The bony landmark that <span>can be felt and seen, and is commonly used to help determine where to give an intramuscular injection on the lateral surface of the thigh is called <u>the greater trochanter.
</u><u />The illiac crest is found on the pelvis, the lateral epicondyle is in the arm, and the remaining options are too small to be felt and seen. So the correct answer has to be the greater trochanter found on the femur, or the thigh bone.<u>

Question:
A---enzyme A------>B----enzyme B------>C
Refer to the metabolic pathway illustrated above. If A, B, and C are all required for growth, a strain that is mutant for the gene-encoding enzyme A would be able to grow on medium supplemented with _____.
A) nutrient A only
B) nutrient B only
C) nutrient C only
D) nutrients A and C
Answer:
B) nutrient B only
Explanation:
The mutant has a mutation in the gene that codes for the enzyme A. Therefore, this mutant would not be able to convert the substance A into B. Without the presence of substance B, the final product can not be formed. However, if the mutant is supplemented with the substrate "B", it can convert the B into the final product (substance C). Therefore, the mutant would be able to grow in the medium to which the already prepared substance B has been added.
Answer:
Hypersensitivity is also known as intolerance which is defines as an unwanted reactions due to changes or interference with immune system for example allergies and autoimmunity. Hypersensitivity is the reaction of immune system that can be harmful and weakens once body.
Allergy is kind of hypersensitive reaction which is having fast response within few minutes rather than hours or days. In the case of allergies free antigens cross link with IgE on mast cells and basophils and releases vasoactive biomolecules. Few example of Allergies are anaphylaxis and asthma.
Autoimmune disorders are also a kind of hypersensitive reaction which occurs when body's immune system attacks own body cells mistakenly. few examples are Type 1 diabetes, Rheumatoid arthritis (RA), and Multiple sclerosis.
Carbon moves from the atmosphere to the biosphere and also from the atmosphere to the hydrosphere through a variety of processes.
<h3>Carbon cycle</h3>
Carbon in the form of carbon dioxide in the atmosphere is sequestrated by plants (biosphere) through a process known as photosynthesis.
When plants die, their organic matter decomposes into the soil (lithosphere) while some carbon is released back into the atmosphere via decomposition. Soil carbon also helps plants to grow.
Carbon in the atmosphere also gets sequestrated into water bodies (hydrosphere) by dissolution.
