Your answer is C: 2 billions years! Hope that helps!
Osmosis<span> (diffusion of water across a membrane) causes </span>plant<span> cells to gain or lose water, which increases and decreases </span>turgor pressure<span>, respectively. </span>Plant<span> cells gain water when the concentration of water is higher outside the cell. This is called hypotonic conditions (hypo=low solute outside)</span>
In general, a point mutation alters a single base in the DNA (gene) which can potentially alter the identity of a SINGLE amino acid in the protein sequence.
<span>Also, it might be a good idea to ask biology questions in the Science and Math section. More of us answer there more often than here.</span>
<span>The answer
is ii). Invasive species spread rapidly
in the new habitat/environment in which they
are introduced. They spread rapidly due
to lack of natural predators in the new environment
hence reproduce unchecked. They upset the balance of an ecosystem and cause environmental
damage. </span>
Protists are a group of organisms that are characterized as Eukaryotes that are neither plants nor animals nor fungi. They are very diverse, and there are many hypotheses about their classification. The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis.
It is acceptable because data are still being collected.
It is acceptable everything in science should always change.
It is not acceptable because the correct answer needs to be found.
It is not acceptable because science never changes.
Answer:It is acceptable because data are still being collected.
