Answer:
Capture methane gas emissions from manure and use it as natural gas.
Explanation:
Capturing methane gas emissions from manure and using it as natural gas is a best practice to help conserve the natural environment. Hence, option B is correct.
What is natural gas?Although ethane, propane, butane, and pentane are present in trace amounts, methane makes up the majority of natural gas. Four hydrogen atoms and one carbon atom make up the methane molecule. In homes across the United States and much of the rest of the world, natural gas has slowly risen to the top of the energy usage list. Compared to more conventional fossil fuels like coal and other hydrocarbons like crude oil, it is more efficient.
Natural gas is used in the business sector to heat buildings and water, run refrigeration and cooling systems, cook, dry clothing, and provide outdoor lighting. Natural gas is sometimes used as a fuel in combined heat and power systems by some commercial consumers.

The main difference between the four nucleotides that make up DNA is that they have differentRequired to answer. Single choice.
Answer:
bases.
Explanation:
Nucleotides are the basic building blocks that make up DNA, consisting of a deoxyribose sugar, phosphate group, and nitrogenous base. The main difference between the four nucleotides is the nitrogenous base, Adenine, Thymine, Guanine, or Cytosine. Adenine pairs with Thymine, and Guanine pairs with Cytosine. The order in which these pairs come in code for proteins and hold genetic information.
How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour
Answer:
The correct answer would be - 25 times more.
Explanation:
The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.
Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -
= (80/16)^2
= (5)^2
= 25 times more.
Thus, the correct answer would be - 25 times.
The correct answer would be - 25 times more.

Farmer Brown tests the hypothesis that the more alfalfa sprouts cattle eat, the more milk they produce. He divides his pasture into four fields and puts twenty cattle in each field. Field 1 cows get no alfalfa sprouts, field 2 cows get ten pounds of sprouts per day, field 3 cows get twenty pounds of sprouts, and field 4 cows get thirty pounds. He feeds all groups fifty pounds of regular hay per day, uses the same breed of cattle, and gives them the same amount of water. He measures gallons of milk produced per cow every day.

Describe how the egg gets from the ovary to the site of fertilisation.
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

What effect does aerosol pollution have on climate?
A. Permafrost thawing
B. Atmospheric cooling
C. Sea level rising
Answer:
Aerosols can influence the Earth's climate in two ways. When the sky is clear (devoid of clouds), aerosols can reflect incoming sunlight back to outer space – the direct effect. This blocks part of the energy that would have reached the surface, thus having a cool effect on the climate.
Explanation:
Aerosol pollution has an atmospheric cooling effect on the climate. Therefore option B is correct.
Aerosol pollution, which refers to the presence of fine particles suspended in the air, can have a significant impact on the climate.
Aerosols, such as sulfate particles from industrial emissions or volcanic ash, can scatter and absorb sunlight in the atmosphere. This leads to a phenomenon known as atmospheric cooling.
Aerosols reflect solar radiation back into space, reducing the amount of sunlight reaching the Earth's surface. This cooling effect counteracts the warming caused by greenhouse gases, such as carbon dioxide.
Therefore option B Atmospheric cooling is correct.

Which of the following is a problem faced by the global economy? A. Decreasing cost of renewable resources O B. Increasing greenhouse gas emissions C. Increasing environmental awareness D. Decreasing human population
Answer:
B. Increasing greenhouse gas emissions
Explanation:
Increasing greenhouse gas emission leads to the global warming which is not only harmful for environment but also harmful for global economy.
Increasing emission of greenhouse gases rises the CO2 levels in the atmosphere which lowers the nutritional value of crops and highly affects the agricultural economy of the globally.
Greenhouse gases increases demand of space cooling which eventually decrease the demand for space heating, which is very costly.
Increasing emission of greenhouse gases has direct impact on climate change and climate change has indirect impact on several sectors which affect economy globally such as mining, manufacturing, trade, and finance.
Hence, the correct answer is "B. Increasing greenhouse gas emissions".

what is the name of the simple chart that shows the flow of energy from one organism to anotherwhat is the name of a network of interconnected food chains showing the energy flow through an ecosystem
Answer:
energy pyramid
Explanation:
An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.
The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.
