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

Cows cannot produce their own food. They consume grass in order to get energy for life processes. Cows are _______.

Andrew [12]

Answer:

B. heterotrophs

Explanation:

Heterotrophs gets their food/energy from another organism, thus, cows are heterotrophs.

Suppose that leg length in the Halkan pogo-bouncer, a common insect on the planet Terran02, is determined by five loci, A, B, C,

Sergeu [11.5K]

Answer:

40mm

Explanation:

each AABBCCDDEE = 55

each will contribute 55/5 = 11

thus, AaBBCcDDEe will be 5.5 + 11 + 5.5 +11 + 5.5 = 38.5, approx. 40mm

Thorns and small hairs on plant stems and leaves help to

Mkey [24]

The correct answer is - physically dettering herbivory, protection from frost, and minimizing evaporation.

The plants have developed multiple traits that help them in multiple different circumstances, and some of those traits are the thorns and the hairs on their steams and leaves.

The thorns primarily serve for protection of the plant. They are very sharp and give a painful sting (occasionally poisonous one), so they are a physical protection from the herbivores that would try to eat parts of the plants.

The hairs have multiple functions. They are like a coat that helps the plant to not be affected by frost, help to stop the evaporation, and also partially manage to stop most of the insects that feed on plants.
