The features of the ocean floor are not permanent, and are gradually changing over time due to the movement of tectonic plates. Most of the ocean floor features from close to where the plates are shifting either towards or away from each other. Marine ecosystems are found around parts of the ocean floor features, even the Mariana Trench, which is the deepest trench in the world.

Explanation:
i just answered it :))
In different types of plate boundaries, various geological features occur such as volcano and mountain formation.
What are plate boundaries?Plate boundaries are the areas where the edges of two tectonic plates meet.
Plate boundaries can either be divergent, convergent, or transform.
At different plate boundaries, different geological activities occur.
At convergent plate boundaries, subduction occurs.At divergent plate boundaroes, new crust forms.At convergent plate boundaries, mountains form.At convergent plate boundaries, volcanoes form. At transform plate boundaries, a river change its path.Therefore, at different types of plate boundaries, various geological features occur.

Calculate the volume occupied by 2.00 moles of H2 at 300.0 Kand 1.25
atm
Answer:
39.4 Liters
Explanation:
Using the general gas law equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = 1.25atm
V = ?
T = 300K
n = 2.00mol
Using PV = nRT
V = nRT/P
V = (2 × 0.0821 × 300) ÷ 1.25
V = 49.26 ÷ 1.25
V = 39.41
V = 39.4 Liters

Analyzing models compare an atom’s structure to a ladder. Identify one way in which ladder is not a good model from the atom.
Answer:
Climbing a ladder assumes that you would touch/use each step only once. Electrons will take one layer that is empty first, and previous layers or "steps" will continue being filled with additional electrons only when every other layer is occupied by, at least, one electron.

3. How does genetic variation allow humans to survive long-term? Which
type of reproduction is responsible for genetic variation?
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Genetic variation lets the organisms survive long term as it increases the phenotypic and the genotypic variation. Genetic variation is due to the type of reproduction that involves two parents.
What is genetic variation?Genetic variation is the modification of the original genome of the organism by genetic recombination and mutation that can be beneficial in the survival and the natural selection process.
Reproduction involving two parents of the same species allow genetic variation as the process of independent assortment and crossing over of the chromosomes inherited from both creates species with different traits and genotype.
Therefore, the reproduction involving two parents results in genetic variation.

What causes lava to not instantly melt ice sheets when it is poured onto it?
Answer:
Dry ice
Explanation:
Answer:
The lava doesn't melt through ice because the steam ice sits on top of a blanket of steam rather than on top of the ice itself. This means the friction between the lava and the ice is very low.

Alesha, Kayden,Leo and Caroline are lab partners. They completed the lab in which they put a small marshmallow in a closed, see-through container. They then pushed a plunger down to decrease the volume of the container. They observed the marshmallow looking squished and crumpled. For their lab write up, they must identify the relationship between volume, temperature and pressure of a gas to explain what they saw during this experiment. Determine which student is correct from the statements below.
A.
Alesha says the lab showed that when volume is decreased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.
B.
Caroline says the lab showed that when volume is increased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.
C.
Kayden says lab showed that when volume is decreased, temperature is increased. The increase in the temperature in the container is what made the marshmallow look squished and crumpled.
D.
Leo says the lab showed they increased the temperature of the container by breathing on it and decreased the volume by pushing down the plunger. Both of increasing the temperature and decreasing the volume caused the pressure to decrease and make the marshmallow look squished and crumpled.
What is the molarity of a solution made by diluting 0.025L of 6.0 M HCl until
the final volume of the solution is 1.75 L?
Answer:
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 6.0 M
V1 = 0.025 L
M2 = ?
V2 = 1.75 L
(6.0 M)(0.025 L) = M2(1.75 L)
Solve for M2 --> M2 = 0.086 M HCl

What happened during the fusion reaction shown?
Answer:
the answer to this question B. Two H nuclei that fused into one He necleus
Explanation:
Two hydrogen atoms fused to one helium molecule, hence option B is correct.
What is fusion?Fusion is defined as a process in which two or more atomic nuclei unite to create new atomic and subatomic particles. Heat, which is produced when two atoms fuse, is the key to generating energy. Similar to how nuclear fission produces energy, this heat can be utilized to warm water, produce steam, and turn turbines to produce electricity.
In the core of the Sun, hydrogen is being converted to helium. This phenomenon is known as nuclear fusion. Fusion is what powers both the sun and the stars. One example of this kind of reaction is when two hydrogen atoms combine to form a helium atom. During the process, a portion of the hydrogen's mass is converted into energy.
Thus, two hydrogen atoms fused to one helium molecule, hence option B is correct.

determine the velocity of a cart traveling at 135cm in 5.5s.
Answer: 0.245 m/s
Explanation:
So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s
Why does a DNA fingerprint require millions of copies of each DNA fragment
Answer:
Because it can identify a person.
A DNA fingerprint is a piece of DNA so distinct that it can prove a person's identity. These distinct areas can take on many different forms, but each form is unique to any one individual.
PCR allows the amplification of a single copy of DNA into millions of copies. However this technique requires that the DNA of interest already be of a known sequence in order to design primers that will specifically hybridize to the target DNA.
It is important as:
It's used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease.
