Which is a reflex response?

Answer/ explanation :

Reflex response is an involuntary, automatic and rapid response to a stimulus.

It's is controlled by the brain stem.

Reflex actions cannot be controlled. They are coordinated by nerves which moves to and fro in the spinal cord without a direct involvement of the brain.

Examples of a reflex response

Sneezing, coughing, yawning, toughing a hot object, blinking of the eyes.

There are two types of reflex response

Autonomic reflex arc

The somatic reflex arc

The reflex responses happens so quickly because they do not have to be processed by the brain before taking place.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
