Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell
According to the research, the statement is true, animal viruses often have glycoprotein spikes on their capsids or envelopes.
<h3>What are viruses?</h3>
It is an obligate intracellular parasite, small in size, made up of nucleic acid and protein.
They have a layer or envelope of lipids and glycoproteins, which they obtain from the cell membrane of their host cells, and which is used to inject genetic material into the cell.
Therefore, we can conclude that according to the research, the statement is true, animal viruses often have glycoprotein spikes on their capsids or envelopes.

answer: when you choose a blue habitat there is disadvantage for the red beads and an advantage for the blue beads while when you choose a red habitat there is a disadvantage for the blue beads and an advantage for the red beads
Explanation:
There is a selective advantage for the red and blue beads and the selective advantages are :
when you choose a blue habitat there is disadvantage for the red beads and an advantage for the blue beads while when you choose a red habitat there is a disadvantage for the blue beads and an advantage for the red beads. what this simply means is that the change in the habitat cause a proportional change in the phenotype
