Answer:
b. They cannot reproduce outside of a host cell.
Explanation:
Viruses are <em>parasitic organisms</em> that need a<em> host</em> in order to<u> thrive</u> and <u>reproduce</u>. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means <em>being restricted to a specific mode or function in life</em>. This shows that the virus has a restriction when it comes to <u><em>reproduction.</em></u> It cannot reproduce without finding a host cell.
Yo that’s dark. Like dark.
Bacterial transformation , a process in which recipient cells acquire genes from free DNA molecules in the surrounding medium.
<h3>What is the transfer of DNA from a donor to a recipient cell calledcalled ?? </h3>
Conjugation is the process of by which on bacterium transfers genetic material to another through direct contact. During conjugation one bacteria serves as the donor genetic material and other serves as recipient .
So, the Bacterial transformation is a process in which recipient cells acquire genes from free DNA molecules in the surrounding medium .

Answer: Option A) The seals would decrease in number and the phytoplankton would increase in number
Explanation:
The food web can be illustrated as follows: Seal --> Krill --> Phytoplankton
Where phytoplankton is the producer of food, krill is the primary consumer while seal is the secondary consumer.
So, reducing the krill population would immediately cause food shortage for seals, and lessen consumption of phytoplanktons.
Thus, the seals would decrease in number due to starvation and death, while the phytoplankton would increase in number
Melanin helps protect the body from the sun's radiation. Since light skinned people have less melanin so, they have less protection. Less protection can lead easily to skin cancer making the person less fit to the environment.
To avoid that, they should use solar protector in areas that receive high amounts of UV light.
