What are the life cycles of flatworms and roundworms?

Biology
1 answer:
WINSTONCH [101]3 years ago
6 0
Flatworms-In the life cycle of trematode flukes of the subclass Digenea, mollusks (mostly snails) serve as the intermediate host. Fertilized eggs usually hatch in water. The first larval stage, the miracidium, generally is free-swimming and penetrates a freshwater or marine snail, unless it has already been ingested by one.
Roundworms-Roundworms can complete their life cycle in immature dogs, but as the pup's immune system matures (usually by 6 months of age), the larval stages of the roundworm will become arrested and will encyst (become enclosed in a cyst) in the pup's muscles. They can remain encysted in the dog's tissues for months or years.

Is fructose-1,6-bisphosphatase activated, inhibited, or unaffected in response to a glucagon signal?
Crazy boy [7]

Fructose-1, 6-bisphosphatase is activated in response to a glucagon signal.

<h3>What is the purpose of Glucagon signals?</h3>
  • Glucagon signals specify that fuel molecules are required in the bloodstream.
  • So these signals activate Fructose-1, 6-bisphosphatase (F1, 6BP) so as to increase the level of sugar and other fuels required for production of energy.
  • In the process of gluconeogenesis, new glucose molecules are synthesized from other non carbohydrate sources.
  • As glucose is required in the bloodstream so F-1, 6BP should be activated as it acts as a rate limiting enzyme in gluconeogenesis.
  • Gluconeogenesis occurs when the dietary intake of glucose is very low.
  • Glucose is required as a source of energy by almost all body cells so in case of less oxygen it is synthesized from other molecules like amino acids.
