Prokaryotes, mitochondria and chloroplasts have many features in common.(a) (i) The diagram below shows a mitochondrion. Two of the features labelled are typical of prokaryotes. Place a tick in each of the two boxes that correctly identify these features.(FIGURE CANT COPY)(ii) The table below shows some features of mitochondria. If the feature is also present in chloroplasts, place a tick in the box to the right of that feature and if it is absent, place a cross in the box.(b) Bacteria can be identified and classified by looking for certain features. Using the information in the passage below, label the five bacteria with the correct letter. Bacterium has a single flagellum to enable it to move whilst bacterium has several flagella.Only bacterium has visible plasmids and bacterium has an infolding of its cell surface membrane.Bacterium T has a slime capsule.(FIGURE CANT COPY)

Texts: Question 2|Vraag 2 [17] Consider the tetrapeptide below. Beskou die tetrapeptied hieronder. NH 2.1. Indicate by writing + or - on those places in the structure where the positive and negative charges will be when this peptide is dissolved in buffer at pH 7. Toon aan deur die skryf van n(+ of -) op daardie plekke in die struktuur waar 'n positiewe en negatiewe lading sal voorkom wanneer die peptied opgelos word in buffer by pH 7. (2) 2.2. Encircle the asymmetric carbon in the first amino acid of the tetrapeptide that defines it as an L-enantiomer. Omkring die asimmetriese koolstof in die eerste aminosuur van die tetrapeptied wat dit sal eien as 'n L-enantiomeer. (1) 2.3. Indicate accurately with arrows where all the peptide bonds are in the tetrapeptide structure. Dui akkuraat met pyltjies aan waar al die peptiedbindings voorkom in die tetrapeptiedstruktuur. (2) 2.4. Classify the second and the third amino acids in the tetrapeptide as either polar-uncharged, polar-charged, or non-polar. Klassifiseer die tweede en derde aminosure in die tetrapeptied as polêr-ongeïoniseerd, polêr-geïoniseerd, of nie-polêr: Second amino acid: (1) Third amino acid: (1) 2.5. The molecular mass of the tetrapeptide is smaller than the combined molecular masses of the four amino acids from which the tetrapeptide was assembled. Explain why this is so. Die molekulêre massa van die tetrapeptied is kleiner as die gekombineerde molekulêre massas van die vier aminosure waaruit die peptied saamgestel is. Verduidelik waarom dit so is. (2)
