Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.
Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
Answer:
I and II
Explanation:
I. irrigation of cropland & II. harvest of biomass for energy
Answer:
B
Explanation:
During cellular respiration in most animals and plants, oxygen reacts with carbon containing molecules (sugars) to provide energy to cells of the organism. the flow of energy in organisms.
Los pulmones y el sistema respiratorio permiten la entrada del oxígeno del aire en el organismo, así como la expulsión de dióxido de carbono al espirar. La respiración es el término que se utiliza para denominar el intercambio de oxígeno procedente del entorno por el dióxido de carbono que se produce en las células.
