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)
Answer and explanation;
-Strong acids and bases are defined as compounds that completely ionize in water or aqueous solution. Weak acids and bases only partially dissociate.
A strong acid will fully dissociate in water to form H+ ions.
HCl + H2O---> H3O+ + Cl-
This reaction is non-reversible. After dissolution, only a very very minute concentration of HCl itself remains in the solution, as most of the diluted HCl has dissolved into ions.
Ka = [H+] [Cl-] / [HCl]
The same applied for bases. The only difference is that the base dissociates to form OH- ions instead.
Strong and weak bases will depend likewise on whether the reaction is reversible.
A strong base will completely dissociate to give more OH- ions.
An example of a strong base;
NaOH + H2O ---> Na+ + OH- + H2O
Kb = [Na+] [OH-] / [NaOH]
Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes
Answer:
"Reproduction" is a characteristic of life that enables the continuation of a species

There are over 400 breeds of dogs in the world and all are maintained as pure-bred stocks through selective breeding,which aims to maintain a closed genetic lineage. Most dog traits follow simple genetic rules.
