What must you do to a circuit before the bulbs will light up? Answer: If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each bulb and they all glow. In a series […]
How long do oxbow lakes last?
How long do oxbow lakes last? When this happens a new, straighter river channel develops—and an abandoned meander loop, called a cutoff, forms. When deposition finally seals off the cutoff from the river channel, an oxbow lake forms. This process can occur over a time from a few years to several decades, and may sometimes […]
What is the effect of increasing light?
What is the effect of increasing light? As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant. Why does […]

What happens when molecules move faster?
What happens when molecules move faster? When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands […]

What is DNA in the environment?
What is DNA in the environment? Environmental DNA or eDNA is DNA that is collected from a variety of environmental samples such as soil, seawater, snow or even air rather than directly sampled from an individual organism. As various organisms interact with the environment, DNA is expelled and accumulates in their surroundings from various sources. […]

What is the difference between state and type of matter?
What is the difference between state and type of matter? The matter is anything that has mass and occupies space. States of matter are the physical form taken by the phases of matter. What are the 2 Changes in matter? There are two types of change in matter: physical change and chemical change. As the […]
