All the options are correct regarding hypothalamus.
Explanation:
The hypothalamus is the part of the forebrain. The diencephalon is divisible into 2 parts - thalamus and hypothalamus. It regulates various functions of the body.
This is the thermoregulatory center of the body. It gives the signal to sweat during a hot environment and shiver in winter. This maintains the water balance in the body by stimulating the secretion of ADH hormone in the kidney.

Answer:
All of the genes controlling the traits behaved as if they were located on different chromosomes.
Explanation:
Mendel's experiments with pea plants lead to two principles:
- Law of segregation which states that the pair of alleles (for any trait) of each parent separate, meaning that one allele passes from father and another from mother to an offspring.
- Law of independent assortment which states that different pairs of alleles (for different traits) are passed to offspring independently of each other (traits are located on different chromosomes).
Answer:
Explanation: investment in offspring by the parent that increases the offspring's chances of surviving and hence reproductive success at the expense of the parent's ability to invest in other offspring.
Chromosome non-disjunction, anaphase lag and endoreplication
