Answer:
Large bodies of water take more time to change temperature than land.
Explanation:
Large bodies of water take more time to change temperature than land because more energy is required by water to in order to make the water evaporate, therefore, water takes more time to change its temperature as compared to the land. Water also has a particular temperature which takes more time in order to be changes. Land is not transparent, therefore, heat or cold has no need to be get penetrated in it, whereas, water is a transparent medium where heat and cold is required to get absorbed till its deep end, so it takes more time for water to change its temperature as compared to land.
D. because the infant's kidneys cannot clear large amounts of urea every day
Answer:cell 9 is not missing any organelles compared to cell 1.
Cell 2 would not function normally because it lacks the mitochondria which is the powerhouse necessary for energy production & hence growth & survival.
Cells 4 & 7 lack the rough endoplasmic reticulum responsible for protein formation hence amino acids which are the building blocks of life will not be produced.

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.
