Is a full eye transplant possible?

ser-zykov [4K]

Answer:

<h2>There is currently no way to transplant an entire eye. Ophthalmologists can, however, transplant a cornea. When someone says they are getting an “eye transplant,” they are most likely receiving a donor cornea, which is the clear front part of the eye that helps focus light so that you can see.</h2>

Which best describes the offspring of protists?

Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.
