The majority of animals have an exoskeleton, a tough exterior covering that shields them from the elements. The animal is supported by the endoskeleton, which is located inside the body. The majority of the exoskeleton is composed of bone and cartilage. The exoskeleton is made up of shells made of chitin, cuticles, and scales.

The majority of animals have an exoskeleton, a tough exterior covering that shields them from the elements. The animal is supported by the endoskeleton, which is located inside the body. The majority of the exoskeleton is composed of bone and cartilage. The exoskeleton is made up of shells made of chitin, cuticles, and scales.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer :

The correct answer is option (a) their ability to protect an animal from the outside.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) their ability to protect an animal from the outside. The organism's exoskeleton is its outside, hard shell. The animal is therefore shielded from the environment by its exoskeleton. On the other hand, the endoskeleton supports the body from within. So, the correct answer is option (a).

Explanation for incorrect answer :

Option (b) their ability to grow along with an organism. Exoskeleton-equipped animals molt or lose their outer skeletons as they grow in order to produce new ones. This aids the animal's ability to enlarge and change in form while preserving its exoskeleton. Given that an endoskeleton exists inside the body, it expands as the body does as it becomes larger and more voluminous. Because of this, the exoskeleton does not develop with the organism, but the endoskeleton does. So, this is an incorrect option.

Option (c) their function as a framework for muscle attachment. Both the exoskeleton and the endoskeleton offer surfaces on which the organism's numerous muscles can be attached. Therefore, the exoskeleton and endoskeleton are identical in this regard. So, this is an incorrect answer.

Option (d) Both a and b are correct. The solution given in option (b) above is incorrect. As a result, the responses listed in option (d) cannot be combined.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
