CellRespLab-Handout BIO 101

I'm studing Cellular Respiration.  We did a lab.  We had technical difficulties... our CO2 gas sensor wasn't working properly.  So I am curious, what trends SHOULD I have seen.  We compared the CO2 output of bean sprouts vs mealworms.  We tested at both room temp (27 degrees C) vs cold temp (15 degrees C) for both the mealworms and bean sprouts.  I need to know the trends I should have seen, ie. does an animal or plant produces more C02 and why?  Also does the the cool temp make the reduction in CO2 production?  Thank you.

Nighttime loss of NOx in the lower troposphere proceeds by: NO + O3 --> NO2 +O2 (1) NO2 + O3 --> NO3 + O2 (2) NO2 + NO3 + M <--> N2O5 +M (3) N2O5 --> 2HNO3 (in aerosol H2O) (4)    Let NO3* represent the chemical family composed of NO3 and N2O5, ie, [NO3*]=[NO3]+[N2O5]. Calculate the lifetime of NO3* at night.

Chronic exposure to neonicotinoids reduces honey bee health near corn crops Experiments linking neonicotinoids and declining bee health have been criticized for not simulating realistic exposure.  Here we quantified the duration and magnitude of neonicotinoid exposure in Canada's corn-growing regions and used these data to design realistic experiments to investigate the effect of such insecticides on honey bees.  Colonies near corn were naturally exposed to neonicotinoids for up to 4 months - the majority of the honey bee's active season.   Realistic experiments showed that neonicotinoids increased worker mortality and were associated with declines in social immunity and increased queenlessness over time.  We also discovered that the acute toxicity of neonicotinoids to honey bees doubles in the presence of a commonly encountered fungicide.  Our work demonstrates that field-realistic exposure to neonicotinoids can reduce honey bee health in corn-growing regions. Which of the following…

Identification and Distribution of C3 and C4 Grasses in Open and Shaded Habitats in Sao Paulo State, Brazil1 Carlos Augusto Klink and Carlos Alfredo Joly Departamento de Botanica-Instituto de Biologia, Universidade Estadual de Campinas, C.P. 6109-Campinas-SP-Brazil- 13.100 ABSTRACT The photosynthetic pathway of grasses collected in several vegetation formations in Sao Paulo State, Brazil, was identified by leaf anatomy. Of the 78 species collected, 48 sun species and seven shade species possessed the C4 pathway. Twenty-three species possessed the C3 pathway, of which three were sun species and 20 were shade species. This result indicates that the C4 species are more abundant in open habitats and C3 species in shaded habitats. The data also show the taxonomic distribution of the photosynthetic pathways. All genera of the collected species are exclusively C3 or C4, except Panicum which has both C3 and C4 species. RESUMO A via do metabolismo fotossint6tico de…

Investigation: Suppose you accidentally introduce a small plant-eating beetle into your self-contained ecosystem. At the end of the three weeks of your experiment, you might notice that the beetle has grown a little bit. Where would the increase in mass of the beetle come from?

Two plants are in a set-up wherein they are covered by plastic. Plant 1 had a transpiration rate of 1.15 while Plant 2 had a transpiration rate of 1.86.  Your primary goal is to conserve water. Based on the given, which plant is adapted more naturally in forests wherein there is a high humidity?

The number of twigs on your tree: 154,000 twigs Based on transpiration measurements that we have made in previous years; each twigtranspires about 3 grams of water per hour on a warm spring day. That is, multiply your tree’s twigs by 3. This is a rough average for all sides of the tree (the south side, exposed to the sun, and the north side, with indirect light.) Calculate the number of grams of water per hour that your tree transpires. ____________g/hr   Now convert your grams of water to kilocalories. Remember that the evaporation of a gram of water uses about 0.6 kilocalories of heat, which comes from the air. _____________ kcal/hr   Assume that a day is 10 hours long and a month is 30 days. How many kilocalories per month does your tree account for? _________ kcal/mo   How many kilowatt hours of electricity would it take to have an air conditioner use this number of kilocalories? One kilowatt hour takes about 860 kilocalories of evaporation. Transpiration in your tree…

Combining BioEnergy with Carbon Capture and Storage (BECCS) offers theprospect of energy supply with large-scale net negative emissions and in most of the lower RCPs is required to stay below 2 degrees of global warming. But this entails challenges and risks associated with the upstream large-scale provision of the biomass that is used in the CCS facility as well as those associated with the CCS technology itself. In no morethan 1 page (excluding diagrams) discuss the potential role of BECCS in reducing global greenhouse gas emissions from conventional fossil fuel power stations and what issues or barriers need to be addressed to enable this. Some of the points to be addressed include:i. To what extent the technology has been proven at an appropriate scale.ii. What incentives (e.g. what level of carbon price) would be needed to drive the investment needed.
