A seismograph station is located several thousand kilometers from an earthquake’s epicenter.
Explain the order that the S and P waves will arrive at the station.
By using the characteristics of the S and P waves explain why they arrive in the order they do.
Answer:
The P waves will arrive at the station first because they travel the fastest at an average of 6.1 km/s. The S waves will arrive second, traveling slower at approximately 4.1 km/s. The two different waves would have arrived 3 minutes apart, based on the S-P Wave Interval Chart.

Explanation:
You want to alter this model so it also shows the flow of energy through the biosphere. To start, you draw a sun. Then, you draw arrows from the sun to the trees and the photosynthetic algae, which are examples of . From there, arrows would be drawn to the moose and the fish, which are . Finally, you would draw arrows connecting groups to , which are represented by microbes responsible for decomposition on this model.
Answer:
The correct answer is :
1. Autotrophs
2. Heterotrophs
3. Saprophytes
Explanation:
In a flow of energy through a biosphere, organisms that trap sunlight for producing their energy on their own known as autotrophs such as plants and photosynthetic algae. These organisms are able to produce their energy and food on their own.
The moose and the fish are the organisms, depends on another organism for their food which means they are heterotrophs and these organisms only get 10% of the energy of what they depend on.
Plants and animals when dies or dead organic matter are decomposed by various microorganisms known as saprophytes to get their energy.

Which of the following is NOT a source of nitrogen that is available to plants?
Answer:
I CANT SEE THE FOLLOWING BUT I WILL EXPLAIN.
Explanation:
Plants usually absorb nitrogen from NO3- and NH4+
Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.
How does plants take nitrogen?Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.
Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.
Therefore, the correct option is D.

TRUE OR FALSE: The molarity of a flaccid plant is equal to the molarity of the solution. The molarity of a turgid plant is greater than the molarity of the solution. The solute potential of a turgid plant is lower than the solute potential of the solution. The molarity of an plasmolyzed plant cell is greater than the molarity of the solution.
Answer:
1. The first statement is true because water movement takes place until it reaches an equilibrium.
2. The second statement is false because the concentration inside the cell will be greater until water moves inside the cell.
3. The third statement is true because solute concentration is high outside.
4. The fourth statement is true because it loses water in a hypertonic solution.

Carbohydrates contain carbon, hydrogen, and oxygen. When you eat foods that contain carbohydrates, your body uses a complex process, cellular respiration, to turn the carbohydrates into useful energy. Which carbohydrate is converted into ATP to provide energy for the cell in humans?
Answer:
Answer is Glucose because First of all lipids and lipase are not carbohydrates so they cant be the answer and the cellulose is very complex carbohydrate so it is first broken down into monosaccharides then we could use it to make ATP. Whereas, Glucose is a monosaccharide which is the simplest form of carbohydrate so it is converted into ATP to provide energy

Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells
lung cells
skin cells
heart cells
Answer:
skin cells.
Explanation:
for connexus friends
The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.
The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.
Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.
Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

If the function of an aquaporin is inhibited, how would the transport of water into the cell be affected? (3 points)
A. Water molecules will no longer be able to cross the cell membrane.
B. Water molecules will move across the cell membrane at a much slower rate.
C. Water molecules will only be able to cross the cell membrane by active
transport
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
Answer:
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.
If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.
What is the function of Aquaporin?The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.
Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.
If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.
Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

Answer:
Herbivore
Explanation:
The grasshopper eats grass and does not seem to eat anything else in the food web, so it is a herbivore. Herbivores are organisms that eat plants, and since the grasshopper furfills this definition, therefore it is a herbivore. It is not a carnivore because carnivores do not eat grass. It is not a decomposer because it does not break down dead material. It is not an omnivore because it does not eat both plants and animals.
What is the difference between diffusion and facilitate diffusion
Answer:
Diffusion is the passage of molecules from a high-concentration region of the molecule to a lower-concentration area of the molecule.
Facilitated diffusion is the passage of a molecule with the assistance of a protein channel or carrier from a region of high concentration to an area of lower concentration.
