Which of the following is a step that occurs within an inflammatory response?
natka813 [3]
Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues.  This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.Inflammatory response takes place in the following steps:1. Tissue damage caused by injury or bacterial infection is detected.2. Vasodilators and chemotactic factors such as  histamine are released.3. As a result, there is increased capillary permeability and blood flow to the area.4. There is migration of phagocytes to the site of infection.5. Phagocytes and specific serum proteins attack and destroy bacteria.<span>6. Inflammation dies down once intruder has been destroyed.</span>

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>

Difference between specialist and generalist species and their niches?? Example of both?? A little help please
igor_vitrenko [27]

A generalist species is able to survive in a wide variety of environmental conditions and can make use of lots of different resources. Generalist species have a big niche. Humans, rabbits, house flies, and raccoons would all fall under the generalist species list.

A specialist species can only thrive is a small variety of environmental conditions and/or only has a limited diet. Specialist species have a small niche. Pandas, koalas, and salamanders would all fall under the specialist species list.
