Based on the demonstration and your microscopic investigation, which of the three solutions is hypotonic to the red blood cells?
r-ruslan [8.4K]

You have given no demonstration based on your microscopic investigation so I cant tell you the answer to the question. I will try to help you by elaborating how to decipher..

Three terms hypotonic, hypertonic and isotonic are used when referring to two solutions separated by a selectively permeable membrane.

The hypertonic solution has a great concentration of OAS than the solution on the other side of the membrane. It is described, therefore, as having a great osmolarity. The hypotonic solution has a lower concentration of OAS, or osmolarity, than the solution on the other side of the membrane. When the two solutions are at an equilibrium, the concentration of OAS being equal on both sides of the membrane, the osmolarities are equal and are said to be isotonic.

The net flow of water is from the hypotonic to the hypertonic solution. When the solutions are isotonic, there is no net flow of water across the membrane.

If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells.

So, look at the information and data you have on your microscopic investigation and use these guidelines to tell you which is which.

What is happening to the amount of carbon in the living things in a biodome
Rzqust [24]

Answer:

Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall. How do they figure it out? They get evidence from the sim and from video of an experiment to determine which organisms do cellular respiration.

Explanation:

Hope this helped you :D

What is the differences between cellular respiration and respiration
3241004551 [841]

Think of respiration as ‘cellular respiration,’ which is the process by which the body extracts energy from glucose molecules. Breathing is the mechanism of the lungs that brings oxygen into the body and expels carbon dioxide

Respiration is a vital way for the cells of plants and animals to obtain and utilize energy. Without this energy, cells in the bodies of plants and animals would fail to function and will eventually break down and die. The breaking down of sugar into energy and storing it in ATP is the key to the survival of living organisms.

The formation of ATP involves two different processes, cellular respiration and fermentation. The reactions to these processes are controlled by enzymes and involve the loss and gain of electrons.

Cellular respiration takes place in the cells of organisms using metabolic reactions and processes to convert biochemical energy from the nutrients they absorbed into ATP or adenosine triphosphate and to release waste products.

The energy derived from nutrients like sugar, amino and fatty acids, an electron acceptor which can be oxygen (used by aerobic organisms) or other inorganic donors like sulfur, metal ions, methane, or hydrogen (used by anaerobic organisms) are stored in ATP and used for biosynthesis, locomotion and to transport molecules in cell membranes.

Cellular respiration can be aerobic or anaerobic. Aerobic respiration requires oxygen to generate ATP and plants and animals use this in utilizing the energy they received.
