Why is it necessary to match the donor's and the recipients blood before a transfusion is given

It is necessary to match the donor's and the recipient's blood before a transfusion because the immune system will react badly if blood cells are not compatible. The immune system is responsible for patrolling or for guarding the circulation in the body. Without its proper function, the body will be exposed into different types of infections.

When blood goes through the process of transfusion, the cells are treated the same way as infections or foreign invaders. When they are not compatible with the recipient the immune system will be massively activated which can cause immediate clotting systems in the blood. The results of this clotting can lead to shock, kidney failure, collapse of the circulatory system, and worst death.

If you measure the rate of respiration of plant root hair cells, would you expect it to be the same as, more than, or less than

DaniilM [7]

Answer:

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.Plant respiration occurs 24 hours per day, but night respiration is more evident since the photosynthesis process ceases. During the night, it is very important that the temperature is cooler than during the day because plants can experience stress. Imagine a runner in a marathon.

roots respire too!

One of the functions of the substrate is to serve as a site for air exchange between the root zone and atmosphere. In other words, roots breathe oxygen like we do. Different plants have different oxygen requirements for their root systems.

For example,

the root system of a poinsettia requires a lot of oxygen, so it is best to use a substrate with high air porosity, while hostas can live well in a substrate with a high water holding capacity.

kozerog [31]

Answer:

Chromatin

Explanation:

The unwound, filamented mass of DNA and associated proteins in a cell that is not dividing id termed as 'chromatin'. The major function of the chromatin is to pack the DNA into the compacted dense shape so that any type of tangling is avoided in the DNA strands. The chromatin is known to be present in every eukaryotic cell. It is due to chromatin that the chromosomes are properly segregated during the anaphase. The nucleus is the site where chromatin is present.
