Answers
Answer:
I want to say option D: right to review their medical records. Sorry if my answer is wrong
Right to review their medical records is not guaranteed to workers by the Occupational Safety and Health Administration Act. Hence option 4 is correct.
What is health administration?Health administration is defined as the administration of all non-clinical tasks necessary to run a healthcare facility, including daily management, staffing, budgeting, and financial management as well as long-term strategic planning to assure the success of the healthcare provider or system. With an MBA, students can get the knowledge and abilities necessary to succeed as business managers.
All employees are granted three essential rights under the Occupational Health and Safety Act: the right to information about health and safety issues. the right to take part in choices that can influence their health and safety. the ability to decline tasks that would endanger their health, safety, and the welfare of others.
Thus, right to review their medical records is not guaranteed to workers by the Occupational Safety and Health Administration Act. Hence option 4 is correct.

A group of scientists determines that a mitochondrial DNA sequence shared by two species has a constant mutation rate. The sequences of mitochondrial DNA for the two species are shown below. Species A: GACTGGGCATTA Species B: GACCGGACATTA Based on this information, which of the following best explains the difference in the DNA sequence between the two species? Species A and B probably share the most recent ancestor because they only differ by three mutations. Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. Species A and B probably have distinct ancestors because they have many differences in mutations. Species A and B are closely related because they differ by five mutations in their DNA sequence.
Answers
Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. It is likely due to sequence homo-logy.
Whta are mutations?A mutation is any alteration in the nucleotide (DNA) sequence of the genome of a particular organism.
The linear order of nucleotides and their differences (mutations) can be used to infer homo-logy between two species.
In this case, there are only two different nucleotides in these sequences, thereby sequence homo-logy indicates a likely common origin.

The coefficient of viscosity of blood is directly proportional to the frequency of interactions of erythrocytes with the vessel walls. As blood enters small vessels, many erythrocytes tend to flow in the center of the vessel. Given this information, which graphic best describes the effect of vessel diameter on the coefficient of viscosity?.
Answers
The coefficient viscosity is the resistance for blood to flow. There is a direct relationship between vessels diametre and viscosity. In the attached files it is the graph that best describes this relationship.
What is blood viscosity?
Viscosity is the property of fluids to resist the tangential displacement of molecule layers.
Blood viscosity refers to the resistance for blood to flow. Blood viscosity depends on the blood density and the vessel diameter.
Viscosity increases when the number of blood cells increases and when more cells get in contact with vessels walls.The more viscose is in the blood, the greater resistance there is to move it, and the more blood pressure it requires to flow through vessels.
Viscosity decreases when blood velocity increases.According to this framework and to the problem statement, we could assume that
smaller vessels ⇒ faster flow ⇒ less wall resistance → less vistositybigger vessels ⇒ slower flow ⇒ more wall resistance → more viscosity
In smaller vessels, blood flow is greater and more cells move in the center, leading to fewer cells interacting with walls. There is higher pressure and less resistance for blood to flow.
In bigger vessels, blood flow is slower, and more cells are interacting with each other and with the vessel walls. There is lower pressure and more resistance for blood to flow.
Since the coefficient of viscosity is directly proportional to the frequency of interactions of erythrocytes with the vessel walls, we can assume that blood flowing through bigger vessels express a higher coefficient of viscosity than blood flowing through smaller vessels.
In the attached files you will find an image representing the relationship between the coefficient of viscosity and vessel diameter.
You should compare this image with your images and choose the correct one.

Cell division is the process by which a parent cell divides into two or more daughter cells.
Cell division usually occurs as part of a larger cell cycle.
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
Meiosis takes place in the reproductive organs. It results in the formation of gametes with half the normal chromosome number.
