When the tetrads are formed

Biology
1 answer:
Rudiy273 years ago
8 0

Answer:

B. The chromosomes exchange genetic information.

Explanation:

Crossing over of tetrads during meiosis is very important for the exchange of genetic information.

This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.

Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.

So, the correct answer is B. The chromosomes exchange genetic information.

A client in cardiovascular collapse requires pharmacological interventions. what route of administration is most likely appropri
sdas [7]

Intravenous

When a client in cardiovascular collapse requires pharmacological interventions intravenous administration is most likely appropriate.

<h3>What is meant by intravenous administration?</h3>
  • Some drugs need to be administered intravenously (IV), either as an injection or an infusion.
  • This indicates that a needle or tube is used to deliver them directly to your vein.
  • A small plastic tube called an IV catheter is placed into your vein during IV administration; in fact, the word "intravenous" literally means "into the vein."

<h3>Where are injections given intravenously?</h3>
  • A needle is often inserted during normal IV administration into a vein in the wrist, elbow, or back of the hand.
  • After that, the catheter is put over the needle.
  • The catheter stays in your vein after the needle is taken out.
  • In a hospital or clinic, all IV catheters are routinely administered.
  • This enables the medication or fluid to immediately reach your bloodstream.
