<h2>
2nd statement is true.</h2>
Explanation:
Chromosomes are made up of genes and a gene is made up of two copies of alleles. If an organism has two different types of alleles on its chromosomes then it's a hybrid organism else we call it a pure organism/trait.
- Gene could be dominant or recessive.
- A phenotype is the expression of a trait.
- As 'tall' gene is considered to be dominant so so pea plant with even a single copy of 'tall' gene will have a tall phenotype.

Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
