A. Both involve two parents and result in genetically identical offspring.
B. Sexual reproduction involves one parent, while asexual reproduction requires two.
C. Sexual reproduction results in greater genetic variation than asexual reproduction.
D. Asexual reproduction leads to more diverse offspring than sexual reproduction.
C. Sexual reproduction results in greater genetic variation than asexual reproduction.

3. A scientist observes a group of organisms that produce genetically identical offspring. Which type of reproduction are these organisms most likely using?
A. Binary reproduction
B. Asexual reproduction
C. Fertilization

Which structure is found in both cell types and is responsible for producing proteins?
Ribosome
This flexible barrier controls what enters and exits the cell.

A chameleon's ability to change color is an example of an adaptation for what purpose?
Camouflage (Protection/Predator Avoidance)
4. Why is sexual reproduction more likely to increase the genetic variation in a species?
A. It allows traits to be copied directly from one parent.
B. It produces fewer offspring, so mutations happen more often.
C. It involves combining genetic material from two different parents.
D. It only occurs in multicellular organisms.
C. It involves combining genetic material from two different parents.
True or False: Both plant and animal cells have a nucleus.
True
Which organelle is the site of protein synthesis?
Ribosomes
Is this an animal or plant cell? Explain.
C. A cactus having thick, waxy skin to reduce water loss.
5. Which answer is correct about reproduction?
A. All organisms that reproduce asexually have high genetic variation.
B. Sexual reproduction increases the chance of genetic differences.
C. Asexual reproduction always results in mutations.
D. Fertilization leads to genetically identical offspring.
B. Sexual reproduction increases the chance of genetic differences.
