Heaps and heaps and heaps and heaps of them!
Answer:
Fertilizers are the chemicals that are applied on the agricultural crops to increase the yield of crop and protect them from harmful pests. The fertilizers are rich in nitrogen, phosphorus and potassium.
Karen and Jimmy growing tomato to conduct the research. They conclude that large amount of fertilizer is helpful for plant growth. This is wrong because high fertilizer can decrease the plant growth and may cause the death of plant. The fertilizers are required in the exact amount in the plants and there inappropriate level inhibits the plant growth.
C applies as the kidney must excrete salt in order to get rid of excess water. (Water chases salt) if there is too much salt in the body the urine will be much more concentrated then if the body had too much water. Glucose may kbly be excreted if there are problems with the kidney- some diabetics pee out glucose. D applies to some degree- salt will still be excreted but in very dilute amounts- as the water must chase something in order to be excreted.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
MRNA carries a transcript of the needed amino acids to tRNA and then to the rRNA ribosomal component.
