As you are walking home from studying at the library late one evening, you get startled by a strange sound behind you. This activates your sympathetic nervous system. What affect does this change have on stroke volume? Group of answer choices Stroke volume will increase due to an increase in contractility. Stroke volume will decrease due to reduced blood pressure. Stroke volume will increase due to increased blood pressure. Stroke volume decreases due to an increase in contractility. Stroke volume will increase due to a decrease in contractility.
Answer:
Stroke volume will increase due to an increase in contractility.
Explanation:
When the individual is going through a stressful situation, the sympathetic nervous system, in conjunction with the hypothalamic-pituitary-adrenal (HPA) system, sends signals to prepares the body for stressful situations.
The body gets ready to respond to stress by increasing heart biting frequency and strength, contractibility, blood pressure, stimulating respiration and dilating respiratory tracts.
Stroke volume refers to the blood volume ejected from the ventricles as a result of the heart contraction. As said before, stressful situations increase heart bitting frequency and strength, as well as contractibility. Contractibility also influences stroke volume.
Stroke volume is determined by the difference in values of the end-diastolic volume and the end-systolic volume → SV = EDV - ESV
Contractility is one of the main factors that influence stroke volume, by affecting the end-systolic volume. It does not alter the diastolic volume. Consequently, there is an increase in stroke volume.
The central factor of systolic ejection is the myocardium sarcomere contractibility. The sarcomere´s contractile capability generates strength to become shorter after myosin heads join to the uncovered actin-binding points forming cross-bridges.

Answer: d
Explanation:
A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
D)
The organism was able to transport water through specialized veins.
Answer:
The organism requires sunlight.

What is the correct series of steps for the movement of energy in an ecosystem?
Answer:
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
Explanation:
Answer:
The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.

What happens to energy as it moves up the pyramid?
Energy availability increases.
O Energy availability decreases.
O Energy production outweighs energy consumption.
Energy production and consumption become equal.
Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat./ The pyramid of energy shows that the variety and number of species decreases as you move to higher trophic levels. ... This is also assuming that the organisms of the higher trophic level only eat the one organism. To maintain energy levels, higher organisms must eat more food than those at the lower levels.

Explanation:
Based on Anthony's history, symptoms, and the test results, select your diagnosis.
History: Anthony has had diabetes and high blood pressure for the past 10 years.
Anthony's blood glucose was controlled by a diet and exercise program, but recently he has failed to follow his program and his diabetes has got much worse.
He now needs insulin injections every day to control his blood glucose.
Symptoms: Anthony has been feeling very sick this week, Feet are swollen, Feeling pain in feet and hands
Test results: high concentration of urea and potassium but normal levels of albumin
diagnosis options: liver failure, heart failure, and kidney failure
Answer:
Kidney failure.
Explanation:
The symptoms, and the test results indicates that Anthony has a kidney failure because his feet are swollen, feeling pain in feet and hands are the symptoms of kidney failure. The test shows high concentration of urea and potassium which indicates that the kidney is damaged which can't filter the urea and potassium from the blood so all the symptoms and and test results shows that Anthony has a kidney failure due to diabetes.
Based on the information given, it can be deduced that Anthony has kidney failure.
A kidney failure refers to the condition where the kidney loses the ability to remove waste and balance fluids.
It should be noted that the symptom and the test results show that Anthony has kidney failure. His feet are swollen, feeling pain in his feet and hands are the symptoms of kidney failure.
Also, the test shows a high concentration of urea and potassium which indicates that the kidney is damaged. In this case, he has kidney failure.
