First we establish a table of genotypes and phenotypes:

genotype  phenotype
AA             type A
BB             type B
AB             type AB

Homozygous type A   has genotype AA
Homozygous type B   has genotype BB

Now we make the punnett square

           A             A
B        AB          AB
B        AB          AB

So we see that all (100%) of outcomes are type AB.

The Tillite debris from melting glaciers, in Dwyka Tillite are located at the bottom layers of the Karoo Supergroup, which is an indication that millions of years ago, South Africa was under extensive glacier coverage formed during the movement of the continent past the South Pole

The eventual arrival of the continent to temperate regions away from the South Pole resulted in the melting of the glaciers from which a huge swamp was formed.

18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.

19.  The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.

20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.
