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 a virus because a virus is the only microbe that cannot reproduce on its own without a host. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.

In lytic cycle, 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.

In lysogenic cycle, 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.

How many combinations for a protein that’s 10 amino acids long

Paul [167]

The number of combinations for a protein that’s 10 amino acids long would be - 3628800

Permutations are the management of items in an orderly manner, this focuses on the order of the items. In the given case, the order of the amino acids matters to find out the number of combinations.

The formula is:

nPr = n! / (n-r)!;

where,

n = number of elements
r = number of elements required in each set.

Permutation formula applied in this case:

$^{n}P_{r}=\dfrac{n!}{(n-r)!}^{10}P_{10}=\dfrac{10!}{(10-10)!}^{10}P_{10}=\dfrac{10\times 9\times 8\times 7\times 6 \times 5\times 4\times 3\times 2\times 1}{0!}\\^{10}P_{10}=\dfrac{3628800}{1}\\^{10}P_{10}=3628800$

Thus, the number of combinations for a protein that’s 10 amino acids long would be - 3628800
