Answer: The correct answers are option(b) and(d).
Explanation:
When the lamp was dimmer the resistance offered by the lamp was more which just resist the flow current from the circuit.
(Ohm's Law)
When the Janet decrease the resistance to (R') by sliding the dimmer switch (voltage remained constant). On decreasing the resistance the flow of current in circuit will increase by which light of the lamp will become brighter.
Hence, from the enlisted options the correct options option(b) and(d).
Replication in eukaryotes and prokaryotes
In eukaryotes replication takes place in nucleus.
There are multiple origins of replication.
replication occurs at multiple points along the chromosome.
In prokaryotes replication takes place in cytoplasm
There is only one point of origin of replication
Replication happens at just one point on the chromosome.
Proteins ! they're built from amino acid unlike carbohydrates which are made from monosaccrides
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen
<h2>Answer</h2>
The main human activities responsible for it are:-
1) Fuel combustion, deforestation and industrial production (especially cement factories)
2) Increase in population (humans emit nearly 32 gigabytes of carbon dioxide each year).
3) Imbalance in the carbon dioxide cycle (the ocean does not absorb all of the carbon dioxide, and vegetables cannot convert all of the carbon dioxide into oxygen).
