next question:::

Why do terrestrial (land) animals use internal fertilization but aquatic (water) animals use external fertilization?

 

Here's what I know, Manjot.  Land animals can't use external fertilization b/c the egg and sperm can't survive out in the open air.  They need the internal environment to survive.  However, for aquatic organisms, it's much easier for the egg and sperm to meet in the water rather than internally.  Hope this helps...let me know if you have other Bio questions 😊

I think i should tell misha about this ANJALI TUTION CENTRE. She will be appearing for her 10th boards this year. 😆

😆 Ritu!!  Well as long as it's Biology (and maybe some chem and physics)-related, I can definitely help out! 😊

What are the 3 characteristics that make a metallic element different from a non-metallic element?

 

Adult sea anemones live in one location and do not move from it. Outline ways in which sexual reproduction would help them overcome a toxic waste spill.
