What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents? Primary forces are thermal expansion and contraction of water, the stress of wind blowing over the water, and density differences between water layers. Secondary forces and factors are the Coriolis Effect, […]

What happens when two magnets are placed side by side?
What happens when two magnets are placed side by side? Opposite poles of a magnet attract each other, whereas like poles repel each other. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible. Is Venus a permanent magnet? Venus is a […]

Where an object is located in relation to another object?
Where an object is located in relation to another object? 7.1 An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is […]
How are amino acid sequences used to figure out if two species are closely related?
How are amino acid sequences used to figure out if two species are closely related? Molecular clocks are used to determine how closely two species are related by calculating the number of differences between the species’ DNA sequences or amino acid sequences. These clocks are sometimes called gene clocks or evolutionary clocks. What are the […]
What are the materials needed for photosynthesis?
What are the materials needed for photosynthesis? To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food. What is the photosynthesis equation? The process of photosynthesis is commonly […]
What is p the probability of success What is 1 p the probability of failure?
What are the types of screw threads?
What are the types of screw threads? Clamp screws come in many forms. There are Standard threads, ACME threads, Buttress threads, and Square threads. Each of these threads may be used in clamps and vises for different reasons. What is the use of screw? The most common uses of screws are to hold objects together […]
Is rock a fossil?
Is rock a fossil? Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks.
