Answer:
Birds can keep themselves warn without any external heat source which is not the case with reptiles and amphibians
Explanation:
Birds are able to generate heat means they are endothermic. They generate heat through various metabolic processes. They have air pockets beneath their feathers to insulate their bodies during cold temperatures. Feathers which are modified reptilian scales help birds to streamline their exterior body and structure feathers in a way that it insulates the body.
4 cells would be created after meiosis and each cell would have 7 chromosomes.
<h3>Meiosis</h3>
Meiosis is the division of non-vegetative cells. It is a reductional division during which the ploidy level of the parent cell is halved in the daughter cells.
Thus, a cell with 2n = 14 that undergoes meiosis will produce daughter cells with n = 7.
Usually, 4 daughter cells are produced at the end of meiosis.

The nucleus of an atom is where the protons and neutrons are. The electrons circle around the nucleus.
