Where does the carbon dioxide in breath come from? what organisms use carbon dioxide to survive? research the amount of carbon dioxide generally found in the air and in breath. which has more carbon dioxide? what are some of the other sources of carbon dioxide in air? based on your observations about the acidity of carbon dioxide dissolved in water, what ecological effects could be caused by excess carbon dioxide in the air?

Answer 1:

The carbon dioxide in the breathed out air is a by-product of the process of cell respiration. In respiration, a molecule of carbohydrate is converted into a CO2, H20, and energy which is released in form of ATP.

Answer 2:

All plants belonging to kingdom Plantae and plant-like organism like photosynthesizing bacteria need CO2 to survive. They use carbon dioxide in food making process, photosynthesis.

Answer 3:Amount of CO2 in the air: 0.03%Amount of CO2 in the breath: 4%

Hence it is proved from above statistics that breath has more carbon dioxide than air.

Answer 4:

There are two sources of CO2 in the air. Which are the following:

Human sources: It includes activities of human involvement and release of CO2 artificially as in cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.Natural sources: Release of CO2 by natural processes as in decomposition, ocean release and respiration.Answer 5:The major ecological effect is global warming.As CO2 is known as the greenhouse gas because it gives a greenhouse effect. Elevating concentration of CO2 in air forms a layer or sheath of CO2 over the earth which allows the entry of sun rays and stop it from reflecting back, trapping sun rays around earth increasing the temperature of earth day by day. It also causes plants to provide less evaporative cooling because in high concentration CO2 stomata shrink through which normally evaporation occurs when stomata are open.

Answer from: Quest

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
