Answer: The correct option is A
Archae bacteria are extremophiles which thrive in extremely environment.
Explanation:
Extremophiles are organisms that inhabit extreme environments. They thrive in hot niches, ice, and salt solutions. Some of them grow in toxic waste, organic solvents and heavy metals. Extremophiles include members of all domains of life which are bacteria, archea,and eukaryotes. Out of these three members of extremophiles, archea are the main group of microorganisms to thrive in extreme environments. This is because the archea are skilled in adapting to different extreme conditions than bacteria and eukaryotes.
Archea are hyper thermophilic microorganisms.
Our perception of the brightness of a color is affected mainly by: the amplitude of light waves.
Night and peripheral vision depend mainly on rods, while daylight and acute vision depend mainly on cones.
The amount of light entering the eye is regulated by changes in the size of the pupil.
If you project a red, a green, and a blue light into space, the point at which the three lights cross will lead to the perception of white light.
eric has been wearing red welding goggles for the past 30 minutes. Based on the opponent-process theory of color vision, when Eric takes off the red goggles, he should expect that objects will temporarily appear to be green.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the keys words in the question provides an idea of what the completed question is.
There are two types of nucleic acid; ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).
They are both made up of ribose/pentose sugar, nitrogenous base and phosphate group.
The ribose sugar of the DNA is one oxygen less than the ribose sugar of the RNA hence the reason for the name "deoxyribose".
There are five nitrogenous bases namely; adenine, thymine, guanine, cytosine and uracil. They both contain adenine, guanine and cytosine; however, the DNA contains thymine while the RNA contains uracil. Of the five bases, adenine and guanine are the purines (have a double ring structure) while the rest are pyrimidines (have a single ring structure).
The phosphate group here is negatively charged
Answer:
The DNA double helix unzips.
A strand of RNA is made from a strand of DNA.
The strand of RNA leaves the nucleus.
The strand of RNA moves to the ribosome.
A protein is produced.
Explanation:
During protein production, the messages in DNA are first encoded into mRNA in a process known as transcription. Transcription happens in the nucleus and involves an initial step of unwinding or unzipping of the double helix DNA.
Thereafter, the mRNA produced during transcription is transported from the nucleus to the cytoplasm where it gets attached to the ribosome.
In conjunction with the rRNA and the tRNA, the codons in the mRNA becomes translated into their respective amino acids. The amino acids are then linked by a polypeptide bond leading to the production of protein.
Hence, the correct sequence of event is:
<em>The DNA double helix unzips.</em>
<em>A strand of RNA is made from a strand of DNA.</em>
<em>The strand of RNA leaves the nucleus.</em>
<em>The strand of RNA moves to the ribosome.</em>
<em>A protein is produced.</em>
