The carbon cycle maintains the balance between the organic remains and carbon dioxide. In this cycle the the incorporation of carbon dioxide inside the plants by photosynthesis occurs and it is returned to the atmosphere by the process of respiration as well as the decaying dead organisms.
It breaks down lactose into the galactose and glucose. So the answer here is C.
Answer:
Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.
In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.
After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.
After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.
With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.
Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.
Explanation:
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
