List the structures in the circulatory system the blood travels through from the vena cava to aorta.

Jobisdone [24]

Explanation:

The major blood vessels that are connected to the heart include the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs, where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart) and the coronary arteries (which supply blood to the heart muscle).

Why do mobile advertisers care about driving physical store traffic?

Rzqust [24]

Mobile advertisers care about driving physical store traffic because vast majority of sales still occur in physical stores. The physical stores have a lot of people making them a ready market. The mobile advertisers therefore become more interested in the physical store traffic.

What is the accumulation of differences between species or populations?

FromTheMoon [43]

Answer: Divergence evolution or divergent selection

Explanation:

The divergent evolution/divergent selection can be defined as the process of accumulation of differences between the related populations lies within the species. This process leads to speciation.

This occurs when the two populations of the same species get separated by a geographic barrier. The separated members of the same species experience different selective pressure that are responsible for adaptation in the new environment.

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

What function does a nueron perform in a human body

BabaBlast [244]

Neurons function to process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord, and peripheral nerves.
