Answer:
Kingdom Protista.
Explanation:
This is a perfect behaviour of a slime mold which is known to be of the kingdom protista. Slime molds are usually found in lawns, and on the forest floor, deciduous logs and soil too.
Protists are made up of eucaryotic cells in which the cell structure is complex with a well defined nucleus. Some of them move around with their flagella or by forming pseudopodia also known as their false sheet.
Answer:
Soil
Explanation:
Plants get their nitrogen from the soil. Although nitrogen is present in the air the structure of the molecule is strong and so would require large amounts of energy from the plant to break down.
The breaking down of nitrogen is a process called nitrogen fixation. Bacteria and archaea in the soil convert nitrogen into ammonia; breaking down the tough triple bond of nitrogen to be more readily absorbed by the plant.
The correct answer is: dependent variable.
There are two main variables in an experiment: the independent and dependent variable.
The experimenter changes the independent variable and that has the influence on dependent variable. So, the effect on the dependent variable is tested (observed and recorded).
Protect yourself by following these steps: Treat all blood and body fluid spills as if they were infectious. When providing first aid or CPR, protect yourself first, then treat the victim second. Wear appropriate personal protective equipment: gloves, goggles, etc. as required by the accident.
