>Some hormones such as steroid hormones act by binding to DNA and attering gene expression. Other hormones bind to membrane receptors, where they either open ion channels (usually Ca + + ) or trigger production of other chemical messengers inside the cell. Typically the receptor activates an e..

Nutrition in amoeba is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. It is an omnivore, feeding on both plants and animals. Its diet includes bacteria, microscopic plants like the diatoms, minute algae, microscopic anim..

Lysosomes are tiny, spherical sac-like structures evenly distributed in the cytoplasm. They are seen practically in all animal cells with the exceptions like mature mammalian RBC. Largely, they are absent in plant cells. The membrane that surrounds a lysosome, encloses a variety of lytic ..

It is found in aquatic animal groups like sponges, coelentrates, crustaceans, echinoderms, bony fish, tadpole larvae and salamander. Ammonia is produced as a result of catabolism of proteins, especially in the liver cells by oxidative deamination of excess of amino acids in the presence ..

. Secondary carnivores are preyed upon by some larger carnivores. Tertiary carnivores or Quaternary consumers include the animals, which feed on the secondary carnivores. For e.g., lion, tiger, etc. These are not eaten by any other animals. The larger carnivores, which cannot be..

The sperm generally comes in contact with the ovum at the animal pole. A number of sperms surround the ovum, but only one of them fuses with the egg. Fertilisation of the egg with only one sperm is known as monospermy. Fertilisation occurs in the ampulla of the oviduc..
