which statement has exceptions? (1 point)
sexual reproduction promotes genetic variation, while asexual reproduction does not.
sexual reproduction requires two parents, whereas asexual reproduction requires only one parent.
sexual reproduction is more complex, while asexual reproduction is a simpler process.
sexual reproduction involves parental care, while asexual reproduction does not.

Explanation:

• For the first option: Sexual reproduction (via meiosis, fertilization) creates genetic variation, asexual (like binary fission) usually has little variation (though mutations can occur, but the statement's general idea holds with few exceptions).
• Second option: Sexual reproduction needs two parents (gametes from two), asexual needs one (parent replicates), this is generally true with no major exceptions.
• Third option: Sexual reproduction has processes like meiosis, mating, etc., asexual is simpler (e.g., budding, fragmentation), this is generally true.
• Fourth option: There are exceptions. Some asexual reproducers (e.g., certain reptiles, insects, or even some fish in asexual modes) or species with asexual reproduction can have parental care, and some sexual reproducers may have minimal or no parental care (e.g., some fish, insects). So the statement "Sexual reproduction involves parental care, while asexual reproduction does not" has exceptions.

Answer:

D. Sexual reproduction involves parental care, while asexual reproduction does not.
