1.1.1 Which ONE of the following is INCORRECT about functions of mitosis? A Repairs damaged tissues B Replaces dead cells C Halves number of chromosomes D Promotes growth 1.1.2 The organelles that synthesise proteins are called... A ribosomes. B mitochondria. C chloroplasts. D nucleoli. When viewing a specimen, the total magnification is 400 x . If the magnification on the eyepiece is 10 x then the magnification on the objective lens is ... A 4 xx . B 40 x . C 200 x . D 400 x . (6)

Mitosis is a remarkable process, allowing cells to replicate and repair themselves! It's essential for growth, replacement of dead cells, and healing. However, it intriguingly keeps the chromosome number stable, so if one were to halve the chromosomes, that's a job for meiosis, the fanciful dance of gamete formation. So, it’s C that doesn’t fit! Ribosomes are the unsung heroes of the cell, tirelessly churning out proteins like a master chef whipping up delightful dishes! These tiny structures can be found floating around in the cytoplasm or attached to the endoplasmic reticulum, diligently crafting the proteins that power cellular functions. So, the correct answer here is A! For total magnification fun, remember: Total Magnification = Eyepiece Magnification x Objective Magnification! So, if your total magnification is 400x and your eyepiece is 10x, you simply divide: 400 / 10 = 40x for the objective lens. That makes B or 40x, a winning choice!
