why do monocultures create insecticide resistance?
Answer:
The problem with monocultures, Wetzel said, is that if an insect likes the crop, that insect has a large food supply to draw from all in one place. Conversely, a field containing a variety of plants does not offer a large block of food for the insect, so it will not get the nutrients it needs to survive and thrive.

Roberto lives inland in North America. He measured the temperature and precipitation during one winter month and calculated the average daily temperature and precipitation amount for each week. He recorded his results in a chart.
Answer: continental polar
Explanation:
Based on the information given in the question, the type of air mass was most likely over his area is referred to as continental polar. Continental polar is typically cold and dry which comes from high latitudes.
Also, since the average temperature was 28°F and average precipitation was 0 inches when calculated by Roberto, then it's continental polar.

Which of the following is the highest level in the organization of living things? (5 points) A.Organ system
B.Organism
C.Tissue
D.Compound
please answer quickly and please make sure its correct!
Answer: B
Explanation: I read the lesson and did the test
Matter can be classified as an element, a compound, or a mixture. The elements sodium (Na)
and chlorine (CI) react with each other to form the compound sodium chloride (NaCl), also
known as table salt. The reaction between sodium and chlorine releases energy. This energy
causes the temperature of the substances in the reaction to increase. When table salt
dissolves in water, a solution is formed, which is a type of mixture.
Which of these changes must happen for elements to become a compound?
elements dissolve in water
a gas becomes a liquid
elements are heated
chemical bonds form between atoms

a gas becomes a liquid

Which of the following is a testable hypothesis?
Cricketers chirp faster when the night is warmer is a testable hypothesis.
What is testable hypothesis?A hypothesis is a theory that attempts to explain or forecast the relationship between two or more variables.
A testable hypothesis is one that can be proven or refuted through experiments, data collection, or personal experience.
A tested hypothesis requires a relationship statement between two or more variables. All of the following terms should be included: "more than," "less than," "greater than," "different from," and "related to." It also needs to be justifiable and consistent with previous research findings.
Thus, we can conclude that option C is correct.

How does surface area and volume factor into the cell’s need to divide?
Proper grammar with accurate punctuation, spelling and complete sentences.
At least 3-5 sentences.
to reproduce simply because they need to reproduce
Answer:
1. Cell divide for many reasons. For instance: when a person skins their knee, cells divide to replace old, dead or damaged cells. Cells also divide so living things grow, organism grow because cells are divided to produce more and more cells.
2. The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. When this happens, the cell must divide into smaller cells with favorable surface area and volume ratios or cease to function. This is why cells are so small.

(15 points) In which of the following circumstances would it be most likely for large organic molecules to form during a laboratory experiment?
The ribozyme is indeed an enzyme made of ribonucleic acid (RNA) which catalyzes a chemical reaction. This ribozyme catalyzes specific reactions in the same way as proteins enzyme do.
Ribozymes, also known as catalytic RNA, are present inside the ribosome, wherein enzymes bind amino acid residues together to make protein.Catalytic methods typically include the catalyst reacting to make an intermediate, which subsequently renews the original catalyst. It interacts with one or more reactants to generate intermediate, which further gives rise to the ultimate result of the reaction.Large organic compounds are also most likely to form during a laboratory experiment if RNA sections that can act as catalysts are generated.Therefore, the answer is "Option 3".

What are main characteristics of cirrus clouds?
Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer.
Cumulus and stratus clouds belong to the low cloud group which exists up to 6,500 feet. Other clouds belonging to this type are stratus, stratocumulus and nimbostratus clouds. Middle clouds include altostratus and altocumulus clouds on the other hand found from 6500 feet to 8000 feet.
Clouds contain electrons that can find their way to the ground as lightning. Since clouds are formed by the condensation of water vapor, they do not affect the weather.
