Explain how the structure of the capillary wall helps to allow the plasma out of the blood

1 answer:

8 0

The capillary wall is super thin, and its structure allows for substances to easily diffuse. As a result, it is also highly permeable to water and all plasma solutes, except for plasma proteins. It is the capillary wall's transport-type of thin structure, because it is highly permeable. And that allows plasma out of the blood

Cells must use energy to move a substance against a concentration gradient i.e., from a compartment with a low concentration of

garik1379 [7]

Answer:

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Explanation:

In general the concentration of sodium ion is higher outside the cell in the extracellular fluid and the concentration of potassium ion is higher inside the cell.

During an active transport, a cell uses energy to move molecules against the gradient as a part of primary active transport. In the secondary active transport, the molecules move as per the electrochemical gradient established by the primary active transport.

In primary active transport, sodium ion moves out of the cell and potassium ion moves into the cell through the assistance of sodium potassium pump. In order to maintain the stability, calcium ion from the sarcoplasmic reticulum is pumped out of the cell

Hence , the correct answers are

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

How to get high affinity antibody?

Anit [1.1K]

Human monoclonal antibody (mAbs) are emerging in the field of cancer therapy and have become an increasing proportion of new drugs that are recently approved. Although there are some methods to obtain antigen-specific mAbs from human B cells, it is generally impossible to directly immunize human beings with antigens of interest. For example, for infectious agents, those approaches are largely restricted. To solve these obstacles, two main approaches have been developed; either by humanizing antigen-specific antibodies from small experimental animals (which is laborious due to the great genetic differences from humans) or rely on the in vitro selection of antigen-specific binders from human antibody repertoires. However, the human mAbs developed by these methods are usually with low affinity.

We are now coming up with a much better idea that is humanizing non-human primates mAbs instead of murine mAbs. Due to the close genetic relationship with humans, immunized NHPs have more potential to be isolated with high affinity antibody to human target than other experimental species, such as mouse, rat and rabbit. In addition, with appropriate method, NHP antibodies are much<span> easier to be humanized</span> without any loss of affinity compared to widely used murine antibodies.

Name one benefit and one limitation of comparative

Anon25 [30]

Answer:

Limitation of comparative is that when it is done on a huge population, huge amount cost is required.

Benefit of comparative is that we can get descrete information about specific breed or species.

What are genetically modified foods?

V125BC [204]

Answer:

genectically modifed foods are also known as gentically engineered foods , or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits when compared to previous methods, such as selective breeding and mutation breeding.[1]
