Fantom [35]

<u>Answer:</u>

The<u> deductive reasoning</u> is an inquiry process that begins with a theory, prediction, or general principle that is then tested through data collection.

<u>Explanation:</u>

Deductive reasoning or logic is the reasoning mechanism from one or more statements in order to draw a logically definite inference. Deductive reasoning moves in the same direction as conditional reasoning and connects assumptions to judgments.

Both inductive and deductive reasoning aspire to build a reasonable argument. Inductive reasoning thus jumps from specific instances to a generalized conclusion, while deductive reasoning steps from generalized concepts, which are regarded to be accurate to a real and specific assertion.

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.

3. MS-ESS2-5. What usually happens when a cold front and a warm front collide? Tornadoes Rain High Wind all of the above​
Illusion [34]

Answer:

The correct answer is - all of the above.

Explanation:

If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.

It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.
