Answer:
The result of loss of topsoil are loss in fertility of soil, loss of water, crop production and hardened soil surface. Therefore, the correct answer to the above question is option A, B, C and D.
Explanation:
When there is a loss of top layer of soil from the earth by any means, natural or artificial, it is known as soil erosion. The soil from one place gets detached and is transported to another area. Planting more and more trees is the one of the way to stop soil erosion as the roots of the plants hold the soil.
When the soil from area is removed there is a loss of production in crop due to various reasons. The most fertile part of the soil occurs in the uppermost part. Therefore, its removal has negative impact.
Answer:
The history of GIS all started in 1854. Cholera hit the city of London, England. British physician John Snow began mapping outbreak locations, roads, property boundaries, and water lines.
John Snow’s Cholera map was a major event connecting geography and public health safety. Not only was this the beginning of spatial analysis, but it also marked the start of a whole field of study: Epidemiology – the study of the spread of disease.
To this date, John Snow is known as the father of epidemiology. The work of John Snow demonstrated that GIS is a problem-solving tool. He put geographic layers on a paper map and made a life-saving discovery.

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.
It's the <span>chloroplast.
