<h3><u>Answer</u>;</h3>
C. Phospholipids form a selectively permeable structure
<h3><u>Explanation</u>;</h3>
- Phopholipids are types of lipids which are amphipathic molecules, that is they have both non-polar and polar end.
- They are fundamental building blocks of cellular membranes and are the major part of surfactant.
- <em><u>Phospholipids are selectively permeable that is they allow some molecules but not others to pass across it. The phospholipid bilayer is permeable to small polar molecules and nonpolar molecules. They bilayer is impermeable to larger polar molecules and ions</u></em>.
<u>Answer</u>: Bacteria through the nucleoid (number 5).
<u>Explanation</u>:
Both paramecium and bacteria are single celled organisms. However, they differ by the fact that the first one is an eukaryote and the second one a prokaryote.
Furthermore, they differ in their capacity to mutate and adapt to environmental changes. Bacteria have a simple internal structure that lacks any organelles and are very adept at adapting to environmental changes. Besides their capacity for high mutation rates, they are also capable of picking up genetic information from their environment through a process called <em>transformation</em>.
Through transofrmation, environmental DNA enter the living bacteria through its cell membrane. Double stranded DNA will have one strand dissolved through hydrolysis, whereas the second strand may recombine with the bacterial <em>chromosome (nucleoid)</em>. Thus, this new genetic material will become incorporated into the bacterium's genome.
Gold, Silver, and Copper are all part of a class of minerals called: native elements. Platinum, Graphite, Diamond and Mercury are also apart of this group. It is also known as the native metals.
