Answer: diffusion

Explanation:

Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.

This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .

Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.

It is also dependent on the size of the molecule

What are the biggest advantages of natural gas as a fuel source?
GaryK [48]

Due to its cleaner combustion, natural gas is the most environmentally safe fossil fuel. Natural gas doesn't have as many toxic combustion byproducts as other fossil fuels.

  • Natural gas is adaptable. Starting and stopping a gas-fired power plant is substantially faster than one that burns coal.
  • Due to its flexibility, it complements renewable energy sources like solar and wind, which are only usable when the sun is out and the wind is blowing.
  • When burned to produce power, natural gas is the cleanest-burning hydrocarbon, releasing about half as much carbon dioxide (CO2) and only one-tenth as much air pollutants as coal.
  • By switching to natural gas from coal, there is a significant opportunity to cut CO2 emissions and air pollution in the near future.
  • Because Natural gas is now so widely accessible through LNG, it can assist nations in coping with short-term supply interruptions.

stich3 [128]

The right answer is Nutrients and water.

All unicellular organisms such as bacteria and fungi need water, a source of energy, a source of carbon, a source of nitrogen and mineral elements. These basic needs are sufficient to allow the nutrition of bacteria qualified as prototrophs. Some bacteria called auxotrophs require, in addition to basic needs, the presence of growth factors.

The correct option is "D", "<span>The density of seawater".
As you are measuring the</span><span> amount of mass in a volume of water and if we look at the definition of density, it is the mass per unit volume.
D = m/v
where m is the mass of an object and v is the volume.
Thus, d is the correct option.</span>

What determines the similarities in anatomical features among organisms?
gogolik [260]
The most common example that determines the similarities in anatomical features among organisms is the bone structure, commonly used in comparative anatomy. For example, the forelimbs or appendages of bats, humans, cats and whales have the same basic parts but they differ in function. Fins of whales and wings of bats have the same skeletal parts, but fin is used for swimming while wing is for flight. These structures could be termed as homologous, analogous, or homoplastic. However, recent developments have been made than just basing to the skeleton - the main reason why we have comparative genomics today.
