1. Suppose you go to the beach in the morning on a sunny summer day. Explain the rate at which thermal energy is absorbed by the water, sand, and air during the day.
2. Explain why the flow of energy between air and sand is different than that between air and water as thermal energy is absorbed from day to night.
3. As the Sun begins to set, predict the effect on the rate at which the air, water, and sand cool
4. Explain why the flow of energy between air and sand is different than that between air and water as thermal energy is RELEASED.
Answer:
1. During the day, the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well. However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean.
2.The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This can be compared to a blacktop road. During the day, the blacktop road heats up and becomes very hot to walk on. At night, however, the blacktop has given up the added heat and is cool to the touch. The ocean, however, is able to hold onto this heat after the sun sets and not lose it as easily. This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
3. The sand should both heat and cool faster than the water. This is because water has a higher specific heat ca- pacity than sand – meaning that it takes a lot of heat, or energy, to raise the temperature of water one degree, whereas it takes comparatively little energy to change the temperature of sand by one degree.
4.
Based on heat flow, land and sea breezes occur due to differences in the heat capacities of air, land and sea
What is thermal energy?Thermal energy is the energy due to temperature difference between two bodies.
Thermal energy or heat flows from hotter to colder bodies.
The flow of thermal energy between air, land and sea results in land and sea breezes.
On a sunny beach, the thermal energy absorbed by the water sand and air.
Water absorbs the most heat due its high heat capacity, while the air gets heated up easiest due to its low heat capacity.
The sand absorbs heat faster than the water and feels hot when stepped on.
As the land is heated faster than oceans, air over land is warmer than air over the water, thus, warm from land rises and is replaced by cold air from the ocean.
As the sun sets, due to the differences in their heat capacities, the air loses heat fastest, then followed by land while the ocean loses the least heat.
As the land loses heat faster than oceans, air over land is colder than air over the water, thus, cold from land replaces warm air from the ocean as it rises.

plz help
Answer:
Hello! Sorry I am late! Here is my best answer below!
Temperature depends on the tilt of earth. The closer the earth is to the sun the warmer it gets. If the sun is not pointing at the place you live in the earth the temperature where you are will be colder. If the sun is pointing at the place you are the temperature will be warm. In conclusion, the temperature just depends on the tilt of earth towards or away from the sun.
Some more information:
At night you may discover that it is much colder than during the day. This is because the sun is not pointing at that half of the earth.

what species of organism does the gene donor cell belong to?
Answer:
Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing into two daughter cells. The daughter cells that result from this division are genetically identical to each other and to the original parent cell. Thus, over time, asexual reproduction in bacteria can lead to a population of hundreds of thousands of cells, all of which are genetically identical to a lone original parent cell.
Given their asexual method of reproduction, it is tempting to think that bacteria are sorely lacking in genetic variation, but this is not the case. Prokaryotic cells have developed a number of methods for recombining their genetic material, which, in turn, contributes to their genetic diversity. The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. However, not all types of bacterial cells are capable of engaging in all three processes.

Q7. After exposure to a bioaccumulating toxin for long period of time, which type of organism would you expect
to have the highest toxin concentration?
O Fish
Zooplankton
Pitoplankton
All these would have about the same toxin concentration,
Answer: o fish
Explanation:
They have to consume more so that means the more the fish eats the more toxins its holding
After exposure to a bioaccumulating toxin for long period of time, fish will have the highest toxin concentration. The correct option is C.
What is bioaccumulation?Bioaccumulation occurs in a single species over the duration of its life, causing a greater concentration in older people.
Bioaccumulation is the procedure by which chemicals accumulate in a life form when the percentage of consumption exceeds the frequency of excretion.
Chemicals enter the body through exposure to the abiotic environment or through dietary intake.
When toxins are soaked up faster than the body can eliminate them, the organism is at danger of permanent poisoning.
Even if the environment does not contain a high concentration of toxin, accumulation through the food chain can be disastrous for organisms.
Thus, the correct option is C.
