Many insects have a tough outer shell called _____. an exoskeleton cellulose an endoskeleton chitin

Answers

Answer 1
Answer:

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.'

 

Answer 2
Answer: The correct answer is an exoskeleton

Fish, poultry, lean meats, and nuts should be consumed for which of the following nutrients?

A. calcium

B. carbohydrates

C. protein

D. vitamin D

Answer: C. Protein

Answer: Fish, poultry, lean meats, and nuts should be consumed protein.  

Explanation:

Fish, poultry, lean meats, are seafood and they are highly rich in protein with a very low amount of fat. The ratio of fat and protein is about 5 grams in a 3-ounce serving and it consists of omega 3 fatty acid. Cashews, Pistachios, Almonds are the nuts rich in proteins approximately 8-18% protein.

Use the models that you created in Lesson 2, Lab 1 to help you answer the following question. Compare the surface area to volume ratio of a large cell to that of a small cell.

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

Answers

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.

B. A smaller cell has more surface area than volume. This allows for more reactions to occur across the various membranes of the cell.

Which of these is not a function of your skin?

Answers

Since there's no choices attached on your questions on which of these is not a function of your skin. I'll give you one.
- Holds the bone of the skeletal system is not the function of the skin. Skin only protects.

Final answer:

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.

Explanation:

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.
