The alternation of generations
in the life cycle of a plant includes the diploid and haploid multicellular
stages. diploid and haploid are copies of the chromosomes. The spores in the
plant is unicellular and when they start dividing through mitosis, it produces
identical cells. These identical cells are all haploid. Haploid stages contain
one set of chromosome from either of the parent. These identical cells create a
multicellular system called the gametophytes. A gametophyte is the haploid
multicellular stage in the life cycle of a plant. The gametophyte makes the
gametes. These gametes are responsible for sexual fertilization. It takes place
when a sperm (male gametes) from the male fuses into the egg cell (female
gametes) of the female. The formation of both
male and female gametes creates a diploid zygote. Diploid stages
contain one set of chromosome from each parent. This is where the sporophyte
comes in. A sporophyte is the diploid multicellular stage in the life cycle of
the plant. It now contains the two sets of chromosomes from each parent.
The type of
cell division that produces gametes with half the normal chromosome number is
the meiosis. Meiosis is the type of cell division used in sexual reproduction.
It will occur in the testes and ovaries.

#2 B. where an oceanic plate is moving toward a continental plate
#3 A. The seafloor is spreading.<span>

Answer:
Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.
Explanation:
ATP is the required to power the Na+-K+ pump, which is also necessary for maintaining osmotic balance. The pump was requires for the ATP hydrolysis to drive its pumping the cycle. So, in the absence of the ATP production, the Na+ concentration that inside the cell will also increase. This is followed by the passive diffusion of the water across the membrane, causing the cell to be swell.
Adenosine triphosphate (ATP) is the source of the energy for the use and the storage at the cellular level. The structure of the ATP is a nucleoside and triphosphate, consisting of the nitrogenous base (adenine), a ribose sugar, and the three serially bonded of phosphate groups.

I think it the answer B. The salt will cause the water to diffuse out of the plants and they will wilt.
