2. As a result of your initial efforts you were able to detect the presence of protein K using IgG. However, when your lab mate

repeated your work after heating protein K they were unable to detect the presence of protein K using IgG. Explain why your lab mate was unable to detect the presence of protein K with IgG even though you demonstrated that it was possible

Answer:

Protein K is a protein that can available in the human cell nucleus that binds to pre-messenger RNA as a part of heterogenous ribonucleoprotein. IgG is one of the five isotypes of immunoglobulin or antibodies.it is the most common antibodies in the blood circulation and makes the 75% of total antibody.

When you heat solution, generally protein k activity increase with an increase in the heat but up to an extent or point called optimum temp. The optimal temperature for activity ranges between 50-65°c. When an increase in temperature help with protein unfolding easing the ability for protein k to break down those proteins.

almond37 [142]

Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?

a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.

b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.

c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.

d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.

Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>

Explanation:

By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.

Juan has been diagnosed with mono, and the doctor wants to determine if his spleen is enlarged. Where (quadrant, etc.) will the
hichkok12 [17]

Answer and Explanation:

  • Where (quadrant, etc.) will the doctor palpate Juan's abdomen?

<em>Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).</em>

  • What other organs might be compressed by Juan's enlarged spleen?

<em>The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed. </em>

  • why is Juan's spleen enlarged and not his stomach or kidney?

<em>The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.</em>

The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.
