tatyana61 [14]

The Earth core has two layers: the outer core, and the inner core. Moreover, the magnetic field protects Earth from solar weather.

The Earth's magnetic field is an invisible layer that protects life from the majority of the solar wind blast.

The magnetic field covers us from charged solar particles that crash into it and then flow around it.

Moreover, the Earth core has two layers: the outer core and the inner core, which are separated by a boundary known as the Bullen discontinuity.

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

How is harvesting food crops similar to, and different from, mining?
Tresset [83]

Answer:

Both extract from the soil while difference in their extraction method.

Explanation:

Harvesting food crops similar to mining because both are gained from the soil whereas it is also different from mining due to their method of extraction. Seeds are grown again and again in the soil and other agronomic activities has to be done to gain good yield of the crops while on the other hand, in mining precious metals is to be extracted that is already present in the soil.

humans enjoy eating largemouth bass what would happen if the fishing industry fished every largemouth bass out of the ecosystem
Kruka [31]

Then they would go extinct

we would not be able to eat them anymore

and the food chain will get messed up because some animals eat the large mouth bass and now they cant, and also the animals that the large mouth bass eats will overpopulate because the large mouth bass isn't there to eat them
