Answer:
The correct option is D. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
Nitrogen is an active constituent of amino acids which make up proteins. Nitrogen is also an active constituent of the nitrogenous bases which make up an organism's DNA.
Phosphorus is actively present in the DNA but amino acids lack phosphorus.
Our body is actively made up of DNA and proteins. If the nitrogen was radioactively labelled, the experimental results would be wrong as proteins also have nitrogen in them.
The grains he chooses are large ones so they have a greater chance of producing corn with large grains. Species pass on their genes to their offspring.
Answer: D. T<span>he new crop will be more likely to have grains as large or larger.</span>
A plant absorbs energy from the Sun. Energy absorb by plants is used in the process called photosynthesis. As the plant takes the energy, it process it to turn it into potential energy. And is being used by the consumer of the plants. Hope this answers the question.
The nephritic syndromes produce a proliferative inflammatory response, whereas the nephrotic syndromes produces increase permeability of the glomerulus .Nephrotic cause the body to secrete much protein in the urine while nephritic cause swelling and inflammatory of the glomerulus in the kidney.
Answer:
Most living tissue contains catalase. We can use potatoes to help see catalase work because bubbles of oxygen form when we put potatoes into hydrogen peroxide.
Explanation:
As catalase decomposes hydrogen peroxide into water and oxygen gas, bubbles of oxygen collect on the disk. When the density of the combined paper/enzyme/O2 is less than the solution the disc will rise to the surface.
