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.

Which of the following is not a vascular plant? conifer fern moss flowering plant

scoundrel [369]

The answer is moss.

Mosses are nonvascular seedless plants. Nonvascular plants have simple tissues specialized for internal water transport.
On the other side, vascular plants have vascular tissue which consists of xylem and phloem. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.

Capsular hydrostatic pressure is the chief force pushing water and solutes out of the blood and across the filtration membrane.

frozen [14]

Answer:

False

Explanation:

Capsular hydrostatic pressure is not the main force that pushes water and solutes out of the blood and through the filtration membrane. On the contrary, this pressure acts against the filtration membrane, making it difficult for water and solutes to escape from the blood.

Increasing this pressure decreases the infiltration rate and causes obstruction of the urinary tract that tends to accumulate urine, causing a lot of pain to the patient with Renal Failure.

A nerve poison that blocked neurotransmitter receptors on the dendrites would __________. inactivate the enzyme that degrades th

Svet_ta [14]

The correct answer is: prevent reception of a signal in a receiving neuron

Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.

Drugs that bind to neurotransmitter’s receptor can have two effects on its action:

• Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it

• Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).

An opportunistic predator switches prey, capturing whichever prey species is most abundant. As soon as the prey numbers dwindle

Sunny_sXe [5.5K]

Answer:

The correct answer is keystone predator.

Explanation:

In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.
