Atmosphere creates favorable conditions for the creation of food for living organisms via these cycles. </span>
Answer:
Sally's digestive function would be more affected by the consumption of antibiotics due to certain vitamins might not be synthesized and foods might not break down as well.
Explanation:
Options for this question are:
- <em>Certain vitamins might not be synthesized and foods might not break down as well.</em>
- <em>Foods will not be able to be digested at all and will remain in the stomach.</em>
- <em>Sally's digestive function will not change because gut flora do not affect digestion.</em>
- <em>Sally's stomach may become bloated due to an inability to break down lactose.</em>
The gut bacterial flora -also called intestinal microbiota- is linked to multiple metabolic and immunological functions, among others.
One of the functions of gut bacterial flora is to promote the breakdown of food into particles that can be more easily absorbed. In addition, they perform the function of synthesis of some vitamins, such as biotin, vitamins B12 and K, folic acid and pantothenic acid.
<em>The intake of antibiotics can affect the gut bacterial flora, producing in Sally a difficulty to digest food and produce vitamins</em>.

<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
