Answer:

Positive Geotropism means growth of the plants towards the Gravitational force. e.g.It means When a plant's root grows towards Gravitational force . It is positive geotropism. Negative Geotropism means growth of the plant against the Gravitational force. e.g. When a plant's steam grows towards sunlight.

A gas that exerts a pressure of 537 torr in a container with a volume of 5.30 L will exert a pressure of 255 torr when transferr
ArbitrLikvidat [17]

Answer:- The gas needs to be transferred to a container with a volume of 11.2 L.

Solution:- From Boyle's law. "At constant temperature, Volume is inversely proportional to the pressure."

It means, the volume is decreased if the pressure is increased and vice versa.

Here, the Pressure is decreasing from 537 torr to 255 torr. So, the volume must increase and calculated by using the equation:

P_1V_1=P_2V_2

Where, P_1 is initial pressure and P_2 is final pressure. Similarly, V_1 is initial volume and V_2 is final volume.

Let's plug in the values in the equation:

(537 torr)(5.30 L) = (255 torr)(V_2)

V_2=(\frac{537 torr*5.30 L}{255 torr})

V_2 = 11.2 L

So, the new volume of the container needs to be 11.2 L.

Compare the shape of a chemical signalling molecule and a receptor.
Andru [333]

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.
