First answer gets brainly.<br> Explain why the moon can be seen from Earth.
Goryan [66]

Answer:

We see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon orbits once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth.

A spheroidal bacterium with a diameter of 1 mm contains 2 molecules of a particular protein. What is the molar concentration?
creativ13 [48]

Answer : The molar concentration is, 6.35\times 10^{-18}mol/L

Explanation :

First we have to calculate the moles of protein.

\text{Moles of protein}=\frac{\text{Number of molecules of protein}}{\text{Avogadro's number}}

Number of molecules of protein = 2 molecules

Avogadro's number =  6.022\times 10^{23}molecules/mol

\text{Moles of protein}=\frac{2\text{ molecules}}{6.022\times 10^{23}molecules/mol}=3.32\times 10^{-24}mol

Now we have to calculate the radius.

Radius = \frac{Diameter}{2}=\frac{1mm}{2}=0.5mm=5.0\times 10^{-4}m

Conversion used : (1 mm = 0.001 m)

Now we have to calculate the volume.

V=\frac{4}{3}\pi r^3

V=\frac{4}{3}\times 3.14\times (5.0\times 10^{-4}m)^3

V=5.23\times 10^{-10}m^3=5.23\times 10^{-7}L

Conversion used : (1 m³ = 1000 L)

Now we have to calculate the molar concentration.

Concentration=\frac{\text{Moles of protein}}{\text{Volume}}

Concentration=\frac{3.32\times 10^{-24}mol}{5.23\times 10^{-7}L}

Concentration=6.35\times 10^{-18}mol/L

Thus, the molar concentration is, 6.35\times 10^{-18}mol/L

  3. (a)
  4. (b)
  5. (d)

  1. (d)

Explanation:

1.

I saw the similarity that there are 7 periods in a periodic table and 7 days in a week.

2.

The periodic table tells us both the symbol and atomic number of the elements.

3.

days as there are 7days in a week.

4.

vertical columns are called groups.

5.

seeing the periodic table we can locate it postion that is group 16 period 2.

CONCLUSION :-

1. all the given points tell the properties of periodic table.

What could have caused the<br>moon jelly population to<br>increase?​
evablogger [386]

Answer:

Explanation:

To reproduce, organisms need to release energy from energy storage molecules. If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase.
