Answer the following question given this paragraph: The key to continued growth and repair of plant cells is meristem . Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem at the tips of roots and stems allows them to grow in length. This is called primary growth. Meristem within and around vascular tissues allows growth in width. This is called secondary growth. Q: What is the name of the type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate? Choices: - cuticle - guard cell - bundle sheth cell - meristem A:
meristem
Answer the following question given this paragraph: Bases have a lower concentration of hydronium ions than pure water, and a pH higher than 7. Q: What is the name for substances with a ph above 7? Choices: - acid - nutrient - protein - bases A:
bases
Q: Answer the following question given this paragraph: Why do charges flow in an electric current? The answer has to do with electric potential energy. Potential energy is stored energy that an object has due to its position or shape. An electric charge has potential energy because of its position in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where their potential energy is lower. This is similar to water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What is the scientific term for stored energy an object has due to its position or shape? Choices: - repeat energy - mechanical energy - new energy - potential energy A:
A: potential energy
Question: Answer the following question given this paragraph: Living things are considered to be renewable. This is because they can reproduce to replace themselves. However, they can be over-used or misused to the point of extinction. To be truly renewable, they must be used sustainably. Sustainable use is the use of resources in a way that meets the needs of the present and also preserves the resources for future generations. Q: Why are living things considered to be renewable? Choices: - they inherit traits - they evolve - they decompose - they reproduce A:
Answer: they reproduce

Q: What does the decomposition of dead organisms and organic waste release into the atmosphere, soil, or ocean? Choices: - nitrogen - oxygen - hydrogen - carbon A:
**Answer**
carbon

Answer the following question given this paragraph: We see about six colors in a rainbowred, orange, yellow, green, blue, and violet; sometimes indigo is listed, too. Those colors are associated with different wavelengths of light, as shown in Figure 25.22. When our eye receives pure-wavelength light, we tend to see only one of the six colors, depending on wavelength. The thousands of other hues we can sense in other situations are our eye's response to various mixtures of wavelengths. White light, in particular, is a fairly uniform mixture of all visible wavelengths. Sunlight, considered to be white, actually appears to be a bit yellow because of its mixture of wavelengths, but it does contain all visible wavelengths. The sequence of colors in rainbows is the same sequence as the colors plotted versus wavelength in Figure 25.22. What this implies is that white light is spread out according to wavelength in a rainbow. Dispersion is defined as the spreading of white light into its full spectrum of wavelengths. More technically, dispersion occurs whenever there is a process that changes the direction of light in a manner that depends on wavelength. Dispersion, as a general phenomenon, can occur for any type of wave and always involves wavelength-dependent processes. Dispersion Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Q: What is defined as the spreading of white light into its full spectrum of wavelengths? Choices: - immersion - saturation - combustion - dispersion A:
**Answer**
dispersion
