How does the migration of humpback whales increase their odds of reproduction?

Coral can reproduce sexually by releasing gametes (reproductive cells) into water during mass spawning events.  They can also reproduce asexually by through budding, where a single coral polyp is divided into two or more genetically identical offspring.

Here a coral with polyps exposed releases sperm into the water

Explain why it’s an advantage for coral to be able to reproduce sexually and asexually.

What do robin parents do to increase the odds that its offspring survive?

Kangaroos give birth to relatively undeveloped young. At birth, a kangaroo joey is only about the size of a jellybean, and its eyes, ears, and limbs are not fully developed.

Kangaroo and Joey

Why do you think a kangaroo mother carries her young joey in her pouch?

How does this increase the odds that the young joey will grow up strong and healthy?
