Answer:
The structure labeled A is the substrate. The enzyme is the black colored thingy on the bottom.
Answer:
-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid
Explanation:
During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.
The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.
As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.
Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
Answer:
The phosphorus in all biological tissues can be traced back to phosphorus weathered from rock.
