2 ways in which cross pollination is occurred

Biology
1 answer:

  1. By insects: When a bee, butterfly, etc. try to get the sticky sweet pollen inside a flower, the pollen catches on to the insect, too. Then when the insect goes to the next flower, the pollen in pollinates. Note that this is <em>not</em> on purpose.

    2.  Another way plants are pollinated is by the wind. The wind picks up pollen from one plant and blows it onto another. Note that this is by nature.


I hope that helps! :)

mRNA

Explanation:

poly-deoxythymidine (poly-dT) beads binds to polyadenylated (poly (A) molecules with high affinity because Thymidine base pairs with the Adenine of the poly(A) chain.

Since messenger RNA (mRNA) is polyadenylated after transcription in contrast to other RNA species, this method is more suitable for mRNA purification.

What system delivers oxygen and nutrients to every cell in the body
Blababa [14]

Answer:

The Circulatory or Cardiovascular System

Explanation:

This system allows the circulation of blood to every cells of the body with the transport of oxygen and nutrients essential for its survival. These nutrients include glucose, amino acids, vitamins, minerals and so on produced by the body through metabolism.

The circulatory system comprises also of the lymphatic system, which allows for the flow of lymphs.

The circulatory system is made up of systemic and pulmonary circulation. The heart and blood vessels being the major structures in this circulation. The blood moves to the lungs and get oxygenated (pulmonary circulation) and it then returned back to the heart for transport to other parts of the body known as the systemic circulation. Hemoglobin, which carries oxygen in the blood and also carbon iv oxide for excretion out of the plasma. From the digestive system, the nutrients are absorbed into the blood plasma and then transported for the cell use or for storage.
