A dog pants in the heat to control its body temperature. Panting is a mechanism of_______ that dogs use for_______ .
Maru [420]

B. homeostasis B. regulation

Panting is a phenomena for maintenance of homeostasis in the body. In panting water from the inner moist lining of the oral cavity and pharynx get evaporated. This method of heat loss during hot and humid conditions is applied by dogs and other mammals to keep them cool. It is a kind of heat regulation process. Dogs keep there mouth open so that excess heat can liberate from their body.

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.

loris [4]

Answer:

10. View the slides on the PowerPoint to match each of the cell structures with the correct letter labels for

each of the following cells.

Elodea Cell Cell wall _B____ Chloroplast _A___ Area of vacuole _C__ Onion Cell Cell wall _B__ Nucleus __A_ Mitochondria _C__ Cheek Epithelial Cell Cell membrane _B__ Nucleus __A_ BacteriA Bacterial Cells. View the bacterial cells on the PowerPoint and identify which cell (A, B, or C) is: Coccus ________B____ Bacillus ______A______ Spirillum ______C______ Protista Amoeba can move via the extension of finger-like projections called pseudopodia

Explanation:

Amoeba can move via the extension of finger-like projections called pseudopodia, what prevents plant cells from moving in the same fashion?

Ans: The plants that prevent the information of pseudopodia have rigid cell walls. which is unlike to amoeba.  

How does the euglena compare to both plant and animal cells (i.e. - explain what structure(s) might make it similar to plants and what structures might make it similar to animals).

Ans: Euglena are similar to plants because they both have chloroplast and are similar to animals because  neither has a cell wall.
