False, because they have different masses. The ball with then heavier mass will land first. The ball with the lighter mass will land second.
Answer:
a virus, because it requires a host cell to reproduce
Explanation:
- a bacterium, because it is contagious
-
a fungus, because it infects livestock
-
a protist, because it is microscopic
-
a virus, because it requires a host cell to reproduce
The correct answer would be <u>a virus because a virus is the only microbe that cannot reproduce on its own without a host</u>. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.
<u>In lytic cycle</u>, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.
<u>In lysogenic cycle</u>, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.
Change over time. I believe this is a multiple choice question, but you have not provided the options.
Answer:
Furthermore, what kingdoms have no cell walls? Protists that are similar to animals do not have cell walls at all. Plant- and fungi-like protists have cell walls that are similar to plants. Other protists have a unique cell wall that is different from cell walls seen in other eukaryotic kingdoms.
