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.

Answer:
Clam.
Explanation:
Arthrophoda is largest phylum of the non-chordata. They are the segmented animals with jointed appendages. Their body is covered by exoskeleton and contains spiracles and body surface for respiration.
Insect, spider, crab and scorpion all are included in the phylum arthropoda. Clam is a bivalve shell that is included in the phylum mollusc. The body of clam is covered with an outer shell and their shells are connected by the abductor muscle. Hence, they are involved in phylum arthropoda.
Thus, the correct answer is option (b).
