Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
The cuticle is the most exterior layer of arthropods' tegument, and its principal function is to protect the body and avoid dehydration. Option C is correct. Cuticle.

What is the cuticle?</h3>
The cuticle is the most exterior layer of arthropods' tegument. It is secreted by the epidermis and develops right over it.
It is composed of two main layers,
- epicuticle ⇒ outermost layer
The cuticle is mainly made of chitin, and its function is to protect the organism's body and avoid dehydration.
Because it avoids dehydration it is believed that arthropods had such an evolutive and adaptative successful in their transition from water to the land.
The cuticle also provides support to the body and a muscle attachment surface.
The correct option is C. Cuticle
A _<u>Cuticle</u>_ is a hard outside covering that is used for protection and prevents the inner body area from drying out.

Answer: Does the organism perform photosynthesis?
Explanation:
Answer: See explanation.
Explanation: It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
Answer:
all of the above can lead to increase in nitrogen
