Answer:

D) begins as a cell, comes from an organ, is part of a system

Explanation:

Here is how pollen is formed, in simpler words, it comes from sporogenic tissue, formed inside the male organ called the anther, and is part of the male reproductive system.

The formation of a pollen grain begins inside the male part of a flower called the anther, within specific tissue called sporogenic tissue. Here, the developing pollen receives nutrition and a coat of cellulose, which is a very strong plant protein. First, large pollen mother cells are produced, which eventually break into individual pollen grains through cell division. At this point, the pollen grain gets its outer coat, called the exine, which is made from another tough plant protein. The exine protects the delicate genetic material inside the pollen grain from water loss, and damage caused by UV radiation and other environmental causes. In some plants, the pollen grain also gets a sticky outer layer to help it adhere to the female part of another plant, called the stigma. The final step involves another cell division, which creates two cells within one pollen grain. After that, the pollen grains move to a drying-out phase, after which they take on their dusty appearance and are ready to go out into the world and fertilize ovules.

What would you expect to happen if a transfusion recipient had blood type o and a donor had blood type ab?
NNADVOKAT [17]

If a person with blood group type O received blood transfusion from type Ab it will lead to major hemolytic transfusion reaction.  

<h3>What is Blood Transfusion?</h3>

Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components. The blood's components, such as red blood cells, white blood cells, plasma, clotting factors, and platelets, are now frequently used in transfusions instead of the whole blood that was used in earlier times.

Hemoglobin is a component of red blood cells (RBC), which carry oxygen to the body's cells. Although they are not frequently utilized in transfusions, white blood cells are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood called plasma serves as a lubricant and is made up of essential nutrients and proteins for the body's overall health.
