Why is the phase of the moon important for a lunar eclipse to occur?

Biology
1 answer:
cestrela7 [59]3 years ago
8 0

Answer:

The moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. ... During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon.

Where do the cells project through the ethmoid bone and synapse with the olfactory bulbs?
VikaD [51]
<span>The afferent nerve fibres of the olfactory receptor neurons transmit nerve signal about odours to the CNS. From the olfactory mucosa (inside the nasal cavity), the nerve travels up through the cribriform plate of the ethmoid bone where the fascicles enter the olfactory bulb<span>. The olfactory</span> bulb is a structure which contains specialised neurones, called mitral cells and the nerve fibres synapse with those mitral cells, forming collections known as synaptic glomeruli. From the glomeruli, second order nerves then pass into the olfactory tract which runs to the CNS (</span>primary olfactory cortex).

maksim [4K]
The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.

Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) Wha
lana66690 [7]

Answer: 21850.42mmHg or 28.78atm

Explanation: From the equation of the reaction, 2 moles of sodium reacts with 2 moles of water to produce 2 moles of NaoH and 1 mole of hydrogen gas at s.t.p.

molar volume of gas at s.t.p. = 22.4dm^3,

standard temperature = 0°C or 273K,

standard pressure = 760mmHg or 1atm,

molar mass of Na = 23g;

volume of the container= 20L or 20dm^3

From the equation, 2 moles or 46g of Na produces i mole or 22.4 dm^3 of hydrogen.

Therefore, 1kg or 1000g of Na will produce 22.4 * 1000/(46)= 486dm^3 of hydrogen.

To find the pressure of the gas produced, the formula P1V1/T1 = P2V2/T2

P1= 760mmHg, T1= 273K, V1 (initial volume of gas)= 486dm^3, T2=50.0°C or 50+273K= 323K, V2( final volume of gas= volume of vessel)=20dm^3  P2=?

P1= P1V1*T2/(V2T1)= 760mmHg * 323/(273)= 21850.42mmHg or 1atm*21850.42/760= 28.78atm
