1. Standard 7.L.1.1-Tina observed a cell under a microscope. She concluded that it was more than likely a plant cell instead of an animal cell. Which structure helped her come to this conclusion? * a. She saw a vacuole.

b. She saw a nucleus.

c. She saw a chloroplast.

d. She saw a cell membrane.

A

Explanation:

Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

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.
