Answer:

The experiment conducted in 1952 by hershey and chase consisted in the use of sulfur to track proteins and radioactive phosphorus to track DNA from T2 phages that infect bacterial cells, the key result was that phage proteins were outside the cell during the infection but the DNA was inside the cells because new phages were obtained with radioactive phosphorus. This allows us to conclude that DNA acts as a genetic material of phage T2

Which of the following options lists the stages in cellular respiration in the correct order? glycolysis, the citric acid cycle,
marishachu [46]

Answer:

The correct answer is  glycolysis, the citric acid cycle, and oxidative phosphorylation

Explanation:

Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.  

In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.

In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.

So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.

REY [17]

<u>Answer:</u>

Charles Darwin’s study of evolution predicts that genetic evidence would show that all organisms share a common ancestor.

Option: (B)

<u>Explanation: </u>

  • Through his "theory of evolution", Darwin found that the species exist and new species form based on natural selection.
  • He studied the animals and birds in Galapagos island for his evolution theory.  

<u>The four key points of Darwin's Theory of Evolution:</u>

  • individuals of any species are not identical;  
  • genes are passed from one 'generation' to another;
  • more offspring are born than can survive;  
  • only the 'survivors of the competition' for the resources will reproduce.
