Answer:
Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.

Explanation:
A student wants to investigate the force of gravity. The student has an apple and a marble. What would be the best way for the student to use these materials? Place the apple on the floor. Roll the marble so it hits the apple. Put both objects on a desk. Push them forward at the same time. Hold both objects at the same height above the floor. Drop them at the same time. Place the marble on a desk. Place the apple next to the marble so the objects touch.
Answer:
Put both objects on a desk
Explanation:
The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.
According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.
Mathematically,
F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.
How do scientists use observations
to make predictions?
Answer:
They use hypotheses to guess a result based on what they already know. Observations are used to record the results of an experiment. Predictions are used to have an expected outcome of a test, thinking the hypothesis is correct. Experiments are used to test the hypothesis.

Answer:
B. The first generation will not have short plants. The short trait will return in the second generation.
Explanation:
If T is for Tall and t is for short, then the first generation doesn't have any short offspring. We can rule out answer choices A and D.
The second generation results in TT, Tt, Tt, tt.
TT is a tall Offspring.
Tt is a Tall Offspring, with a small t as a recessive trait.
tt is a short offspring because both the recessive traits (t) are together.
We can rule out option C.
That leaves us with the correct answer being B. The first generation will not have short offspring, but will pass it on to the second generation, which will have a short offspring (25% chance of having short offspring).

Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?
Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
A. 80
B. 140
C. 150
D. 75
Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.

The photo shows a single-celled organism.
Which sentence best describes what this organism will look like at the end of
its growth period?
A. The same single cell, but larger
B. Two cells, but half the size
C. A small ball of identical cells
D. Three individual cells in a row
Answer:
B. Two cells, but half the size
Explanation:
Single-celled organisms, which are also referred to as unicellular organisms, usually have a growth mechanism or process known as binary fission.
Binary fission is a an asexual reproduction process that involves the division of a mature parent cell into two identical daughter cells of equal sizes that are almost half of their parents cell.
The sentence that best describes how the single-celled organisms shown in the picture above will look like at the end of the growth period is: "b. Two cells, but half the size"

Answer:
Photosynthesis
Explanation:
Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates.
What is the difference between Primary and Secondary Succession?
Answer:
Some differences between primary and secondary succession are:
-Secondary succession happens on a previously existing community that has been cleared.
Another difference would be:
-Pioneer species for secondary succession are adapted differently- they grow quickly, can disperse quickly and have a short life span
And finally:
-Primary succession develops a new community from scratch

Answer:
A. Both of them are correct
Explanation:
Mechanical waves include the movement of water, from ripples in a puddle to giant rolling waves on the surface of the open ocean. For example, water waves (mechanical waves) can transfer energy across an entire ocean basin, even though individual water molecules do not travel great distances.
Electromagnetic propagation through water is very different from propagation through the air because of water's high permittivity and electrical conductivity. Plane-wave attenuation is high compared to air and increases rapidly with frequency.

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.
Year U.S. national debt (in U.S. dollars)
1960 $286,330,760,848.37
1970 $370,918,706,949.93
1980 $907,701,000,000.00
1990 $3,233,313,451,777.25
2000 $5,674,178,209,886.86
2010 $13,561,623,030,891.79
For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.

2010 $13,561,600,000,000.00
While representing a number in scientific notation, it is written as a number between 1 and 10 and then multiplied by a power of 10.
The debt amount becomes,
1960 $2.86×10¹¹
1970 $3.709×10¹¹
1980 $9.077×10¹¹
1990 $3.2333×10¹²

Explain the purpose of cellular respiration .where does it take place ?
Answer:
Cellular respiration, it is an aerobic process in which glucose is combined with oxygen and Adenosine di-phosphate (ADP) to produce carbon dioxide, water, and Adenosine tri-phosphate (ATP).
Cellular respiration takes place in double membraned organelle called mitochondrion.
