Answer:
B) increase the length of the ramp
Explanation:
Less force is needed to move the object over a longer distance.
Answer:
You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine can you decrease the effort force needed to push a weight
Explanation:
A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.
Answer:
Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.
Explanation:
The table and data was not attached to the question.
When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)
Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.
That is mass of reactant = mass of product = 100g + 10g = 110g
Sarah got 105g as product because a gas of mass 5g was released during the reaction.
Sarah found the mass of the resulting
mixture without including the mass of the released gas.
A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.
When this is done, the law of conservation of mass would be proven.

Explanation:
The oak and the maple are two different species of trees that also belong to different genera. However, these oak and maples do share many characteristics. Based on their similarities, which levels of classification would they share?
Answer:
Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

Which would a microscope be LEAST useful in studying?
A. spider
B. amoeba
C. bacterium
D. paramecium
Answer:
A
Explanation:
spiders can be seen with the naked eye
Answer:
A
Explanation:
A spider is large enough to see and observe without a microscope. Bacteria, amoeba and paramecium are all very tiny, and can’t be seen with just our eyes. To see these things, we would need a microscope. Therefore, a microscope would be the least useful when studying A: a spider.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.
Explanation:
Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division
Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.
The genetic codesOne of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.
Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.
This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

While Congress has the power to create new laws, they can be vetoed by the President. In addition, the Executive Branch must enforce these laws. What two
different constitutional principles are demonstrated by these relationships?
Select one:
A
checks and balances and separation of powers
B.
separation of powers and eminent domain
C
federal supremacy and due process
D.
separation of powers and quartering of troops
Answer:
A, Checks and balances and separation of powers.
Explanation:
Answer:
The correct answer is:
checks and balances and separation of powers
Explanation:
The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.
Carbon is stored in
A.Trees and other living things
B.Oceans
C.Underground in soil and fossil fuels
D.All are correct
Answer:
all are correct
Explanation:
Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.

Maritime air masses form over water and are humid.
Answer:Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

How does soil quality affect the characteristics of ecosystems?
A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
He should conduct tests using computer models to determine the safety impact.
Explanation:
The other ones either use the material without testing it to make sure it is safe first or publish a report without knowing it's impact on public safety
why do lichens and mosses get mostly replaced by larger plant species during succession
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize
Explanation:
