A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

Answers

Answer:

Option D

Explanation:

The complete question is

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?

a) Energy was destroyed during certain steps in the experiment.

b) The steps in the experiment required more energy than was available

c) The experiments created energy that was then used up at a faster rate.

d) Some energy was transformed into unwanted heat or sound that was not detected

Solution -

Option D is correct

While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Which of the following statements is NOT correct?
O Heat energy is needed to melt ice into water.
O The most important source of water in the atmosphere is conduction from the oceans.
O Water reaches the land surface as rain or snow and is transported to the ocean by streams, rivers, and lakes.
O Liquid water from the Earth's surface is evaporated into a gaseous form and enters the atmosphere as water vapor.

Answers

Answer:

it's O n2. So, The most important source of water in the atmosphere is conduction...

Explanation:

Hope that helps! (Btw I did this test and got it correct)

The statement "The most important source of water in the atmosphere is conduction from the oceans" is not correct.

The most important source of water in the atmosphere is evaporation.

What is  evaporation?

Evaporation is a process through which a liquid transforms into a gas. It's a type of vaporization that occurs specifically at the surface of a liquid. Whenever a liquid gets heated the molecules, near its surface gain energy. Become more active. These energetic molecules tend to collide with each other resulting in some of them escaping from the liquids surface and entering the gas phase.

In terms of sourcing water for the atmosphere, evaporation of water from the Earths surface plays a role. Although water vapor does come from the oceans through conduction it's not the source that we rely on.

Complete the table below to show the absorption of micro (small) nutrients, that are formed by the digestion of macro (large) nutrients.

Answers

Answer:

The correct answer is -

Protein - amino acids

Glycogen - glucose or monosaccharides

Fats - fatty acids

Explanation:

Once protein sources reach the stomach of an individual, An enzyme called proteases and HCl break these proteins into small amino acid chains that were bonded with a peptide bond, thus protein macronutrient is absorbed in the form of amino acid.

Glycogen is stored in the muscles and liver for energy and digested into glucose by enzymes called amylase and maltase.

Fats are the main source of fatty acid in the body and help in providing fatty acid for the body requirements.
