Which of the statements concerning blood collection in mice and rats is true?

Biology
1 answer:
Sindrei [870]3 years ago
8 0
The correct option is this: POTENTIALLY LESS PAINFUL ALTERNATIVES TO RETROORBITAL BLOOD COLLECTION INCLUDE LATERAL SAPHENOUS AND JUGULAR VEIN BLOOD COLLECTION.
Rats are very important in research work and they are often used to test the effects of various substances in the body. To do this, blood has to be collected from the rats and this can be done in various ways. But some methods of blood collection is more painful than the others. Collecting blood from the  retro orbital vein is less painful compared to other methods.<span />

Tcecarenko [31]

Among the typical midlife changes for men is an Increase in prostate size.

A portion of the fluid that carries sperm during ejaculation is produced by the prostate, a gland. The urethra, which is the tube through which urine leaves the body, is surrounded by the prostate gland.

As you get older, your chances of having an enlarged prostate go up. Because BPH is so common, it has been said that if a man lives long enough, he will all have an enlarged prostate. Many men over 40 have a small amount of prostate enlargement. The condition affects more than 90% of men over the age of 80.

Which processes are involved in the chloroplast of a plant cell?
Ahat [919]

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.

Why do antibodies allow scientists to target and identify specific disease agents?
masha68 [24]
Antibodies bind to the antigens on the surface of disease agents. If some sort of fluorescent tag is added to the antibody it would make the disease agent be identifiable either under a microscope or with other Instruments because it would bind to the antigens on the surface of the disease agents and make them glow a certain color. I hope that this is the answer that you were looking for and it has helped you.
