Which is the main reason cells are replaced in the body?

2 answers:

8 0

Because if the cells wouldnt be replaced then after a cell dies (which happens very rapidly) we wouldnt exist for very long. the body replaces tons of cells on a daily basis, and if the body stopped making new ones to replace the old, we wouldnt have anymore living cells left in our body.

List two general differences between inner and outer planets. <br><br> Astronomy.

Bumek [7]

Answer:

Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.

Explanation:

The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal.

The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings.

The outer planets are made of hydrogen and helium, so they are called gas giants.

Proteins can be visualized in many ways, each of which highlights a specific aspect of the protein. drag the terms on the left t

Nastasia [14]

Answer:

1. Space-filling

2. Ribbon model

3. Wireframe

4. Simple shape

5. Simplified diagram

Explanation:

"attached is the question"

A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand.

A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent. Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein.

Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows.

Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms.

A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein.

A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.

to is when a stimulus successfully stimulates an action potential in its specific neuron. how your brain interprets the message

Xelga [282]

Information about the body and its surroundings is provided through the senses. Olfaction (smell), gustation (taste), equilibrium (balance and body posture), vision, and hearing are the five distinctive senses that only humans possess. We also have broad senses, sometimes known as somatosensation, that can react to stimuli including pressure, temperature, pain, and vibration. Somatosensation includes the sense of limb position used to monitor kinesthesia (limb movement), proprioception (the position of bones, joints, and muscles), and vestibular sensory, which is an organism's sense of spatial direction and balance. Although the sensory systems connected to these senses vary greatly, they all have the same purpose: to cause the nervous system to produce an electrical signal in response to a stimulus, such as light, sound, or body position.

<h3>What is Action potential ?</h3>

When a neuron transfers information away from the cell body and down an axon, it experiences an action potential. The action potential is also referred to as a "spike" or a "impulse" by neuroscientists. A depolarizing current causes an explosion of electrical activity known as the action potential.

Different ions crossing the neuron membrane result in action potentials. The sodium channels first open in response to a stimulus. Because the inside of the neuron is negative compared to the outside and there are much more sodium ions on the inside, sodium ions rush within the cell.

Depolarization, overshoot, and repolarization are the three phases of an action potential.

Lynna [10]

Answer:

30 percent

Explanation:

Protein is essential in living organisms. They are the building blocks of life and help in the replacement and repair of work out tissues of the body. There are various sources of protein which are plant sources and animal sources.

Animal sources include land and aquatic animals.Sea Finfish, ocean catches, and fish-farming provide approximately 30

percent of animal protein sources consumed by humans in the world.
