A student made a model of an onion skin cell she viewed using a microscope. The scale is 1:500.The students cell model has a length of 15cm. How many centimeters is the real cells length?
Answer:
Length of the real cells = 7500 cm
Explanation:
A scale model is a physical representation of an object that has the same aspects as that of the object.
A scale model can be used in fields like engineering, film making, salesmanship, etc
Length of the student's cell model = 15 cm
The scale is [tex]1:500[/tex]
So,
Length of the student's cell model / Length of the real cells = [tex]1:500[/tex]
15 / Length of the real cells = [tex]1:500[/tex]
Length of the real cells = 15 × 500 = 7500 cm
Answer:

define the general difference between an autotroph and a heterotroph
Answer:
Explanation:
If we break down the word autotroph, auto means “self” and troph means "feeding" or nourishment. However, when we break the word heterotroph, we get hetero- meaning other, and troph meaning feeders.
This is the critical difference between these two groups. Autotrophs synthesize or make their own food whereas, heterotrophs cannot make their own food thus have to rely on others by eating or absorbing others. For example, plants are autotrophs because they can make their own food using photosynthesis, whereas, humans are heterotrophs because we have to eat others to survive.
Answer:
autotrophs are organisms that can produce their own food from the substances around them using light or chemical energy
heterotrophs cannot synthesize their own food and rely on other organisms plants and animals for nutrition
Explanation:

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: Osmosis, because energy is being used to move molecules with the concentration gradient. Active transport, because energy is being used to move molecules against the concentration gradient. Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Answer:
Active transport, because energy is being used to move molecules against the concentration gradient.
Explanation:
This picture shows active transport. That just means that energy is being used (in this case, ATP) to move molecules against their gradient (meaning, from low to high concentration). Molecules "naturally" diffuse from high-->low concentration, so to move in the opposite direction requires energy input. You can tell this because there are only 2 molecules on the top side of the membrane, but on the bottom side there are 13.
Why not A: This is not necessarily water, as in osmosis, and it's not going with the gradient.
Why not C: This is not facilitated diffusion, because molecules are going against, not with, their concentration gradient.
The description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.
WHAT IS ACTIVE TRANSPORT:Active transport is a type of transport that requires the input of energy in form of ATP. This is because the movement of molecules is against a concentration gradient. According to the diagram in this question, molecules are being moved into the cell with an input of ATP (energy).Therefore, the description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of __
Answer:
The answer is 7.5 feet.
Explanation:
When a wave has a height of 5 feet and a wavelength of 15 feet then it has a wave base of 7.5 feet. Wave base is equal to the half of the wavelength so if you consider your wavelength to be 15 feet then it is divided into 2 that would give you answer of 7.5 feet.

A semipermeable membrane has a 2 percent salt solution on one side and a
15 percent salt solution on the other side. What will most likely occur?
A. Osmosis of water from a low concentration of salt to a high
concentration
B. Osmosis of water from a high concentration of salt to a low
concentration
c. Active transport of salt until all the salt is concentrated on one
side
D. Facilitated diffusion of salt until both concentrations are equal
Answer:
A
Explanation:
Water naturally travels from a low solute concentration to a high solute concentrated.
The correct answer is B. Osmosis of water from a high concentration of salt to a low concentration. This is due to the process of osmosis, which is the movement of water molecules from an area of low solute concentration to an area of high solute concentration.
What is the context of it ?In this case, the high salt concentration is on one side of the semipermeable membrane and the low salt concentration is on the other side. Therefore, water molecules will move from the side with a higher salt concentration to the side with a lower salt concentration, resulting in the osmosis of water from a high salt concentration to a low concentration.
The other options are incorrect because they do not accurately describe the process that occurs. Option A is incorrect because it states that osmosis will occur from low to high concentration, which is the opposite of what occurs in this situation.
Option C is incorrect because active transport requires energy and is used to move molecules against a concentration gradient, which is not happening here. Option D is incorrect because facilitated diffusion does not require energy and is used to move molecules down a concentration gradient, which is not happening here.

Answer:
C. Understand the process
Explanation:
When scientists create models of earthquakes, they are trying to learn more about them to try and keep people safe in the event that one does happen. It is practically impossible to change the location of an earthquake or stop it from occuring, since earthquakes are caused by the movement of massive continental plates. Scientists also definitely do not want to increase the waves formed in the process, as this would contribute to the damage. Therefore, the correct answer is choice C, understand the process. Hope this helps!
Scientists use models of earthquakes, so as to: C. understand the process.
What is an earthquake?An earthquake simply refers to a sudden, natural shaking of the ground, due to movements within the Earth's crust and upper mantle (lithosphere) which typically creates seismic waves.
In order to have a better understanding of the features of an earthquake and the processes that are associated with, scientists generally use models of earthquake.
In conclusion, earthquake models are simulations which can be used by scientists to better understand the process.

Answer:
Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:
Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.Hence, bat boxes at houses have a positive effect on the environment.

Why anaerobic respiration is rapid than aerobic respiration
Answer:
The amount of pressure that is released.
Explanations:
Aerobic respiration is known as a major advantage, base of the amount of energy it releases. Aerobic respiration releases more energy than anaerobic respiration, causing it to become more rapid.
Answer:
Anaerobic respiration is a shorter process than aerobic respiration so a complete cycle of anaerobic respiration is shorter than one of aerobic respiration.
Explanation:
Aerobic respiration involves three stages: glycolysis (the breakdown of glucose into pyruvate), the Krebs cycle (the breakdown of pyruvate into carbon dioxide and hydrogen), and the electron transport chain (hydrogen produced in the Krebs cycle bonding to oxygen to form water).
On the other hand, anaerobic respiration has fewer stages. Anaerobic means 'without oxygen', and so the process takes place without needing any oxygen. In anaerobic respiration, glucose is broken down into pyruvate, just like in aerobic respiration, however due to the lack of oxygen, that pyruvate is broken down into either lactic acid (e.g. in humans), or ethanol (e.g. in yeast). This process is called fermentation, and it doesn't take as long as the Krebs cycle and the electron transport chain, so that's why anaerobic respiration is more rapid than aerobic respiration.
