a) kidneys eliminate bicarbonate ions.
B) kidneys retain bicarbonate ions.
c) kidneys retain hydrogen ions.
d) kidneys eliminate carbon dioxide.
Answer:
B) kidneys retain bicarbonate ions
Explanation:
Respiratory acidosis involves the inability of the lungs to remove the Carbon dioxide in the body which result in the blood being acidic.
Jane was said to suffer a chest injury that resulted in impaired breathing and respiratory acidosis. Her body will compensate for this imbalance through the kidneys having the ability to retain bicarbonate ions. This helps to reduce the acidity as the ions are alkaline in nature.

Describe epithelial tissues function as an external and internal barrier
Answer:
Epithelial tissue covers body surfaces that are exposed to the environment and also secretes internal regulatory molecules
Explanation:
The epithelium is one of the four main classes of animal tissues (i.e., epithelial, muscle, connective and nervous tissues). The epithelial tissue covers both external and internal body surfaces such as, for example, the skin and the digestive tract, respectively. In the skin, this tissue is a protective layer that prevents water loss and damage by external environmental factors or by mechanical friction. Moreover, in the digestive tract, epithelial tissue plays critical roles for the absorption of nutrients, as well as during regulation and excretion of hormones.
A physician is often able to detect homeostatic imbalances in the body by observing changes in the skin color.

Your friend does not believe in the theory of evolution—specifically because he does not believe that life originated from organic molecules that came together in a primordial soup. As someone who has studied the theory of evolution, how might you respond to his objections
Answer:
Answered below
Explanation:
In the 1920s, Russian Chemist A.I Oparan and English geneticist Haldane, first conceived and developed independently, the theory of Primordial soup. The primordial soup theory suggests that life began in a pond or ocean as a result of the combination of the right amounts of chemicals from the atmosphere and some form of energy, under the right conditions, which resulted in the production of amino acids, the building blocks of proteins from which life evolved. This is suggested to have happened 3 to 4 billion years ago.
This theory was tested by Chemist Stanley Miller and Physicist Harold Urey, in 1950. They mixed gases thought to be present in the primitive earth and electrically sparked the mixture, which resulted in the formation of amino acids.
which of the following best describes the role of an enzyme in living organisms
Answer:
They cause DNA to replicate. They denature each other. They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
The statement that best describes the role of an enzyme in living organisms is enzymes always break down substrates into monomers during a reaction. The correct option is c.
What are enzymes?
Enzymes are proteins that increase the rate of the reaction. In the human body, enzymes are used to break down food molecules. Enzyme inhibitors are biological or chemical substances that bind to an enzyme's active site and prevent the enzyme from performing its activity.
The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. This in turn dictates the enzyme's three-dimensional structure, including the active site's shape.
Therefore, the correct option is c, Enzymes always break down substrates into monomers during a reaction.

Some scholars have viewed RNA as the original site of information storage in the primitive cell. One advantage of this view is that RNA can both store _____ and can act catalytically like a(n) _____.
Answer:
1. Genetic information
2. Protein
Explanation:
RNA world hypothesis was proposed by certain scientists due to their view of RNA being the original site of information storage in the primitive cell. This hypothesis was based on the self-replicating and catalytic abilities of the RNA molecule.
RNA was believed to be the main genetic material, with which life started with because of it's ability to store genetic information like DNA and catalyze chemical reactions like proteins. This is the major advantage of the RNA view as the original site of genetic information storage.
However, the DNA (genetic information storage) and protein (catalytic function) has recently taken over both roles from the RNA.
The number of possible chromosomal orientations during metaphase I is equal to the number of chromosome pairs raised to the 2nd power.
A. True
B. False
Answer:
A
Explanation:
The statement is entirely true.
During metaphase 1 of meiosis, each tetrad - a chromosome consisting of 4 chromatids - formed in prophase has 2 possible orientations. Hence, the total number of possible chromosomal orientations would be 2 raised to the power of the number of chromosome pairs present in the cell.
For example, humans have 23 pairs of chromosomes in each of their cells, hence, the total number of possible chromosomal orientations would be [tex]2^{23}[/tex] which is equal to 8,388,608 possible orientations.
The correct option is A.
