7 0

The arrangement of leaves on a stem shows the differences in trees , and this helps identify a tree during the growing season. The presence or absence of lobes on a leaf can also identify the species of a tree. The leaves also vary in shape, which indicates the position that it has on the tree. Also, some leaves are simple leaves, and others are compound leaves. Vein patterns and leaf edges can also indicate the type of tree that a leaf came from.

question 8

DNA is copied into mRNA during the process of Transcription

Transcription is the process by which information in the strand of DNA is copied into new molecule of messenger mRNA.
The mRNA formed is a complimentary to DNA strand whereby replace of C with G, and A with U and T with A.

Question 9

Translation occurs in the ribosome , the organelle responsible for building proteins.

Ribosome are responsible for protein synthesis.
They receive messenger RNA sent from the nucleus and build protein.
translation has three steps that is

initiation - ribosome assemble around the target mRNA.
elongation- The tRNA transfer amino acid to tRNA corresponding to the next codon.
Three phases of translation initiation polymerase bind to DNA strand and move along until the small ribosomal subunit binds to DNA.

28) The graph below shows how the activity of an enzyme changes at different temperatures.

puteri [66]

Answer:

d) The enzyme changes shape and can no longer speed up the reaction

Explanation:

Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
