Water harvesting, the collection of rainfall and run off for future use, has been practiced for thousands of years; but in some
lina2011 [118]

Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.

Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;

Reduces Water Shortages

In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.

Replenishes Groundwater

Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.

Reduces soil erosion

Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.

position vs time for two cars which statements best describe the motion of car a and car b check all that apply
jekas [21]

Answer:

Option 1, 2, 5

Explanation:

Options for the question

  1. car a and car b are both moving toward the origin.
  2. car a and car b are moving in opposite directions.
  3. car a is moving faster than car b.
  4. car a and car b started at the same location.
  5. car a and car b pass each other at the crossover  point on the graph.  time (s)

Solution -

The motion of any object is represented by  position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis.

The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.

Hence, the following statements are correct

Blababa [14]

Answer:

a. Uninucleate, nonstriated

Explanation:

Smooth muscle tissue is composed of smooth muscle cells that are spindle-shaped with a single nucleus. Smooth muscles line the walls of hollow organs such as urinary bladder, uterus, stomach, intestines but also arteries and veins and the tracts of the respiratory, and reproductive systems. Smooth muscles are under involuntary control, meaning that their contraction is unconscious.
