Describe the process of making the four major macromolecules.
Answer:
Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

A Cylinder has a diameter of 20 m and a height of 100 cm.
A. 12.56 m^3
B. 314 m^3
C 1256 m^3
D 2000 m^3
Answer:
d
Explanation:
cylinder has a diameter of 20 m and height of 100 cm is 2000mcube
Answer: 314 m^3
Explanation: V = πr²H
H = 1 meter (100cm = 1 meter)
R = 10 meters
V = (3.14)(10m)²(1m)
V = 314 m³
A sample of metal has a mass of 10.5 grams and a volume of 1.21 cm cubed. What is the density of the metal?
Answer:
[tex]\boxed {\boxed {\sf 8.68 \ g/cm^3}}[/tex]
Explanation:
The density of a substance is its mass per unit volume. The formula for calculating density is:
[tex]\rho= \frac{m}{v}[/tex]
The mass of the sample of metal is 10.5 grams. The volume of the sample of metal is 1.21 cubic centimeters.
m= 10.5 g v= 1.21 cm³Substitute these values into the formula.
[tex]\rho= \frac{ 10.5 \ g }{ 1.21 \ cm^3}[/tex]
Divide.
[tex]\rho= 8.67768595 \ g/cm^3[/tex]
The original measurements of mass and volume have 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 7 in the thousandth place (8.67768595) tells us to round the 7 up to an 8.
[tex]\rho \approx 8.68 \ g/cm^3[/tex]
The density of the metal is approximately 8.68 grams per cubic centimeter.

The distance from the Sun to Mercury is 3.598 • 10^7
miles. The distance from the Sun to Neptune is
2.798. 10^9 miles. How far is Mercury from Neptune?
Write your answer in scientific notation.
Answer:
4.44309 × 109 ( 4443090000 kilometres )
2.760936126 × 109 ( 2760936126 miles)
Please make me the brainliest! !!
Answer:
The distance of Mercury to Neptune = The distance from sun to Neptune - The distance from sun to Mercury
= 2.798 . 10^9 - 3.598 . 10^7
= 2.798 . 10^9 - 0.03598 . 10^9
= 10^9 ( 2.798 - 0.03598 )
= 2.76202 . 10^9 miles

19. You have found a mysterious substance that appears to be radioactive. You take a sample to a nuclear chemist who
measures out 100 g. of the substance. Thirty hours later, the chemist tests the sample and finds that 6.25 grams of the
sample remains radioactive. What is the half-life of the sample?
> Nu
> Nu
Answer:
7.5 hours
Explanation:
half life is the a period of time the sample takes to be half the amount it started the period with
it means we can express it as
original amount / (2^n) = current amount
where n is the number of periods
in the problem if we put 100 / (2^n) = 6.25
we will find that n = 4
we divide 30 over 4 and we get that half life of each period will be equal to 7.5
A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The INDEPENDENT variable is *

the gender of the alligator
Answer:
The temperature of the incubator.
Explanation:
The temperature of the incubator would be the independent variable in this scenario because it is what controls the dependent variable. The gender of the alligator depends on the temperature of the incubator.

Why are scientists interested in learning more about dark matter
Answer:
Dark matter and dark energy raise some of the biggest questions in the study of space and physics. Lots of scientists are using observations and math to figure out what these are. This will help us understand more about our amazing universe, where there is always more to discover and more to learn.
Some of the most important concerns in the study of space and physics are raised by dark matter and dark energy. Many scientists are utilizing math and observations to determine what they are.
What is dark matter?
Dark matter is a part of the cosmos that can only be detected by its gravitational pull, not by its brightness. The universe's matter-energy ratio is made up of 30.1 percent dark matter, 69.4 percent dark energy, and "regular" visible matter (0.5 percent).
The existence of dark matter also referred to as the "missing mass," was first suggested by Swiss-American astronomer Fritz Zwicky, who found that the mass of all the stars in the Coma cluster of galaxies only made up about 1% of the mass required to prevent the galaxies from escaping the cluster's gravitational pull in 1933.
Until the 1970s, when American astronomers Vera Rubin and W. Kent Ford observed a similar phenomenon, the existence of this missing mass was unknown. At that time, the mass of the stars visible in a typical galaxy was only about 10% of the mass needed to keep those stars orbiting the galaxy's center.
Generally speaking, the rate at which stars circle the galactic nucleus is independent of how far away from the nucleus they are; in fact, orbital velocity either remains constant or slightly rises with distance instead of decreasing as would be predicted.
This requires a linear relationship between the mass of the galaxy inside the orbit of the stars and their separation from the galaxy's centre. However, this interior material emits no visible light, thus the term "dark matter."
Therefore, many scientists are utilizing math and observations to determine what they are.

why is liquid wax transparent, while solid wax is opaque?
Answer:
hope this helps
Explanation:
it has to do with crystallization in the wax. When solid, the long alkyl chains align and crystallize, and these crystallites scatter light which leads to higher opacity. When heated, the crystallites melt, and the resulting amorphous liquid no longer scatters light.

If you were to fill up a tub with water at the very highest that the water could go, and then sit inside the tub, do you think the water would sink due to your density upon the water, or would you submerge into the water (the water arises above you?)
Answer:
the water would rise above you and spill out
Explanation:
the water would form around you, because the human body is solid, and would take up some of the volume of the tub. the water then goes up due to the added volume.
The following data was collected for a runner's speed: 4mi/hr, 3mi/hr, 6.9mi/hr, and 7mi/hr. Is this data precise
The data collected is not precise.
In science, we define precision as the degree to which scientific measurements yield results having close range of values.
A precise data set has values that are very close to each other.
In this case the values; 4mi/hr, 3mi/hr, 6.9mi/hr, and 7mi/hr are not close to each other.
Therefore, the data set is not precise.
