Answer:

Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
Extensively drug-resistant
tuberculosis is a form of tuberculosis which is caused by bacteria that are
resistant to some of the most effective anti-TB drugs such as isoniazid and
rifampin. This form of tuberculosis occurs due to an individual’s mismanagement
of multidrug-resistant TB. Treatment for extensively resistant TB would include
medication with at least two drugs to which the TB is susceptible.
I believe the answer is B
Answer:
Explanation: DNA is the information molecule. It stores instructions for making other large molecules, called proteins. and the function of DNA is To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
So to answer your question,
Biotic: plants and other prey (animals)
Abiotic: water, soil,
