The correct answer is: 2.metaphase.
Mitosis is a process of cell division and it is separatd into phases.
• Interphase-DNA replication (two identical full sets of chromosomes),
• Prophase-chromosomes composed of two sister chromatids with identical genetic information,
• Metaphase- chromosomes line up along the centre of the cell,
• Anaphase- chromatids are pulled apart by the mitotic spindle (one chromatid to one pole and the other chromatid to the opposite pole),
• Telophase- a full set of chromosomes at each pole of the cell.
It is used to demonstrate the importance of chlorophyll in photosynthesis. Plant with variegated leaves is de starched and then placed in the sunlight for a few hours, then the iodine test for starch is carried out. The green parts of the leaves will test positive for starch and therefore turn blue black. The non-green parts did not photosynthesize die to absence of chlorophyll and iodine color will remain brown.
Valine is a hydrophobic amino acid used for biosynthesis of proteins. It is essential in humans, meaning the body cannot synthesize it and it must be obtained from the diet.
Glutamic is a hydrophilic amino acid used by almost all living beings in the biosynthesis of proteins. It is non-essential in humans and the body can synthesize it.
Abiotic factors (any non living components) that shape the desert include high wind speeds, arid conditions, low cloud cover, heavy sun, sand, and low rain fall.
