Answer:
Mass the bag before and after its exposure to the solution. If diffusion occured, then there should be an increase in the bag's mass.
Explanation:
please mark brainlyest
To modify the experiment to collect quantitative data showing that water diffused into the dialysis bag, you could measure the change in the weight of the dialysis bag before and after the experiment.
Here's how you can do it: Prepare the dialysis bag and fill it with a known volume of a solution. For example, you could fill the bag with 100 mL of a sugar solution. Weigh the dialysis bag using a balance before placing it in the beaker with water.
Place the filled dialysis bag into a beaker of pure water. Make sure the dialysis bag is fully submerged in the water. Allow the setup to stand for a specific amount of time (e.g., 1 hour) to allow water to diffuse into the dialysis bag.
After the specified time, carefully remove the dialysis bag from the beaker of water and gently pat it dry with a paper towel to remove any excess water on the outside. Weigh the dialysis bag again using the same balance.
Calculate the change in weight of the dialysis bag by subtracting the initial weight from the final weight. The weight difference represents the amount of water that has diffused into the dialysis bag.

Organism X and Y live in the same environment. Organism X contracts a bacterial infection that causes its body temperature to rise to 60°C. How will this change in temperature affect enzyme activity in both organisms?
It will decrease enzyme activity in both organism X and organism Y.
It will increase enzyme activity in organism X and decrease enzyme activity in organism Y.
An increase in temperature above the optimal range will increase the reaction rate.
An increase in temperature will denature the enzyme causing a reduction in the reaction rate.
Answer:
an increase in temp will denature the enzyme causing a reduction in the reaction rate

What questions do environmental biologists ask about what they study?
Answer:
Ecology is the study of the interactions of living things with their environment. Ecologists ask questions across four levels of biological organization—organismal, population, community, and ecosystem. At the organismal level, ecologists study individual organisms and how they interact with their environments.

The primary gases of the atmosphere are blank
Answer:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.

1. Explain the relationship between heat and
thermal energy.
Answer:
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).
Write down the tRNA anti-codons that pair with the mRNA strand.
Note: Please use capital letters, and follow this format: A-A-A-A-A-A-A-A
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
what plate movements and earth features lead to the Earth Quake Prince William sound? (the Alaska Earthquake)
According to "M9.2 Alaska Earthquake and Tsunami of March 27, 1964",
On March 27, 1964 at 5:36pm local time (March 28 at 3:36 UTC) an earthquake of magnitude 9.2 occurred in the Prince William Sound region of Alaska. The earthquake rupture started approximately 25 km beneath the surface, with its epicenter about 6 miles (10 km) east of the mouth of College Fiord, 56 miles (90 km) west of Valdez and 75 miles (120 km) east of Anchorage. The earthquake lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history. It is also the second largest earthquake ever recorded, next to the M9.5 earthquake in Chile in 1960.
The map shows the epicenter of the 1964 Alaska Earthquake (red star), caused when the Pacific Plate lurched northward underneath the North American Plate.
Answer:Pacific Plate
2. Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.
