what is the composition of gastric juice and their functions?​

Answers

Answer:

Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes

Explanation:

The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.

Answers:

It is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. It is found in all vertebrates.

Main function is to inactivate microorganisms.

Answers

Answer:

1.Nitrification happens when soil organisms change over ammonium into nitrate. Much of the cover between the carbon cycle and the nitrogen cycle happens within the soil, in forms conducted by soil organisms. Organisms break down supplements, construct modern compounds for their possess development, and inevitably pass on.

The second question im not sure sorry- the positive and negative one ;(

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like vitality particles, fats and proteins, in the long run cycling its way back into the environment. Nitrogen is basically found within the air as well and enters the environments as supplements for plants. Water, nitrogen and carbon cycles. Carbon moves from the air and back by means of creatures and plants. Nitrogen moves from the environment and back by means of living beings. Water moves on, over, or underneath the surface of the Soil.

How does transferring energy into a container of magnetic marbles affect the speed by shaking the container gently?

Answers

By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.

What is kinetic energy?

All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.

A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B. Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.

Answers

Answer: Felipe is wrong.

Explanation:

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.

Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)

When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

It is only possible to see the moon when it is reflecting sunlight.In this case, no other type of celestial body must be in front of the moon, blocking the sunlight.As we can see in the question above, sunlight is being emitted from left to right.Although the moon is in the right direction to reflect this light, the earth is in front of the moon.Therefore, sunlight will not shine on the moon, because the earth will block it and cast a shadow over the moon.

Therefore, it will not be possible to see the moon, as Felipe said.

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model

Answers

Answer: its C

Explanation:

Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.

A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.

In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.

Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.

Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.

Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.

In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

The universe can be explored using visible and invisible forms of light. These dishes (that detect radio waves from outer space) are part of a much bigger telescope in New Mexico. What is its name? A. Viking B. Voyager C. Very Large Array D. International Space Station

Answers

Answer: C. Very Large Array

There are 28 radio antenna, which are essentially satellite dishes. Only 27 are in operation at any given time, leaving one to sit out for maintenance. Astronomers using this array were able to observe black holes, and also observe the formation of interplanetary disks, among many other applications as well.

The reason why so many dishes are used is to increase the faint signal that is received from such a long distance away (often lightyears away). The 27 dishes are effectively the same as having a single radio dish that is 36 km (22 miles) in diameter. Having such a impossibly massive satellite dish is not feasible, so it's more practical to go with 27 smaller dishes.
