Classwork 25/11
1.peristalsis : the waves of contractions and relaxations of longitudinal and circular muscles to move food forward
2.Deficiency of fibres: Constipation & increased risk of bowel cancer
3.Balanced diet: the intake of all nutrients in right amounts according to gender, age, and physical activity

5.Children need more protein for growth and tissue repair
6.Female need more iron to replace the blood loss in the menstruation cycle monthly period
7.Pregnant women need more calcium to strengthen the bones and teeth of the embryo

8.DNA structure


9.DNA is important because it contains the genetic information that are passed down to generations
by inheritance help in the protein synthesis and contain specific sequence of bases
10. mRNA IS THE COPY OF GENE FOUND IN DNA formed by trancription
mRNA moves through the nuclear pores to the ribosomes in the cytoplasm
mRNA attaches to the ribosomes where translation occur
Messenger RNA has a specific sequence of bases which codes for a specific
sequence of amino acids, ribosomes assemble amino acids into poly peptides which
fold into 3-D shape
