Explanation:
don´t forget to brainllest:)
Answer:
The four nitrogen bases that are found in DNA are Adenine, cytosine, guanine, and thymine. The two molecules that make up the sides of the ladder or the side portion of a DNA molecule are Sugars and phosphates. The molecules that meet across the middle, forming the steps of the “ladder'” are known as Nitrogen bases.

A car moves at a speed of 50 kilometers/hour. Its kinetic energy is 400 joules. If the same car moves at a speed of 100 kilometers/hour, then its kinetic energy will be
Answer:
1601.33J
Explanation:
Kinetic energy = 1/2 × mv²
Where;
m = mass (kg)
v = velocity (m/s)
To calculate the kinetic energy of the same car at a different speed, we initially need to calculate the mass of the car.
The initial velocity of the car is 50km/hr = 13.89m/s, while the kinetic energy is 400Joules
K.E = 1/2 × mv²
400 = 1/2 × m × 13.89²
400 = 1/2 × m × 192.93
400 = 96.466m
m = 400/96.466
m = 4.15kg
Mass of the car is 4.15kg
K.E = 1/2mv²
If velocity = 100 kilometers/hour = 27.78m/s
K.E = 1/2 × 4.15 × 27.78²
K.E = 1/2 × 3202.67
K.E = 1601.33J
Answer:
1600j
Explanation:
ke prop to v^2
ke1/v1^2=ke2/v2^2
400/50x50=joules/100x100
400x2x2

If a company developed a way to modify a person's DNA to guarantee certain attributes in offspring, should that company be forced to make their technology available to everyone who wanted it? What are some of the ramifications of widespread use of this type of genetic engineering technology on humankind?
Yes, however, random people should not just be taught because people have a tendency to not follow every step, and can hurt themselves. I learned about this, and that if you modify a persons DNA, that's permanent. If you messed up, your offspring could be impacted. This is why we don't just give out information, because people are afraid that if we messed up, we could end the world or something.

The Sun's radiation provides the energy for all of the following EXCEPT
Answer:
the answer is D :)
The Sun's radiation provides the energy for all phenomena described EXCEPT plate tectonics.
Solar radiation is radiant energy from the Sun, which represents the main source of energy on Earth.The lithosphere, which is the crust and upper mantle of the Earth planet, is divided into different tectonic plates.These plates move due to the heat from radioactive processes within the Earth's (core) interior, thereby solar radiation does not directly provide the input of energy required for this movement.In conclusion, the Sun's radiation provides the energy for all phenomena described EXCEPT plate tectonics.

how are sex linked traits determined
Answer:
A sex-linked trait refers to genes that determine a specific structural or functional characteristic and are found on an X or Y sex chromosome.
Explanation:
The X and Y sex chromosomes are what determine the sex of an individual, XY for male and XX for female. A sex chromosome-linked trait refers to specific genes located on one of the sex chromosomes.
In general, the X sex chromosome is capable of having more traits linked to it because it is larger than the Y chromosome.
Genes are what determine the morphological and functional characteristics of an individual. When specific genes are found on a sex chromosome, the traits that they determine will be given to the offspring through that chromosome.

Is there a time during the cell cycle when you could extract more DNA than normal? When and why?
Answer:
S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Answer:
I'm pretty sure it's B, pressure.
Explanation:
I hope this helped :)
Answer:
Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. ... This lighter magma then rises toward the surface by virtue of its buoyancy.
