There are two questions (1 and 2), answer are provided as such. The cha
Answer to Question 1
Population --> Whole Organism --> Organ system --> Organ --> Tissue --> Cell
Explanation:
- The cell is the simplest, basic and functional unit of life.
- Tissue is a collection of similar cells e.g brain tissue
- Organ is a collection of similar tissues e.g Liver, Lungs
- Organ system refers to a group of closely related organs performing the same function in an organism.
- Organism comprises of well-coordinated organ systems.
- Population refers to the total number of organisms living and breeding together.
Answer to Question 2
Cell --> Genome --> Gene --> Nucleotide
Explanation:
A cell consists of a nucleus and other organelles. Within the nucleus & other organelles like mitochondria lies the total genetic material of the cell known as GENOME.
- The genome contains several functional sequence of bases known as GENE.
- A gene is made of triplets of nucleotides (codons)
If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.
Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.
The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.
In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).

<h3><u>Answer;</u></h3>
A). Organic compounds would not be available for use by autotrophs.
<h3><u>Explanation;</u></h3>
- The stability of an ecosystem depends on the actions of the decomposers.
- Therefore, if there were no decomposers in an ecosystem then, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
- The carbon and nitrogen necessary to build organic compounds, and then cells, allowing an organism to grow, would be insufficient. Other nutrients necessary for an organism to function properly would also not be sufficient.
