Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:
Nitrogenous BasePurines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines. In DNA, the bases are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, the bases are adenine, thymine, uracil, and cytosine,
Pentose Sugar
In DNA, the sugar is 2'-deoxyribose. In RNA, the sugar is ribose. Both ribose and deoxyribose are 5-csrbon sugars. The carbons are numbered sequentially, to help keep track of where groups are attached. The only difference between them is that 2'-deoxyribose has one less oxygen atom attached to the second carbon
Phosphate Group
A single phosphate group is PO43-. The phosphorus atom is the central atom. One atom of oxygen is connected to the 5-carbon in the sugar and to the phosphorus atom. When phosphate groups link together to form chains, as in ATP (adenosine triphosphate), the link looks like O-P-O-P-O-P-O, with two additional oxygen atom attached to each phosphorus, one on either side of the atom.
I believe the answer is:
Geosphere and hydrosphere
Biosphere and atmosphere
Hydrosphere and biosphere
Atmosphere and geosphere
Hopes this helps! ^_^
Answer: False.
Explanation:
Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they perform different functions and are structured differently.
The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>
The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>
1. There are trees being reflected on the water. 2. There are plants growing in the water and by the water. 3. The grass in the water. 4. There probably wouldn’t be many plants and there would be holes because they like to dig. 5. Fishing and probably the use of pesticides on the grass because fishing would make the fish population deplete and the pesticides would be toxic to the animals in the ecosystem.
Answer:
It can cause air and groundwater pollution.
Explanation:
All other answers are benefits. Renewable and abundant sources won't run out for a <em>long </em>time, if ever. Reducing greenhouse emissions is good for the environment.
