In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants parthenogenesis is a component process of apomixis.Apogamy is a type of reproduction, occurring in some ferns, in which the sporophytedevelops from the gametophyte without fusion of gametes.Adventitious embryony also called sporophytic budding, is a type of apomixis in which an embryo develops directly from nucellus or integument tissue.So, all three are correct.

• If you have type 1 diabetes your body does not release insulin.

Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions. The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.

In Type 1 diabetes, body do not produce any insulin. In type 2 diabetes, body can produce some insulin.

Hence, the given statement that most type 2 diabetics do not produce insulin is "FALSE."
