4a. By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants

Biology
1 answer:
Mila [183]3 years ago
5 0

Answer:

See the answer below

Explanation:

The amount of herbaceous plants in an abandoned farm field will keep decreasing with time and the amount of trees would be increasing instead <u>due to successional forces.</u>

Succession refers to the gradual change in the species structure of a community with time. Early successional species usually colonize new habitats and with time, they are replaced with late successional species until a relatively stable community, climax community, is established.

<em>Herbaceous species on abandoned farmland represent early successional species and as time goes on, they will be replaced by mid to late successional species in the form of shrubs and trees until a relatively stable community is formed. Hence, herbs would be decreasing while trees would be increasing. </em>

The Genetic Code was cracked by several different types of experiments. Some involved the synthesis of an RNA strand (that acted
Igoryamba

Answer:

A. Repeats of "Alanine-Arginine"

B. Repeats of "Tyrosine-Isoleucine"

C. Repeats of Aspartic acid

Explanation:

A. The synthetic RNA with GC repeats would have repeats to two codons: GCG and CGC which in turn code for alanine and arginine amino acids respectively.  Hence, its polypeptide would have repeats of "Alanine-Arginine"

RNA: GCG CGC GCG CGC GCG CGC  

Alanine-Arginine-Alanine-Arginine-Alanine-Arginine-Alanine-Arginine ...

B. The synthetic RNA with UA repeats would have repeats to two codons: UAU and AUA which in turn code for tyrosine and Isoleucine amino acids respectively.  Hence, its polypeptide would have repeats of "Tyrosine-Isoleucine"

RNA: UAU AUA UAU AUA UAU AUA

Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine

C. The synthetic RNA with GAC repeats would code for polypeptide of aspartic acid only as GAC codes for aspartic acid.

RNA: GAC GAC GAC GAC GAC GAC
