Chapter 29, Problem 1MCQ
Summary Introduction

Introduction :

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.

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.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
