Answer:
Nucleus (as nuclear DNA),mitochondrial(mitochondrial DNA) and chloroplasts.
DNA is packed tightly around protein called Histones, in Eukaryotes cells;so that many molecules can easily be held together as chromosomes.
Chromosomes are thread-like structure in nucleus of cells.The histones provide support to the DNA molecule
The part DNA molecule coded for by a polypeptide is GENE, therefore in the nucleus of cells, DNA contains GENE,and the gene and DNA are packed in chromosomes,DNA appears as circular DNA mitochondria
Explanation:
Answer:
The formula is 2n - 2
Since n is 30
= 2(30) - 2
= 60 - 2
= 58
A mutant nullisomic version of this organism would have 58 chromosomes.
A diploid cell missing both copies of the same chromosome exhibits a nullisomic condition or a cell or individual with one chromosomal type missing. Humans having this condition will not live.
Answer:
facilitated diffusion
Explanation:
Facilitated diffusion is the process of movement of molecules or ions across a biological membrane via specific transmembrane integral proteins. Carrier proteins and channel proteins are involved in facilitated diffusion. The movement of molecules and ions in passive transport occurs due to a concentration gradient.

The answer is nares. Breathing describes the process of inhaling and exhaling air. The exchange of gases between living cells and the environment is a process known as respiration, consists of the respiratory. The respiratory system, which controls breathing and respiration, consists of the respiratory tract and the lungs. The nose is the only external part of the respiratory system. It is made of bone and cartilage and is covered with skin. The two openings to the outside, called nostrils, allow air to enter or leave the body during breathing.
