Answer:
C. Phylum.
Explanation:
Out of the 8 taxonomic ranks, the phylum is the 3rd most diverse rank. In the 4 choices given it the highest rank.
Organization Levels:
Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Not sure if it is correct since there are different answers but it is what I think is correct.
Answer:
ACA: Threonine
CAC: Histidine
Explanation:
To answer this question we need to remember that the ribosome reads every three bases or 'codon' in order to assign the right tRNA carrying the amino acid.
In the first artificial mRNA we see two patterns of three letter:
CAC and ACA.
In the second artificial mRNA we are able to identify three different patterns:
CAA
AAC
ACA
And they repeat, so we end with three different polypeptides: polythreonine, polyglutamine and polyasparagine. This will depend on the initial letter the ribosome starts reading.
The only amino acid that repeats in both artificial mRNAs is Threonine, and we see its pattern ACA also repeated.
So, we could assign this codon (ACA) to threonine.
We can then assume that the pattern CAC codifies for histidine since we only get this two polypeptides in the first mRNA.
Lastly with the information provided we cannot determine the codons AAC and CAA for glutamine or asparagine. We would need further experiments.
Forgetting
is the apparent loss or modification of information already encoded and
stored in an individual's long term memory. It is a spontaneous or
gradual process in which old memories are unable to be recalled from
memory storage. Forgetting also helps to reconcile the storage of new
information with old knowledge.
Hope this helps :p
the tumor is made of cancer cells, and it can invade nearby tissues. Some cancer cells can move into the bloodstream or lymph nodes, where they can spread to other tissues within the body.
The answer would be “a. True” hope I helped in time!
