Answer:
True
Explanation:
Mosquitoes are cold-blooded creatures, therefore they can’t regulate their body heat and their temperature is essentially the same as their environment. Temperature and mosquito activity goes hand in hand with the insects flourishing in moist, relatively warm environments, functioning best at 80°F. Once the temperature lowers to about 60°F they become lethargic and anything below 50°F they find it hard to function at all.

Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
Answer:
giraffes necks consists a tall bone like structure called notochord which gives support to the skeletal system like how do we have backbone
