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.

In general, what causes a sea breeze?
A. The difference in elevation between land and water
B. The difference in cloud cover between land and water
C. The difference in density between land and water
D. The difference in specific heat capacity between land and water
Need a 100% correct answer please
Answer:
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.

-it is a gas becomes a liquid under moderate pressure or when cold
-it is a portable energy source used in Barbecue grills in hot air balloons
what is it?
The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.
Properties of PropanePropane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.
At cold temperatures or moderate pressure, propane becomes a liquid.
Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.
Answer:
I think is the top one A hope this helps
Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.
What is the energy of the cell?Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.
The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.
To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.
Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

How did the peppered moth's environment change, and what caused this change?
Answer:
Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.
Explanation:
The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.
During the Industrial Revolution, pollution darkened tree trunks in England. This favored dark moths, causing a decline in lighter ones.
What are peppered moths?The peppered moth's environment changed due to the Industrial Revolution in England during the 19th century. Prior to the Industrial Revolution, the trees in England were predominantly light-colored, and the majority of peppered moths were also light-colored, or "typica." However, as a result of industrial pollution, the bark of the trees darkened, becoming covered in soot and ash.
This created a selective advantage for the dark-colored peppered moths, or "melanics," who were better camouflaged against the darkened trees. The change in the moth's environment was caused by the burning of coal in factories, which released soot and other pollutants into the air, leading to widespread pollution and industrialization. This phenomenon is often cited as an example of natural selection in action, as the moths adapted to their changing environment through the evolution of their coloration.

Explanation:
Explain A wood frog species in Alaska can survive being frozen
almost completely solid. In spring it thaws and becomes more
active. Wood frogs that live in warmer climates do not have this
trait. Explain how this trait relates to adaptation and speciation.
Wood frogs are found in the United States throughout the forests of Alabama and Northwest into Idaho. Wood frogs are the only frogs that live North of the Arctic Circle. Adults usually live in woodlands and lay in vernal pools.
Wood frogs live in a variety of habits, from forests to bogs to tundra. They hibernate on land and breed in water.
The Wooded frog does adapt in warmer climates by hibernating by nestling down into the leafy litter on the forest floor.

Many organisms in the ocean (like plankton) rely on this source of food. What effects do you think this change in the decrease speed of the ocean currents could have on living things on the ocean?
Please help
Answer:
If the speed of ocean currents slows down, some living beings in the ocean would find it difficult to feed and reproduce.
Explanation:
As we already know, ocean currents act as a transport chain that transports hot water to the poles and cold water to the tropics. However, this ability to transport ocean currents also acts in the transport of nutrients and food for living beings that live on the seabed and do not move, but live in a fixed place. They also transport the reproductive cells of these beings to other places in the ocean, being important in the reproduction of marine life. If the speed of ocean currents decreases, the feeding and reproduction of some marine life organisms will be impaired.
What is the difference between aggression and courtship?
Answer:
How you approach and talk to the person you like
Explanation:
If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand) for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

How do you think a species population can benefit from being diverse?
Answer:
A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.
