Answer: 1) Recessive allele is unable to express its effect in the presence of dominant allele WHILE a dominant allele is able to express itself even in the presence of its recessive allele.
2) Recessive allele produces its phenotypic effect only in the presence of a similar allele. E.g; tt is dwarf. WHILE a dominant allele does not require another similar allele to produce its effect on the phenotype. E.g; Tt is tall.
3) Recessive allele forms a defective polypeptide or enzyme so that the expression consists of absence of the effect of dominant allele. E.g; white flower colour in Pea. WHILE a dominant allele can form a complete polypeptide or enzyme for expressing its effects. E.g; red colour of flower in Pea.
Explanation:
Answer:
A.
Explanation:
Passive transport is defined as the movement of ion and other molecules through cell membrane without any energy input while active transport is the movement of ions and other molecular substances across cell membranes with an energy input which allows, molecules to move from a region of lower concentration to a region of higher concentration.
Uptake of iodide ions by thyroid cell is an active transport which is mediated by sodium/iodide symporter (NIS) protein, found in basolateral membrane of thyroid follicular cells. As the concentration of iodide ions is higher in thyroid cells, active transport make movement of iodide ions form extracellular fluid (lower concentration) to thyroids cells (higher concentration).
Hence, the correct option is A.
Answer: C)a branching chart that depicts evolutionary relationship among organisms
Explanation: Answer: A phylogenetic tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics

A life orientation refers to a subject studied in Grade 7-9 of South-African Schools. The purpose is to give students in school orientation on how they ought to behave in life and society.
<h3>What are the topics in Life Orientation?</h3>
Some of the topics you'd typically find in Life Orientation are:
- Goal setting
- Health, social and environmental responsibility
- constitutional rights and duties etc.
