A microscope is used to look at a cell form a tree leaf. Which structure would be seen that would not be found in a cell from a
aivan3 [116]

The animal cell and the plant cell have some organelles in common but there are some organelles that belong to only one of the cell. In the question given here, mitochondria, cillia and ribosomes are found in both plant and animal cells. The cell wall is found only in the plant cell. So, the correct option is B

Hope that help!

In two or more complete sentences describe a long term effect of water erosion on humans, and discuss how this might be reduced
Ghella [55]

Answer:

Water erosion refers to the removal of the top most or surface layer of soil by the flow of water.  The long term effect of water erosion can be because of drastic rain fall and may be because of flood. These two reasons can adversely effect the human life. The water erosion is responsible for the removal of fertile layer of soil, therefore, the region will not be appropriate to grow vegetation. The long term effect may result in stagnation of water, therefore, long time is required so that the region gets dried. The long term accumulation of water over an agricultural field can spoil the crop production.

Prevention that can be taken to reduce long term effect of water erosion:

1. Plantation of long root bearing trees over flood prone regions and around the agricultural field: This will allow the trees to tightly hold up soil and prevent it's erosion.

2. Add rocks over the soil: In an agricultural field or flood prone area, the rocks will act as barrier for the movement of run off water, hence, will prevent water erosion. It will increase the absorption of water by soil.

3. Building of walls: This will also act as a barrier in a flood prone region and will prevent the water being added up to the agricultural land.

4.Remove soil compaction: If the soil compaction of the effected region is removed, the water retention property of the soil can be improved. Machines, animals and humans can be used for this purpose to remove the compaction of upper layer of soil.

Explanation: hope this helps.

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.
