Answer:
Following are the seven basic requirements of plants to grow properly.
1) Light: Light is the basic need of plant. With the help of light, photosynthesis occurs.
2)Water: Water is used by the plants as a reactant in making their own food.
3) Temperature: In optimum temperature, plants grow fast.
4) Time: There is proper time for the sowing of every plant.
5) Nutrients: Nutrients are food of plants which are used for their growth and development.
6) Proper place or medium: Plants require a soft nutritious soil for germination.
7) Air: Plants need air because it contains oxygen and carbondioxide which is used by the plants during photosynthesis and respiration.
Answer:
She can conclude that the reaction started with three nitrogen atoms because she can be based in the law of conservation of matter which states that the amount of matter in a system is conserved: there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
Explanation:
In science, a law is a general statement that explains a large number of observations. One law that provides the foundation for understanding in chemistry is the law of conservation of matter: it states that in any given system that is closed to the transfer of matter (in and out), the amount of matter in the system stays constant, or in other words, the amount of matter in a system is conserved.
So, in this case, for Marcia to conclude that the reaction started with three nitrogen atoms, she can be based in the law of conservation of matter, and because the matter of that system is conserved, there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
Answer:
is caused by an abnormal infectious protein in the brain called a prion. Proteins are molecules made up of amino acids that help the cells in our body function.
Explanation:
Answer:
Rainforest
Explanation:
Sunlight is a major limiting factor in the rainforest due to a very dense canopy created by taller trees and thus sunlight is blocked from reaching the rainforest floor making underbrush growth sparse. In rainforest, plant growth is confined to the surface due to limitations of light penetration as light intensity decreases with depth.
