what effect does binding of epinephrine to a G protein linked receptor have on a cell?
Epinephrine generates the separation of the G protein linked receptor and it activates the G protein to trigger proper cellular signaling.
What is Epinephrine?Epinephrine is a key chemical messenger (i.e. a hormone) that binds to suitable ligands in the cell membrane.
Upon Epinephrine binding, G-protein is activated to produce a molecular cascade and triggers a cell signaling inside the cell.
In conclusion, Epinephrine generates the separation of the G protein linked receptor and it activates the G protein to trigger proper cellular signaling.

Absorption of nutrients
Movement in water
Predator protection
Photosynthesis
The main function of fungus’s hyphae is the Absorption of nutrients by the fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes.
What are the fungal hyphae?The fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes. Chitin makes up the rigid cell wall of hyphae. In pursuit of more food sources, they spread out from a tip and continue to expand.
The substrate is broken down by digestive enzymes secreted by the hyphae, which makes it simpler for the fungus to absorb the nutrients it contains. The fungus has a very wide surface area compared to its volume, which indicates that it is in close contact with its surroundings.

What are the products in this chemical reaction?
A. C3H8 +502
B. 4H₂0 +502
C. 3C0₂ + 4H₂O + energy
D. C3H3 +3CO2 + energy
Answer: it's 3CO2+4H2O+Energy
Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.
The reaction of its complete combustion by the presence of oxygen is:
C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)
As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.

What about Earth allows it to maintain bodies of water?
OA. Weak gravity and high temperatures
OB. Moderate temperatures and strong gravity
C. Strong magnetic fields and lunar tides OD. Comet crashes and mountains
Answer:
Letter C is correct
Explanation:
Earth's moderate temperatures allow water to exist in all three states: solid, liquid, and gas. Its strong gravity keeps the water from escaping into space. Hence option B is correct.
The other options are not correct. Weak gravity would not be able to hold water on Earth, and high temperatures would cause the water to evaporate.
Strong magnetic fields and lunar tides do play a role in shaping Earth's oceans, but they are not the primary factors that allow Earth to maintain bodies of water.
Here are some other factors that help to maintain bodies of water on Earth:
The Earth's atmosphere, which traps heat and prevents the water from freezing.
The Earth's rotation creates the Coriolis force, which helps to distribute the water evenly around the planet.
The Earth's tilt, which causes the seasons, affects the amount of sunlight that reaches different parts of the planet and affects the temperature of the water.
Therefore, option B) Moderate temperatures and strong gravity are correct.
