Roger is studying how energy from the Sun changes to chemical energy in plants and to mechanical energy in animals. He is studying thermodynamics.
Answer:
C
Explanation:
This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a lower water potential, but higher solute potential.
Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.
Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.
The answer is <span>5.2 × 10-2 newtons.
To calculate this, we will use Coulomb's Law:

Answer:
Plants can be used to make materials.
Explanation:
Plants are important living organisms and they can be used in many ways. Some plants can be used as foods, some plants are used as raw materials for making medicines and other herbal products. Plants, such as cotton are used to make clothing materials and dead and decaying plants serves as fertilizer that add nutrients to the soil. Some other examples of a beneficial application of plants in human society would be that plants can be used for food. With that, they provide a very important source of nutrients for humans.
