66% of new HIV infections occur in sub-saharan Africa.
Answer:
D
Explanation:
Methanogens are prokaryotes and therefore have prokaryotic cells. They are single-celled archaea. They are found in hypoxic conditions like the first stomach of ruminants where they digest molecules like cellulose and produce methane as a byproduct. The rest are composed of eukaryotic cells which are much larger than prokaryotic cells and their organelles are membrane-bound (unlike prokaryotes).
Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.
<h3 /><h3>What is the Hypothesis?</h3>
Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.
