Answer:
True
Explanation:
Desertification can be defined as the process whereby a previously fertile land is degraded permanently and thereby becomes unproductive.
Desertification can be caused by human effects such as overgrazing. It can also be caused by changes in climate.
One of the ways to prevent desertification is by protecting land and soil from erosion by incorporating land and water management systems.
Answer:
Recycling reduces the need for extracting (mining, quarrying and logging), refining and processing raw materials all of which create substantial air and water pollution. As recycling saves energy it also reduces greenhouse gas emissions, which helps to tackle climate change.
Explanation:
Recycling is very important as waste has a huge negative impact on the natural environment. Harmful chemicals and greenhouse gasses are released from rubbish in landfill sites. Recycling helps to reduce the pollution caused by waste. ... Recycling reduces the need for raw materials so that the rainforests can be preserved.
A vapor layer forms between them, so the two don't really collide.
When the right ventricle contracts it pushes the blood into the pulmonary trunk which sends the blood to the lungs for gaseous exchange. If you need more details let me know :)
Answer: c). No; while the noncovalent bonds determine the shape of a protein, the peptide bonds are required to hold the amino acids together.
Explanation: Peptide bonds is a type of bond that covalently joins two or more amino acid molecules through a substituted amide linkage. Peptide bond is formed by the removal of the elements of water from the alpha carboxyl group of one amino acid and the alpha-amino group of another amino acid. When two amino acids molecules are joined by peptide bond, the resulting molecule is called a dipeptide, when three amino acids molecules are linked by two peptide bonds, a tripeptide is formed. When a few amino acids are joined by peptide bonds, the structure is called an oligopeptide, when many amino acids are joined, the product is called a polypeptide.
Since the enzyme breaks the peptide bonds, it means that the protein has been broken down into its constituent amino acid, therefore the protein has lost its primary structure and therefore will no longer retain its shape.
