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

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

Which of the following statements does NOT describe a vertebrate eye?
Scrat [10]

The correct answer is: d. it contains many light-sensing columns called ommatidia

Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.

The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.

A species that is not native to a particular region
siniylev [52]

Answer:

A species that is not native to a particular region is called an <u>invasive species. </u>

Explanation:

In ecology, invasive species can be described as species which are introduced into an environment. These species are not native to the environment.

Introduction of invasive species in an environment can destroy a stable ecosystem. The invasive species will compete for resources like food, shelter, water etc. They might cause the extinction of the species on which they start feeding.  They might fight with predators feeding on the same prey.
