Answer:
<em>Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.</em>
Explanation:
Dichotomous keys are used in the identification and classification of taxa.
Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.
Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.
Answer:
Metabolism is a set of chemical reactions that they release energy for cellular processes.
Explanation:
Metabolic processes in cells are:
* Metabolism-the whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
* Cellular respiration-a process in which organic matter is oxidized, whereby carbon dioxide, water, and energy in the form of ATP molecules are formed as end products of this oxidation.
Answer:
The answers are a) Cancer cells treated with the chemical have a lower survival rate than cells that are not treated and d) This chemical will be useful for treating all types of cancer.
Explanation:
Since the research finds that cancer cells have a lower survival rate when exposed to a particular species of fungus. In addition to this new chemical compound could be implemented as a cancer drug.
Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.
The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.
Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

Answer:
Enzymes are proteins that act as biological catalysts. Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
