Answer: The receptor site is the location that a drug binds to, altering the function of a biomolecule.
Explanation:
The drug receptors site, are the sites where the sites where the drug molecules bind. Basically, a low number of receptors exists and the extent to which the molecules occupy their sites differ with the concentration of drug. The receptor site changes the conformation and function of the binding molecule of the drug.
Answer:
C) lumbar vertebrae; short, flat spinous processes
Explanation:
The Lumbar Vertebrae are bigger and stronger than vertebral bodies in certain positions.
The vertebral bodies and disks bares majority of the body weight of the body. The lamina, facets and spinous process are basic components of the posterior materials that assist in guiding the movement of the vertebrae and as a coverage or protective shelter for the spinal cord.
The spinous process are SHORT and STURDY (FLAT) in the Lumbar Vertebrae. Hence, this explain why it is often referred to as "Hatchet-Shaped".
The attached image as red dots meant to point to the spinous process in the Lumbar Vertebrae.
Answer:
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Explanation:
Oceans act as conveyor belts of cold and warm water, <span>sending heat toward the polar regions and helping tropical areas cool off.
helps distribute heat around the globe

During cell differentiation, new proteins are expressed
During cell differentiation, some genes are silenced while some or expressed. Different cells differentiate differently depending on the type of cell is going to become. This is why even though all the cells in a multcellular organism have the same DNA, they become different organ systems that look different.
Explanation:
Different differentiated cells produce different proteins because they express different genes. For example Cells of the epidermis of the skin express the genes for producing keratin (the pigment molecule) while those in the dermis do not express this protein because this gene is silenced in dermis cells. In addition, in dark-skinned people, these genes are more expressed that in people with light skin.
