The sympathetic nervous system is a part of the autonomic nervous system that carries stress responses or "flight or flight" responses that involves feelings of rush. The activation of sympathetic nervous system therefore increases the heart rate. The parasympathetic nervous system is another part of the autonomic nervous system which is responsible for "rest and digest" responses that involves feelings of relaxation. The activation of the parasympathetic nervous system decreases the heart rate.
Answer:
Transpiration
Explanation:
Water is absorbed from the soil by the root of plants. Majority of the absorbed water is lost in form of vapor through the stomata of the leaf of plants. This process is called TRANSPIRATION in plants. Transpiration is simply the process whereby water escapes from plants into the atmosphere.
The water leaves in form of a gas (vapor) when the plant opens the stomata on its leaves to enable carbondioxide (CO2) needed for photosynthesis come in and oxygen go out as a waste product of photosynthesis. Since, water in a liquid form leaves in a gaseous form, transpiration is therefore the term used for the evaporation of water in plants.
Answer:
Plant grow using a process called photosynthesis. This is a process in which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and creates oxygen as a byproduct. The plant uses the energy from the sun in order to create energy for itself while at the same time taking up carbon dioxide and water to grow.
Explanation:
The scientists who pioneered the use of the microscope to view to various kinds of microbes was: Leeuwenhoek
Answer:
In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy .
In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).
