Polysaccharide formation allows organism to store energy efficiently. The storage form of food in animals is glycogen and in plants it is starch. Both glycogen and starch are polysaccharides of glucose. Many glucose units are linked together by condensation reaction to form polysaccharide. Compared to having several molecules of glucose in a bulk it is better to store it in the form of condensed bulk i.e polysaccharide. Thus polysaccharides which are formed by condensation reaction i.e by the loss of water molecules are easy to store.
Polysacchrides are: a) stored in the form of condensed bulk
b) they are chemically non-reactive
c) they are osmolytically inactive
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.
The answers are;
The muscular contractions are wave-like
The muscular contractions are entirely involuntary
This action is called peristalsis.
It is powered by the expansion and contraction of the smooth muscles present in the esophagus. It is controlled by the sympathetic activity of the autonomic nervous system hence
the movements are involuntary.
The mushroom will get 0.05 kcals of energy units in the end. This is because at each level, you only pass on 10% of the energy, which then results in the mushroom getting only 0.05 kcals by the end.
