When we look at stars, we notice that some appear brighter than others. Sirius looks much brighter than Rigel, but is it really brighter? Or is Sirius much closer to Earth, giving it the appearance of being brighter? Actually, Sirius is about one hundred times closer to Earth than Rigel. If the two stars were the same distance from Earth, Rigel would appear much brighter. -We use two terms to reference the brightness of a star: absolute magnitude and apparent magnitude. Absolute magnitude is the measure of the light given off by a star, while apparent magnitude refers to the amount of light received on Earth. The color of a star indicates its temperature. Blue-white stars are very hot, while orange-red stars are relatively cool. In the early 1900's Ejnar Hertzsprung and Henry Russell noticed that the higher the temperature of a star, the greater the star’s absolute magnitude. They developed a graph that depicts this relationship called the H-R diagram. Most known stars fit into a diagonal band that runs from the upper left to the lower right of the diagram. This diagonal band is called the main sequence. About 90% of all stars are main sequence stars. Most stars are currently classified using the letters O, B, A, F, G, K, and M, where O stars are the hottest and the letter sequence indicates successively cooler stars down to the coolest M class. Betelgeuse is in the red spectral class. It is one of the largest of stars with extremely high luminosity although it has a relatively low surface temperature. How would Betelgeuse be classified?

Actually, Sirius is about one hundred times closer to Earth than Rigel. If the two stars were the same distance from Earth, Rigel would appear much brighter.

We use two terms to reference the brightness of a star: absolute magnitude and apparent magnitude. Absolute magnitude is the measure of the light given off by a star, while apparent magnitude refers to the amount of light received on Earth.

The color of a star indicates its temperature. Blue-white stars are very hot, while orange-red stars relatively cool. In the year of 1900's Ejnar hertzsprung and Henry Russell noticed that that the higher temperature of a star, the greater's the star absolute magnitude. They developed a graph that that depicts this relationship called H-R diagram.

Most knows stars fit into a diagonal band that runs form the upper left to the lower right of the diagram. This diagonal band is called the main sequence. About 90% of all stars are makn sequence stars.

Betelgeuse is the red spectral class. It is one of the largest of stars with extremely high luminosity although it has a relatively low surface temperature. Betelgeuse can be classified as supergiant. Thus option b is correct.

2. Adaptation is an organism changing to better themselves in a certain environment.

3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.

4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.

6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.

____ Helicase “unzips” the DNA-RNA hybrid
____ RNA polymerase joins the new RNA nucleotides into a single strand

____ Free RNA nucleotides make complementary pairs between their own

strand.

Answers

Answer:

6, 5, 4, 2, 1, 3

Explanation:

Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.

Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.

The process of transcription takes place in the following sequence:

1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.

2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.

3. The RNA  nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.

4. DNA helicase unzips the DNA and RNA hybrid.

5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.

6. The two-strand of DNA is again joined via complementary base-pairing rule.

How are the blunt and sharp pipettes

used in the cloning process?

(please answer in simple words i don't even understand the question)

Answers

Answer:

During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

Answers

Answer:

Human activities increases the concentration of oxygen in the atmosphere.

Explanation:

Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?

Answers

Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.

The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct

Explanation:

Answer:

The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.
