Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.
Your answer: Here are 3 reasons that go against growing wheat this way.
1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.
2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.
3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.
If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

What happens if you throw a rock hard enough? (Explain escape velocity)
Answer:
it would probably break something depends on were you are
Explanation:
Describe the rock cycle. Discuss what can happen to rock material within the
cycle and the amount of time it might take for rocks to be transformed.
PLZZ HELP I WILL GIVE U A BRAN LEAST !!!!
Answer:
The rock cycle is a constant transformation of rocks between the three rock types of igneous, sedimentary, and metamorphic. If the sediments are buried behind other layers of sediment, they can lithify and form sedimentary rock. When rocks melt, magma is formed. Rocks form deep below the Earth, move and sometimes change, rise to the surface, and eventually return to their original location.
When and where would you expect to find the highest rate of primary productivity
Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.
Explanation:
I explained on the top-
The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.
• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.
• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.
• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.
• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.
• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.
These environments are mainly critical for the sustenance of global biological productivity.

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?
Answer:
mRNA
Explanation:
There are three types of ribonucleic acid (RNA) viz: messenger RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA). These three RNA types function differently from one another. mRNA is a type of RNA that conveys genetic information that was previously stored in DNA into the ribosome for translation i.e. synthesis of amino sequence.
In other words, mRNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain using the amino acid sequence that arise from translating it in the ribosomes.
A water molecule is
Answer:
Water is a chemical compound and polar molecule, which is liquid at standard temperature and pressure. It has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. Water is found almost everywhere on earth and is required by all known life. About 70% of the Earth's surface is covered by water. Water is known to exist, in ice form, on several other bodies in the solar system and beyond, and proof that it exists (or did exist) in liquid form anywhere besides Earth would be strong evidence of extraterrestrial life.

D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
E. Female fish that produce more eggs leave more offspring than those that produce fewer eggs.
Answer:
The Answer is C
Explanation:
When scientists breed cows to produce more milk, this has not occured naturally and thus is not natural selection.
Answer:
C. Scientists breed cows that give greater amounts of milk than their ancestors.
Explanation:
The scientists breed cows that give greater amounts of milk than their ancestors is not an example of natural selection. So, option (C) is correct.
