Which resource takes the longest amount of time to renew?
mash [69]

Answer is c. Natural gas.

Natural gas is a fossil fuel in liquid form that can be used as an energy source. It is found in subterranean reservoirs, often near oil deposits. It is non-renewable energy source. It takes very long time to renew. Natural gas is less pollutant as compared to coal and petroleum because when it's burned, it releases 25 % fewer greenhouse gases and pollutants. hydroelectric power, solar power and nuclear energy are renewable sources.

A mutation in a G-protein prevents the alpha-subunit from dissociating from the beta/gamma-subunit. What effect will this have o
Ymorist [56]

Answer:

the pathway will be under-expressed.

  • the alpha subunit helps to bind with either GDP or GTP. when the α subunit is bound with GDP, it will be bound to β and γ subunits and thus forms an inactive state for G-protein.
  • when the alpha subunit binds with the GTP, it becomes activated and dissociates β and γ subunits.

if G-protein Coupled Receptor is unable from dissociating β and γ subunits, then the pathway will go under expression.  

The chemical qualities of the alpha subunit allow it to bind easily to one of two guanine subunits, GDP or GTP. The protein thus has two functional formations. When GDP is bound to the alpha subunit, the alpha subunit remains bound to the beta-gamma subunit to form an inactive trimeric protein.

G-proteins, cAMP, and Ion Channel Opening. The alpha subunit activates adenylate cyclase, in purple, and loses GTP. Adenylate cyclase converts ATP to cyclic AMP, which then activates Protein Kinase, shown in blue. Protein Kinase phosphorylates an ion channel, letting sodium ions rush into the cell.

As a result of the ligand binding to its site on the G-protein-linked receptor, A) the G-protein changes conformation and GTP replaces the GDP on the alpha subunit. ... Inactivation of the alpha subunit occurs when its own phosphorylase activity removes a phosphate from the GTP.

How much of the suns engry do mushrooms take!!!!!

To understand food chains and food webs, we must start with where the energy begins. Sunlight is energy, and plants use this energy to turn water and carbon dioxide into plant food. This process is called “photosynthesis”. Plants also need minerals and nutrients. They get these from the soil when their roots take up water. While this might not sound like the kind of food you would want to eat, this plant food allows plants to grow, flower, and produceproduce things like acorns, potatoes, carrots, apples, pecans, and many other kinds of fruits.

Because plants make so much energy, they are called “producers”. Their ability to use sunlight to make food makes them a very important source of energy for other living things. Think about all the animals that eat plants. Wow, it's mind-boggling! Now, think about all the places that plants grow. From the oceans to the deserts to the mountaintops, plants can be found nearly everywhere basking in the sunlight and making their own food. And wherever plants grow, animals that depend upon them are sure to be found.
