One of the symptoms of high salt concentrations in soil is plants that appear dehydrated even when they are receiving adequate water. How can you
explain this phenomena using what you observed in the root cells of the salt-
sensitive plants?

The negative impacts of nonnative species generally outweigh the positive impacts

In a lab, scientists grew several generations of offspring of a plant using the method shown. what conclusion can you make about the offspring? a. they formed from meiosis and mitosis. b. they have half the number of chromosomes as their parent. c. they have low genetic variability among them. d. they will be able to reproduce only after they grow flowers.

In order to study genetic mutations, scientists must study genetic material. which statement describes the genetic material scientists are most likely studying? a) they study alleles that contain chromosomes, which are rna.b) they study alleles that contain genes, which are chromosomes.c) they study chromosomes that contain genes, which are dna segments.
