The accurate statements to the signal transduction pathways are as follows:
1. A receptor changes conformation upon attachment, conducting a signal across the cell membrane.
2. A second messenger may carry a signal from the cell membrane to an organelle.
3. Signal transduction cascades, often involving protein kinases, amplify a signal intracellularly.
4. A receptor may pass on a signal by associating with another protein or by functioning as an enzyme.
5. A ligand, like hormone, combines with a specific cell surface receptor on a target cell.
6. Phosphatase eradicate phosphoryl groups from polypeptides, monitoring the response of the cell.
Answer: All of the choices are correct.
Explanation:
Schamberg's disease is the pathological condition that allows lymph to leak from the blood capillaries, it causes no other symptoms beside skin discoloration and itching. The condition is caused by inflammation of capillaries near the surface of skin and subsequent leaking of blood cells into surrounding tissues.
So, the Lymph found in this patholgical condition is a fluid that circulates the entire body in the lymphatic system. The lymphoid organs include (the spleen, lymph nodes, bone marrow, thymus and lymph tissue) . These lymph nodes are small, bean-shaped structures which produce and store cells, specialized in fighting infections.
In the spleen (an organ in the upper left abdomen, filtration of these blood and disposal of worn-out blood cells occurs ), Hence, provides a reserve supply of blood.
However, Fluid in the spaces between the tissues are called interstitial fluid (tissue fluid). They provides the cells of the body with nutrients (via the blood supply) and a means of waste removal.
As such, Lymph is formed when the interstitial fluid is collected through tiny lymph capillaries, which are located throughout the body. It is then transported through lymph vessels to lymph nodes, which clean and filter it. Lymph then flows on to the lymphatic ducts, before emptying into the right or the left subclavian vein, where it mixes back with blood.
Answer:
Sparse coding
Explanation:
Sparse coding can be described or explained as a situation where items are encoded or represented by strong activation of a relatively small sets of neurons.
It should be understood that neurons code for the intensity of stimulus , and this is done in two ways which are
* Frequency coding...here, the firing rate of sensory neurons increases with increased intensity, and
* Population coding....here, the number of primary afferent responding increases.
In this case, the results derived or gotten from both Arthur's and Roger's faces supported the sparse coding.
Should be Eukarya, I think
The answer for this question would be choice <span>B) Water, rock, and surface materials, or the second option.</span>
