8. Describe: Locate the Sun on the H-R diagram. How will the Sun's luminosity and
temperature change as it ages? How will these changes affect its position on the diagram?

Answers

Answer 1

Answer:

It will eventually become less bright and cooler.

Explanation:

Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.

The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.

Answer 2

Answer:

it will turn into a super giant then eventually turn into a white  dwarf star

Which region of the human alimentary tract has both the largest population of bacteria and the greatest species diversity

Answers

The region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

The normal flora of the alimentary tract

Normal flora are those microorganisms that resides in a living organism without causing it harm or diseases.

These normal flora become established in different parts of the body from birth such that the normal flora found in the mouth is not the same as the one found in the colon of the alimentary tract.

From research works, the large intestine (colon) is known to contain 100 billion per milliliter of fluid culture.

The massive numbers of bacteria in the large intestine (colon) creates a great special variation in the flora. The streptococci and lactobacilli found in the colon often adhere to cells by means of capsules surrounding the bacteria.

Therefore, the region of the human alimentary tract that has both the largest population of bacteria and the greatest species diversity is the the colon.

What does fossil evidence show about evolution?

Answers

Answer:

Answer below

Explanation:

Fossils provide physical examples of what organisms have looked like over time. For example, we can look at giraffes over time, who have evolved to have had long necks. When we look as fossil records of giraffes and similar species, we see that the longer ago that animal lived, the shorter their neck was, and as time progresses, the neck gets longer. However, we also see that in general the giraffes with longer necks, regardless of time period, will have lived longer and healthier lives (we can usually tell this just by how big the fossil is), as with longer necks the animal was able to reach more food and live longer. That giraffe then reproduced and shared their longer neck traits, while those with genetic markings to make their necks shorter will have died before reproducing. Therefore, we can see all forms of evolution through fossils.

7. What is the general relationship between the color of a filter/solution and the light that it absorbs?.

Answers

Answer:

A filter will absorb its complementary color of light. So a yellow filter absorbs blue light since blue is across from it on the color wheel. Whatever light is not absorbed will be transmitted; so yellow filters transmit red and green light (if incident upon it), also known as yellow light.

hope its helpful

A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.

What is filter?

A filter is a translucent substance that lets some colors flow through while absorbing others.

Color can only be produced by light. Color pigments (paints, dyes, or inks) display color by reflecting the light that isn't absorbed while absorbing some portions of the light spectrum.

The same principles govern how color filters function, with some color wavelengths being absorbed and others being transmitted.

Only yellow will pass through a yellow color filter while all other colors are absorbed. Therefore, if blue light is shone on a blue object through a blue filter, the object will still reflect blue and thus appear blue.

Therefore, A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.
