Answer:
You’re answer is C
Explanation:
Atoms consist of three basic particles: protons, electrons, and neutrons. The center on the atom is called the Nucleus.
Answer:
as temperature rises, mussles in a crickets body contract more, causing it to chirp more often
Explanation:Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. Crickets, like all insects, are cold-blooded and take on the temperature of their surroundings. This affects how quickly these chemical muscle reactions can occur. Specifically, a formula called the Arrhenius equation describes the activation, or threshold, energy required to make these reactions occur. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly.
Answer:
A
Explanation:
Because there are two DNA strands in the DNA molecule and they both rotate around each other in a helix formation. So two helixes = double helix.
Answer:
False
Explanation:
Igneous rocks need more heat than metamorphic rocks.
Alvin was a deep sea vehicle which was used to explore the depths of the ocean. It sunk but was recovered and recommissioned in 1973 after which it discovered black smokers, a special type of hydrothermal vent which produces super heated water with a highly acidic pH. Thus, the answer is B.
