Answer:
Seeds- form through <u><em>sexual </em></u>reproduction and contain an embryo that gives rise to a new plant.
Explanation:
The formation of seeds occur when a ripened ovule is fertilized by pollen. If the pollen and the ovule are from the same plant, then it is termed as self-pollination. If the pollen fertilizes the ovule of another plant then it is known as cross pollination. The seed contains the embryo which has the capability to form and generate into a new plant. Hence, the formation of seeds is a phenomenon which occurs in sexually reproducing plants.
An image is formed due to reflection of light by a plane mirror. In a completely dark room there is no light so no image will be formed by the mirror placed in the room. Hence we will not be able to see our image in a mirror placed in a completely dark room.
Answer:
Dehydration from flu
Explanation:
On centrifugation, blood forms different regions plasma region, the Buffy coat and the hematocrit which contains the erythrocytes or the red blood cells.
The normal range is between 37-52 percent of the total whole blood.
Any value below shows anemia and any value above indicates polycythemia.
Polycythemia is usually a sign of doping in athletes however for this elderly patient. It must have been caused due to dehydration from the flu.
Answer:
D) H in glucose and water; O in O2
Explanation:
In green photosynthesizing plants, photolysis occurs during the light-dependent phase. Photolysis is the splitting of the water molecule in the presence of sunlight. The oxygen atom of water molecules forms oxygen gas that is released as a by-product of photosynthesis. Photolysis also releases electrons and protons from water molecules that finally reduce the NADP into NADPH.
The light-independent phase of photosynthesis fixes reduces CO2 into glucose. NADPH serves as reducing power during the light-independent chemical reactions and therefore, the H atoms from water molecules are incorporated into glucose and water molecules formed during light-independent reactions of photosynthesis.
The answer is A. <span>Solar energy is a renewable resource because it can't be used up, but oil is a nonrenewable resource because it will eventually run out.</span>
