Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Animal cells have centrioles and plant cells don't have this.Animal cells divide everywhere and all the time but plant cells divide in a specialized region called the meristems.
<u>Explanation:</u>
The mitotic cell division occurs in both plants and animal cells. The process involved in the formation daughter cells in cytokinesis stage makes the difference between animal and plant cell division. The animal cells forms a furrow and the daughters cells forms in the cytokinesis stage. The plant cells will not form furrow since their cells are rigid.
Centrioles are present in animal cells. centrioles are absent in plant cells. The cell division occurs at every place and any time in an animal cell. In plant cell the division occurs only in meristems which is a specialized region in plant cells.
Answer:
Regulation of intake is governed by thirst receptors that pick up signals of dehydration and return the body to a rehydrated state.
Explanation:
The state of hydration in someone's body is given by the plasma osmolarity values (the ratio of solutes to water in blood plasma). After regular activities that involve the loss of water, such as urination and sweating, happen, the blood begins to concentrate and the osmoreceptors located in the hypothalamus are triggered to generate a response that leads to water intake.
Animalia are heterotrophs while plantae are autotrophs
