Answer:
Environmental awareness is an incredibly important part of our lives. In order to protect the sustainability of the planet, everyone needs to commit to becoming more environmentally aware. Environmental degradation is detrimental and is jeopardising the long-term health and security of animals, plants and humans.

When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective.
Answer:
It means one trait does not influence the expression of the other. Example is given in the explanation section.
Explanation:
A trait is the phenotypic characteristics an organism possesses. It is determined and controlled by genes. According to Mendel, an organism receives two forms of every gene called ALLELE. Each allele of a gene encodes a different trait.
Mendel, in his law of independent assortment stated that the inheritance of a trait encoded by the alleles of one gene does not influence the inheritance of another trait encoded by the alleles of another gene. A trait is said to be independent of another if it doesn't influence the expression of the other trait.
An example is the seed colour and seed shape trait in a plant. The seed colour trait is encoded by a certain gene and its expression and inheritance is independent of the seed shape trait encoded by another gene.
Answer:
The correct option is<em> D) Models are not the "real thing" so it will never correctly represent the system in all respects.</em>
Explanation:
Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.
As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.
Answer: Peptide bond
Explanation: A peptide bond is the covalent chemical bond bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme integrated into the growing chain.
In the elongation stage ie when Long chain polypeptides are forming , peptide bonds are formed by linking many amino acids to each other. These peptide bonds of amino acids are relatively unstable, and can break spontaneously in a slow process as can be seen especially in enzymes of living organisms in the making and breaking of bonds.
