Why is geotropism important to plants?
Answer:
Geotropism guides plant roots to grown downward, or if growing horizontally in shallow topsoil, to occasionally branch and send some roots vertically downward. This creates structural anchorage and integrity of the plant, especially once upright stems and leaves occu
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.

What is the difference between cellular respiration and breathing?
Answer:
Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP - a molecule used to provide energy for chemical reactions.

Santos and Lüderitz are the same distance from the equator, and both cities are near the ocean. The air temperature in Lüderitz is colder than the air temperature in Santos. What causes the air temperature in these places to be different? Explain what causes the difference as completely as you can.
Answer:
The currents cause the air to be different.
Explanation:
If you look at a current map, you'll see that there is a warm current near Sanots and a cold one near Lüderitz. Therefore, the temperature of Sanots must be higher and the temperature of Lüdertizt will be colder.

What do you think could make the magnetic force produced by the launcher system so much stronger in the Wednesday launch than in the Tuesday launch, even though the spacecraft was moved the same distance closer?
If I were you only answer this if you do amplify
Answer:Magnetic forces are stronger closer to magnets. The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.

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.

How was osmosis used to stop Clark’s seizures?
Answer:
after Clark was treated with a hypertonic solution? increased Na concentration in matrix of brain caused water from blood to move in to the brain which increased the matrix pressure. Pressure caused the neuron firing rate to increase which increased the likelihood of seizures.
Explanation:
hope this helps :)
The osmosis used to stop Clark’s seizures should be considered as the hypertonic solution.
Usage for stopping the Clark’s seizures:After clark it was treated with the hypertonic solution.

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.
Which of the following is a disadvantage to using chlorine for disinfection of water?
Answer:
Damage our health.
Explanation:
The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.
Answer:
Chlorine reacts with organic compounds.
Explanation:
Chlorine reacts with organic matter to create chlorination byproducts which often change the overall chemical properties of water.
