Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time

One of the satellites of Pluto has an orbit like _____.
the satellites of Jupiter
the Earth's moon
the satellites of Uranus
Titan
Answer:
THE SATELLITES OF URANUS!!
Explanation:
The other answer was WRONG! One of the satellites of Pluto has an orbit like the satellites of Uranus.
Here is a quote from my textbook:
Therefore, the moon remains over one side of Pluto all the time and can never be seen from the other side of Pluto. Like the satellites of Uranus, Charon's orbit is perpendicular to Pluto's orbital plane.
Answer:
Satellites of Uranus is the answer!!! So the other person was correct!!!

How does niche affect organisms populations in an ecosystem
Answer:
Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
Explanation:
A species' ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population a more simple definition is if two species have the same niche, one species will exclude the other.

Answer:
B. Heating Water
Explanation:
Well I said so and I am never wrong XD JK. Because the molecular motion increases and it doesn't decrease. I would go on a longer explanation but I don' have the time so mark me branliest plz. HAVE A MERRY CHRISTMAS AND A HAPPY NEW YEAR!!
The physical change of heating water increases molecular motion which is incorrectly displayed in the table.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

How does the body obtain glucose?
Answer:
When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
Answer:
By breaking down and synthesising carbohydrates
Explanation:
When the mouth consumes starch contained or carbohydrate foods, and it passes through the oesophagus to the stomach, starch enzymes are released to break down the complex sugars to a simpler monossacharide sugar called glucose.

What is it that the molecules are trying to achieve as a result of passive
transport?
Answer:
The molecules are trying to achieve equilibrium.
Explanation
In cells, molecules will migrate through the phospholipid bilayer during passive transport, a form of simple diffusion that does not use the energy currency, ATP.
This layer serves as a selectively-permeable membrane; its hydrophilic heads are drawn to water (seen looking outward), while its hydrophobic water-repellent tails face each other, allowing water molecules to diffuse down the concentration gradient through the membrane.
This typcally continues til the molecules gain equilibrium or balance. At equilibrium, molecules neither enter nor leave the cell through passive transport.

Termites are insects that feed on wood, which contains cellulose. Scientists have observed that some termite species prefer wood that has been attacked by fungi. Construct an explanation for this observation.
Answer:
The termites and the fungi possess a symbiotic relationship because they rely on each other for survival. The fungi digest cellulose (that the termites can't digest) from the wood, and in turn, the termites provide the fungi an environment where they can grow and prosper. This explains why termites prefer a wood that was inhabited by fungi. This symbiotic relationship explains why termites prefer the wood that is inhabited by fungi.
Explanation:
(see above)
The best explanation for this observation is that Termites and the fungi engage in symbiotic relationship.
What is symbiotic relationship?Symbiotic relationship is a mutual relationship that occur between two organisms in which one organism benefits and the other organism neither benefit or loss.
Termites benefit by getting the nutrient they desired fro. the wood eaten by fungi.
Therefore, The best explanation for this observation is that Termites and the fungi engage in symbiotic relationship.

One impact of climate change has been the loss of ice sheets in Antarctica and Greenland, resulting in a rise in global sea levels. Which of these describes a potential way this could directly influence human activity?
Answer:
Impact of Climate Change (Global Warming) - glacier melting & global see level rise : influence on human activity
Explanation:
Extreme Flooding - High sea levels imply more inflow into other water bodies like rivers, lakes etc Biodiversity Loss - Many organisms can continue their existence only on extremely cold glaciers - eg (blue bear)Further accelerated global warming - Glaciers have important role in absorbing earth heat, maintaining its coolness. Their melting leads to further global warming. Scarcity of freshwater - Glaciers & snow (salty) water cant be consumed. Increase in this water has reduced proportionality of freshwater that can be consumed1. Briefly describe what is happening at each phase of
meiosis.
Answer:
Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = x
That equation has not any solution, because it reduces to 5 = 0, which is an absurd.
So, the conclusion is that information given by Jenna is wrong.
It is logical: if the difference of the ages is 5, in five years Jenna will have 10 years more than what her sister had 5 years ago, no 5 as she told Jessica.

A child has been born prematurely and is experiencing severe asthma like symptoms. Exposure to what most likely affected cell differentiation in the growing embryo
Answer: Carbon monoxide
Explanation:
Carbon monoxide is a gas that is tasteless, colorless, and odorless, that is formed when wood, charcoal, gasoline is burnt.
When breathed in, carbon monoxide is harmful as it displaces the oxygen that is in the blood and this leads to the deprivation of the brain and other vital parts of the body of the oxygen that's is required for daily functioning.
Exposure to carbon monoxide is most likely affected cell differentiation in the growing embryo. When the pregnant woman inhales smoke, this affects the oxygen in the baby's bloodstream as it's being replaced by carbon monoxide and there's shortage of oxygen.
This affects the cell differentiation in the growing embryo and can lead to the child been born prematurely and can also lead to severe asthma like symptoms.
