If Earth did not rotate and there were no Coriolis effect, surface wind
direction would primarily be *
From east to west
From west to east
From the poles to the equator
O From the equator to the poles
If Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.
What do you mean by the Coriolis effect?
The Coriolis effect may be defined as making things traveling long distances around the Earth appear to move at a curve as opposed to a straight line.
The Coriolis effect is responsible for the blowing of winds from the east to the west. It makes the wind system twist counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Without its presence, the direction of wind gets opposed.
Therefore, if Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.

What is gained from each part of aerobic respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
Hope this helps..How reintroduction of the sea otter populations impacts the health of the kelp forest ecosystem describe the impact on at least 3 other l species within the kelp forest
Answer:
Sea otters encourage the growth of giant kelp forests as they control sea Urchin populations. Otters are a keystone predator. Kelp forests are curcial to many many many species of animals. Sea lions and seals feed on the fish there, many types of fish are found there crucial to fisherman such as all types of rock fish. Crabs, jelly fish, sea stars, anemones, and other small fish rely of these forests so it will greatly impact their population and over all health and the health of the ocean if there is a sea urchin population control.

Neurons are cells of the nervous system. As part of its normal function, a
neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. Which statement describes the role of energy in this process?
a. The process releases energy that is used to make ATP.
b. The process releases energy in the form of heat.
c. The process requires energy that is provided by the sodium and potassium ions.
d. The process requires energy that is provided by ATP.
Thank you! :)
Answer:
D. The process requires energy that is provided by ATP.
Explanation:
Neurons use a pump called the sodium-potassium pump, which normally pumps sodium ions out of the cell and pumps potassium ions into the cell.
This pump goes against the concentration gradient to create the resting membrane potential.
Since the pump goes against the concentration gradient, it requires energy, because it is not passive diffusion.
So, D is the correct answer, as the process requires ATP energy.
Neurons are cells of the nervous system. As part of its normal function, a
neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. The process requires energy that is provided by ATP. The correct answer is option D.
What is the role of sodium potassium pump ?The role of the sodium potassium pump is the muscle contraction and the nerve impulse. In exchange of 2 potassium ions is the displacement of 3 sodium ion and this exchange is against the concentration gradient thus requires the molecule of ATP for the transfer of the ions.
The Na+/K+-pump an active transporter uses ATP hydrolysis in energy source to move ions across the neuronal membrane down their concentration gradients and assigned specific functions associated with the generation of the action potential as well as with the maintenance of other active transport.

Give two examples of what a living thing can do once it has converted the energy from food into usable forms of energy.
Answer:
When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.
The chemical energy, which is needed by the organisms comes from the food. Food comprises organic molecules, which captivates energy in their chemical bonds.
• The organisms generally use two kinds of molecules for chemical energy, ATP and glucose.
• Both the molecules are utilized as fuels all through the living world.
• Energy is the tendency to perform an activity. It is required by all the living species and every living cell to perform the processes of life.
• Energy in the form of chemical energy is utilized to dissociate and form the molecules, and to transport several molecules through the cell membranes.
• The organisms primarily use ATP and glucose for energy.
Thus, the form of energy required by the living species to perform the essential activities of life is obtained from food.

there are no answers, you can put them in the comments
Explanation:
Describe fully what will occur if a plant cell is placed in a solution that has a higher water potential than the cell. Use the following terms in your answer.cell wall, freely permeable, partially permeable, cell surface membrane, vacuole, tonoplast, cytoplasm, solute potential, pressure potential, water potential, turgid, osmosis, protoplast, equilibrium
Answer:
tortinos
Explanation:
hot pizza rolls
When the plant is placed in the higher water potential, the water will diffuse from the higher water potential to the lower water potential and make the plant cell turgid. As a result, the plant cell will swell.
What is the plant cell in a hypotonic solution?When a plant is placed in a hypotonic solution, that means the plant cell has less water potential than the outer side, and as a result, the water will flow from a higher water potential to a lower one. The plant cell membrane is partially permeable, and water will diffuse from the outer to the inner, causing the cell to exert more pressure on the cell wall and swell.
The vacuole will swell too in such a case, and the movement of water is called osmosis. The hypotonic solution has less solute potential, and the flow of water will continue until equilibrium is maintained.
Hence, this is the osmosis process, where the water will flow freely from the outside to the inside of the cell cytoplasm and make the cell turgid.

Why is it an important property for water to be less dense as a solid?
Answer:
Water has a unique density. It is less dense as a solid than it is as a liquid, which is why ice floats on top of liquid water.
Explanation:
Answer: Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water. With most other liquids, solidification when the temperature drops includes the lowering of kinetic energy between molecules, allowing them to pack even more tightly than in liquid form and giving the solid a greater density than the liquid.
The low density of ice, an anomaly, causes it to float at the surface of liquid water, such as an iceberg or the ice cubes in a glass of water. In lakes and ponds, ice forms on the surface of the water creating an insulating barrier that protects the animals and plant life in the pond from freezing. Without this layer of insulating ice, plants and animals living in the pond would freeze in the solid block of ice and could not survive. The detrimental effect of freezing on living organisms is caused by the expansion of ice relative to liquid water. The ice crystals that form upon freezing rupture the delicate membranes essential for the function of living cells, irreversibly damaging them. Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol.

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?
Plant cells will lose water due to osmosis.
Plant cells will gain water due to osmosis.
Plant cells will use the salt to grow taller.
There would be no impact.
Answer:
Plant cells will lose water due to osmosis
Explanation:
Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.
What is the relationship between genes DNA and proteins
Answer:
Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.
Hopefully, this answer helped! :D
Answer:
Most genes contain the information require to make proteins. The type of RNA that contains the information needed to make protein is called a messenger RNA or mRNA and it carries the message from the DNA out of the nucleus into the cytoplasm
