Explanation:

Hey (☞゚∀゚)☞ It's the Explanation Wizard here for your troubles I don't wanna waste time so here is my answer+explanation that I have personally wrote for you.The first question you asked here's the a+e The sliding filament model describes the process used by muscles to contract. It is a cycle of repetitive events that causes actin and myosin myofilaments to slide over each other, contracting the sarcomere and generating tension in the muscle. second a+e for second question When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle. Explanation Wizard out

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during which no muscle tension is observed while the neurotransmitter is being released by exocytosis, diffusing across the synaptic cleft, and binding to its receptor to activate the muscle cell. relaxation latent contraction refractory

Answers

Answer:

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.

Explanation:

When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.

While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

At each ______ foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the ______.

Answers

Answer:

At each intervertebral foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the spinal nerves.

Explanation:

The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs.  In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.

Factors that could affect the current oxygen and carbon dioxide levels?

Answers

Explanation:

There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:

Burning of fossil fuels increases the level of carbon dioxide.

Cleaning agricultural land increases the level of carbon dioxide.

The availability of nutrients in plants affects the synthesis of oxygen.

The intensity of the sunlight can increase or decrease the synthesis of oxygen.

Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.

The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.

An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.

A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

Darker skin in equatorial environments is adaptive because it prevents ____________ deficiencies, which cause _____________ in newborns.

Answers

Answer:

Vitamin D

Rickets

Explanation:

Lack of vitamin D causes rickets

Darker skin in  equatorial environments is adaptive because it prevents  vitamin D deficiencies, which cause Rickets in newborns.

What determines skin color?

The pigment melanin is by far the most important factor that determines the color of people's skin, although there are many other factors that play a role. People with darker skin have more melanin, which is the primary pigment responsible for their skin color. Melanocytes, which are cells found in the skin, produce melanin.

People who live closer to the equator typically have darker skin as a form of protection against the sun's ultraviolet (UV) rays. This is because excessive UV exposure can lower folic acid levels and lead to skin cancer.

Black people have more melanin in their skin than people with lighter skin, which affects the body's ability to synthesize vitamin D. People with lighter skin have less melanin in their skin.

Therefore, near equator more sunlight causes increased vitamin D production , preventing rickets in new born.
