Explanation:

The blue-ringed octopus, shown below, utilizes a venom called tetrodotoxin as a defense mechanism.Tetrodotoxin binds to sodium channels and blocks the passage of sodium ions. Based on this information, which symptom would most likely occur in an organism exposed to tetodotoxin?

A.
decreased appetite due to the production of hormones that indicate fullness
B.
paralysis due to lack of action potentials to signal muscle tissue
C.
increased heart rate due to increased nerve impulses to the heart muscles
D.
blindness due to proteins in the eyes denaturing and losing functionality

Answers

Paralysis due to lack of action potentials to signal muscle tissue- this symptom most likely would occur in an organism exposed to tetrodotoxin.

The symptom occurs in an organism of tetrodotoxin:

Tetrodotoxin is a potent neurotoxin found in pufferfish, porcupinefish and blue-ringed octopus.

Has tetrodotoxin (TTX) in blue-ringed octopuses venom which causes pain and neurotoxic effects(paralysis) by inhabiting signal transduction by nerve cells through sodium channel blockade.

A dose of venom can shut down muscles such as those that keep you breathing and cause death within 30 minutes.

The correct answer is option B.

)B paralysis. Tetrodotoxin works by inhibiting the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions into the neuron. This prevents the nervous system from carrying messages, eventually leading to paralysis

Explanation:

A mother with a blood type of A has a son witha blood type of B. Which of the following are
possible? Select all that apply.

Answers

Answer:

b blood

Explanation:

Final answer:

A mother with blood type A can have a son with blood type B if the father has blood type B and passes on the B allele.

Explanation:

Inheritance of blood types is determined by specific genes, called ABO genes, which are located on chromosomes.

In this case, the mother has blood type A, which means she has two copies of the A allele (IAIA). The father must have given the B allele (IB) to the son, resulting in blood type B.

Therefore, the possible combinations for the son's blood type are IAIB (AB), since he inherited one A allele from his mother and one B allele from his father, and IBIB (B), if the father has blood type B and passed on both B alleles.
