The third one is the right answer.
Mutations appear randomly and these mutations can either have possitive, negative or neutral impact on the individual's survival. The environment of the individual amongst other factor determine the net effect of the mutation. For example:
A mutation on a shade plant for bigger leaves would have a possitive impact on the plants survival due to the increase of the photosynthetic tissue area. On the other hand the same mutation on a desert plant would have a negative impact on the plant's survival due to the increase of the leaf area which leads to increased water evaporation off the plant.
Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.
iii) Fragile teeth.
iv) Stiff joints.
Nucleic acids. They contain a phosphate base and a nitrogen group.
False, because nucleotides are what make up a persons DNA so each person has its own unique order.
