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.
Different amino acids means difference DNA sequences, which means they are distantly related.
Further understanding: if you look at identical twins, they are closely related to each other because they have almost the same DNA, which will code for the same amino acids, which will lead to the same phenotype or appearance.
To summarize, the greater the amino acid differences the less related they are and vice versa

Answer:
There are three main types of freshwater biomes: ponds and lakes, streams and rivers, and wetlands. We'll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters, not moving like rivers or streams.

Ssris alleviate symptoms of depression by increasing the<u> level of serotonin at the synapse
.</u>
Answer: Option C
<u>Explanation:</u>
Ssris (Selective serotonin re-uptake inhibitor) is a drug that is been prescribed to the people with depression and anxiety disorders. In the brain the information and messages are passed from one nerve cell to the other.
People with disorders find difficulty in transmitting the information. Hence a drug like SSRI's are prescribed to increase the level of serotonin at the synapse as the nerve cell passes the information through synapse the small gap between the cells.
