<span>Each of the protein chains are conjugated to a nonprotein heme group.Hemoglobin is the protein that's made of the four polypeptide chains. Each of these chains contains a heme group. Red blood cells are primary players in the oxygen hauling, and they wouldn't be able to do their job if it the weren't for a special molecule called the heme.</span>

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.

Vegetable shortening is a food product rich in trans fatty acids. It is produced by converting several cis double bonds totransd
liraira [26]

Answer:

Partial hydrogenation

Explanation:

Vegetable oils naturally contain cis fatty acids. These fatty acids have double bonds and the two H atoms are on the same side of bond, producing a kink in  the structure.

Cis fatty acids are converted into trans fatty acids by the process of partial hydrogenation or vegetable shortening. Hydrogen is added to convert some of the double bonds into single bonds but all double bonds are not removed. However, the cis double bonds end up getting converted to trans double bonds. H atoms are now on the opposite sides of the double bond. This arrangement makes the kink disappear from the structure hence trans fat is structurally similar to saturated animal fat. It increases the longevity of fats and makes it solid at room temperature but also has many side effects like increasing bad LDL cholesterol in blood.

IrinaK [193]

Answer:

D) How do living things get energy?

G) How are living things related?

F) Where do living things make their home?

Explanation:

Different types of organisms are present on this Earth which interact with both abiotic and biotic factors and influence the nature of the environment. So there is a need to study the living organisms in which the first thing is to arrange the living organism by a process called classification.

The questions that are necessary to classify the organisms include related to the mode of energy or nutrition, the relation between various species at the morphological and molecular level, the habitat. The relationship between the organism is a very important aspect as it makes the classification easily according to their similarities and dissimilarities.

Thus, the selected options are the correct answer.
