Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.

Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.

Answer:

Popypoidy mainly occurs in the plants when there is total non-disjunction of sister chromatids occurs during the meiosis of gametic cells. So as before the meiosis the number of chromosomes doubles and after meiosis every cell get half the number of chromosome so after segregation failure autopolyploidy occurs in plants.

Triploid condition can also be seen in animals when two sperms fertilize one ovum. So, in this case, the chromosome number reaches to 69(23+23+23) which means chromosome number become 3n.

Answer:

can ,synthesize specific proteins

Explanation:

Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.

They are transported in the circulatory system of the body

The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.

For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.

When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.
