Photosynthesis stores
energy in organic compounds. This organic compound is glucose. The reactants
that are used by photosynthesis to make this organic compound are the carbon dioxide and water (which are abiotic factors).
Glucose is then used as an energy source
by the plant to power its biological proceses.
Answer:
Lipids are long chains of carbon and hydrogen molecules. They are oily or waxy.
Proteins are large molecules consisting of one or more chains of amino acids. They provide structure and support for cells.
Carbohydrates are mainly sugars and starches that the body breaks down into glucose. They are the main source of energy in animals.
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information.
Explanation:
Answer:
A bacteriophage is a type of virus that attacks bacteria. In the lytic cycle, the virus hijacks the cell machinery of the bacterium that it has infected. In the lysogenic cycle, the viral DNA is incorporated into the bacterial DNA.
Explanation:
Its a type of virus.
Answer: The parasympathetic nervous system and sympathetic nervous system play opposite roles
Explanation:
To ensure a stable internal environment (homeostasis) is achieved, the parasympathetic nervous system (PNS) and sympathetic nervous system (SNS) play OPPOSITE roles.
The PNS dominate during relaxed periods and stimulates the
- liver to break down glycogen
- constriction of bladder to pass out urine
- increases heartbeat
- dilate pupils etc
The SNS, in contrast dominate in times of emergency or stressful periods and do the EXACT opposite of the processes mentioned above.
Thus homeostasis is maintained
a) Pyruvate is a three-carbon molecule, so two molecules can be produced from each molecule of glucose. In total, from 4 molecules of glucose that enter glycolysis, there will be produced eight molecules of pyruvate.
b) PA becomes Lactic Acid instead of Acetyl CoA in anaerobic respiration (that is in auscense of oxygen), particularly when the cell carries out lactic acid fermentation, which is what can happen in the mitochondria of muscle cells when faced with a very demanding stimulus.
