Contact inhibition is best explained by which of the following statements?
a. Contact between neighboring cells triggers reactions leading to inhibition of mitosis. b. As neighboring cells become more tightly packed together, their size is restricted and cytokinesis can no longer occur. c. As cell number increases, the protein kinases they produce compete with neighboring cells, inhibiting mitosis. d. As cell number increases, the level of waste products increase, consequently slowing metabolism leading to mitosis. e. As cell number increases, size restrictions inhibit protein synthesis.
Through meiosis,
a. alternate forms of genes are shuffled. b. parental DNA is divided and distributed to forming gametes. c. the diploid chromosome number is reduced to haploid. d. offspring are provided with new gene combinations. e. all of these occur.
From this figure and your knowledge of geological time scales, we can infer that:
1.Fossils found at point A are similar to those found at point B.
2.The rock formations of region B are much more recent than those of region C.
3.The rock layers and life forms found within are older as you move from layer D to layer A.
4.There are no generalizations to make. You have to carbon date everything regardless of what layer the fossil is found in.
