Reproduction：练习题

Asexual reproduction in a coral polyp results in offspring that are genetically identical to the parent. The resulting offspring are therefore best described as:

A marine biologist observes a single-celled protoctist undergoing a process where it produces two new cells that are genetically identical to the original parent cell. Which statement about this process is correct?

The life cycle of a coral polyp involves both asexual and sexual reproduction. Which statement correctly identifies a difference between these two phases?

Asexual reproduction, such as budding in a coral polyp, is characterized by the production of offspring that are:

In the life cycle of the leatherback turtle (Dermochelys coriacea), what is the primary factor that determines the sex of the offspring during the incubation of the eggs?

State the key difference in genetic material between offspring produced by asexual reproduction and those by sexual reproduction.

Many species of coral utilize a method of sexual reproduction involving the synchronized release of gametes. Explain one biological advantage of this synchronisation for the survival of the species.

State the main difference between asexual and sexual reproduction regarding the number of parent organisms involved.

The leatherback turtle (Dermochelys coriacea) has a distinct and well-documented life cycle.
(a) State the type of habitat female leatherback turtles return to when they are ready to lay their eggs.
(b) Describe how the temperature during the incubation period influences the development of the turtle embryos.

Reproduction in the marine environment involves various biological processes.
(a) Explain the genetic difference between offspring produced by asexual reproduction and those produced by sexual reproduction.
(b) In the context of the coral polyp life cycle, describe the process of sexual reproduction and explain the importance of the planktonic larval stage.
