Can connecting rods be reconditioned? Reconditioning connecting rods is an important and often times a necessary step in the engine rebuilding process. The processes used to recondition connecting rods vary a little from engine to engine but the end result should be the same – straight rods and smooth, round bores. When should I replace […]

How are green algae and plants similar? Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch. Do plants and green algae store […]

How is wind energy different from energy from fossil fuels? Wind is an emissions-free source of energy Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and […]

What is the measure of how much matter makes up an object? Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance. Is […]

Are hot and cold receptors the same or different? Warm receptors will turn up their signal rate when they feel warmth—or heat transfer into the body. Cooling—or heat transfer out of the body—results in a decreased signal rate. Cold receptors, on the other hand, increase their firing rate during cooling and decrease it during warming. […]

What happens during a cross over event? Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. During which process do Tetrads line up across […]

Are embryonic stem cells pluripotent? Embryonic stem cells (ESCs) derived from the inner cell mass of a blastocyst are pluripotent stem cells with unique properties of pluripotency and self-renewal. They can divide indefinitely in vitro, while maintaining the capacity to generate all the cell types of an adult organism. Why are embryonic stem cells considered […]

Is biodiesel a biofuel? Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called “biofuels,” to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology. What are considered Biofuels? Biofuel, any […]

Why does lettuce wilt if it sits in salad dressing for awhile? This is because the water is trying to even out the concentration of salt in the dressing and the leaves, hence lots of water is needed in the dressing to reduce the concentration of salt. This means the water from the leaves goes […]
