Answer:
The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"
Explanation:
All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.
One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
there are two or three types or methods in which they change according to the class you study so this a answer from a 8th grader ( there are difference in classes)
<u>Nitriates</u> are a form of <u>nitrogen</u> that is usable by plants.
It is assimilated into plant tissue as protein. The nitrogen is passed through the food chain by animals that consume the plants, and then released into the soil by decomposer bacteria when they die.
Nitrification is the conversion of ammonia (NH3) to nitrate (NO3). It is usually performed by soil living bacteria, such as nitrobacter. This is important because plants can assimilate nitrate into their tissues, and they rely on bacteria to convert it from ammonia to a usable form.
denitrifying bacteria convert nitrogen into ammonia which is a form of nitrogen that is useful to humans. Bacteria "fixes" gaseous nitrogen into nitrogen usable by plants in the form of nitrate.
Answer:
The correct answer is option d.
Explanation:
An extinct species of australopithecine, that is, Australopithecus africanus was the first species to be illustrated. It was of gracile or slender build and was considered to have been the direct ancestor of modern humans. Like modern man, the A. africanus did stood upright and walked upright, and were having free hands to use. However, they were smaller in height and lighter in weight in comparison to modern man.
Adaptors are unconscious, and can be signs of many things as they are menial gestures we create in response to certain situations. It's a form of nonverbal communication that doesn't really fall into any one category besides the first. My best guess is A, by this understanding.
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid.
AAU codes for the amino acid called threonine.
GGC codes for the amino acid called glycine
UAC codes for the amino acid called tyrosine.
So the chain will read threonine-glycine-tyrosine.
There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.
