Monosaccharides can be grouped as aldehydes and kefone groups,what is their difference and similarities and list four examples f

Lady bird [3.3K]

Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Which of the following events can result in inheritable genetic variations in organisms

Svetlanka [38]

The right answer is B.

The answer B is the only proposition which specified at which stage the event must occur, in fact, the meiosis.

Meiosis is a characteristic division of reproductive cells that can generate gametes to form new species (desendence). So if a mutation occurs at this time (such as recombinations) it will inevitably be inherited.

Which phrase best describes the property of selective permeability?

belka [17]

Answer:

some molecules pass

Explanation:

The ability of a membrane to pass or not to pass a substance is its permeability (permeability).

Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.

The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.

which is an example of biodiversity 900000 fires, deforestation, thousands of species carbon dioxide?

stira [4]

Answer:

Thousands of species is an example of biodiversity.

Explanation:

Biodiversity is the short term for biological diversity which was coined by E.O. Wilson. Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth. It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.

The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive. If they are overused or misused, the entire food chain would perish.
