The amoeba is a eukaryote whose bodies most often consist of a single cell.
The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. For example:-
1. Their cytoplasm and cellular contents are enclosed within a cell membrane.
2. Their DNA is packaged into a central cellular compartment called the nucleus.
3. They contain specialized structures called organelles, which execute a range of cellular functions including energy production and protein transport.

Explanation:
caves and sinkholes are associated with karst topography because they are some of the main features.
<h2>Answer is option "1 B & 2 C"</h2>
Explanation:
- Evolution genetics is a field of science, which includes the study of genetic variations that lead to evolutionary changes in organisms
- As some bacteria had changed their DNA that led to the development of antibiotic resistance in them
- Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
- Hence, the right answer is option 1 B and 2 C " evolution Genetics & less bacteria becoming resistant to the specific antibiotics"
They both produce energy but the process is different. Aerobic respiration is when the cell produces energy using oxygen while anaerobic uses electron acceptors. Aerobic respiration also makes more energy.
