The answer is Walter Hess

Hess manipulated the diancephalon of the brain of cats by inserting metal rods in the hypothalamus regions of the brain, where the diencephalon is located, and passing electrical current through the rods to the brain region. He noticed that the cats, among other complex behavioral changes, would curl up and sleep.

Termites get almost all their energy from eating wood and dead plants. Although termites rely on wood for food, they cannot dige
shusha [124]

Answer:

<em>A. Both are eukaryotic</em>

Explanation:

Despite the fact that termites are insects that eat wood, termites are not equipped for processing wood all alone. Endosymbionts like trichonympha that live inside the digestive tracts of the termite help with converting over the wood into nutrients that the termite can process.

Trichonympha have the enzymes that can convert cellulose in wood into starches and sugars that the termite can use for their nutrition. In return, these living beings profit by the nonstop supply of energy rich cellulose and an appropriate domain in which to live. Both trichonympha and termites show mutualism.

Jim's heart rate was monitored during periods of exercise and periods of rest. The graph shows the result of one 50-minute
DaniilM [7]

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.
