the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

Answers

Answer:

Explanation:

the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

The nervous system is made up of two parts. Each part contains billions of neurons. The first part is the central nervous system. It contains the brain and spinal cord, which is a fibrous, ropelike structure that runs through the spinal column down the middle of the back.

The other part is the peripheral nervous system. It consists of thousands of nerves that connect the spinal cord to muscles and sensory receptors. The peripheral nervous system is responsible for reflexes, which help the body avoid serious injury. It's also responsible for the fight or flight response that helps protect you when you feel stress or danger.

Let's examine an individual neuron up close.

Here is a peripheral nerve. Each one of the nerve bundles, or fascicles, contains hundreds of individual nerve.

Here's an individual neuron, with its dendrites, axon, and cell body. The dendrites are tree-like structures. Their job is to receive signals from other neurons and from special sensory cells that tell us about our surroundings.

The cell body is the headquarters of the neuron. It contains the cell's DNA. The axon transmits signals away from the cell body to other neurons. Many neurons are insulated like pieces of electrical wire. The insulation protects them and allows their signals to move faster along the axon. Without it, signals from the brain might never reach muscle groups in the limbs.

Motor neurons are responsible for voluntary control of the muscles all over the body. The operation of the nervous system depends on how well neurons communicate. For an electrical signal to travel between two neurons, it must first be converted to a chemical signal. Then it crosses a space about a millionth of an inch wide. The space is called a synapse. The chemical signal is called a neurotransmitter.

Neurotransmitters allow the billions of neurons in the nervous system to communicate with one another. That's what makes the nervous system the body's master communicator.

5 organelle cells not found in human cells

Hurry homework due in couple minutes

Answers

Answer:

Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.

This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.

Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

Explanation:

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea

Answers

Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)

Explanation:

Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.

What is the greenhouse effect?

Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.

A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.

Therefore the correct option is D.

Tell the story of the predator/prey loop.
If the owl population goes up, then ...


Answers

Answer:

Below : )

Explanation:

Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.

In this scenario, if the owl is the predator, as the population rises, its prey will decrease.

If the owl is the prey, the predators would most likely increase.

Discuss how you would adapt to that situation.

Answers

One way to adapt to this situation would be by reducing water use to strictly necessary activities and collecting water from alternative sources such as rain.

What would change in this situation?

Due to scarcity, in this situation, people could not use water for recreation such as water in pools, and in general water usage is limited.

How to adapt to this situation?

Possibilities are restricted in this situation since it is not a good idea to continue using water excessively. Instead, the best is to:
