More action is needed to ensure safeguards are in place to protect these areas. Nature reserves and other ways of setting land aside to protect species had been a key strategy in the conservation of biodiversity.
Answer:
combines genes from organisms of different species in a lab
Explanation:
Recombinant DNA technology involves the process of joining the genes (DNA) of different multiple species in order to insert into another organism (host). Recombinant DNA technology has many applications in genetic engineering.
One example of Recombinant DNA is the synthesis of Insulin in bacteria cell where a human insulin gene is first inserted into a plasmid vector, then inserted into a bacterial cell that uses its expression abilities to transcribe and translate the gene into INSULIN protein.
This procedure is usually conducted in a laboratory with the use of certain laboratory equipments.
Answer:
only 30% of total energy will be useful ..
So, Useful energy =
13.5J energy is useful
Answer:
Protein.
Explanation:
In the image above, we see a molecule that is made up of several amino acids. The molecule that is made up of amino acids is protein.
Proteins are the most abundant organic macromolecules in cells, fundamental to cell structure and function. They are found in all cell types and viruses.
They are formed by amino acids linked together and joined by peptide bonds, as shown in the image above.
Of extremely high molecular weight, proteins are composed of carbon, hydrogen, nitrogen and oxygen, practically all of them have sulfur. Elements such as iron, zinc and copper may also be present.
All proteins are made up of a set of 20 amino acids, arranged in varying specific sequences.
The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body. Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.
