Answer:
Your answer is 2.
Explanation:
To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. In a two pulley system the MA is 2.

Answer:
Phytoplankton are essential for atmospheric and climate regulation.
Explanation:
Phytoplankton are autotrophs, they use solar energy, along with inorganic carbon and water to produce their own food source via photosynthesis. During photosynthesis, they also produce oxygen, integral for the planet's atmospheric composition.
At their large biomass, phytoplankton contribute to a majority of the oxygen used by consumers (most animals).
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Along with fossil fuels, human agricultural practices have contributed large amounts of CO2 to the atmosphere, This causes global warming, a major environmental crisis- global warming also leads to landmass loss, biosphere disruption and reduces biodiversity in mass extinction events.
Phytoplankton carbon cycling produces organic matter which functions as carbon sinks in our oceans. Thus, as phytoplankton use large amounts of CO2, they help combat warming cycles, along with producing O2 in atmospheric and climate regulation.
Answer: Density-dependent limiting factors
Answer:
Queen ants have two main responsibilities first, Queens are the founders of all ants colonies. A queen and will leave the colony she was born into a mate with flying male ants. After mating, she will scurry off to find a new location for her nest, lose her wings and lay her first hatch of eggs.
