Which is the main reason toads must lay eggs in water?

1 answer:

The answer is A. The eggs do not have a shell to prevent water loss.

Toad's eggs do not have a shell, like reptile eggs or bird eggs. Shell is important because it protects eggs from drying out if they are laid in the land. Toads lay eggs in a jelly-like glycoprotein. Thanks to glycoprotein around toad's eggs, contact with water is maintained all the time so that eggs don't die.

Answer:

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.
