Answer:
Your answer is B) 2.0 g/.
Explanation:
Utilize this formula: p=m/V (density (p) is equal to mass (m) divided by volume (V).)
Answer:
A) Avoid staying outdoors when the sun is the strongest.
Explanation:
The sun can cause skin cancer if one is exposed to it for too long, so they should not go in the sun when it's the strongest.

6.97* 10 to the power of 7 = 69700000
Answer:
The exception is d) Inactivation of phosphodiesterase
Explanation:
In the presence of light:
a) The membrane potential of the photoreceptors is hyperpolarized, causing a reduction in the amount of neurotransmitter released by the photoreceptor terminal to the postsynaptic neurons
b) Sodium ions accumulate outside the plasma membrane and the receptor potential takes a form
of hyperpolarization 6. This change in membrane potential leads to the closure of calcium channels. The end result is a decrease in the secretion of the neurotransmitter glutamate by the photoreceptors
c) Visual transduction or phototransduction is the process by which a light photon generates a nervous response in the photoreceptors
d) As a consequence of phosphodiesterase activation, degradation of a molecule called cGMP (guanosine cyclic monophosphate) is stimulated
Hello!
Ions are charged particles, that explains why they have either a positive or negative charge. Since electrical signals contain charges, that also explains why they are often based on ions. Your answer would be D!
