When a peptide hormone reaches its target cell, which event happens next?

1 answer:

6 0

They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. 

The two most important messengers are cAMP and inositol triphosphate. 

Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. 

Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.

Hope this helps !!!^_~!!!

IF most of the energy we use on earth comes from the sun –how does that energy (light and thermal) end up

____ [38]

Answer:

1: Chemical Energy

2: Kinetic Energy

3: Electrical Energy

4: Mechanical Energy

Explanation:

1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.

2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

3: The power for lights and stuff is Electrical Energy, ofc :]

4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.

Hope this helps!! :D

Part 1: Cats Falling Out of Windows

xenn [34]

The way that the number of injuries per cat relate to the number of stories a cat falls is that:

As we examine the data about cats dropping from a given number of stories, a tendency becomes obvious. The cat sustains more wounds from story one to story eight than in the previous stories combined. Despite the fact that there are fewer injuries in the last category.

<h3>Why do cats survive after jumping off of a tall building?</h3>

High-rise syndrome describes the wounds that cats can get when they fall from a steep height, like an inside second-floor landing or balcony, out a window, down a fire escape, or when they fail to jump from a landing to a higher architectural element, like a ledge or window.

Cats may live comfortably in apartments and high-rise buildings, but we must make sure they have enough stimulation and playtime.

Therefore, According to Jim Usherwood of the Royal Veterinary College's structure and motion lab, stated that cats have long, flexible legs. "They have respectable muscle mass. Since they can jump rather well, the same muscles focus their efforts on slowing down rather than shattering bones."

Ten biotic and five abiotic factor in an ecosystem

Artyom0805 [142]

Biotic:
Animals: animals are consider biotic because they are living things, they breath, walk, eat, sleep, reproduce, and drink water. and since biotic means living things, the animals are under the biotic category.

Plants: same as animals, but with plants they reproduce asexually meaning it requires only one organism to produce another life. Anything with cells in them are consider a living thing.

bacteria: same as plants and animals, they have cells so they are consider a living thing.

There are other types of biotic factors out there like producers, consumers and decomposes. Here are the ten things of biotic:
1. Bamboo plants (producers)
2. Banana Trees (producers)
3. orchids (producers)
4. Seaweeds (producers)
5. anteater (consumers)
6. Bears (consumers)
7.zooplankton (consumers)
8.bacteria (decomposers)
9. earthworms (decomposers)
10. termites (decomposers)

Those are the ten examples of biotic.

Abiotic:
Some of the examples include temperature, sunlight, soil, gases and atmospheric, these are consider the non-living things but here are 5 examples of abiotic factors in the ecosystem.
1. Altitude
2.pollution
3.soil
4.wind
5. Ph
