Answer:
This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence.
the size of a Codon is 3 nucleotides.
The 20 amino acids are encoded by combinations of four nucleotides
If a codon were two nucleotides, the set of all combinations could only encode 16 amino acids.
since Codons are made up of three nucleotides, the set of all combinations can encode 64 amino acids. {i.e. 64 different combinations of four nucleotides taken three at a time.} But of the total of 64 codons, 61 encode amino acids and 3 specify termination of translation.
I hope this Helps!
Answer:
I think the answer is a plant cell contains one large vacuole in its wrong because they have a nucleus I did not all plants have the same size or shape and they only have one large vacuole or sap vacoule hope it helps
Anthony has been refusing to go to school. Anthony's culture places great emphasis on academic achievement and expects that young people will get no grade lower than an A, and his teacher wonders whether that may be influencing Anthony's school refusal. This illustrates operation of the Macrosystem.
<h3><u>
Explanation:</u></h3>
Urie Bronfenbrenner has developed a theory of ecosystems in which the macrosystem deals with the culture in which an individual survive. There are five differemt environmental systems that has been dealt with this system in which the individual interacts. They are mesosystem,macrosystem, microsystem, chronosystem and exosystem.
When the culture is dealt as a whole and dealing with poverty,ethnicity,status in socioeconomic context and wealth is Macrosystem. They also deal with children their studies and the working nature of their parents. The example given here deals with an individual's emphasis towards academic and the things that influence him. Thus it illustrates the operation of Macrosystem.
