Answer:
D) address issues of pollution
Explanation:
Kyoto Accords is an international treaty that extended from the United Nations Framework Convention on Climate Change (UNFCCC) in 1992. Scientific research has shown result that a continuous increase in CO2 emission will be dangerous to our planet future. So the tenets trying to make a rule that will limit the pollution.
Correct answer: A) The eradication of childhood illnesses
Stem cell are the type of biological cells that have the ability to differentiate into other cell type and can divide to produce different types of cells in the body. They are called regenerative cell which renew itself, they are found in multi-cellular organism.
It can be used as a renewable source of cell replacement and tissue, it can treat serious and common type of disease without organ surgeries and transplantation. It can treat spinal injury, heart disease, diabetes, stroke and osteoarthritis. It has been successfully used in bone marrow transplantation.
Hence, the correct answer would be the eradication of childhood illnesses
Answer:
The correct answer is b. cannot mate and produce viable, fertile offspring
Explanation:
According to the biological species concept, the population of organisms that interbreed with each other and produce viable and fertile offspring is considered as a species.
This means the member of species can interbreed with each other which results in viable and reproductively healthy offspring. So if two animals are not able to mate and produce viable and fertile offspring than those animals are not considered as the same species. Therefore the correct answer is b.
Answer:
1. nucleic acids - these are the molecules also known as genetic material and code for the hereditary characteristics by regulating the production of the proteins.
2. Lipids - Lipids are the hydrocarbon and the major constituents of the cell membrane and molecules like hormones and give energy as well.
3. steroids - Steroids are lipids that have a fused ring structure and do not resembles other lipids however, have the same hydrophobic nature.
4. peptide - when two amino acids react with one another in an acid-base reaction there is a peptide bond form and the new molecule is called peptide and chains of such molecules known as polypeptides.
5. Deoxyribonucleic acid or DNA - It has genetic information code in it as specific sequences, it is used to develop and functions of various living organisms.
6. Ribonucleic acid or RNA - RNA is the molecule that play important role in protein synthesis as it (mRNA) carries the genetic code needed for the creation of proteins to the ribosomes from the nucleus.
7. Monosaccharides - Monosaccharides are the simplest form of Carbohydrates and known as a basic subunit of carbohydrates as these are linked to form complex carbohydrate molecules.
8. Starch - Starch is a carbohydrate found mainly in plants as the storage form of carbohydrates and provides nutrition to various organisms including humans.
9. Isomers - are the ompounds that have the same molecular formula but different chemical structures are called isomers.
10. Carbohydrates - it is the organic molecule and major source of nutrition that is produced by green plants from carbon dioxide and water through the process of photosynthesis.
