Answer:
- <u>Oxygen is combined with the carbon atoms left from the glucose molecule.</u>
Explanation:
Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.
Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product .
I would say the temperature of a biome, and the precipitation (rain, snow, etc.). For example, a desert can obviously be classified for its immense amounts of heat and lack of rain. Hope this helps.
Answer:
1) The ray population increased.
Explanation:
Two studies on sharks released this month reveal the populations of great whites in the Atlantic and Pacific Oceans are on the rise after a period of harsh decline.
The reports, published in the journal PLOS ONE, indicate the number of great white sharks has rebounded since the population was decimated by overfishing in the 1970s and 80s.
“The good news is that white sharks are returning to levels of abundance,” George Burgess, director of the Florida Program for Shark Research who led a study about great white populations in the Pacific, told the Christian Science Monitor.
The National Oceanic and Atmospheric Administration (NOAA) conducted its study on the great white population along the western North Atlantic, and credits the United States’ 1997 ban on hunting the shark species for allowing the population to replenish.
Answer:
Explanation:
. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.
5.Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Answer:
The weakest of all scientific findings are given by case studies.
Explanation:
Case studies are observational or descriptive studies focalized on the analysis of a particular object (an individual, place, event, etc.) in a specific situation. Beacuse of its descriptive nature, it does not provides information about cause-effect relationships and does not consider the effect of random variations. It is the weakest of all scientific findings.
Correlational studies involves measurements of at least two different variables and try to identify if there is a specific relationship between variables, it means if there is a specific trend in the variation of one variable as a response to the variation in the other one (for example, when the temperature of a given solution increases, the solubility of the solute also increase). Although this kind of studies does not provides information about cause relationships, the trend between variables are well stated.
Experimental studies are the ones in which a researcher makes sure of providing a controled environment and manipulates a particular variable to see responses of one or more different variables. These studies provides well supported information.
Epidemiological studies the purpose to analyze all the factors involved in an epidemic (causes, incidence, evolution, etc.). It includes observational and experimental studies that complement each other. Because of the importance of these reasearch on public health, their scientific findings are well stablished and supported.
Summarizing, the weakest of all scientific findings are provided by case studies.
