(number 16)what structure is responsible for the cell structure stability?

The answer is the number 2. Why? Because the cytoplasm is a fluid that sustains the cell shape. The mitochondria is a organelle, ribosomes are protiens and vacuoles are carriers/storage bins.

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.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
