer:
c. creates a high osmotic pressure in the medulla
Explanation:
Loop of henle is a nephron the runs from proximal to distal convulated tubule. It create in the medulla an area of high urea concentration using energy to create the concentration gradients. Henle of loop is divided into four compartment.
1. thin ascending limb of loop of henle- it is highly permeable to water
2. thin decending limb of loop of henle is not permeable to water but Ion
3. ascending limb of loop- reabsorbtion of calcium, sodium and potassium ion from urine takes place here
4.Cortical thick ascending limb- It drains urine into distal convulated tubule.
Explanation:
As tectonic plates drift due to the convection currents of the mantle below, so does the climate on the tectonic plates. This is because the drift causes the continents to glide across latitudes. Different latitudes have different climatic conditions associated with them. An example is an equatorial climate in the equator, the subtropical climate in the mid-latitudes and polar climate in the polar region.
Therefore, even though this drift is happening very slowly over millions of years, the plant and animal species in these continental also slowly adapt to the changing climatic condition in their environment associated with these continental drifts.
The keratinocytes approximately 90% of cells.
There are three physical types of media, theses are solid, liquid and semi-solid.
In liquid media, growth occur throughout the media. In solid media, there are firm surfaces for bacteria to form discreet colonies. This type of media usually contain 1-5% agar. For semi-solid media, this type of media has soft constituency at room temperature and does not flow freely.
