NO FAKE ANSWERS AND NO LINKS. Now that you know about newton’s first law of motion, how might you use it to ride a skateboard safely?
Answers
Answer:
Newton's first law of motion states that an object at rest will remain at rest and an object in motion will stay in motion unless it is acted on by an unbalanced force. To start a skateboard rolling over a level surface, you need to push off with one foot against the ground.
Explanation:
Hopefully this helps :)
Answer:
In the absence of friction or any other unbalanced force, a skateboard in motion will just keep on rolling. Explanation: If an object is already in motion, inertia will keep it moving. Therefore, a skateboard at rest will remain at rest unless acted upon by an unbalanced force.
How does the amount of sugar affect the carbon dioxide production in yeast?
Answers
Answer: Sugars cause the gluconeogenesis process to start, as well as trigger, unexpected hormone like responses causing a faster metabolism, which in return, increases carbon dioxide levels (Verstrepen, 2004). This is why both CO2 and ethanol can be used to measure the rate of respiration for yeast. Many countries that produce a high amount of sugar
Explanation:
A low water concentration means a
solute concentration
high
low
Answers
Answer:yes
Explanation: when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.
Answer:
high
Explanation:
If the concentration of the water is low ten that means the solute-solvent ratio is high which means the solute(solid dissolved) is high

What is the best example of how nervous system maintains homeostasis
Answers
Answer:
The nervous system regulates breathing and heartbeats but it's also responsible for regulating the core temperature of the body. So when conditions are too warm or hot and body temperature rises, the blood vessels can dilate causing heat loss. Nerves can trigger sweat glands to release fluid that evaporates and cools the skin so that body temperature begins to lower to a normal condition.
