<span>The modern synthesis theory states that evolution occurs through changes in the gene pool of population. The modern synthesis theory is often described as Neo-Darwinian theory because it is a fusion of Mendelian genetics and Darwinian evolution. It states that all evolutionary theory can be explained by genetics. </span>

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

Scientists studied reproduction in the New Zealand mud snail to answer the question, “Are there benefits to reproducing sexually
Elena-2011 [213]

Answer:

Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.

Explanation:

The main advantage of sexual reproduction is that it increases the genetic variation in the species by creating new combinations of alleles.

However, asexual reproduction produces more offspring, as it is usually a quicker method of reproduction. It also does not require the organisms to socialise to mate.

Sexual reproduction does not reduce the rate of mutation, which is influenced by environmental factors as well as the genome itself.
