Answer:
The reason that gametes are haploid is because neither parent has the full set of genetic information so each must contribute their half to make a whole. An organism has two sets of genes from their parents, half a set from the mother and the other from the father (1/2 + 1/2= 1). So together the information carried by the two haploid cells come together for an organism to form.

Answer:
wind causes by unequal heating of the earth
Explanation:
Because,ocean currents are driven by wind, water density differences and tides.Oceanic currents discribe the movement of water from one location to another.

<span>The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.</span>
Answer:
True.
Explanation:
Honeybees plays a significant and very important role in the field of agriculture because honeybees are the pollinators which is very necessary for agriculture. These honeybees are responsible for the formation of seeds in different crops by transferring pollen grains from stamen to carpel. The other agricultural methods linked with this pollination. If pollination occur, the other methods will also work and has a good impact on the productivity of the crop.
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
