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.

Which cells for visual processing are located closest to the back of the retina?

Brrunno [24]

Answer:

Rods and cones

Explanation:

The retina contains the light sensitive cells, the cones and rods. It is here that an image is formed. Rods contain the photochemical pigment rhodopsin for dim light vision. Cones contain the photochemical pigment iodopsin for bright light and colour vision.

what is the purpose of a lysosome? it is the control center of the cell and contains DNA it is used for movement it breaks glyco

olasank [31]

Answer:

it breaks glycogen into glucose

Explanation:

Lysosome is an organelle in the cells that is responsible for the production of digestive enzymes and thereby breaks down glycogen to glucose.

Lysosome is membrane bound organelle.
It is responsible for the secretion of digestive enzymes and breaking down of dead cells.

The nucleus is the control center of the cell and it contains the DNA.

Proteins are not created in the lysosome and they are not responsible for the movement of the cell mass.

$\large{ \boxed{ \bf{ \color{skyblue}{The \: correct \: question:}}}}$

Q. In an ________ solution, red blood cells ________. Group of answer choices:

Hyposmotic, lose water and shrivel
Isomotic, have a normal shape ✔️
Isosmotic, swell and may burst
Hyperosmotic, have a normal shape
Isosmotic, lose water and shrivel

$\large{ \boxed{ \bf{ \color{violet}{The \: correct \: answer:}}}}$

In an <u>isosmotic</u> solution, red blood cells <u>have</u><u> </u><u>normal</u><u> </u><u>shape</u><u>.</u>

Option B

<h3><u>Explanation:-</u></h3>

Osmosis : The movement of the <u>solvent</u> or <u>water</u> molecules from a solution of their higher concentration to a solution of lower concentration through a <u>semipermeable membrane.</u>

❍ Depending upon the <u>osmotic concentration,</u> There are three types of solution and their result when cell is keot inside them:

Hyposmotic (Water enters, Swells up)
Isosmotic(Equal flow, No change)
Hyperosmotic(Water comes out, shrinkage)
