Summary Introduction

To describe:

The energy transformations that occur when a person climbs to the top of a stairway.

Introduction:

The capacity to cause a change is known as energy. The change in the form of the energy is known as transformation of the energy. These forms are used to perform work, for example, movement of an object against an opposing force such as lifting a heavy weight against the gravitational force.

Expert Solution & Answer

Explanation of Solution

When an individual is climbing a stairway the stored chemical energy from the food is converted into kinetic energy. Kinetic energy is the energy of motion that takes the form of “muscle movement”. After reaching at the top of stairway some of stored energy is transformed into “potential energy” because of the raised location.

Potential energy is stored kinetic energy. Some amount of energy is converted into heat during the transformation of energy. These are some of the energy transformations occurring when an individual climbs to the top of a stairway.

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences  A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?
Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
