Answer:

The smell is one of the senses that is created by the small molecules that are released by the food, aromatic substance, or any substance into the air. When we inhale during the breathing process these small molecules enter our nose and trap in tiny hair of the nose.

These molecules dissolves in mucus present in the nose to reach the specialized receptor cells known as olfactory receptor neurons. These neurons detect the smells and send the information directly to the brain to the olfactory bulbs that work to detect the smell.

You get into an argument with your classmate about whether ATP hydrolysis is required for actin polymerization. You argue that A
Ray Of Light [21]

Answer:

It is a very good discussion debate, although I believe that the most effective way to generate the actin head to generate such a displacement requires a good full energy currency, which is considered much better by ATP.

Regarding the information sought in 1950 (Straub), he was publishing that he could bind ATP and that during the polymerization of the protein to form microfilaments, it hydrolyzed to ADP + Pi, which remained bound to the microfilament.

Straub suggested that this reaction played a role in muscle contraction, but this is only true for smooth muscle and was not verified experimentally until 2001.

At the point where it is stated that ADP + Pi is necessary for the formation of polymers, it is extremely true and a very good posture.

What we can highlight as false in all this argument is that for muscle contraction ATP is not needed, since for it to occur if or if there must be ATP or energy currency.

Explanation:

Then we can conclude that both statements are valid with the difference that in the case of ADP + Pi it requires more evidence.

Insulin helps maintain glucose levels in the blood. If blood glucose levels got very high, what would you expect to see happen t
trapecia [35]

Insulin and glucagon are hormones that help regulate the levels of blood glucose, or sugar, in your body. Glucose, which comes from the food you eat, moves through your bloodstream to help fuel your body.

Insulin and glucagon work together to balance your blood sugar levels, keeping them in the narrow range that your body requires. These hormones are like the yin and yang of blood glucose maintenance. Read on to learn more about how they function and what can happen when they don’t work well.

How are tigers and goldfish are related in two different ways?
11Alexandr11 [23.1K]

Tiger is a top predator in the jungles of Asia and the goldfish is a small species of fish selectively bred in China and they are not at all related.

All living things have the same way of transferring genetic information, trough the DNA molecule. Genetic analyses showed that the last common ancestor (LUCA) of all organisms on Earth has lived 3,5 billion years ago. After that, all living things diverged into separate groups. Tigers and goldfish both are animals and have a common ancestor. Tigers may be in a close relationship with other big cats like lions and cheetahs, but they all have a common ancestor with the goldfish since all vertebrates have a common ancestor that was an ancient fish species.
