Answer:
one is made of silk and one is made from branches and anything to keep it together and for padding
Explanation:
the spider makes the webs out of silk and it traps anything that goes through it. the birds make the nests from branches and litter.
Answer;
The enzyme structure begins to break down
intermolecular bonds are broken
enzyme molecules gain kinetic energy.
Explanation;
Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.
Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.
The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.
........... the membrane potential will become more POSITIVE.
A membrane become depolarize when sodium enters the neuron via chemically gated sodium channels, this means that, the membrane become more positive when sodium ions diffuse into the cells.<span />
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
