What would happen if a cell membrane let too much water into a cell?
Answer:
Animal Cell
When water moves into an animal cell (e.g. a red blood cell), the cell membrane stretches and the cell gets bigger. If this continues, the cell membrane will burst – this is called lysis.Plant Cell
When too much water moves out of a plant cell the cell contents shrink. This pulls the cell membrane away from the cell wall. A plasmolyzed cell is unlikely to survive.Is there a relationship between cohesion and volume?

A student fills four containers with 20 ml of water and places them in four different locations.
One is placed in a sunny window, one is placed underneath a heat lamp, one is placed on a
student desk, and another is placed in a dark cabinet. The student plans to collect evaporation
data over a period of one week. Which prediction will best match the actual results?
Answer:
a heat lamp
Explanation:
Answer:
The one under the heat lamp is most effective
Explanation:
The heat is making the water warm and will soon evaporate
Write a description that explains how the digestive, circulatory, and excretory systems WORK TOGETHER in order to deliver very important materials to the cells and dispose of waste products from the cells! Try to include as many details as possible - What is the blood carrying? Where is it going? How does it get there? What does it get rid of and how?
Answer:
At the end of each organ system you will need to make a summary of that ... So how does the food we eat eventually get to our cells in a small enough form ... The circulatory system is responsible for transporting blood with oxygen (O2) ... the digestive system to the cells in the body and remove waste products to be excreted.
hope this helps!

this is my third time asking this,,, HELPPPPPP PLZZZz i'll mark brainliest! Infrared (IR) and ultraviolet (UV) light. But above 29°C, the coating on the glass undergoes a chemical change, causing it to block IR light. What happens to the IR light?
Answer:it would not cause any effect because its blocking it. Basically u could say that what would happen is that no effect was happening cuz of the blocking.
Explanation:
Write a summary of some key ideas about chemical reactions.
Please!
I have to pass science to be able to get my nails done professionally!!!
I WILL MARK BRAINLIEST!!!!
Answer:
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Reactants are the starting materials, while products are the end result of the reaction. All chemical reactions are accompanied by a change in entropy.
In general, chemical reactions can be classified as either redox reactions or non-redox reactions. In redox reactions, there is a transfer of electrons between reactants. In non-redox reactions, there is no electron transfer. All exothermic reactions are redox reactions, while endothermic reactions may be either redox or non-redox.

Hope this helps!

Elements in the same period are similar in that
same number of valence electrons of same number of energy shells
Answer: I believe this is the answer: The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Good luck on assignment! :)
Answer: The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.
Explanation: :)
In a __________________ reaction, elements are not changed, just rearranged. Small amounts of energy take place.
a. Endothermic
b. Exothermic
c. Nuclear
d. Chemical

Mrs. Hernandez brought her pet bird to school one day to find out what her students understood about forces. As the bird rested on a perch, Mrs. Hernandez asked her students to describe any forces acting on the bird. This is what some of her students said:
Bob: The only force acting on the bird is gravity.
Chelle: The only force acting on the bird is air pressure.
Fred: There are no forces acting on the bird because the perch stops any forces from acting on it.
Omar: There are many forces acting on the bird. The bird is held in place by the force of the branch.
Katrina: The force of gravity pulls down on the bird while the branch pushes up to support the bird.
Which student do you most agree with?
Explain your thinking. What reasoning did you use to decide what forces were acting on the bird? (WILL GIVE BRAINLIEST!!!)
What is the difference between a chemical change and a physical change?
A. A physical change forms a new substance with different properties. While in a chemical change, the materials remain the same.
B. A chemical change forms a new substance with different properties. While in a physical change, the molecules remain the same.
C. A chemical change forms a different shape, such as by bending, folding, or melting, but does not form a new substance with different properties.
Answer:
A
Explanation:
because chemical change is permanet.
