Answer:
Storage proteins serve as biological reserves of metal ions and amino acids, used by organisms. They are found in plant seeds, egg whites, and milk. Ferritin is an example of a storage protein that stores iron. Iron is a component of heme, which is contained in the transport protein, hemoglobin and in cytochromes.

<u>Answer :-</u> <em>Option 2</em> 90 mm is correct.
<u>Explanation :-</u>
- In the given diagram, we consider the starting point of measurement the value where the mouth of the earthworm is pointed i.e 1.5 cm.
- So if we count from 1.5 cm that is the start point and then we see the end point i.e 10.5 cm we get,
10.5 - 1.5 = 9.0 cm
So the length of the earthworm is 9.0 cm as seen from the scale.
- Now to convert cm into mm, we need to know that:
1 cm = 10 mm
Thus, to convert 9.0 cm to mm
we need to multiply 9 by 10
9 X 10 = 90
So the answer is 90 mm.
The air that we breathe is mostly made up of nitrogen (78%). 21% is oxygen which is needed for animals and humans in respiration and 0.03% is carbon dioxide which is needed for plants to make energy in a process called photosynthesis. The bit that is left is made up of rare gases like helium and argon and methane.
The answer is <span> a strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus.
Electromagnetic forces are the cause why like charges repel and vice versa, why unlike charges attract. For an atom's protons to hold together and not to fly apart, there must be a force that is stronger than the electromagnetic force. Therefore, the </span><span>strong nuclear force between an atom’s protons and neutrons holds together the atom’s nucleus. </span>
Answer:
Cell Membrane
Explanation:
The unique structure of the cell membrane allows small substances (like oxygen or carbon dioxide) to easily pass through.
