Answer:
C
Explanation:
Because between the earth and sun is empty space (vacuum) transfer of heat from the sun to earth can only occur through radiation-  because convection and conduction require a medium. The is the same process that warms your hands when you place them beside a fire. When you put your hands above the fire, they are warmed through convection.
 
        
             
        
        
        
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Answer:
Option 1, 2, 5
Explanation:
Options for the question 
- car a and car b are both moving toward the origin.
- car a and car b are moving in opposite directions.
- car a is moving faster than car b.
- car a and car b started at the same location.
- 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
Option 1, 2, 5

Answer:
Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.
