Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

The pancreatic alpha cells that produce glucagon are peptide hormones. It is thought to be the body's primary catabolic hormone since it increases blood levels of glucose and fatty acids. Additionally, it is prescribed as medicine to treat a variety of medical ailments.

When the blood glucose level is too low, the pancreas produces glucagon. Glycogenolysis—the process by which the liver releases glucose into the bloodstream—is triggered by glucagon and occurs in the liver. On the other hand, high blood sugar levels encourage the production of insulin. Insulin-dependent tissues can absorb and utilize glucose with the help of insulin. As a result, the feedback mechanism that maintains steady blood glucose levels includes both glucagon and insulin. Energy expenditure is increased by glucagon, which is higher during stressful situations. The secretin family of hormones includes glucagon.

Answer:

A is your correct answer.

Answer:

A

Explanation:

So to put this in a question, I would rephrase it to:

How does hearing work?

It's a little tough to ELI5 without using using the names of the particular organs but here goes:

Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).

The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.

Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.

In essence, your ear works as follows:

Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.

Cheers,

ROR

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

Cooking, eating, breathing, driving, playing, and other activities all include science. Everything we use and wear, including our brushes, toothpaste, shampoo, talcum powder, and body oils, is a result of scientific innovation. Without all of this, life is inconceivable since it has become essential.

Because everything else explains why a new field of science is developing, which might improve an existing theory but isn't precisely the "best" one, it encourages experimentation from a different angle.

As the cell enters meiosis 1, it's DNA replicates in S phase and then reduces to half when the cell splits into two. Hence, the amount of DNA remains 10 pg.

During meiosis 2, there is no DNA replication but only division between cells, leading to 5 pg of DNA in all four daughter cells.

Monera is one of the five traditional kingdoms of living organisms, which also include Protista, Fungi, Plantae, and Animalia.

The Monera Kingdom includes bacteria and archaea, and some scientists propose that these groups should be split into two separate kingdoms due to their significant molecular and structural differences.

Bacteria can be found in various environments, including soil, water, and inside animals, and they play an important role in many ecological processes, archaea, on the other hand, are often found in extreme environments, such as hot springs and deep ocean hydrothermal vents.

Answer:

Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!

A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.

This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on

a. inheritance of natural variations

b. inheritance of acquired characteristics

c. natural selection

d. survival of the fittest

Inheritance of acquired characteristics. Thus, option "B" is correct.

For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.

Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution
