2 questions..please help (biology) ?
when organisms break the bounds of organic compounds that organisms can..
A. use the smaller molecule to plug the gaps in the cell membrane to slow diffusion.
B. excrete smaller amounts of solid waste materials during vigorous exercise
C. obtain energy or reassemble the resulting materials to form different compounds.
D. use the energy obtained to digest molecule produced by respiration that uses oxygen.
#2
The production of energy-rich ATP molecule is the direct result of
A. copying coded information during the process of protein synthesis
B. breaking down starch by the process of digestion
C. releasing the stored energy of organic compounds by the prosses of respiration.
D. recycling light energy to be used in the process of photosynthesis.
1. the answer is C. The other answers are nonsense.
2. the answer is again C. Cellular respiration is the process of “burning” organic compounds in the presence of oxygen to produce ATP.

The Produce Contamination Problem: Causes And Solutions $95.99 This book is organized into five sections beginning with an introduction in which the problem is described in terms of the number and size of produce related outbreaks the commodities involved and the human pathogens involved. The introduction also documents the failure of conventional sanitizing treatments to assure microbiological safety examining the problems of microbial attachment. The second section reviews methods of identifying a contamination source (epidemiology trace back strain identification location of Source) and then focuses on the various sources of microbial contamination (water manure airborne dust wildlife human activity) and where in the crop production sequence they might result in contamination. In the third section some of the commodities associated with major outbreaks (leafy vegetables tomatoes cantaloupes apples berries sprouts) are examined to determine what characteristics make them especially vulnerable to contamination. The fourth section then addresses means of avoiding produce contamination through use of Good Agricultural Practices and recommendations in FDA and industry guidance documents. Regulatory actions (recalls restrictions on imports) to safeguard the public from potentially hazardous products are described. Coverage includes policy and practices in the US Mexico and Central America Europe and Japan. The fifth section examines current technologies for reducing human pathogens in fresh produce including disinfection rapid methods for detecting contaminants irradiation gas-phase application and best practices acceptable to organic growers packers and processors. *Addresses foodborne contaminations from a prevention view providing pro-active solutions to the problems *Covers core sources of contamination and methodologies for identifying those sources *Includes best practice and regulatory information |
