Answer:
-Due to acidic pH of stomach.
Explanation:
Enzymes are generally made up of protein molecules and work at an optimum pH and temperature. This is because at change in pH and temperature leads to denaturation of proteins that cause change in active site of enzyme.
For trypsin, optimum pH is slightly basic as pH (7.5). So, trypsin would become non-functional at acidic pH due to denaturation and loss of active site.
Trypsin is a pancreatic enzyme that works at small intestine as pH of small intestine is slightly basic.Thus, if the trypsin was secreted in stomach instead of pancreas, it would be non-functional as stomach has acidic pH due to stomach acid.
The body protects its self by pathogens is antibody. They are kind like a Marker protein because they cling on to the pathogen and kind of saying like "hey kill this one it's over here". Once that happens a monasteries( I think that's what there called don't quote me though) ears the pathogen and everything dies once that happends

Answer:
DNA packaging is the method to convert long DNA into condensed chromosomes. Histone protein is responsible for basic level packaging of DNA into the nucleosome. Histone proteins are positive in nature that neutralize the DNA's negative charge.
A nucleosome consists of eight histone proteins which wraps around 147 bp of DNA. Each nucleosome has linker histone which forms chromatosome.
The next level of organization is the compaction of nucleosome into approx 30nm diameter fiber due to the attraction between nucleosomes.
Then protein condensin helps in making the 30 nm chromatin fiber to condense more to become a chromosome which is 1000 fold smaller than its original length.
Answer: Water
The ideal percentage for adult women ranges between 45 and 60%, while for adult men between 50 and 65% of the total body. This makes the adult human body to average around 55-60% water. Athletes are recommended to have 5% more body water than the average adult human body range.
