Medicine
1 answer:
san4es73 [151]3 years ago
5 0

Answer:

The given statement is TRUE

Explanation:

Friction is a force experienced by a body that resists its motion.

In other words, Friction is the force experienced by the two bodies (with uneven or rough surfaces) when moving against each other.

When an object slides on a surface, the surface area of the object in contact with the surface is more as compared to an object which is rolled on the surface. Therefore, the friction force experienced by the sliding body is greater than the rolling body.

Therefore, we can say that the rolling friction is less than the sliding friction.

Brackets and wires around the teeth are removed by using pliers during a debonding appointment which can last for about 1 hour.

In this process, the polisher is also applied to the teeth to make sure no glue or adhesive substance is left on the teeth.

An antigen is called immunogen when it has some characteristic features  like foreignness, high molecular weight and chemical complexity. An immunogen can initiate both innate and adaptive immune response. Adaptive immune response is memory based and very specific for any particular immunogen.

Some common immunogens are: bacteria, virus, drugs, chemicals, dust, toxins.

Which of the following is true concerning oxygen in regards to aerobic respiration?
andrew-mc [135]

Answer:

Correct answer is c. It is the final electron acceptor in the aerobic respiration.

Explanation:

Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.

Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.

Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
