Cyanobacteria are oxygenic photosynthetic bacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation. ... Cyanobacteria are found in various land biomes and aquatic environments.
Answer:
1. In order to fix the bacterial to the slide;
<u>so that it will not be lost during the staining procedure.</u>
<u>so that false impression or result will not be given by the bacteria in water,</u>
<u>Distilled water is used to prevent contamination with impurities e,g metals ions and crystals</u>.
Explanation.
In smear preparation; the bacterial cells should also be well dispersed,so that they do not clumped together to form' big glob'.(large round masses) The later affect clear field view of the bacterial mophology, affected staining, and therefore gives inaccurate results,
Fixing to the slide also affects the morphology of bacterial cells, through shrinking in size, which can lead to loss of structural characteristics and extra-cellular matrixes,
Enzymes are in the Proteins class
1a & b:Homozygous Recessive = ff - white flowers
Homozygous Dominant = FF - Purple flowers
Heterozygous = Ff - Purple flowers
2:The punnet square will look something like this
Tt Tttt tt
50% Heterozygous (with long thorns)
50% Homozygous Recessive (with short thorns)
