Answer: Option C) The unicellular organism creates a new organism.
Explanation:
Cell division involves the multiplication of cells whereby one cell divides into two daughter cells or offsprings, two divides into four and so on.
In unicellular organisms, cell division could be by the following ways:
- Binary fission in Ameoba
- Budding in Hydra
- fragmentation in Sponges.
Thus, each of these unicellular organisms divides to give rise to new organisms that are similar to their parents
Answer:
Increases
Explanation:
As the number of carbons in the hydrocarbon increases, the boiling point of increases and volatility reduces.
The increasing number of carbon atoms increases the molecular mass and this will eventually lead to a higher boiling point.
- With increasing chain length, hydrocarbons tends towards liquid and solid phases.
- This increase leads to a greater intermolecular interaction in the compound.
- Intermolecular forces determines the boiling point of hydrocarbons.
- This is why gasoline is easily combusted compared to lubricant oil.
Answer:
d per the definition......
Mass of iodine solid produced = 1.6 g
Iodine solid has a molecular formula : I2
Atomic mass of iodine = 126.904 g/mol
Therefore, molar mass of I2 solid = 2* 126.904 = 253.808 g/mol
Number of moles of a given substance is the ratio of its mass to the molar mass
# moles of I2 solid = mass of I2 solid/molar mass = 1.6 g/253.808 = 0.00630 moles
Hence, the # moles of iodine solid produced is 0.00630 moles
