Answer:
Explanation:
Total force = Force due to gravity + Force due to charges
Total force =
r is the separation between particles.
Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs
Mass of a proton (M)= 1.67×10^-27 kilograms
Mass of an electron (m) =9.11 × 10^-31 kilograms
G=6.67 ×10^−11 N⋅m^2/kg^2
k=8.99 * 10 ^9 N.m^2 / C^2
Plugging in values:
Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2
Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2
We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.
Total force = Force due to charges.
F = 2.3 *10^-28 / r^2
r =
Answer:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
Answer:
For plants, the water, sunlight, nutrients, and the space to grow are some key resources.
For animals, important resources include food, water, shelter, and nesting space.

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
