In addition to observable traits, scientists use to classify living things

In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.

In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.

Provide an adaptive and a nonadaptive hypothesis for the evolutionary loss of useless organs, such as eyes in many cave-dwelling

Zepler [3.9K]

In order to be able to Provide an adaptive and a non-adaptive hypothesis, the following is required

<h3>What is adaptation?</h3>

It refers to a trait or an integrated set of traits that increases the fitness of an organism. It is the process of improving the fit of phenotype to environment through natural selection.

<h3>What is non adaptation?</h3>

it refers to those traits that do not result in the better adaptation of the organism to its environment, and does not increase the genetic fitness of the organism.

Let us take the case of vain organs. There may be a metabolic value to constructing a vain organ, and subsequently the humans who have misplaced that organ might also have a selective advantage. Also, if the organ is useless, the mutations that disrupt the improvement of that organ would be evolutionarily neutral, and may want to unfold to fixation via genetic drift.

So an adaptive hypothesis as to why an organism may lose useless organs is energy trade offs. The organism may additionally be losing energy in growing and retaining a vain organ, whilst this strength can be higher used someplace else. So an organism that lives in a darkish cave might also sooner or later lose its eyes considering eyes are of no use inside a darkish cave.

A non adaptive hypothesis for the evolutionary loss of organs can be random mutation. If a random mutation occurs that causes an organism to lose its eyes, in a dark cave where it does not use its eyes anyway, it could still survive, reproduce and pass that mutation down.

(oxygen, electron transport chain, chemiosmosis, NADPH)

Vaselesa [24]

Hai there :3 I'm planning to study chemical engineering.

Question related to Biochemistry (Photosynthesis & Cellular Respiration)

1. Chemiosmosis. In the process of chemiosmosis, specific enzymes (such as ATP synthase) create ATP. Hydrogen ions go from a higher proton concentration to a lower one, which is why it's called chemio"osmosis"

2. Electron Transport Chain (ETC). The name says it all. Simply explained, electrons are transported and transferred in the mitochondrial membrane.

3. Oxygen. O2, the diatomic molecule, is essential in respiration. In the final stage of respiration, at the near end of the electron transport chain, oxygen accepts protons to become water. Cells use O2 during oxidative phosphorylation.

4. NADPH. I remember learning what this acronym means by heart. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen. NADPH is essential in photosynthesis as a typical coenzyme in the reduction of chemical reactions.
