what is irrigation ??
Answer:
Irrigation is the artificial process of applying controlled amounts of water to land to assist in the production of crops, but also to grow landscape plants and lawns, where it may be known as watering.
Answer:
Irrigation is the artificial application of water to the soil through various systems of tubes, pumps, and sprays. Irrigation is usually used in areas where rainfall is irregular or dry times or drought is expected. There are many types of irrigation systems, in which water is supplied to the entire field uniformly.

Identify the interaction described.
✔ commensalism
One species benefits and the other species is neither harmed nor helped.
✔ mutualism
Both species benefit.
✔ parasitism
One species benefits and the other species is harmed.
Humans release carbon dioxide that plants need; plants provide oxygen that humans need.
Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.
Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals.
The humans releasing carbon dioxide, tapeworms entering a human’s intestines or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.
What is mutualism?In mutualism, humans release carbon dioxide that plants need; plants provide oxygen that humans need as both species benefit from the interaction. In parasitism, tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human one species benefits at the expense of the other.
In commensalism, remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals as one species benefits from the interaction, while the other is neither helped nor harmed.
Therefore, humans releasing carbon dioxide, tapeworms entering a human’s intestines through contaminated water and stealing nutrients from the human or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.

A cell sends messages to itself via
A. paracrine signaling
B. autocrine signaling
C. the nervous system
D. the endocrine system
A cell sends messages to itself via autocrine signalling. So the correct option is B.
What is autocrine signalling?The type of cell signalling in which a cell releases a signal from itself and then that signal binds to the same cell. The chemical signal that is released from the cells is known as autocrine agents or autocrine signals.
Autocrine agents are usually hormones or chemical signals. They act as ligands and then bind to the receptors that are present in the cells that have produced them. Such kind of receptors is known as autocrine receptors.
When the autocrine agents bind to the autocrine receptors, autocrine stimulation occurs. This is a chemical reaction that is induced within for the necessary functions that need to happen.
This autocrine signalling is observed at early developmental stages and organ formation happens. These are for pain sensation & inflammation regulation.
Cells infected with viruses also produce autocrine signalling. Autocrine signalling also has an important function in cellular homeostasis. For example, progesterone is important as an autocrine signal molecule in breast cancer.
Therefore, the correct option is B.

explain why oxygen and glucose need to be absorbed and waste products need to be removed
Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.
Oxygen is an odor less and colourless gas that is needed by living organisms.
It is absorbed by living organisms because it serves as a source of fuel.
Glucose is a type of carbohydrate called monosaccharide which is gotten from food.
It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.
Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.
If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

1.) Which statement correctly describes the relationship between the volume of a gas and it’s temperature, in Kelvin, assuming pressure is held constant?
A.) The relationship is directly proportional; as temperature increases, volume decreases in the same way.
B.) The relationship is inversely proportional,
As temperature increases, volume decreases in the same way.
C.) The relationship is directly proportional, as temperature increases, volume increases in the same way.
D.) The relationship is inversely proportional, as temperature increases, volume increases in the same way.
2.) which statement explains the molecular changes that occur in an enclosed gas as the pressure increases and the temperature is held constant
A.) an increase in pressure causes particles to move farther apart, decreasing the volume
B.) an increase in pressure causes particles to move farther apart, increasing the volume
C.) an increase in pressure causes particles move closer together, decreasing the volume.
D.) an increase in pressure causes particles to move closer together, increasing the volume.
3.) The ideal gas law is represented by PV = nRT. as volume is held constant and the temperature increases, how would the pressure be expected to change
A.) it will remain constant.
B.) it would decrease.
C.) it would increase
D.) it would become zero
4.) when the pressure of gas decreases, which quantity will increase, assuming all other variables are held constant?
A.) R
B.) n
C.) T
D.) V
5.) two balloons hold two different gases. The gases are held at the same pressure, volume, and temperature. Which quality can difference between the two gases?
A.) The molar volume of each gas
B.) The mass of each gas.
C.) The gas constant of each gas.
D.) The number of moles of each gas
Answer:
1. The relationship is directly proportional; as temperature increases, volume increases in the same way.
2. An increase in pressure causes particles to move closer together, decreasing the volume.
3. It would increase.
4. V
5. The mass of each gas.
Just took it
Remember that the equation for the ideal gas is:
P*V = n*R*T
Where:
P = pressure
V = volume
n = number of moles
R = constant of the ideal gases.
T = temperature.
1) If the pressure is held constant (we also assume n is constant, because usually, the number of moles does not change).
Then we can write
V = (n*R/P)*T
and (n*R/P) is a constant.
Then the above relation is a proportional relation.
So the correct option is C: The relationship is directly proportional, as temperature increases, volume increases in the same way.
2) If the pressure increases and the temperature is held constant, then the equation:
V = (n*R/P)*T
can be used.
Now the temperature is constant, so we can write this as
V = (n*R*T)/P
Where now (n*R*T) is a constant.
So now we have an inversely proportional relation, when P increases, the volume should decreases. And a decrease in volume happens because the molecules move closer together, so the correct option is C:
"an increase in pressure causes particles move closer together, decreasing the volume."
3) Now the volume is constant, then we can write:
P = (n*R/V)*T
Exact same thing as in the first case, this is a proportional relation, so if the temperature increases, also does the pressure.
The correct option is C again.
4) If the pressure decreases then temperature also decreases, as we saw above.
And as the temperature decreases, the volume increases, as we saw in point (2), then the correct option is D, i the pressure decreases, the volume increases.
5) We have two different gases with the same values of T, V, and P.
By the equation:
P*V = n*R*T
And knowing that R is a constant, we can see that n should also be the same value for both gases.
Then the molar volume of each gas, V/n, is also the same.
Finally, the only thing that can be different in the gases is the thing that does not appear in the equation, and that is density/mass. So we can conclude that the gasses have different masses (thus different density, as they have the same volume)
Then the correct option is B; the mass of each gas.
