Can the amount the balloon fills up be controlled by the amount of vinegar or baking soda? Can the amount the balloon fills-up be controlled by the amount of vinegar or baking soda? Yes, if you don’t use the right amount of vinegar or baking soda the balloon will not inflate, if you use too […]
How are metamorphic rocks classified?
How are metamorphic rocks classified? Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. The other minerals have been crushed and deformed into a fine-grained matrix (Mtx). What are metamorphic […]
What is ionized helium?
What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]
What is the relationship between different trophic levels?
What is the relationship between different trophic levels? The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and […]
What are 3 adaptations that allow plants to survive on land?
What are 3 adaptations that allow plants to survive on land? Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue. What challenges did plants have to overcome to live on land? The life on land presents significant challenges for plants, including the potential for desiccation, mutagenic […]

Salamander being an amphibian has a three chambered heart. Which animal has no heart and brain? Jellyfish Do cows have two hearts? How many heart chambers do cows have? […]
Does rubber neutralize electricity?
Does rubber neutralize electricity? Rubber is an insulator. Electricity will always travel “the path of least resistance.” Rubber has a very high resistance, so electricity will go somewhere else to find ground. It doesn’t neutralize electricity. It has a high electrical resistance, making it very difficult for electricity to pass through it. Can insulators prevent […]

Can the scientific method be cyclic?
Can the scientific method be cyclic? How does it work? The scientific method involves a cyclic process of observation, hypothesis and experimentation. Why is the scientific method not really linear? In contrast to the linear steps of the simplified scientific method, this process is non-linear: The process of science is iterative. Science circles back on […]
