How is the inside surface area maximized in each animal dogfish shark?
Alexus [3.1K]
The inside surface area is shaped in a crescent. It consists of a spiral valve which is made up of the small intestine. Although the dogfish shark has a relatively short small intestine compared to other animals, therefore, the spiral valve allows for a more compact form of the small intestine.
Hence, this structure provides maximum surface area over a relatively short distance in order to make the absorption of nutrients efficient achieved from the food, the sharks had from eating different sea animals.

Increased Serum Interleukin-2 Levels Are Associated with Abnormal Peripheral Blood Natural Killer Cell Levels in Patients with A
amm1812

In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.

Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.

The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.

This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).

The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells

svet-max [94.6K]

Answer:

<em>B and C.</em>

Explanation:

The epidemiological triangle is an illustration of interaction among suitable hosts, disease agents, and the environment that drives successful outbreak of diseases.

In order to successfully tackle or reduce the incidence of a disease, the triangle has to be broken.

<em>In the case of malaria which is caused by plasmodium but spread through the female anopheles mosquito, one way of breaking the epidemiological triangle is to eliminate female anopheles mosquito in the environment using any possible means. This will stop the spread of the parasite and hence, the disease.</em>

<em>Another way to reduce/prevent malaria is to prevent the vector, female anopheles mosquito from getting to the host, the human populace. This can also be achieved by several possible means.</em>

Relocating the entire village to a neighbouring village might not break the epidemiological triangle as long as female anopheles mosquito still abounds. In the same vein, antibacterial drugs will not help to treat malaria. However, instructing residents on personal protective measures and controlling the vector through chemical larvicides will go a long way in breaking the triangle and reducing the incidence on the malaria disease.

<em>The correct options is B and C.</em>
