The most used instruments for the determination of free-living physical activity and energy expenditure are; whole-room indirect calorimeter, Accelerometers and pedometers and also the Doubly-Labeled Water. Indirect calorimetry measures gas exchange from which energy expenditure can be estimated, Double labeled water is the most relevant method for measuring free-living energy expenditure in animals and humans, it is based on exponential disappearance from the body of the stable isotopes (H and O) after a bolus dose of water. Accelerometers and pedometers provide an inexpensive overall measure of physical activity, however they are unable to asses the intensity, frequency and duration of activity or to estimate energy expenditure.

Jose and Karl were both exposed to the influenza virus at work. Jose had a flu shot made from killed influenza virus six weeks a
ipn [44]

The correct answer is Karl will get sick and Jose will not this time, but neither will get this influenza again since they both will have acquired active immunity to it.

In the case of Jose artificially active immunity has been induced due to vaccination. A vaccine instigates a primary response against the antigen without resulting in any signs of the disease. On the other hand, Karl will acquire active immunity naturally in future, as when an individual get exposed to a live pathogen, he or she develops the disease, and turns immune as an outcome of the primary immune response.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

Growing a nursery of crop seedlings then transplanting them at the appropriate time is a facet of which agricultural technique?
Jobisdone [24]

Answer:

rice cultivation.

Explanation:

There are two methods of sowing a crop in the field i. e. sowing of seed and transplanting. Seeds sowing in the field is used for almost all the crops except rice in which transplantation is done. In transplanting method, plants are grown inside a nursery and when the plant reaches to a certain height, it is transported to the field. This method is done in the cultivation of paddy rice because water is present at a certain height in the field and rice is the only crop in which roots respire in water.

What molecule is the source of information for transcription.
Grace [21]

DNA is the molecule, which is the source of information for transcription.

• During the process of transcription, RNA polymerase is an enzyme, which is accountable for copying a sequence of DNA into a sequence of RNA.

• The RNA polymerase monitors the phenomenon of transcription.

• At the time of transcription, the information is stored within a molecule of DNA, which is further copied into a new molecule of messenger RNA.

Thus, the correct answer is DNA.
