name the main nitrogen-containing compound found both in plants and in animals​

Answers

Answer:

Soil contains nitrifying bacteria that are crucial in converting nitrogenous wastes of dead and decaying matter of plants and animals to ammonia.

The most redox potential of soil nitrogen, ammonia, is transformed into its most oxidized form, nitrate, by nitrifying bacteria. By preventing soil nitrogen losses from leaching and nitrate denitrification, this is crucial for the function of the soil ecosystem.

What nitrogen compound found in plants and animals​?

The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals. The ammonia is subsequently changed into compounds that include ammonium. This is how the formation of ammonium compounds is aided by animals and plants.

Nitrification, which turns ammonia into nitrite and then nitrate, is a vital stage in the worldwide nitrogen cycle. Only prokaryotes perform aerobic nitrification, which makes up the majority of the process.

Therefore, The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals.

Answers

I’m pretty sure it’s a 50% chance since the colorblind mother has two kids and one of them has the trait.

25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

What is Colourblindness?

Color blindness is defined as a reduced ability to differentiate between colors compared to the norm of normal human color vision. It is also called color vision deficiency (CVD) when a person is color blind, usually having difficulty distinguishing between certain colors such as yellow and orange, green and brown, pink and grey, or blue and green. Purple. These are typical of what is called "red-green color blindness".

The genes that can give red-green color blindness are passed on the X chromosome, although it is passed on the X chromosome, red-green color blindness is more common in males, causing males to inherit it from their mothers. There is only 1 X chromosome.

In the above case, if the mother is not colour blind but her son is color blind so, the probability for her daughter is 25%.

Thus, 25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

Answer:

Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.

H20 is a molecule, N2 is a molecule even O3 is a molecule.
