Give two reasons why dna evidence analysis is an imperfect science
Virty [35]

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.

Which endocrine gland is responsible for the release of a hormone that stimulates T-cell development and proper immune response
Mama L [17]

Answer:

The correct answer would be d. thymus.

The thymus is a specialized lymphoid organ of an immune system.

It serves as the site for training and maturation of T-lymphocytes or T cells.  

It is composed two identical lobes each containing outer region termed as cortex and inner region termed as medulla.

T-cells are first trained and selected in the cortex region via positive selection. In this, T cells which are able to bind to foreign antigens are selected and rest are degraded.

The selected T cells then move in the medulla region where they are selected by negative selection. In this, the T cells which binds to self-antigens are degraded and rest survive to become functional T cells.
