What is muscle?

Muscle is defined as the group of the tissue and contraction has been defined as an action potential travels along the nerves to the muscle. The beginning of the muscle contraction which has been occurs with the signal generated from the nervous system.There are generally two types of the muscle contraction and the situation occur when the muscle contracts and the change in the size takes place.

Isotonic concentric contraction h been known as the type of muscle contraction in which muscle has been shortening takes place. Isotonic eccentric contraction has been the type of the muscle contraction in which the muscle lengthening whilst it is under tension.

Therefore, 1 - Brachialis, 2 - Brachioradialis, 3- Pronator teres, 4 - Palmaris Longus, 5 - Extensor carpi radialis, 6 - Extensor digitorum.

How does anesthesia work?

Answers

anesthetics induce a different sort of anesthetic state, one of general insensibility to pain. The patient loses awareness yet his vital physiologic functions, such as breathing and maintenance of blood pressure, continue to function. Less is known about the mechanism of action of general anesthetics compared to locals, despite their use for more than 150 years. The most commonly used general anesthetic agents are administered by breathing and are thus termed inhalational or volatile anesthetics. They are structurally related to ether, the original anesthetic. Their primary site of action is in the central nervous system, where they inhibit nerve transmission by a mechanism distinct from that of local anesthetics. The general anesthetics cause a reduction in nerve transmission at synapses, the sites at which neurotransmitters are released and exert their initial action in the body.

How do enzymes affect the reactions in living cells?

Answers

Answer:

enzymes speed up the reaction

Answer: Raymond Wang: How germs travel on planes – and how we can stop them

1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?

In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.

2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.

It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.

3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?

He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.

Answer:

4.

Explanation:

Describe Wang’s solution for easily preventing the spread of disease on airplanes? What does “flow,” a word seen in the unit, have to do with his solution? The thing he made to prevent people from getting sneezes in their face is by making the bacteria flow straight towards the filters, so no one gets the bacteria in their faces.

Answers

The answer is oxygen

The product that is also formed apart from the carbon dioxide during the cellular respiration process is water. The correct option is A.

What is cellular respiration?

Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which is then used to drive ATP production.

Cellular respiration is the process by which cells in plants and animals convert sugar into energy, which is then used to perform cellular work.

The goal of cellular respiration is straightforward is that it provides cells with the energy they require to function.

Carbon dioxide and water are the byproducts of cellular respiration. Carbon dioxide is exhaled from your lungs after being transported from your mitochondria to your red blood cells. ATP is produced during the process.

Thus, the correct option is A.
