Why do we have high and low tides?
Answer:
It often accompanies a new moon and when the moon is closest to the Earth. The moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause high and low tides. Tides move around the Earth as bulges in the ocean.
Sun Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune
At a large desk or on the floor, choose a position to represent the Sun, and place Mercury a few inches from it. Predict the relative distances between each of the other planets, and space them out accordingly. Do you think the average distances between each of the planets stays relatively consistent or varies greatly? What leads you to this conclusion?
Assuming we are to perform this model to scale, with accurate and reliable data, we can conclude that the average distance between each of the planets would increase as we go.
Most science projects which involve creating a model of the solar system place each planet in perfect orbits at equal distances from one another. Accurate scientific data tells us that this is not the case.
The position of the planets in our solar system follow two trends:
Not all planets have perfectly circular orbits, and therefore are not always at the same distance The spacing between planets grows as we get further from the sun.The distance from the sun weakens the effects of the Sun's gravity on the planets, causing them to be further apart as well as causing increasingly erratic orbits. This leads us to the conclusion that the average distance between planets varies greatly.

A. Look at the arrows pointing toward atmospheric CO2. What are the two major sources of
atmospheric carbon?
Although the diagram is missing in this question, we can confirm that two major sources of atmospheric carbon are the use of fossil fuels and the natural ocean-atmosphere exchange.
What sources add carbon to the atmosphere?The most harmful of the sources mentioned is the one caused by humans. The burning of fossil fuels such as the oil we use to power cars and other motor vehicles adds tons of carbon into the atmosphere every day.
On the other hand, there are also naturally occurring sources for atmospheric carbon, such as the ocean or the respiration process of animals.
Therefore, we can confirm that two major sources of atmospheric carbon are the use of fossil fuels and the natural ocean-atmosphere exchange.

Based on the test results, are the worm neurons alive?
Answer:
Yes
Explanation:
In the inner-world perspective of the simulation, the worm is absolutely alive as it is obeying the laws of physics as presented by the simulation.
I HOPE THIS HELPS!!!!!
Since it is adhering to the simulation's depiction of the rules of physics, the worm neurons appear to be completely alive from the simulation's inner-world perspective.
What is the worm?The worm is a frequently utilised organism in neuroscience research, because of the limited amount of neurons it contains For instance, the hermaphrodite form of the worm contains 302 neurons in its nervous system, as opposed to the 86 billion neurons found in humans.
Every animal requires a brain to survive, and worms are no different. Their brains control movement, sensory perception, and any other physical processes essential to their existence. A worm cannot, however, use its brain for thought.
