Which statement would be used in an argument against the use of human embryonic stem cells for therapy? A. Obtaining embryonic stem cells for use in therapy requires the destruction of embryos.
B. Embryonic stem cells are limited in their ability to become different types of cells.
C. It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy.
D. Embryonic stem cells originate in plants, so the likelihood of rejection by a patient’s body is high.

Explain why the plants cortex would serve as the best food source for animals

2. which of the following statements does not accurately describe stem cells? a. embryonic stem cells make up the inner cell mass of a blastocyst. b. with more research, stem cells may be used to repair or replace damaged cells. c. the use of stem cells is without any objections since it can be used in therapies to humans. d. adult stem cells are multipotent and can differentiate into many types of cells.

Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. the mutation could occur in any region of a gene. the effect of the mutation on the phenotype of the offspring will be determined by where the mutation occurs and its effect on the final gene product. in which of the following scenarios could the mutation alter the phenotype of the offspring? select all of the scenarios that apply the mutation occurs in the promoter and affects the rate of gene transcription. the mutation results in a new, dominant allele the mutation occurs in a portion of an intron not responsible for exon splicing the mutation occurs in a gene that controls development and alters differentiation of a cell type during development. the mutation occurs in a codon and alters the function of the final protein e mutation occurs in a codon, and the amino acid sequence of the final protein is unchanged.
