Answer:
Animals are adapted to the complex chain food since when they were no manufactured to the their food system. Without breakdown this complex food chain can not digest without breakdown.
Explanation:
Earthworm alimentary canal:
- Earthworm have a segmentation of well developed characteristics of all animals.
- The alimentary canal of earth worm as well as flatworm consists of buccal cavity, mouth, esophagus, crop, intestines', gizzard, and anus. The digestion occur extracellular that means the digestion occur outside the cells.
- Cockroach is an omnivores. It ranging from starchy to the sweet things to the paper and clothes etc. It suits its diet. Its alimentary canal consists of Foregut, midgut and the hindgut.
- Both are different in their structure as well as in their alimentary canal.
Answer:
60 grams
60 milliliters of water weighs 60 grams. (or precisely 60 grams.
Explanation:
The process is called interphase
<h2>Regulation </h2>
Explanation:
Operons are the structural unit of gene organisation
If product of regulatory gene binds to the upstream of promoter and induce expression of operon genes, system is called positively controlled whereas if product of regulatory gene binds to the operator and prevents expression of operon genes, system is called negatively controlled
An inducer binds to the repressor and induce conformational changes causing dissociation of repressor from operator therefore in absence of repressor RNA Polymerase binds to the promoter and starts transcription of genes
In some cases, A co-repressor binds to the repressor and activate it as a result activated repressor binds to the operator and prevent binding of RNA Polymerase thus blocks transcription of structural genes
