Answer:C
Explanation:
The arteries are not a cell bc that is too simple a tissue is also too simple its not a system bc arteries are not a lot of organs working together so its C
Answer: The correct answer is nucleotide.
Explanation:
Nucleic acids are the polymer of nucleotides which are attached with each other with the help of phospho-diester bonds.
Nucleotide consists of sugar (ribose in RNA and deoxyribose in DNA), phosphate group, and nitrogenous base (A, T, G, and in DNA; and A, U, G, and C in RNA).
Answer:
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Answer:
Please see below
Explanation:
In such a case, the data will indicate a positive trend towards the outcome predicted in the dependent variable. However, the data has to show a significant difference (as indicated by p value) between the measured variables for it to be a valid support of the hypothesis.
1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
