Answer:
The correct answer would be C) respiratory system.
Respiratory system is made up of set of organs which help in taking in oxygen and expelling out carbon dioxide from the body.
In humans, it is composed of nose, pharynx, larynx, trachea, bronchi, pair of lungs, and diaphragm.
Alveoli (in lungs) are the site of gaseous exchange where oxygen is exchange with carbon dioxide.
Carbon dioxide is the toxic waste product of cellular respiration. Circulatory system helps in transporting CO₂ from cells to the alveolar site where it is exchanged with oxygen and excreted out as a part of exhaled air.
Answer: C
Explanation: got it right
B) Mutations can be positive and produce organisms with improved traits.
C) Mutations can be fatal to the organism that has a mutation, if the mutation is in a critical gene.
D) Mutations can be silent, and not affect the organism that has them, if the mutation is in a non-critical area.
Answer: The correct answer is- A) Mutations must be present in parents and then passed to offspring.
Mutation can be described as the permanent change in the genetic material ( DNA) of an organism. It can be beneficial or harmful to the life form. Mutations can be heritable ( that is passed from one generation to the next) or non inheritable ( not passed from parents to offsprings).
A silent mutation ( change in the nucleotide sequence without any change in the amino acid sequence) that does not show any observable effects in the phenotype of the organism.
Thus, only option A) is not true about mutation.
All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.
Thus, An organism's observable traits, or phenotype, may or may not change as a result of a mutation. Evolution, cancer, and the maturation of the immune system, including junctional variety, are among the normal and malignant biological processes in which mutations play a role.
All genetic variety originates from mutation, which also provides the basis for the action of evolutionary forces like natural selection.
Sequence changes can take many distinct forms as a result of mutation. Gene mutations can have no effect, change the gene's product, or stop the gene from working fully or correctly. Non-genic areas are likewise susceptible to mutation.
Thus, All the statements are true about mutations except Mutations must be present in parents and then passed to offspring.

Answer:
c
Explanation:
Answer:
Proteins
Explanation:
A reversible reaction is a chemical reaction where the reactants form products and products react together with reactants to give the reactants back. When they yield the same amount, Reversible reactions will reach a chemical equilibrium in which the concentrations of reactants and products will no longer change.
Explanation:
A reversible reaction is a reaction where the reactants form results, which react collectively to give the reactants back. A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from the reversible method in thermodynamics. Reversible reactions will relinquish an equilibrium point where the concentrations of the reactants and products will no longer break
