Answer:
The correct answer is "Jim’s heart rate decreased quickly after 30 minutes since he is in good shape".
Explanation:
I attached the missing graph and the missing options of this question are:
Jim’s heart rate was 60 beats per minute at the start of the test.
Jim’s maximum heart rate during the test was 140 beats per minute.
Jim’s heart rate increased steadily as he continued exercising.
Jim’s heart rate decreased quickly after 30 minutes since he is in good shape.
The correct answer is "Jim’s heart rate decreased quickly after 30 minutes since he is in good shape".
While the first two statements are correct, since they point out data from the graph, the only statement that makes an inference based on the information of the graph is the last one. An inference is a conclusion that was reached base on evidence. In this case, the inference is that Jim is in good shape, and the evidence that was used to reach this conclusion is that his heart rate decreased quickly after 30 minutes.
Answer:
C, D
Explanation:
The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).
Answer:
Biofuels like fuel from microalgae are very costly as compared to fossil fuels.
Explanation:
The cost of biofuels is too high as compared to that of fossil fuel. For instance,
the cost of 1 gallon of algal fuel is $32.81 per gallon while cost of diesel is $2.9 -3.2 per gallon.
However, biofuels are very environment friendly as compared to that of fossil fuels.
