<h2>Answer:</h2>
Chromosomes are structures present in the nucleus of the every organism's cell and it is the DNA packed with histones proteins.
Explanation:
DNA deoxyribo nucleic acid is the nucleotide sequence which is the blue print of the structural and functional characteristics of the whole organism.
Nucleus of the call is very small to be contain the DNA of cell. So DNA is present in the condense form by wrapping around the histones proteins which is known as cell division.
At the time of cell division, it is present in chromosomal form to equally divide the genetic material.
Sheeps possibly should be able to run quickly, to have a good sense of smell and to have quick reflexes.
These three sheeps are desirable for sheep as they enhance their survival capabilities. These traits are passed on to the new generation through reproduction.
Some fruits—for example, the dandelion—have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.
Answer is chemical energy.
The fuel used in car is petroleum product which is a fossil fuel. Petroleum products such as petrol or diesel are chemical compounds in which chemical energy is stored in their bonds. When these compounds undergo chemical reactions, resulting in breaking of bonds and releasing energy. When ignition of a car is on, the energy is released when chemical bonds are broken. The released energy is carry out work in the car system.
The term for this idea was "The Spontaneous Generation Theory."
