Answer:

All substances have characteristic physical and chemical properties. Physical properties are those that can be observed with the senses without changing the identity of the substance. Chemical properties describe how a substance can be changed into a new substance. Physical and chemical properties, such as color, density, boiling point, solubility, conductivity, and flammability,

are always different between substances

Explanation:es

Both physical and chemical properties differs as physical properties entails those characteristics that are visible while chemical properties entails chemical constituents that makes such substances

What is the role of tRNA?
nirvana33 [79]

Answer:

The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation

Explanation:

tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to  its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.                

tRNA then moves to the P site and a new tRNA bind to the A site  of ribosome and brings a new  amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA  recognizes a termination or nonsense codon

TRUE OR FALSE?
Harrizon [31]
<h2>Answer:</h2>

I believe the correct answer is FALSE.

<h2>Explanation:</h2>

Innate immunity is a fast acting response to confront a pathogen but does not keep memory. It is initiated and carried out by cell and can be refered to as cellular immunity lasting for a short term.

<h2>Further Explanation:</h2><h3>Innate Immunity:</h3>

This is the first line of defence and involves only cells. It lasts for a short period usually around 12 hours. It includes physical barries. The cells involved are: epithelial cells, dendritic cells, plasma proteins and natural killer cells. All the cells involved are macrocytes. It functions to recognize and attack the pathogen before the second type of immunity called adaptive immunity sets in. It usually is also non specific and responds generally to any pathogen.

<h3>Adaptive Immunity:</h3>

It is a much more longer lasting type of immunities and has memory. It has a combination of cells and humoral components. It involves Naive B cells which are triggered to release antibodies known as Immunoglobulins depending on the cause of the trigger. Immunoglobulins include IgG, IgM, IgA, IgG  and IgD and are usually Y-shaped. Additionally, it involves Naive  T cells that are activated into Effector T-cells to assist in fighting the pathogen. This type of immunity is more focused and specific antibodies are released for specific infections/pathogens. It lasts up to 5 days or longer depending on the pathogen. It also takes time to mount up and produce a response.
