The intensive system of keeping livestock is performed to cater the need of growing population, as people are declining day by day, who can afford to opt for their personal cattle. Thus also known as factory farming, where large amount of cattle are treated with full hygiene and facilities to produce more products like milk and milk products, egg, meat, etc. and with less cost. The basic features of intensive system are as follows:
- The area required for such farming is small as compared to general, thus less land can fulfill the need of large population.
- The method and technology used give employment to skilled workers and follow more rules and regulations to protect livestock from diseases.
- Help in maintaining economical aspects in national level, by increasing production in bulk with comparatively less input.
Genetic engineering:Pros: produces more food, makes organisms more fit, increases knowledge and knowledge is good.Cons: Some say it's: playing God, dangerous due to recombination of DNA, contamination of the gene pool, big pharma could take over the "means of production".
In-vitro fertilization: Pros: Allows people who couldn't have children to do so, increases knowledge and knowledge is good.Cons: Expensive (really expensive), can lead to overpopulation (minor), can be done irresponsibly (minor as everything can be).
Answer:
Yes.
Explanation:
The burning candle is converting chemical energy—stored in the hydrocarbon bonds in the wax—into thermal (heat) and radiant (light) energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light
Answer:
Radioactive labeling is a procedure used to monitor the path followed by a chemical element within a biological system to demonstrate the source.
Hypothesis:
The free oxygen produced during photosynthesis comes from water.
Procedure.
Single-celled algae were placed in four petri dishes containing carbon dioxide, glucose dissolved in Water.
In each box the oxygen was radioactively marked.
1 petri dish with CO2 marked. Experimental groups
2 petri dish with H2O marked. Experimental groups
3 petri dish with Glucose marked. Experimental groups (control)
4 petri dish with CO2 + H2O + Glucose, all marked. (control).
