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.

Which of these is also known as the sublittoral zone?
Nataliya [291]

Answer:

b. the neritic zone

Explanation:

Neritic zone, also known as sublittoral zone, is a transition zone between the continental domain and the marine domain. It is the area that is under the influence of the tides and where light can penetrate to the bottom, promoting photosynthesis.

This zone is a complex, dynamic, changeable range and subject to various geological processes. The mechanical action of waves, currents and tides are important modeling factors of coastal zones, the results of which are erosion or deposition.
