Answer:
An exoskeleton.
Explanation:
Tough outer shell of many insects is known as exoskeleton that represents an external skeleton. The exoskeleton provides protection and support to the insects body as they lack an internal skeletal system as higher organisms. In insects, it is made up of chitin.
Exoskeleton also plays role in sensing, feeding, excretion, and protection against desiccation in land insects.
Thus, the correct word to be filled in the blank is 'exoskeleton.'

Why does the ratio of surface area to volume increase with the decrease in cell size?
A. A larger cell has more surface area than volume.
B. A smaller cell has more surface area than volume.
C. A smaller cell has more volume than surface area.
D. A smaller cell has an equal ratio of surface area to volume
Answer:
B
Explanation:
This is a question more about understanding ratios than understanding cells.
A surface area to volume ratio (S/V) in a size-decreasing cell would increase due to a more significant loss in volume that in surface area. In reality, both decrease (surface area AND volume), but as we are talking about a ratio, this one would go up due to a more dramatic decrease in volume.

The skin performs many functions including protection, regulation of body temperature and sensation of surroundings. However, it does not produce blood cells, which is a function performed by the bone marrow.
The skin, also known as the integumentary system, performs a number of essential functions that help maintain our health and wellbeing. These include protecting our bodies from external hazards, regulating body temperature, and allowing us to sense our surroundings. However, one function your skin does not perform is the production of blood cells. This is the role of the bone marrow, a soft tissue inside your bones. Thus, production of blood cells is not a function of the skin.
