Archaea and Eubacteria are both forms of bacteria. Look at the short definitions of both of them. How are they different?

Answers

Despite being in the same category of prokaryotes, archaea and bacteria show variances in their genetic makeup, as the metabolic pathways, and other enzymes, genes possessed by the archaea closely resembles eukaryotes rather bacteria. Simple, microscopic, ambiguous microorganisms mark their presence universally, whether its deep in water, high temperature, soil or any extreme conditions. The evolving history of these cells is considered to be old as more than 3.5 billion years ago. Archaea and bacteria are the representatives of the prokaryotes and belong to the kingdom Monera. Archaea are considered to be the most primitive or ancient forms of life and denote the close relations to the first cells, which is deemed to arise about many years ago on earth. They were earlier classified as bacteria only and obtained name as “archaebacteria”, but due to the presence of certain unique features, they are now termed as ‘archaea’. They are inhabitants of very extreme environments.
Although like bacteria, which occupies the more significant part of the kingdom and are commonly found in the environment, archaea are also single-celled, lacking multicellularity, ranging in few micrometres. These essential differences and similarities are discussed in this content, with a brief description of them.
They probably have different niches and archaea was the first bacteria to exist. Archaea thrives in extrem conditions and is single called. Eubacteria thrives in normal conditions

Use the concept of natural selection to explain how a population of moths might evolve if only a few members can blend in with their environment.

Answers

Answer:

A great example is the peppered moths evolution. Since the Industrial Revolution the birch trees started to turn black from the soot. This casued all the white moths to be eaten from birds. The ones that were left to mate were black moths which favored the black gene. So overtime black moths became more common. They were naturaly selected based on color to survived and pass down their black colored genes.  

Explanation:

A population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

 

What is natural selection?

Natural selection is the force that selects the organism in the ecosystem that can fit best in the environment. In the case of the peppered moth, the light-colored moth was earlier camouflaged with the light color of the bark, so the dark moths were chosen by the predator. Later, after industrialization, the bark became black from pollution, allowing light moths to be seen and eaten by the predator, demonstrating how natural selection varies depending on environmental conditions.

Hence, the population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

Pictures taken by the Cassini spacecraft show that the rings surrounding Saturn have dark and light bands. Until these pictures were taken, scientists on Earth did not know about this difference in color. Why was the Cassini spacecraft able to take pictures of the dark and light bands in Saturn’s rings while they are not visible from Earth?

Answers

Answer:

Infrared images also show thermal, or heat, radiation. While a visible-light image from this vantage point would simply show the face of the planet as dimly lit by sunlight reflected off the rings, Saturn glows brightly in this view because of heat from Saturn's interior.

In a second version of the image, scientists "stretched" or exaggerated the contrast of the data, which brings out subtleties not initially visible.

When these small particles are lit from behind, they show up like fog in the headlights of an oncoming vehicle.

• The C ring also appears relatively bright here; not because it is made of dust, but because the material in it -- mostly dirty water ice -- is translucent. In fact, in the 18th and 19th centuries, it was known as the "crepe ring" because of its supposed similarity to crepe paper.

• The wide, middle ring known as the B ring -- one of the easiest to see from Earth through telescopes because it is densely packed with chunks of bright water ice -- looks dark in these images because it is so thick that it blocks almost all of the sunlight shining behind it.
