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>

Which culturing method proivded the clearest results, the semisolid medium tube or the soft agar plate?
sattari [20]
The answer to this question would be soft agar plate.

The semisolid medium tube is mostly used for containing the specimen. It is hard to examine semisolid medium since the bacteria can grow in the upper part, middle part or even the lower part of the medium. In agar plate, the bacteria always growth in the upper part so it is easier to count the bacteria.
But semisolid can give some more information in determining whether the bacteria is anaerobic by looking for bubble inside the medium. Anaerobic bacteria can do fermentation that will produce air.

Bacteria with the ability to break down certain types of plastic are placed with a colony of E. coli bacteria that lack this abi
lana66690 [7]

The answer is; C

Plasmids are conferred through horizontal gene transfer in bacteria.  The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.

Why do some regions specialize in "milk products" like cheese and butter rather than fluid milk? identify some of these importan
kati45 [8]
This happens because these regions are located further away from urban areas and the milk can easily get spoiled before it is delivered to the consumers. Therefore, dairy farms which are away from urban areas, process the milk in order to produce milk products that can last longer. Milk products such as butter or cheese can stay fresh for a longer period of time and they do not get spoiled before reaching the consumers. New Zealand is a place where this practice is quite common since it is located at a great distance from important markets, such as Europe and North America. Milk can be shipped at such a great distance only in the form of processed milk products.
