Answer: Missense mutation

Explanation:

Missense mutation is a type of point mutation where a single nucleotide is changed to cause substitution of a different amino acid. This in turns render the resulting protein non-functional.

In the case of sickle-cell disease, the sixth amino acid in the gene sequence, glutamate (GAG) is substituted with valine (GUA), due to Adenine nucleotide changed to Uracil nucleotide. Thus, missense mutation has occurred

Which of these ideas correctly states a relationship between the practice of conserving energy and the effect that it has on peo

Bess [88]

The idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes (option B).

<h3>How is energy conserved?</h3>

To conserve means to use judiciously or wisely, therefore, energy conservation refers to the effort made to reduce the consumption of energy by using less of an energy service.

The conservation of energy helps to reduce workload on mechanical devices such as air conditioner, cooker etc.

Therefore, the idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes.

A microbiologist plated a bacterium on a specific medium. After incubation, she noted that the previously yellow medium was now

alexdok [17]

Answer:

A differential medium

Explanation:

Bacteria require nutrients for growth, and in order to culture (grow) them and study their characteristics, different types of media are used.

A selective media is used to grow a particular group of organism while suppressing another. So a selective media usually has an inhibitory agent, which will inhibit the growth of the undesired group. An antibiotic can be added to a medium to make it selective.

A general purpose medium as the name implies can be used to grow any group of bacteria. It has no inhibitory agent and indicator that differentiates between organisms. An example of general purpose media is nutrient agar .

A non-synthetic media is made from natural ingredients.

A differential media differentiates between groups of organisms. Example of differential media is MacConkey agar and Mannitol Salt agar. On MacConkey agar, lactose fermenting bacteria turn pink while non-lactose fermenting bacteria are colorless.

On Mannitol Salt agar, mannitol fermenting bacteria turn yellow while non-mannitol fermenting bacteria are colorless. Mannitol Salt agar is also a selective medium. It has a high salt concentration which inhibits certain organisms.
