Answer:   Yes

Explanation:

The kinetic energy of the moving blades does work in moving air through the fan blades.

The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.

Yes, the fan’s blades have kinetic energy. The blades are in motion and they do work by causing the air to move through the fan blades.

How does the burning of fossil fuels and deforestation contribute to the overall amount of carbon dioxide?
Vaselesa [24]

Answer:

Forests store large amounts of carbon. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago (before dinosaurs existed), is released into the atmosphere in the form of carbon dioxide. .

mrs_skeptik [129]

Answer:

Vacuoles.

Explanation:

Eukaryotic cells contain well membrane bound nucleus. Their cell organelles are divided into structural and functional compartment by the endomembrane system.

The large compartment that maintains turgor pressure is vacuole. Vacuoles are generally present in plants and maintain the disposal of cellular waste and storage of toxic materials.

Thus, the answer is vacuole.

In a certain mutant strain of bacteria, the enzyme leucyl-tRNA synthetase mistakenly attaches isoleucine to leucyl-tRNA 10% of t
Effectus [21]

Answer:

The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

Explanation:

The missing options of this question are:

A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.

B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.

C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.

D. no proteins, because the inappropriately activated tRNAs will block translation

The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.
