Xavier is describing the role of electron carriers, such as NADP+, in photosynthesis. Which property of NADP+ should Xavier cite? A. the chemical bonds formed by electrons in its molecular structure B. its ability to accept and release high-energy electrons and a hydrogen ion C. its reactivity with oxygen, water, and carbon dioxide D. its ability to emit a stream of electrons in a nuclear reaction

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

well, i believe that the answer is 2. : 3

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
