Explain the effect of activity on a heart rate​

Answers

Answer 1

Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.

Answer 2

Answer:

Pretty much the more activity you do, or the more intense it is, the faster your heartrate will be. Your heart needs blood, and when you're exercising the blood is pumping through your body faster.

What are the compounds used in mitochondria for cellular respiration?

Answers

Most of the steps of cellular respiration take place in the Mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Glucose is Key to keeping the mechanisms of the body in top working order. When our glucose levels are optimal, it often goes unnoticed. But when they stare from recommended boundaries, you’ll notice that unhealthy effect it has a normal functioning.

Oxygen is a colorless, oder less reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.

Mitochondria is an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to for layers and that’s called critstae.

What do you mean by word-wrap? HELP ASSAP Select the correct text in the passage. Sarah has written an outline for an essay. One of her bullet points shows that educating the public about the importance of using seat belts convinces more people to use them. In which part of the outline can this idea be found? Introduction Car accidents are the leading cause of death among teens. Of the teens that died in car accidents last year, more than half of them were not wearing seat belts at the time of the crash. Seat belts may not be comfortable or feel cool to wear, but they can save lives. They reduce serious injuries and deaths by more than half. People tend to use seat belts less often if there are no seat belt laws in their state. In order to prevent injuries, there should be seat belt education in schools, laws to make citizens wear seat belts, and awareness campaigns for the public. Body Paragraph Every school should have some type of health education program. This program should review the importance of healthy eating and exercise, the body systems, and refraining from drugs and alcohol. These things can protect your health and keep you safe. But car accidents are the number one killer for teenagers. In order to prevent deaths, seat belt education needs to be included in health education programs. When students understand the importance of wearing a seat belt, they will be more likely to wear seat belts in the car. In 1985, the Ad Council introduced a commercial featuring the crash test dummies. The ad said, You could learn a lot from a dummy. People wearing seat belts increased from 14% to 79%. Conclusion Taking the time to teach seat belt education in schools, creating laws to make citizens wear seat belts, and using awareness campaigns to educate the public can help prevent injuries and deaths on the road.
