The situation that is most likely to result in a mutation that is passed on to an offspring is exposure to a chemical that affects cell formation. The correct option is C.
What is mutation?A mutation is changing or modification in the nucleic acid or DNA sequence of a person. This is a natural process that occurs due to mutagens.
Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. An example is an aneuploidy is a condition of the presence of more or less number of chromosomes than normal. For example, there are 45 or 47 chromosomes are present.
There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.
Therefore, the correct option is C. exposure to a chemical that modifies cell formation.

Some insect species are resistant to pesticides. Which statement BEST explains this phenomenon? Natural selection resulted in an unfavorable variation for the insects. Because their survival depended on it, the insects developed variations that made them resistant to poisons. Random variation in the population led to a population with a favorable adaptation. Some of the insects became instantly immune when the poisons were introduced into their environment
Answers
Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-de novo mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).

What type of cell transport is shown in the figure below?
Facilitated diffusion
Active transport
Endocytosis
Simple diffusion
Answers
The type of cell transport which is shown in the figure in question is Facilitated diffusion. The diffusion in this transport is carried out with the help of a protein such as carrier protein or channel protein. Thus, the correct option is A.
What is Facilitated diffusion?
Facilitated diffusion is a type of diffusion where the movement of solute and solvent particles takes place from the region of higher concentration to the region of lower concentration.
The cell membrane is selectively permeable in nature as it allows the movement of selected substances through it. The molecules which are impermeable such as large, charged polar molecules cannot cross the membrane on their own and hence requires a protein which facilitates their movement. Thus, for this purpose the carrier and channel proteins which are present in the membrane facilitate this diffusion of substances.
Therefore, the correct option is A.
