Which of the following best describes a factor in the evolution of plants that led to their success in surviving on land? (2 points)
Xylem developed to transport water from the plants roots to the rest of the plant.
A waxy cuticle developed to prevent plants from being eaten by herbivores.
Stomata developed to allow water to enter the plants leaves from the atmosphere.
Seeds developed to provide a place for the plants genetic information to be stored.

Q1.8. continuing your studies, you perform a transplant experiment. you chisel up multiple rocks from the upper intertidal zone, each holding 10 individuals of species a, and move them to the lower intertidal zone among individuals of species c. you count the number of individuals of all species on the rocks every day for 30 days. based on your findings, what can you conclude? (remember that all 3 species settle in this zone at equal rates.)

Which class of molecules contains the amino group, nh2 (a) sugars (b) water (c) proteins (d) hydrocarbons

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
