5100.0 has 5 but a 5.100 x 10 cubed(3) has only 4
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
Answer:
Monera
Explanation:
According to Whittaker's system of classification bacteria is not as kingdom so bacteria represent or belongs to Monera that's why Monera is not kingdom
Cell signalling is a process by which cells communicate with each other and transfer messages.
<h3>What is a receptor?</h3>
A molecule inside or on the surface of a cell binds to a specific substance and causes a specific effect in the cell.
Cell signalling is a process by which cells communicate with each other and transfer messages. When a signal molecule binds to a receptor protein, changes occur in the receptor proteins. Two changes are listed below:
1. The receptor protein undergoes conformational changes and acts as an enzyme.
2. The receptor protein that makes a second messenger molecule that leads the reaction further to other cells or molecules.
