A mutation is a change in trait. For example people who are lactose intolerant are normal, but people that can can drink milk without a problem have mutated. Hopefully this makes sense and helped.
Answer:
The correct answer is C: l<em>oss of chloroplasts.</em>
Explanation:
The parasite would lose chloroplasts. As they absorb nutrients from the fish digest food in the gut of the animal, parasites do not need to photosynthesize any more. There are some parasites in the fishes digestive tract that conserve their motile capacity by keeping their flagellum or cilium. Some species get their membranes thicker for protection in their interaction with the host, and they can also secrete a special capsule. In general, these organisms reproduce asexually.
Answer:
the correct answers are as follows
12:
b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.
13.
e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.
14.
c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.

e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
