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.

what are the advantages and disadvantages of both asexual and sexual repoduction
?
Answer:
Asexual Reproduction advantage: Time Efficient; no need to search for mate, requires less energy.
Asexual Reproduction disadvantage: No variation - if the parent has a genetic disease, offspring does too.
Sexual Reproduction advantage: Variation, Unique, organism is more protected.
Sexual Reproduction disadvantage: Requires two organisms, requires more energy.

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.

What is most important to controlling climate on Earth? *
Answer:
Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”. The greenhouse effect makes the earth warmer, just as a greenhouse is warmer than its surroundings. Carbon dioxide is the main cause of human-induced climate change.

Forest A consists of only Oak trees and Forest B has Oak trees, Maple trees, and some pine trees. Which of the following is true?
Question 3 options:
Forest B has more biodiversity than Forest A.
Forest A has more biodiversity than Forest B.
Forest B, which has more tree species, is more biodiversity compared to Forest A that has just one tree species. The true statement is: "Forest B has more biodiversity than Forest A."
Biodiversity can simply be described as the variation that exist within an ecosystem whereby different organisms and species can be found in a particular habitat. The more varied the species that exist in an ecosystem are, the higher the biodiversity that exists.
Like the saying goes: "variety is the spice of life". The higher the biodiversity the better. Which means the more varied the species or organisms found in an habitat or ecosystem, the more functional the ecosystem would be.
In Forest A, only one tree species, which is Oak trees exist compared to Forest B that has different tree species.
Therefore, Forest B will have more biodiversity than Forest A.

Which type of succession take less time and why?
Answer:
Explanation:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

What are the features of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction.
DNA is a complex, long-chained molecule that contains the genetic blueprint for building and maintaining all living organisms. Found in nearly all cells, DNA carries the instructions needed to create proteins, specific molecules essential to the development and functioning of the body.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
