Answer:
Rhizobium is a genus of bacteria associated with the formation of root nodules on plants. These bacteria live in symbiosis with legumes.
Explanation:
If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).
<h3>Define double helix model of DNA?</h3>
- DNA is a double helix molecule made up of two long strands of nucleotides.
- There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
- Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
- As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
- Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%

According to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.
<h3>What is the hepatic portal vein?</h3>
It is a blood vessel that carries deoxygenated blood from the digestive organs and the spleen to the liver.
The linear vein is one of the branches of the celiac trunk that supplies the spleen and gives off branches to the stomach and pancreas.
Therefore, we can conclude that according to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.

The baglike structure that contains a clear fluid in which the developing embryo floats is called the Amnion.
<h3>
What is an Amnion?</h3>
The membrane that covers the embryos of reptiles, birds, and the mammals when first formed is called Amnion.
It contains amniotic fluid, which serves as an amniotic sac that provides a protective shield for the developing embryo. Together with the amnion, contains the
- chorion
- the yolk sac
- allantois
with different functions to protect the embryo.
The amniotic sac in humans is enclosed in the uterus while for birds, reptiles ,it is enclosed in a shell.
