Which is NOT an example of a renewable energy source?
O Coal
O Wind
O Water
O Sun
Please help ASAP
Answers
Answer:
coal
Explanation:
wind and water never end so they're renewable and the sun like ofc also never ends
but you can run out of coal
Answer:
Coal
Explanation:
A renewable energy source is a source of energy that is not likely to run out within our lifetimes. The wind will never go away. Neither will the Sun. Although we know that the Sun is going to explode, since it is a star, it is not likely that it will happen in our lifetimes. Water is also not likely to run out completely within our lifetimes. However, coal on the other hand will run out some day; it takes millions of years to make coal, and people are using it faster than it can replenish itself.
A good way to remember which energy source is renewable and which is not is to look at how much it pollutes. Fossil Fuels such as Coal, Oil, and Natural Gas pollute a lot, and they are all nonrenewable energy sources. On the other hand, clean energy sources such as solar power, hydropower (water power), and wind power do not pollute as much, and they are all renewable resources. (Please note that this relationship is not causation, but rather correlation. The amount of pollution an energy source emits does not cause it's renewability.)

The first stage of the cell cycle during which the cell matures and prepares to divide and copies
its DNA; The stage the cell stays in the most?
Answers
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.
Therefore, The first stage and the stage the cell stays in most is Interphase.

Normal Height:
0%
Hybrid
Corn
h
Short Height: 0%
Answers
Answer:
See the answer below
Explanation:
Normal height - H
Short height - h
Heterozygous - Hh
A cross involving heterozygotes would be Hh x Hh
Hh x Hh
HH Hh Hh hh
Since H is dominant over h;
HH and Hh would produce normal height phenotypes.
hh will produce a short height phenotype.
Thus;
Probability of normal height phenotype resulting from the cross = 3/4 or 75%
Probability of short height phenotype resulting from the cross = 1/4 or 25%

Nanotechnology is a field of producing materials and devices from atoms and molecules.
Explanation:
Nanotechnology is a field that concerned with producing materials and devices from atoms and molecules. A nanometer is one-billionth of a meter in size. Nanotechnology can be used to “recognize” the cells of interest which allows associated drugs to reach diseased tissue without damaging healthy cells. Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.

Perhaps no one cares more about being able to see in the ocean than do divers. The Cayman Islands, Bonaire and the Bahamas are all popular dive destinations due to both submarine features, such as coral reefs, and water clarity. Under the best of circumstances, visibility in these locations is between 50 ft (15 m) to 150 ft (45 m). Based on this, and what you have learned about sound, write a paragraph describing those ways in which humans and marine organisms use sound for some underwater tasks and light for others.
Answers
Answer:
Humans and marine organisms use sound finding depth of the ocean and objects.
Explanation:
Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.
