because humans and reptiles and other kind of animals have what's called DNA in nuclei
Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.
Answer:
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes, which is less than one percent of the total are slightly different between people.
Explanation:
Answer:
Great relationship.
Explanation:
There is a great relationship between the structure and functions of animal cells because the structure of cells helps the cell to perform a particular function assign to it. The cells in epithelial tissue are tightly packed together with a very little intercellular matrix. intercellular matrix is a non-living material used to fill the spaces between the cell. Due to this structure, the epithelial tissue forms the covering of all body and helps in protecting the skin.
