<span>It is used to produce carbohydrate molecules (Carbohydrates are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides are relatively small molecules.). The energy from the light is shuttled from the light reaction to the dark reaction (Calvin Cycle). The energy goes into generating the intermediary ATP and another chemical called NADPH.</span>
The atmospheric gas that forms a mild acid when dissolved in water is carbon dioxide. <span> The inscription on a marble gravestone to become harder and harder to read over time is caused by chemical weathering. Biological evolution is NOT a factor that affects the rate of weathering in rocks.</span>
This is an example of vestigial structure.
Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.
Answer: Mosses gametes are produced by mitosis and ferns gamete are also produced by mitosis.
Explanation:
Mosses and ferns are bryophtes, a group of plants that live in moist habitats and lack true leaves and root.
Mitosis is a form of cell division where a single cell divides to produce two identical daughter cells.
During the life cycle of ferns, the diploid sporophyte produce haploid spores by meiosis. The prothallus of the sporophte produce gametes by mitosis.
In mosses, the diploid sporophyte produce spores from a capsule which open when a small structure operculum degenerates. A single spore germinate to form protenama from which the gametes are produced through mitosis.
