Leaves are made of a protective tissue that protects against water loss, ground
STALIN [3.7K]

Answer and Explanation:

The epidermis is the outer protective tissue. They have a waxy cuticle that covers the outer walls. The cuticle prevents excessive loss of water and protects the inner cells from mechanical injury and infection. In plants that grow in dry habitats, the cuticle is very thick and waxy to reduce water loss. The leaves are also hairy to reduce water loss. In plants that grow in wet habitat, the cuticle and epidermal cells are transparent to allow light. The cuticle is thin to increase the rate of water loss.

Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.
sergey [27]

Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

Which adaption would prove useful to a group of plants that grow in deserts?
salantis [7]

Answer: The answer is B

Explanation: Because desert plants need to store water for long durations. Plants, for example : the Saguaro Cactus, have a stretchy skin, with a spongy layer inside which enables the plant to distribute and store water for long durations. :) Hope this helps
