Answer: Disinfectant is a chemical formulation which may include biological components used to reduce the population of a microbe from a living or dead surface.
Explanation:
The plant tissue is treated with a disinfectant before culturing it and growing new plants. This is done to remove dirt, dust, foreign particles like pollen, microbes from the plant tissue surface or from plant part. This help in growth of disease free and contamination free plants. The culture can be utilized for different cycles of plant growth as it remains free from any kind of contamination.
The right one for this is “D”
There are three types of hormonal release control (increase or decrease production), which is stimulated by
1. specific molecules, minerals or particular nutrients ( chemical regulation)
2. other hormones (hormonal regulation)
3. input from nervous system. (neural regulation)
If the inhibition is caused by a different hormone, it would be considered hormonal regulation. In the given example, the hormone is produced in the target organ.
However, if the inhibition is due to the accumulation of the hormone itself, then it is an example of a <em>negative feedback</em>.
Yes you do need to make the punnet square.
7) sound energy: crowd cheering, chemical energy: food in the athlete/ crowd, mechanical energy: the movement of the arms and legs of the athlete
8) chemical to mechanical, this happens in the athlete, the food gets converted to ATP which in turn is converted to mechanical energy. and the conversion of chemical energy to heat in the metabolic processes of all the people in that photo.
9) the sunlight travels to earth and into the plant cell to the chloroplasts where photosynthesis takes place carbon dioxide and water are needed for this process. then the plant has a fresh sugar molecule which it joins with other molecules to form a polysaccharide. then the humans come along and gather the plant and its parts. then we consume the plant and break down that starch or the sugar. then we convert the sugars into ATP. that process puts out metabolic heat and then the cell uses the ATP to do work such as contracting to move a muscle.
