Answer: 10 parsecs from earth
Explanation:
Answer:
<u>Option-(B):</u> It is between the layer "C" and "F".
Explanation:
- While the nonconformity is the geological or we can say the environmental effects which represents the specialized for of rock layers being formed in the a variety of patterns inside the planet Earth's structure.
- The process of unconformity indicates erosion and the passage of time in a rock record. While the indications of unconformity is seen in the rock diagram shown above.
You would expect 25 Kcal of energy stored in trophic level 4.
<u>Explanation:</u>
Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.
In this example grass belongs to the first trophic level, producers.
Energy of grass=25000Kcal
Energy transferred to trophic level 2=10% of 25000=2500
10% of the energy in trophic level 2 is transferred to trophic level 3.
Hence energy at trophic level 3=10% of 2500=250Kcal
Energy transferred to trophic level 4=10% of energy in trophic level 3
=10% of 250=25Kcal
Energy to be stored in trophic level 4=25Kcal
Answer:
There are no options in this question, however, the equation can be provided. The answer is:
2Na + 2H2O --> 2NaOH + H2
Explanation:
This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:
Na + H2O --> NaOH + H2
From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.
We have;
2Na + 2H2O --> 2NaOH + H2
Answer:
maybe C because it says different kind of fish that live in one area that is a lake
