Pine trees are pollinated when the wind carries pollen grains from male pinecones to female pinecones. The female pinecones contain egg cells. Which statement describes what happens in a female pinecone during fertilization?

Here are the answers to your questions:

Question 4:
Fertilization involves the fusion of haploid male and female gametes to form a diploid zygote. In pine trees, pollen grains contain the male gametes (sperm cells), and the female pinecones contain egg cells. Both sperm and egg cells are haploid.
The correct option is B) A haploid sperm cell and a haploid egg cell fuse together to form a zygote.

Question 5:
When a tadpole loses its tail during metamorphosis, this process involves programmed cell death (apoptosis) and the breakdown of the tail tissue. Lysosomes are organelles that contain hydrolytic enzymes. Their function is to break down cellular waste, debris, and in this case, the cells of the tail.
The correct option is C) Lysosomes release enzymes that help break down tail cells.
