The structure of the cell membrane allows it to be selectively permeable. What is the name for the larger, brown structure in th
Anika [276]

Explanation:

B) protein channel

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via <em>diffusion,</em> small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

  • Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane.
  • Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

By which process are fossil fuels formed?
Lilit [14]
They are formed by natural processes like anærobic decomposition. They contain energy from ancient photosynthesis. They can literally be around 650 million years old.

Answer the following:
mihalych1998 [28]
A. behavioral isolation is when the plant or animal acts a particular way to attract their counterparts, like mating rituals.

geographic isolation is the natural barrier preventing similar species from interacting. for example, Galapagos Islands are the only home of flightless cormorants because the islands are so far from any other land for them to invade.

Temporal isolation is when two of the same or similar species cannot reproduce as a result of mismatched sexual maturity.

B. the isolation of two frog species by mating call is behavioral isolation.

What is the leaf of a plants function ?
Radda [10]

Answer: photosynthesis

Explanation: leaves are a very important part of the plant. plants are autotrophic in nature. They can synthesize their own food. Leaves have green color pigment in it which is called chlorophyll. This chemical compound chlorophyll uses light energy from the sun and converts water and carbon dioxide into sugars. By this method, plants prepare their own food.
