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.

. You have constructed four different libraries: a genomic library made fromDNA isolated from human brain tissue, a genomic libr

aksik [14]

Answer:

A) Brain genomic library and muscle genomic library.

B) Brain genomic library and muscle genomic library - overlap completely.

Human brain cDNA library, and a human muscle cDNA library and other library is partially overlap.

Explanation:

A) The genomic library contains the whole genome content of the organism whereas cDNA library contains the coding genome of the organisms. Brain genomic library and muscle genomic library will constitute the all the genomic sequences of brain and muscle. The cDNA library is prepared from the mRNA and the coding regions are present in this library.

B) The overlapping in the genome library might occur due to the common sequences present in the genome. Brain genomic library and muscle genomic library might completely overlap with each other as they have more sequence common among each other. All the other library may be partially overlap with each other as they have some common DNA sequences and neither library can have unique sequences.

Animal Diversity Lab Activity:

Olenka [21]

The phylogenetic tree of organisms within the animal kingdom include characteristics below:

Ancestral protists
Tissues
body symmetry
Germ layers
Body cavity
Porifera
Platyhelminthes
Nematoda
Annelida
Mollusca
Arthropoa
Echinodermata
Chordata

<h3>What is phylogenetic tree?</h3>

A phylogenetic tree simply refers to a branching diagram or a tree showing the evolutionary relationships among various biological species of both plants and animals based on their similarities and differences; either genetically or physically

Generally, animals; be it vertebrates or invertebrates has the few characteristics below:

All animals are multicellular organisms
Animals are also heterotrophic, meaning; they depend on other organisms for food or they obtain their energy by consuming energy-releasing food substances.
Animals typically reproduce sexually.
All animals are also made up of cells that do not have cell walls.

In conclusion, the phylogenetic tree of organisms within the animal kingdom include all characteristics mentioned above
