I would say they need to look to Linneaus System of Classification, because he devised the taxonomical system of class, order, phylum, species variety, etc.
<u>Phenylketonuria</u>
Explanation:
Phenylketonuria (PKU) is a type of a rare inherited metabolic disorder.
Etiology: PKU results from excessive accumulation of the amino acid phenylalanine in the body. Normally, phenylalanine will be converted to tyrosine (forms neurotransmitters) by the action of the enzyme phenylalanine hydroxylase.
Among people with PKU, a defect in the PAH gene which codes to synthesize this enzyme occurs which leads to the absence of this enzyme. So the phenylalanine which is normally present in dietary protein is not metabolized and gets accumulated. This gene is inherited by the child only if both the parents are with the defective PAH gene.
Symptoms: Stunted growth, behaviroral disturbances, learning difficulties, seizures, tremors etc.
Treatment: Basic treatment is to follow a diet which limits dietary sources of phenylalanine. High protein foods like meat, egg should be avoided. Children can be given PKU formula to supplement their nutritional needs.
The plant cell is the smallest living structure and constituent unit of all plants. Its size and shape vary by function. It is composed of several organelles, all useful to its activity.
The right answers are: (the numbers are in the picture).
1 refer to a vacuole.
2 refer to a cell wall (if you see closer, the arrow is aiming the green layer, the yellow one is the cell membrane).
3. refer to a chloroplast.
4. refer to mitochondria.
Answer: Plants use Carbon Dioxide to produce sugars and energy, so you could expect the high-energy sugars to be depleted as the sugars are used to produce energy, and the sugars cannot be replaced as fast as they are being used.
The disadvantage of having imformation at your fingertips is that not all of information could be true but only mere ideas or theories and that having alot of information can be overwhelming to the point where you can process so much information you might forget about the important things you come across for some propaganda trying to get your attention
