Answer:
1) Movement to area of lower concentration: facilitated diffusion . It consists in the diffusion of a substance through a membrane in favor of its concentration gradient, that is to say that there is movement from an area of greater concentration to another of less concentration.
2) Movement assisted by proteins: both. In the facilitated diffusion the molecules must pass through membrane proteins. In active transport, the proteins involved are called pumps that normally use chemical energy.
3) Requires energy active transport: active transport makes use of energy for the movement of molecules because the movement is against a concentration gradient.
4) Sodium ion transport out of the cell: It is a type of active transport because it requires energy to allow movement against its concentration gradient, the ATP supplies the energy.
5) Glucose transport into cell: It is a type of diffusion facilitated through membrane proteins.
6) Movement across a membrane: both
75km/hr due east
Explanation:
The velocity of the train will be 75km/hr due east.
- Velocity is given as the rate of change of displacement with time.
Velocity = 
- Velocity is a vector quantity that has both magnitude and directions.
- It is different from speed because it has the directional attribute.
- From the given data, we know that the train is moving at 75km per hour. This is the speed of the train.
- If we incorporate the direction then we have its velocity.

The products of photosynthesis are sugar molecules (glucose) and oxygen. <span>Photosynthesis is the process in which light energy is converted to chemical energy. In this process, water and carbon dioxide combined with light energy produce glucose molecules (or other sugars) and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy (glucose contains chemical energy) and fixed organic carbon atom. The energy of glucose is used in the process called cellular respiration where adenosine triphosphate-ATP is generated.</span>
