False the goal was to cover the smear if it evaporates the smear is uncovered meaning the goal wasn’t meant. It could also be true though because you could just apply more dye to cover it up. So it might be true
Adaptation is a response to the environment but long term.
For example:
<span>A wolf has a fur coat as an adaptation to the cold weather, but birds migrating south is a response to cold weather.</span>
<span>A.
Roots B.
Stem C.
Xylem D.
Phloem
The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.
The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant.

Answer:
In a fair test two or more things are compared. In order for a test to be fair or scientifically sound, children are required to ensure only one thing (this is called a variable) is changed.
For example, if testing which material is the most waterproof by pouring liquid onto a selection of different materials, in a fair test only the type of material (the component you are testing) should be changed. Therefore all other elements (the type of liquid used, the amount of liquid used, the distance the liquid is poured from, the speed at which it is poured and the size of the material) must remain the same each time the test is carried out. It would be unfair or an unscientific test if, for example, 1000ml of water were poured onto a piece of foil and 2ml of milk poured onto a piece of foam – you would not be able to fairly compare the materials.
hope this will help you!!!.....
