Galileo preformed 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,
Answer:
<u>Both of these are necessary to maintain overpopulation of any species in an ecosystem.</u>
Explanation:
- Predation is an act in which one organism eats another organism present in the ecosystem.
- The one eaten is called prey, while the dominant organism is called Predator.
- Since an ecosystem is made up of many organisms along with the natural resources present in it.
- This gives rise to different species competing against one another.
- If one of these species is at a certain advantage, their population will rise uncontrollably hence to prevent this a predator plays a major role.
- On the other hand, competition is a term which describes the harm caused to two different organisms.
- This is due to the limited number of natural resources like food, water or shelter etc.
- Organisms who are less likely to adapt according to the changing environment ultimately die.
- For example, Plant roots over time lessen the amount of nitrogen present in the soil, causing the neighboring plant to die.
Answer:
Water provides hydrogen and electrons used in producing glucose.
Explanation:
Photosynthesis is process peculiar to green plants and other organisms like algae and some bacteria. Plants synthesize their own food in form of an organic molecule (glucose) by combining carbondioxide (CO2) and H2O in the presence of sunlight. They absorb light energy from the sun to power the first process called LIGHT stage, where NADPH and ATP are produced to be used in the next stage. The electrons used to reduce NADP to NADPH comes from the "PHOTOLYSIS OF WATER"
CO2 is absorbed via the stomata in the leaves of plants. The CO2 is then fixed in the stroma of the CHLOROPLAST when it undergoes series of reactions in the Calvin cycle to produce glucose. However, the glucose molecule (C6H12O6) contains hydrogen which CO2 does not possess, this Hydrogen is provided by water during the light stage where it donated it to NADP+

Hail does form during thunderstorms and when it is below freezing temperatures in the atmosphere. Hail is a super-cooled water vapor and freezes once it comes into contact with the atmosphere.
answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason. ... The two main parts of the cell cycle are mitosis and interphase.
The cell cycle is the replication and reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called Binary Fission, allows for them to live on by dividing into two new daughter cells.cell division takes place in the cell cycle.
Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. ... Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells.
Purpose of Cell Division. Cell division is an essential process for organism creation, growth, and repair. There are two main types of cell division in humans. Cells can divide to make reproductive cells, sperm and eggs.
The cells in our body are highly intelligent. They know when to duplicate themselves and when to rest or stop dividing altogether. ... If the cell passes through each phase and makes it through each checkpoint, then the parent cell replicates and each of the new cells then enter into their first cell cycle.the cell cycle and cell division is very benificial and important for our body.
hope it helps : )
