Scientists have engineered bacteria to produce human proteins, such as human growth hormone (hGH) used to help treat dwarfism. S
Zigmanuir [339]

Answer:

Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.  

When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.  

Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.

A heron, a large wading bird, is hunting in a pond that contains three types of prey: fish, frogs, and snakes. All three types o
r-ruslan [8.4K]

The preferred prey item would be frogs.

What is optimal foraging theory?

It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.

In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.

In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.

In other words, frogs would be the most preferable prey.
