Answer:
The codons that code for LEUCINE amino acid are:
1. UUA
2. UUG
3. CUU
4. CUC
5. CUA
6. CUG
Explanation:
A CODON is a group of three nucleotides in the mRNA molecule that specifies a particular amino acid. It represents a trio combination of nucleotides (A, G, C, U). There are about 64 possible codons formed from four nucleotides used in a combination of three's i.e 4³ = 64. All the codons collectively form the GENETIC CODE, which is used by all known living organisms.
However, since there are only 20 amino acids in nature and 64 possible codons, more than one codon encodes an amino acid. This means that the genetic code is DEGENERATE or REDUNDANT. Hence, in this case involving the amino acid: LEUCINE, the six (6) codons that specify it (depicted in the attached genetic code) are as follows:
- UUA
- UUG
- CUU
- CUC
- CUA
- CUG

seedless vascular because it grows near water
Option D.
<u>Explanation:</u>
Vascular plants which are seedless are the plants which have vascular tissues in themselves. These tissues are a special kind of tissues which are responsible for transferring water and the other nutrients through out the plant.
Some of the examples of the plants which are vascular plants but are seedless are club mosses, ferns, whisk ferns and horetails is another example of such plants.
Abiotic<span> variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight.
