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.
Radiation is the mechanism of heat transfer by which heat travel in a straight line at the speed of light, allowing heat to travel through vacuums and air spaces.
Radiation in physics is the emission or transmission of energy in the form of waves or particles through space or matter medium. This includes:
- Electromagnetic radiation such as radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays (γ)
- Particle radiation beams such as alpha rays (α), beta rays (β), proton rays, and neutron rays (with static energy non-zero particles)
- Acoustic Radiation such as ultrasound, sound waves, seismic waves (due to physical transmission media)
- Gravitational radiation in the form of gravitational waves, or waves of curvature of space-time
Radiation is often classified as either ionizing or non-ionizing, depending on the energy of the particles it hits.

Transform boundary – this type of fault is found where two tectonic plates are moving alongside and parallel to each other mostly in opposite directions. This type of fault is also responsible for the rift valley and block mountains. No crust is destroyed nor new crust formed.
Convergent boundary – At this point, two tectonic plates are colliding because they are moving in opposite directions at each other. The pressure and stress of the collision force causes the plates to begin crumpling and folding at the boundary forming features such as fold mountains (an example is the Himalayas).
Convergent boundary – At this boundary , the denser of the two colliding tectonic plates (usually the oceanic plate) is subsided by the less dense one (usually the continental plate). The plate being subsided begins to melt as it does down into the mantle and becomes liquid rock. This magma rises through the fissures formed at the boundary and erupts into volcanic islands along the boundary.
<span>1. A neighbor is walking her dog to the park during her lunch break on a beautiful sunny day. explain how her skin is working to protect her from ultraviolet radiation due to intense sun exposure. be sure to discuss the specific structures and substances involved in this protection.
Ultraviolet light is dangerous as it could damage the skin. The skin will react by producing a dark granule called melanin which will absorb the light. Melanin is produced by the melanocyte in the epidermis. This will make the skin looks darker, especially people that frequently exposed to light.
2. mike is beginning his summer football camp today. the temperature high today is 85 degrees with moderate humidity. discuss two ways the skin's structures and functions are working to provide homeostasis and temperature regulation in this football player.
The sweat glands will produce sweat and sent it to the epidermis. This will make the epidermis wet. If the humidity is low, the water in epidermis will be evaporated and taking heat from the skin.
When the temperature is too high, the blood vessel in dermis part of the skin will dilate to make the body lose heat more.
3. this weekend you are going camping with your closest friends and family. thankfully, the layers of your skin will help protect you during this adventure. discuss at least two ways each layer, the epidermis and dermis, may protect you on this excursion.
When camping, you might need to interact with the wild plant directly. The epidermis is made of keratinized squamous cell that could protect the skin from any physical damage like a sharp branch. It also protects from bacteria and other microorganisms.
Wilderness has a fluctuating temperature. The dermis has a fat that will help insulating heat when faced with a cold environment. It also has sweat glands to reduce body heat in the hot environment.</span>
The answer is A. Because you large and small intestines is where everything from nutrients to water get absorbed.
