Answer:
any of a series of chemical reactions in photosynthesis not requiring the presence of light and involving the reduction of carbon dioxide to form carbohydrate especially the Calvin cycle.
Explanation:
Answer:
The stomata controls the flow of gases in and out of the leaves.
Explanation:
The opening and closing of the stomata controls gas flow in leaves. This controls is necessary to prevent excessive loss of water as vapour from the plant body via transpiration. Usually stomata opens in the day and closes in the night. Each stoma or stomatal wall is flanked by two bean-shaped guard cells, the only epidermal cells with chloroplasts. The wall of the guard cells next to the pore are thicker than those adjacent to the epidermal cells. Here,,the thicker wall cannot stretch as much as the thinner walls.
Answer:
Acorns
Explanation:
The first trophic level consists of producers or plants. The only plant on the list is acorns.
56 grams per day for men, but really varies based on weight, age, and other factors.
Answer:
The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.
Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:

Collision: when two continental plates are shoved together
Subduction: when one plate plunges beneath another (Fig. 7.15)
Spreading: when two plates are pushed apart (Fig. 7.15)
Transform faulting: when two plates slide past each othe
