<span>proton gradient</span> establishment
Chemiosmosis is the process that allows the diffusion of a
molecule or an atom through the membrane. Also, it is the movement of ions
across semipermeable membrane down their electrochemical gradients. In chloroplast,
chemiosmotic coupling is an important factor in ATP production through proton
gradient establishment.
Answer: D - Genes move around on the chromosomes and could be located anywhere
Explanation:
Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
Cell Differentiation
Giant sequoias can grow more than 80 meters tall! molecules they need for growth using atoms from the water and air around them. ... Plants take in molecules from water and air around them to make different molecules that can be used for energy and growth.

Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
