Please Explain two ways nitrogen gas in the atmosphere is changed into nitrogen compounds that plants can use. -Thank you all in advance! I do need this by 9:20 Am Eastern Time tomorrow

Answers

Answer 1

Answer: Not sure if this is what your looking for, but hope it helps. Nitrogen gas can be changed into nitrogen compound through nitrogen fixation, which is the conversion of nitrogen gas to ammonia, that are absorbed by the plant to make protein. Another way is through animals eating plants and obtaining nitrogen, which is later released, by decomposes, when the organism dies.

Grass is a producer. It gets its energy from the sun, which i might add is by a process called,"photosynthesis", meaning the grass makes its own food. With this bew energy an animal such as a rabbit comes to eat it, that energy that the grass collected is now the rabbits.

When car tires are on hot pavement for too long, the pressure inside will ___________ and the volume within the tire will _____________. A) increase; decrease due to deflation B) decrease; remain unchanged C) increase; increase and possibly result in a blowout D) increase; remain unchanged as long as the temperature is constantly rising

Answers

When the car is driven at high speed for a long time on rough pavement,
the tires and the air inside them heat up.

That causes the air pressure inside the tires to increase, and the increased
pressure tries to make the tires bigger (they ARE made of rubber, after all).

Normally, the tires do expand a little. But if this goes on for too long, or
if there's a weak spot on the tire, a blowout is possible.

List possible causes of fever and explain the benefits of fever

Answers

Answer:

Fever or elevated body temperature might be caused by:

A virus.

A bacterial infection.

Heat exhaustion.

Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)

A malignant tumor.

Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

A graduated cylinder is filled to an initial volume of 12.7 ml. A rock Is dropped into the graduated cylinder. The final volume of the graduated cylinder is 18.2ml. What is the Rocks volume in both ml and cm3? What method was used to determine this?

Answers

Answer:

V = 5.5 mL

Explanation:

The volume filled in the graduated cylinder is 12.7 mL

now when a stone is dropped into the cylinder then the volume of liquid is raised to final level of 18.2 mL

so as per the theory of given by Archimidies we can say that the volume of the object is exactly same as the volume displaced by the object

So here the volume displaced by the object is given as

$V_(displaced) = V_f - V_i$

$V_(displaced) = 18.2 mL - 12.7 mL$

$V_(displaced) = 5.5 mL$

so the volume of the object is given as

$V = V_(displaced)$

$V = 5.5 mL$

First of all, ml and cm^3 are equal. The volume of the rock is 5.5 ml. This is found by subtracting the volume of just the water from the combined volume of the rock and the water leaving you with just the volume of the rock. This is method is using water displacement.

What is the apparent change in frequency of waves due to the motion of a source? Photoelectric effect Prismatic change Doppler effect Wavelength variability

Answers

Answer: Doppler effect

Explanation:

The Doppler effect refers to the change in a wave perceived frequency when the emitter of the waves, and the receiver (or observer in the case of light) move relative to each other.

In other words, it is the variation of the frequency of a wave due to the relative movement of the source of the wave with respect to its receiver.

Another important aspect is that the effect occurs in all waves (including light and sound). However, it is more noticeable to humans with sound waves.

The Doppler effect is the apparent change in frequency of waves due to the motion of a source.
