Viktor [21]

Answer:

cAMP dependent pathway is important for processing of life.

Explanation:

cAMP pathway is also called as adenynyl cyclase pathway.

This mechanism requires different steps like-

  1. G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
  2. Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change  in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
  3. The Gα  stimulate G protein complex to exchange GDP for GTP and then the complex is released.
  4. Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
  5. Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
  6. Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.

A hypothesis is a ___.
Aloiza [94]

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. <u>It is a specific, testable prediction about what you expect to happen in a study.</u>

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that <em>The hypothesis</em><u> is a simple statement that defines what you think the outcome of your experiment will be.</u>

<em>Hope</em><em> </em><em>this helps</em><em>.</em><em>.</em><em> </em>

<em>Good</em><em> </em><em>Luck</em><em>!</em>

Answer:

Sorry only paragraph I'm on phone.

Explanation:

Fruits and vegetables have changed a lot since the onset of agriculture 10,000 years ago, as generation after generation of farmers artificially bred crops to select for more desirable traits like size and taste.
