c) establishing public empathy for charismatic species provides an opportunity to educate people about lesser-known species.
d) the public tends to value intact ecosystems over particular plant and animal species.

The correct option is C. Establishing public empathy for charismatic species provides an opportunity to educate people about lesser-known species.

Explanation:

Through the Endangered Species Act (ESA), the public will get to know about the species which are at the verge of being extinct and they once contributed to be a part of an ecosystem. The public will be entitled to show empathy for organisms that are endangered if proper info is conveyed to people about these animals. The people will try their best to help and conserve these species. This will result in conserving the biological diversity.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
