How the adaptations of chameleons came about through gradual evolution ? NEED HELP ASAP

1 answer:

7 0

Chameleons, those shade-shifting, intricately camouflaged lizards that can change color in response to environmental or behavioral influences. Since the oldest lineages of chameleons are all from Madagascar, scientists believe they evolved on the island and spread out from there. As far as paleontologists can tell, the first chameleons evolved shortly after the extinction of dinosaurs 65 million years ago. Unlike other animals that change color, such as the squid and octopus, chameleons do not modify their hues by accumulating or dispersing pigments within their skin cells, the researchers found. Instead, the lizards rely on structural changes that affect how light reflects off their skin, the researchers said. Although chameleons are believed to have originated in Africa or Madagascar, the oldest known fossil, 26 million years old, is Chamaeleo caroliquarti from western Bohemia.

A. The waves would be exactly the same at points A and B.

Explanation:

The seismic waves at both point A and B would be exactly the same at the two points.

Seismic waves are elastic waves that spreads out concentrically in all directions from their source.

Both S and P waves are body waves that moves within the earth.
In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.

Which of these is ATP?

Pepsi [2]

Answer:

The correct answer is <em>A molecule consisting of three phosphate groups, ribose, and adenine.</em>

Explanation:

ATP means adenosine triphosphate, and it is a molecule which has a very important role in energy transfer in the cells. As its name says, it is composed by:

- adenine: a purine base, which is also a component of nucleic acids.

- ribose: a 5-carbon sugar (in contrast to deoxyribose, ribose has a -OH group in place of a -H group in carbon 2)

- three phosphate groups

Notice that adenine bonded to the ribose is called adenosine.
