Answer:
The best answer prompt you should use to avoid copying is that most of the world uses fossil fuels as energy for transportation and that to get rid of using it would take centuries as well as finding a way to provide energy with a renewable source. The use of fossil fuels would negatively affect the biodiversity in neighborhoods and the surrounding environments because the usage of fossil fuels causes pollution to the air, water, and the atmosphere that can lead to other problems.

Key developments in blood transfusion techniques
• Animal experiments over the years 1900-1916 gradually enabled transfusion to become the routine technique it is today. The key developments were:
• George Crile (1907) perfected the technique of transfusion from artery to vein using dogs, and described its application in 32 patients.
• Hustin (1914) showed that addition of sodium citrate could prevent blood from clotting and that citrated blood could be safely transfused into dogs.
• Richard Lewisohn (1915) determined the maximum amount of citrate that could be transfused into dogs without toxicity and thus determined the optimum concentration that could be added to blood for the best anticoagulant effect.
• Weil (1915) showed that citrated blood could be stored for 2 days and still be effective when transfused into guinea-pigs and dogs which had lost blood.
• Rous and Turner (1916) used rabbits to demonstrate that, with certain additives and proper treatment, citrated blood could be stored for 14 days and still be successfully transfused.
Through these animal experiments, the prolonged storage of blood without clotting thus became possible, so enabling the establishment of blood banks, and blood transfusion as a routine procedure.
Answer:
Heterotrophs obtain chemical energy for their survival by eating plants and animals.
Explanation:
- The chemical energy that organism need comes from food. They break this food down to obtain energy.
- Depending on their source of nutrients , they are classified into: Autotrophs and Heterotrophs.
- Autotrophs use sunlight and photosynthesize to produce their own food. They are often known as producers.
- Heterotrophs are beings that can't prepare their own food and consume other organisms to obtain energy.They are also called consumers.
- Examples include: Animals, fungi,etc.
