The right answer is C.

Incomplete dominance is when hybrids of the F1 generation have an intermediate phenotype (between the two phenotypes). That is, in the case of familial hypercholesterolemia, if the subject is heterozygous it will have 50% functional receptors compared to a healthy homozygous subject.

Do any cells in the population express Glut4 on their surface? Is this expression dependent on the presence of insulin receptor?
IceJOKER [234]

Answer:

Glut4 is only expressed in insulin-sensitive skeletal an heart muscles and fat tissues.  

Explanation:

Glucose transporters represent a group of integral membrane proteins that allow the transport of glucose molecules across the plasma membrane by the mechanism of facilitated diffusion (i.e., without direct coupling to ATP hydrolysis). In humans, the Glucose Transporter type 4 (GLUT-4) is a glucose transporter encoded by the SLC2A4 gene. This protein plays a critical role in regulating glucose homeostasis by enabling to increase the transport of glucose in response to elevated blood insulin levels in adipocytes, skeletal and cardiac muscle tissues.

We also know that the astronaut’s weight on Earth is 156.6 pounds. Which equation models the situation? no links pls they didn't
Klio2033 [76]

Given what we know, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth.

<h3>What is Mass and the force of gravity?</h3>
  • Mass is the amount of matter in an object or body.
  • What we refer to as weight, is really the force being applied by an object together with the force of gravity.
  • Gravity is an invisible force applied by the earth on all objects.
  • Together will mass, these forces create what we know as weight.

Therefore, we can confirm that the equation to model the situation can be created by multiplying the mass of the astronaut by the force of gravity on earth, which would be 7.2 kg of mass multiplied by 9.807 m/s² which will result in a "weight" of 156.6 pounds or 71 kg.
