Absorption spectroscopy is a technique used to determine the composition of a substance. Each substance tends to behave consiste

ntly in terms of which types of radiation it absorbs. When a material absorbs a unique set of different colors of visible light, the characteristic set of color bands observed through a spectroscope is the material's spectrum. The spectra of two stars are shown below.

Star 1 is a nearby star and star 2 is a similar type star much further away from Earth. When comparing the spectra, the lines in the spectra for star 2 are closer to the red end of the light spectrum. This is called red shift.

From this type of information, scientist believe that most stars in the universe are moving away from each other and from the Earth. How can redshift be used as evidence to support the Big Bang theory?
A.
It provides evidence that some stars remain motionless while others move rapidly, showing that the universe is expanding in very few areas.
B.
It provides evidence that some stars are pulled toward a point source, and some move away from a point source, showing the universe may be contracting.
C.
It provides evidence that stars are moving away from a single point of origin, showing that the universe is expanding.
D.
It provides evidence that stars are moving closer to a single point of origin, showing that the universe is contracting.

The ecumenical thought of utilizing the trophic level with conventional parasites (fleas, ticks, and tapeworms) Would be that parasites are consumers. A symbiotic-relationship, a procedure enacted to survive. Parasitism is the act of one parasite surviving off of another organism (host). Parasites may affect hosts differently than predators affect prey. While a predatory animal murder copious individuals during its life, a parasite prevails sustenance from an undivided host during a life stage. Similar to omnivores, some parasites can extend their dependencies with their nutrients and prefer multiple trophic levels, not just one.

(Psst, I hope I facilitated you with the explanation. I am moderately atrocious at explicating matters, dismal.)

Multiple choice---

The answer to number two, would be "D", as "transpiration" is the diametric occurrence to all the other processes. Rather bounteously returning carbon dioxide, it actually holds the carbon dioxide, happening in the stomata, opening itself up to "breathing in" the carbon dioxide, and release oxygen.

The result to number three, would be "D", as "change of seasons" would not be possible for such things like forests. The alteration would not occur in an antecedently damaged area, for change has been interrupted and requires time to fixate.

The solution to number four, would be "B", as plant-life occurrences is an augury of a primary succession and that an environment has begun commencement or is now fixated.

The restriction enzyme bamhi recognizes the dna sequence ggatcc and always cuts between the two g nucleotides. how many bases lo
vladimir1956 [14]

The correct answer is four base pairs.

BamHI is endonuclease meaning that it has the ability to cut DNA at specific target site. The recognition sequence of BamHI is 5'-GGATCC-3 and it cleaves it after the first G. Sticky ends are formed as a result of that cleavage remaining a four-base 5' overhang in one molecule and a complementary 5' overhang in the other. These ends are can be joined back together by an enzyme called ligase.

Many bacteria, including E. coli, are capable of growing under both anaerobic and aerobic conditions. Some mutations are introdu
Sloan [31]

Answer:

Due to inability to survive in aerobic condition.

Explanation:

The strain dies when exposed to a normal laboratory atmosphere instead of nitrogen gas atmosphere because the mutation causes change in the capability of the strain to survive in the aerobic conditions. This mutation inactivate several enzymes which is also responsible for their capabilities of surviving under both anaerobic and aerobic environment so that's why the strain dies when exposed to normal atmosphere..
