A multi-cellular organism is not an exact copy of its parents because the offspring shares genes of both the parents.
<u>Explanation:</u>
- For a multi-cellular organism to reproduce, they require two parents.
- Characteristics are inherited from both the parents. So, an offspring can't b an exact copy of either of its parents.
- When a unicellular organism reproduce, they make an exact copy of its parent as they originate from only one parent.
- Punnett diagram is used to determine what all traits as organism is supposed to inherit from its parents.
- Chromosomes carry the blueprint of life from one generation to another.
- There are 46 chromosomes with 23 inherited from each parents through the process of mitosis. These chromosome makes up 23 pairs all together.
The discovery of gallium was significant as it confirmed Mendeleev’s predictions and showed the usefulness of his table.
Answer: Option First
<u>Explanation:
</u>
In 1871, Mendeleev prepared a periodic table of all known elements to study their properties. While making the table, he left some places in the table for elements that were yet to be discovered. One of the elements was eka-aluminium.
In 1875, a French scientist Paul Emile Francois Lecoq de Boisbaudran discovered a new element spectroscopically in the course of examining zinc blende. This newly discovered element showed the same properties as predicted by Mendeleev for the eka-aluminium with an atomic weight 69.
Later, the specific gravity of the element was also found to be the same as predicted by Mendeleev i.e. 5.9. After this, Lepoq named the element as Gallium, which confirmed Mendeleev’s predictions and made his periodic table worthier.

Answer:
The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it: If the resistance is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.
