Which of the following cell types is formed by meiosis? | Sperm cells. |
If an intestinal cell in a butterfly contains 24 chromosomes, a butterfly egg cell would contain? | 12 chromosomes? |
The distribution of chromosomes in one type of cell division is shown in the diagram below. Which process and type of resulting cells are represented in the diagram? | Meiosis, which produces body cells. |
If an intestinal cell in a butterfly contains 24 chromosomes, a butter egg cell would contain what amount of chromosomes? | 12 chromosomes. |
What is one advantage of sexual reproduction? | The offspring inherit a wider variety of genetic information. |
A carrot cell contains 18 chromosomes. Which of the following diagrams illustrates the correct number of chromosomes in new cells produced by mitosis? | 18 before and 18 after on both sides. |
The arrow is pointing to a circled geno type in the square. What geno type does the circled dd represent? | The geno type that any of the children could inherit. |
Which of the following activities occurs in the G1 phase? | Growth of the cell. |
In humans, the allele for unattached earlobes Q is dominant to the allele for attached earlobes q. An offspring with attached earlobes is indicated in? | Box 4 because box 4 is qq. |
'A hospital wants to identify the parents of a baby. Based on the DNA fingerprints, which couple is most likely the parents of the baby? | Couple x. |

Scientists think that the whale evolved from the Ambulocetus. What information should they use to support their hypothesis? | Examination of the body structures of both animals. |
The insects live on trees. A black fungi starts to grow on the side of the tree where the insects live. Which graph represents the growth of the fugal on the side where the insects live? | B because the light side increases as it hits the dark side then the rate of the tree being dark begins to drastically drop as the inserts growth rate increases. |
