Answer:
We should be concerned about the amount of green house gases released into the atmosphere because the more gases are released, the more they accumulate in the atmosphere and trap heat, which contributes to global warming, which is causing massive changes in our environment all around the world.

Compare and contrast pollution caused by irrigation and by pesticides.
Pesticide pollution and irrigation pollution have different characteristics, but both have the potential to have negative effects on the ecosystem.
Here is a side-by-side comparison of the two:
Pesticide usage and irrigation both have the potential to contaminate water. Excessive irrigation can result in the contamination of nutrients in water bodies due to the leaching of pesticides and fertilisers.
Both pesticides and irrigation can have a negative impact on ecosystems. Excessive irrigation water use can harm aquatic habitats and deplete water supplies.
Pollution sources: Irrigation is a major cause of pollution due to the excessive water use and subsequent discharge of nutrients, silt, and fertilisers.
Pesticides, on the other hand, are chemical compounds created especially to manage pests and have the potential to pollute the environment directly through runoff, spray drift, or persistence in the soil.
Management and Regulation: Irrigation and pesticides are managed and regulated in different ways. Policies for managing water resources and conservation measures can be used to control irrigation practices.
Contrarily, the use of pesticides is subject to stricter laws and oversight to guarantee correct application, handling, and mitigation of side effects.
Thus, this is the comparison and difference between pollution caused by irrigation and by pesticides.

Select all the correct answers. Imagine a car as a model that represents the human body, with its parts performing various functions similar to human body systems. Which two statements are correct analogies?
A. The gas in the car is the digestive system that provides the necessary energy.
B. The frame of the car is the digestive system that provides structure and support to the body.
C.The exhaust system of the car is the excretory system that removes waste.
D. The engine of the car is the digestive system that circulates nutrients to the rest of the body.
E.The oil in the car is the excretory system that protects and coats the body.
Answer:
i took the test it is right C and D plato to
Explanation:
The two statements that correctly represent the analogies are as follows:
The exhaust system of the car is the excretory system that removes waste.The engine of the car is the digestive system that circulates nutrients to the rest of the body.Thus, the correct options are C and D.
What is Analogy?An Analogy may be defined as the condition of comparing two things in order to reveal the identical function of each other. It makes the process of understanding more clear and effective.
The engine of the car is analogous to the digestive of the human. This is because it provides the energy for other parts to function properly.
The exhaust system of the car is analogous to the excretory system of the human. This is because it removes all the waste material out of the car in the form of smoke, dust, etc.
Therefore, the correct options for this question are C and D.

main-sequence stan
black hole
A planet is at equal distance from two stars, Star 1 and Star 2. If both stars have the same mass,
they will not pull each other with a gravitational force
they will pull the planet with equal gravitational force
Star 1 will pull the planet with a greater gravitational force than Star 2
Star 2 will pull the planet with a greater gravitational force than Star 1
Answer:
In this situation both o the stars will pull the planet with equal gravitational force.
Explanation:
The reason behind this is that gravity works according to the mass an object has. Therefore if we have two corpses with the same amount of mass they are going to pull the objects with the same strength. Now, in our case, they have a planet between both of them. Thus, they are going to pull it to them with the same gravitational force because they have the same mass, and are at the same distance. If one of them had a bigger mass that would pull the planet with more gravitational force, as well as if that star was closer to the planet.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%
Answer:
b. The chance of an offspring having white eyes is 50%
Explanation:
So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.
The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).
If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.
Now, let's look at the choices:
A.: The chance of an offspring having red eyes is not 75%; it is 50%.
B.: The chance of an offspring having white eyes is 50%!!!
C.: The chance that a male offspring will have white eyes is 50%, not 0%.
D.: The chance that a male offspring will have white eyes is 50%, not 100%.

What role do the oceans play in moderating climate change?
Group of answer choices
A. Oceans help to reduce the level of water vapor in the atmosphere through condensation.
B. Oceans absorb about 40% of the methane out of the atmosphere that has been produced by rice paddies and livestock.
C, Oceans remove about 25% of the atmospheric carbon dioxide produced by humans.
D. Oceans reflect sunlight back into space before the ultraviolet wavelengths are converted into infrared radiation.
The role that the oceans play in moderating climate change is as follows:
Oceans remove about 25% of the atmospheric carbon dioxide produced by humans.Thus, the correct option for this question is C.
What is Climatic change?Climatic change may be defined as a type of process that significantly involves long-term alterations in the temperature and weather pattern of a particular location. These alterations are completely natural and rely upon the solar cycle.
The role of the oceans is determined by the fact that they regulate the climate of particular locations by absorbing 25-30% of the carbon produced by humans in the environment. Due to this, they are considered the largest store of carbon accounting for approximately 83% of the global carbon cycle.
Therefore, oceans remove about 25% of the atmospheric carbon dioxide produced by humans is the statement that represents the role of oceans that play in moderating climate change. Thus, the correct option for this question is C.
