Explanation:
The image on the left shows a normal red blood cell, and the image on the right shows a cell that has been put into a new solution. The circles represent the salt in the solutions.
Which statement describes the motion of the water molecules in this situation?
The water molecules move by active transport into the cell from low water concentration to high water concentration.
The water molecules move by osmosis into the cell from low water concentration to high water concentration.
The water molecules move by osmosis into the cell from high water concentration to low water concentration.

Answers
Answer:
C. The water molecules move by osmosis into the cell from low water concentration to high water concentration.
Explanation:
The environment in picture 2 (the solution) has less solute (salt) and more water than in picture 1. Since the cell was isotonic (the same concentration of solute exists inside and outside the cell), if the cell were to be placed in an environment with more water, like in picture 2, water would diffuse through osmosis INTO the cell in order to maintain the same concentration of solute by diluting the solute present in the cell.
Mia looked at a graph showing average global temperatures. She noticed that the average temperatures have risen abruptly over the past several decades. This indicates that global warming is occurring at a fast rate. What additional pieces of evidence do scientists use to support the idea that global warming is happening?
Question options:
the amount of greenhouse gases leaving the atmosphere and increases in amounts of sea ice
the greenhouse effect and reductions in sea levels
greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels
ocean temperature changes, greenhouse gases concentrations, and harmful emissions reductions
Answers
The idea of global warming is happening is supported by increasing greenhouse gases concentrations, decreases in amounts of sea ice, and increases in sea levels.
Global warming is purported to be due to the inability of reflected solar radiation to travel back to space as a result of greenhouse gases forming a layer of blanket over the atmosphere.
Thus, an increase in the concentration of greenhouse gases correlating with an increase in global temperature is one piece of evidence used to support the idea of global warming.
Also, it is logical that increased global temperature will lead to the melting of sea ice and the resulting water will cause a rise in the levels of seas. The existence of these phenomena reinforces the idea that global warming is actually a thing.

What is used to measure the energy in a chemical reaction?
Answers
I'm pretty sure it's a calorimeter.
Answer:
calorimeter
Explanation:
calorimeter
A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.
