B Phytoplankton - Zooplankton - Arctic cod - Ringed sal
Explanation:
The food chain that describes the path through which energy takes will be phytoplankton-zooplankton-Arctic cod-Ringed sal. Energy moves in the ecosystem from producers to primary consumers then secondary and tertiary consumers.
- Autotrophs are those organisms that manufacture their own food. The use chemical substances from the environment to produce their nourishment which serves as the source of energy for the whole ecosystem too.
- Autotrophs are the producers in any ecosystem and they are usually the plants.
- The phytoplankton is an autotroph.
- Next up are the primary consumers that takes up the produced food by the autotrophs for their own nourishment. In the chain above, the Zooplankton is the primary consumer.
- The secondary consumer that feeds on the zooplankton is the Arctic cod.
- The tertiary consumer is the Ringed Sal which feeds directly on the Arctic cod.

Answer:
10
Explanation:
Binary search's runtime is proportional to log (base two) of the number of list elements.
Answer:
Major organic products are- (a) propan-1-ol and (b) 2-methylpropan-2-ol
Explanation:
methyl magnesium bromide gives nucleophilic addition reaction with carbonyl group. Because methyl magnesium bromide is a strong nucleophile and carbonyl group is a strong electrophilic center.
Propanal contains an aldehyde group and propanone contains a ketone group. hence they both give nucleophilic addition with methyl magnesium bromide.
Dilute acid is added to protonate the alkoxide produced during nucleophilic addition.
Reactions are shown below.
The energy required is Ionization energy

Required Answer :- </h2>
- In the question it is asked how many numbers of protons are present in a sodium atom.
- We know that the atomic number of sodium is 11.
- Sodium atom means it is in its neutral state, the neutral sodium atom has no charge on it.
- We know that the atomic number of an element is always equal to the number of protons for the particular element.
- Therefore the atomic number of sodium is 11 and the number of protons in sodium are 11.
<h3>Additional information :- </h3>
- If we know the atomic number of an element then only we can find the number of protons, neutrons and electrons present in it. The number of electrons in an element is equal to the atomic number of the respective element
- The atomic weight of the sodium is 23.
- The number of neutrons in sodium = Atomic weight of sodium – number of protons in sodium
= 23 – 11 = 12.
- So, the number of neutrons in sodium is equal to 12.
- The number of electrons in sodium is equal to the atomic number of sodium. Then the number of electrons in sodium is equal to 11.
- Therefore the number of protons, neutrons and electrons in sodium are 11, 12 and 11 respectively.
