Answer:
An annemometer is an instrument for measuring the speed of the wind, or of any current of gas.
Explanation:
The control tube means a protective sheath for guiding the control cable. The controlling tube connects the control drive mechanism to the radiographic exposure device.
:]
You can carry out a test ,
1- take a sample of the air in a test tube
2-add limewater to the test tube
3- result : if it turns milky/cloudy it has microorganisms
4- reason: because every microorganism respires , and so it produces Carbon dioxide .
and limewater is the test to show the presence of Carbon dioxide .
The true statement about the aquaculture is that It means “cultivating small acreages of land.”
Option C
Explanation:
The aquaculture is cultivating the small acreage of land which means that the fishes, molluscans, crustaceans and similar other aquatic animals can be grown within a confined space with the necessary developed environment.
The freshwater and marine water both can be controlled artificially in which the aquaculture can be developed. Specifically it does not involved water bodies in all to be necessary. large aquarium or pond or tanks are not necessary.
Answer:
As long as oxygen is present, the glucose stored in the ingested carbohydrates can provide a steady stream of ATP, thus meeting the demands of prolonged periods of exercise.
Explanation:
This is the strategy of carbohydrate loading. it is nutritional-performance techniques of storing carbohydrate as glycogen in livers and muscles, so that an athlete has enough supply of energy as ATPs ( from the metabolism of glycogen as glucose) for sustenance needed for entire duration of enduring race.
For maximum performance in long distance races, energy in form of ATP is needed. The mechanisms of substrate level, Kreb's Cycle,and oxidative phosphorylation ensures that stored glycogen in muscles and liver when converted to glucose produce enough steady ATPs for the muscles and therefore for sustenance. Oxygen is the main drive, as combustion fuel for these process to progress.It is the main electron acceptor for the ETC, that ensures steady supply of Energy for ATPs synthesis.
Therefore as long as there is supply of oxygen, stored CHO, can supply enough ATPs for the muscles to improve performance. Thus if carbohydrate is stored as glycogen in liver and muscles, and there is no oxygen to burn it, no energy can be supplied.Thus the storage of glucose and availability of oxygen is essential.
