Question

atp was broken down in order to move molecule z out diffused back into the cell. the energy from the movement was used to move molecule q into the cell. the movement of molecule q into the cell through a protein concentration gradient is an example of _____ which requires
simple diffusion
facilitated diffusion
active transport
osmosis
question 37 (1 point)
the role of __________________ in the body is to create genetic
mitosis
meiosis
transcription
translation

Explanation:

1. For the first question about molecule Q: Active transport moves substances against their concentration gradient and requires energy. Since ATP was broken - down to move molecule Z and the energy was used to move molecule Q against its concentration gradient through a protein, this is active transport. Simple diffusion and facilitated diffusion move substances down their concentration gradient without energy input (except for facilitated diffusion which uses a protein). Osmosis is the diffusion of water across a semi - permeable membrane.
2. For the second question about creating genetic variation: Meiosis is the process that creates genetic variation through processes like crossing - over and independent assortment. Mitosis creates genetically identical cells. Transcription is the process of making RNA from DNA, and translation is the process of making proteins from RNA, neither of which directly create genetic variation in the same way as meiosis.

Answer:

1. C. Active transport
2. B. Meiosis
