In the normal course of evolution and adaptation, what is the most likely way for wings to develop in a tetrapod (four-limbed or

ganism)?
A major mutation will produce new limbs, called wings, with a skeletal structure suited to flight. If this does not happen, flight cannot be achieved.

The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.

A new, third pair of limbs will form. Unlike the other four limbs, these wings will have a lightweight skeletal structure that is designed "from scratch" and is perfectly suited for supporting flight.

The forelimbs (or hind limbs) will be used for the new purpose of flight. Natural selection will totally rearrange the elements of the skeleton to perfect the limb for its new function as a wing.

The correct option is this: The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight.  

Adaptation refers to the physical or behavioral traits that an organism develop in order to enhance its suitability to its environment. Evolution on the other hand is always brought about by natural selection; organisms that are well adapted to their environments are naturally selected to survive, reproduce and pass their beneficial traits to their offspring. This is a gradual process that occurs over a long period of time.  

For wings to develop in a four limbed organism, the organism has to start using the hind or the fore limbs for flight (New adaptive behavior). The genes that support this new behavior will be passed to its offspring and subsequent generations over a long period of time, until the wings are perfectly suited for flight.

Sedaia [141]

Answer:

a. Always independently stable. Domain

b. Retains native structure even when separated from the rest of the protein. Domain

c. β Barrel. Motif

d. Calcium-binding segments of calmodulin. Motif

e. An advantageous folding pattern composed of two or more secondary structure elements. Domain

f. Sometimes independently stable. Motif

Explanation:  

a. Protein domains are evolutionary conserved and stable 3D structures formed by a series of amino acids joined by peptide bonds.

b. Domains are stable because they conserve their tridimensional structure in physiological conditions even if they are separated of the rest of the protein.

c. The ß-barrel motif is a type of motif localized in single-stranded DNA viruses.

d. Calmodulin is a protein that contains calcium-binding motifs that enable to sense intracellular calcium levels.

e. Domain folding patterns are critical transitional states that allow the proteins their interaction with specific ligands in different physiological conditions.

f. Motifs are sometimes independently stable, but due to their short length (3-15 amino acids), protein motifs are generally unstable in different conditions.

Greenhouse gases absorb radiation from the and re-radiate it back toward the
Flauer [41]

Answer:

Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.

Explanation:

Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.

The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.
