Approximately 25% of the F2 offspring from Mendel's second set of
experiments expressed a different version of the studied trait than their
parents had. Which of the following best describes this set of experiments?

A. Mendel allowed the offspring from his first set of experiments to
self-pollinate.

B. Mendel observed crosses that took place naturally in his gardens.

C. Mendel crossed plants that all expressed the same version of
each trait.

D. Mendel allowed true-breeding plants to self-pollinate.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

a. 35°c

b. 25°c

c. 10°c

d. 40°c
