The earth, moon, and sun, all move In a synchronized motion together. The Earth revolves around the sun while rotating, as does the moon around earth. But what does this all really mean?
Revolution is the orbit of an object with less mass around an object with more. It is the cause of seasons on earth- Spring, summer, fall, and winter.
Rotation is the spinning of an object on its axis. Earth spins at a tilt of 23.5 degrees. This is why we have day and night.
Let's not forget about the moon! It's accountable for 2 things- the Lunar Cycle and Tides.
The lunar cycle is a series of phases visble in the Night sky. It's starts with a New Moon, then leading to waning crescent, 1st quarter, waning gibbous, full moon, waxing gibbous, 3rd quarter, waxing crescent, and finally ending with another new moon.
Tides are caused by the gravitational pull of the moon. There are 2 major types- Spring tides and Neap tides.
Spring tides are when gravitational pull is greatest towards the sides of the earth. They happen during full and new moon.
Neap tides are the opposite. Gravitational pull is greatest near the north and south poles. They are present during 1st and 3rd quarter moons.
The Earth, sun, and moon play a huge rule in how we perceive the night sky- and on our planet too!

how do plant cells obtain oxygen for respiration [worth 9 marks]
Answer:
As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

Which of the following can you infer from the information in the table below? Hominid species Evidence H. Neandertalensis Physical features include skeleton suited for upright walking, hands, and large brains. Burial sites contain artifacts like flowers, food, and weapons. All fossils found have been radiocarbon dated to be 130,000 to 35,000 years old. H. Sapiens Walk upright, have thumbs used for making tools. Large brains Bury their dead ceremonially. Fossils found in sediment layers containing volcanic ash crystals that are 195,000 years old H. Neandertalensis and H. Sapien were able to mate and produce offspring. H. Neandertalensis is not a direct ancestor of H. Sapien. H. Sapien is a hominid branch that will become an evolutionary dead end. H. Sapien and H. Neandertalensis did not occupy the same geographic region.
We can infer from the information in the table below information about the evolution.
Evolutionary History of Modern Man1) Modern shares a common ancestor with gorillas and chimpanzees.
2) Some species before sapiens sapiens, according to the evolutionary process, are:
AustralopithecinesErgasterRectusNeanderthalensis and sapiens.3) Australopithecines inhabited the arboreal savannas of Africa around 2.8 to 2.3 million years ago.
4)Several species of australopithecines were able to walk upright or semi and had small brains.
5) During this period, Africa was undergoing a series of environmental changes that transformed its arboreal savannas, inhabited by australopithecines, into open savannas.
6) Thus, the australopithecines began to be exposed to predators, due to the decrease in shelters. This fact led to the extinction of most australopithecines.
Only a few lineages were able to adapt and survive, allowing the emergence of hominids.
With this information, we can know a little more about the evolution process of the human species.

How does an enzyme’s active site relate to its substrate?
Answer:
A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex. The products then leave the active site of the enzyme.
Brackish water is common in freshwater wetlands. Please select the best answer from the choices provided T F.
Answer:false
Explanation:
brackish water occurs when fresh water goes into the ocean and mixes.
Brackish water is common in freshwater wetlands. The statement is false
What is brackish water ?
Brackish water with salinity levels between seawater and freshwater, when surface or groundwater mixes with seawater brackish water formed in deep fossil aquifers.
Brackish water is undervalued can be used for irrigation and most industries can’t use it and not fit for consumption by humans or livestock. Brackish water is easier to desalinate than seawater.
The global warming and climate change show an impact on the composition and increased occurrence of brackish water. Due to global salt levels increases, the level of brackish water, increases.

PLEASE HELP!!!! WILL MARK BRAINLIEST!!!!
Answer:
yes, these are isotopes of nitrogen.
Explanation:
Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.

what is pressure and how do we get it
Answer:
pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
Calculating pressure
To calculate pressure, you need to know two things:
Pressure is calculated using this equation:
pressure = force ÷ area.
Suppose a species lives in an ecosystem with unlimited resources and no predators. What is the shape of its population versus time graph? help ASAP
Answer:
D. a curve that increases exponentially as time passes
Explanation:
I just took the test
A population growth curve that increases exponentially as time passes would result if a species has unlimited resources and no predators.
Exponential population growthExponential population growth occurs when a population is capable of reaching its biotic potential.
With unlimited resources and a lack of predators, the population of a species continues to grow exponentially without any hindrance. This result is a J curve.
With limited resources, the population might increase exponentially initially and will level off as the carrying capacity of the ecosystem is reached.
