The lock-and-key analogy is used to describe the Group of answer choices binding of G proteins to transmitter receptors. activation of the nerve impulse. action of transmitter molecules on receptor proteins. degradation of transmitter molecules by enzymes.

Answers

Answer:

The correct option is the degradation of the transmitter molecules by enzymes.

Explanation:

The key lock system is a type of enzymatic catalysis / anabolization, and is so called because the enzyme that reacts with its substrate is in the male-female or key lock format.

Enzymes can also react by other mechanisms, but this is known for the perfect fit of the substrate with the binding site, since one represents the negative of the other, once joined and the reaction started, the active site is occupied and the enzyme is not reacts with another substrate simultaneously to that one.

what happens if stomach is removed

Answers

Answer: you die

Explanation:

Answer:

What happens after your stomach is removed?After surgery, the way you eat and digest food will change, and it’s important that you carefully follow your doctor’s recommendations for eating to ensure your body is absorbing much-needed nutrients.

“It is important to try to consume as many calories as possible to minimize rapid weight loss in the first few months following surgery, and to take in nutrients that the body needs to aid in the healing process,” said Jeffrey M. Farma, MD, FACS, a surgical oncologist at Fox Chase Cancer Center.

“Eventually the desire to eat and enjoy food will return,” he said.

Eating after your gastrectomyWithout your stomach, you aren’t able to handle regular portions of food and may not even feel hungry. Even if you are not hungry, it is important to remember that nutrition is a vital part of your health.

You will need to eat smaller amounts of food more often – six to eight small meals a day. Your doctor or nutritionist may also recommend that you stay upright for some time after eating. Your health care team can help you adjust your diet if you are having problems eating.

Some patients may experience a condition called dumping syndrome. When part or all of the stomach is removed, the food that is swallowed quickly passes into the intestine, leading to problems with nausea, diarrhea, sweating and flushing after eating. There are treatments to help with these symptoms.

“Since the stomach is no longer there to do the grinding and breakdown of food, it is important that patients take small bites and thoroughly chew the food,” Farma said.

Maintaining your weight without a stomachConsuming enough calories to return to your favorite activities will happen over time. Nutritious, high calorie, low sugar foods provide the best bang for the bite. Calories are your body’s first priority.

“You will not be able to eat the same quantity of food as you did before your surgery, so it is important to get the calories in smaller amounts of high calorie foods,” Farma suggested.

Dietary guidelinesEat a variety of foods including fruits, vegetables, whole grains, protein-rich foods and dairy, which provide a good balance for every meal.

Try not to go for more than 2 or 3 hours without eating.

Carry healthy snacks so you can take a bite here and there.

Nutrient-dense liquids can provide needed calories and are sometimes easier to consume than solid foods. Consider drinking milk, eggnog or unsweetened juice instead of coffee, tea or water.

While you can’t change the fact that your digestive system is different, you can change your diet and lifestyle to enjoy a full and rewarding life after surgery.

Functions of: [A] nucleolus [B] plasma membrane.

Answers

Answer:

The nucleolus is considered as the brain of the nucleus. It occupies around 25% of the volume of the nucleus. It is mainly involved in the production of subunits which then together form ribosomes. Therefore, nucleolus plays an important role in protein synthesis and the production of ribosomes in eukaryotic cells.

The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

A

Explanation:

a. contain checkpoints that determine if the cycle will continue.

b. help move chromosomes to the new daughter cells.

c. produce more chromosomes before the cell divides.

d. grow and produce enough cytoplasm to fill two cells.

The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.

The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.

At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.

At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.

At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.

The correct option is therefore, A.

If a man has red-green color blindness, a sex-linked dominant trait, what is a possible genotype of his father? I. XR Y II. Xr Y III. XR XR IV XR Xr A. Only III B. I and III C. I and II D. I, III, and IV

Answers

Answer:

C

Explanation:

The possible genotype of his father is [tex]X^RY[/tex] and [tex]X^rY[/tex].

For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.

The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.

Hence, in this case, the father can either be affected for the same trait ([tex]X^RY[/tex]) or be free from it ([tex]X^rY[/tex]).

The correct option is C.

What is earthquake and its causes?

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates.

Crop rotation is a method of soil conservation because _______. a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients

Answers

Answer:

d. It avoids the depletion of soil nutrients.

Explanation:

Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.

Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.

Thus, the correct answer is option d.

which words in the sonnet indicate that the tone is satirical ?

Answers

Answer:

"black wires"

"reeks".

Explanation:

William Shakespeare's "Sonnet 130" is a satire or mocking critique of the conventional sonnets that writers write. In this sonnet, he talks of a young lady who is short of conventional beauty ideals.

In the given lines from the sonnet, the poet/ speaker talks of his mistress whose "eyes are nothing like the sun" and he keeps on describing her features as opposed to one praising his lover. Rather, the speaker in this sonnet uses the negative descriptions in describing his mistress, like calling her hair "black wires" and her breath "reeks", far from the delightful perfumes that a lady is supposed to exude.

Thus, the two words that have a satirical tone in the sonnet are "black wires" and "reeks".
