(4) is bred and the trait is capable of being inherited
Explanation:
<u>Mutation generally refers to a sudden change to the DNA sequence in the genome of an organism.</u>
Since, DNA is the molecules responsible for heredity and the inheritance of traits by offspring from their parents, a mutation should be inheritable.
<em>Hence, if a sudden appearance of hairlessness in one of the puppies is observed by a dog breeder, he/she can effectively conclude that the situation is caused by a mutation if the affected dog is bred with another dog and the hairlessness is observed in any of the resulting progeny.</em>
Option 4 is the correct option.
Answer: 1. Protostome development./2. Bilateral symmetry/4. Three embryonic germ layers
Explanation:
Over 600 million years ago some animals invaded aquatic and terrestrial environments in the pre-Cambrian period. These animals were enforced by huge evolutionary irradiation, and now they occupy every environment on planet Earth. From tiny insects and crustaceans smaller than 1mm in length to giant crabs from Japan that can reach 3m (with open legs), the arthropods are found in all size models, with an estimated number of more than one million species described. Concerning characteristics they are - Bilateral, triploblastic( Three embryonic germ layers), prostomial.
