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.

Calculate the mass of the book on the moon.
On moon surface gravity (g) is 1.6 N/kg
Answer:
The Moon has a smaller mass than the Earth and so the pull of gravity by the moon on an object is smaller than on the earth. The moon has a smaller gravitational field strength. On the Moon, g = 1.6 N/kg.

Predict: Why aren't all organisms made of just one cell?
Why do cells divide, instead of simply growing larger?
The living beings that are comprised of more than one sort of cell are known as Multicellular Organisms.
Why organisms are made up of cells?These organelles are liable for an assortment of cell capacities, for example, acquiring supplements, creating energy, and making proteins. Unicellular living beings are comprised of just a single cell that completes each of the capacities required by the organic entity, while multicellular creatures utilize various cells to work.
Cells divide because:
Cells need to separate for your body to develop and for body tissue, for example, skin to restore itself ceaselessly.

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.

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.

Answer: Mendel
Explanation:
Answer:
Gregor Mendel
Explanation:
-Dr. Walter Snelling discovered in 1911
-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.
