Answer:
The correct option is;
Glaciers that once covered South Africa have melted and can no longer form.
Explanation:
The Karoo Supergroup that formed hundres of millions of year ago covered the most part of South Africa. 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.
Answer:
Explanation:
Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

Answer:
Chloroplast and mitochondria
Explanation:
Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.
Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.
