the relationship is that if the sun stopped spinning, the earth would fly off into space and so the earth needs the suns gravity to keep us alive ^^
Answer:
the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

What kind of material is transported through osmosis?
Answer: water
Explanation: Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

what is the theory of plate tectonics?
Answer: The theory states that the earth's crust is divided into massive slabs known as tectonic plates.
Explanation:
These plates move on the mantle which is a layer made of magma, which consists of semisolid rocks.The heat from earth's core causes convection currents much like in a beaker full of water.But, here the force developed by the magma is so great that it slowly moves the plates like boats on sea over millions of years.
Cells perform many different processes that an organism needs to survive and grow. Which is the main function of the process of cellular respiration?
A. the production of sugar
B. the release of energy
C. the removal of waste products from the cell
D. the formation of new proteins for the cell
The main function of the process of cellular respiration is the the release of the energy. The correct option is B.
What is cellular respiration?Cellular respiration is a biochemical process that disintegrate glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glycolysis is the first step in the process by which cells generate ATP from food. Consider eating a donut. Digestive enzymes convert the donut's starches and sugars to glucose (blood sugar) in your mouth and stomach.
The aerobic process by which living cells break down glucose molecules, release energy, and form ATP molecules is known as cellular respiration.
In general, this three-stage process involves the reaction of glucose and oxygen to form carbon dioxide and water.
Thus, the correct option is B.

What is cell theory?Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Which statement describes an advantage of sexual reproduction over asexual reproduction?
Answer:
One advantage is that secual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.
Explanation:
One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.
What is sexual reproduction?When sperm from a male parent fertilizes an egg from a female parent during sexual reproduction, the result is an offspring that is genetically distinct from both parents.
The genetic diversity of organisms is a result of sexual reproduction. Meiosis, a process that creates sperm and egg cells, is the first step in sexual reproduction.
Because they have half as many chromosomes as the parent, these cells are known as haploids. A diploid zygote is created during sexual reproduction when a male parent's haploid sperm fertilizes a female parent's haploid egg.
Therefore, One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

When an animal cell is placed in this solution, it will shrivel or shrink (get smaller).
When an animal cell is places in this solution, it will burst (get larger).
The cells in our bodies are surrounded by these types of solutions.
- Isotonic solution
- hypertonic solution
- hypotonic solution
Help!! Plz
Answer:
- hypotonic solution, hypertonic solution, isotonic solution
Explanation:
When an animal cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.If an animal cell is placed in a hypertonic environment, water will leave the cell, and the cell will shrink.Our cells in our bodies are made of isotonic solutions. See Khan Academy's "Osmosis and tonicity" article for a further explanation!Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.

Similar results in multiple tests of the claim are a factor found in a scientific claim.
What is a scientific claim?The statements made regarding an issue in the field of science are referred to as a scientific claim. Scientific claims are different from any other form of a claim as they are made after a lot of research and are backed by data.
Science is basically a systemically done study of the world around us. People practising in the field of science are called scientists. They collect data, analyze it and based on this analysis they come to conclusions.
Thus a scientific claim is a statement made after coming to the conclusion after analyzing the data.
Even though, a scientific claim is made after thorough research, not every scientific claim is as reliable. The experimentation and analysis can be subject to various errors which can cause a faulty scientific claim.
Therefore, the factor present in a scientific claim would be similar results in multiple tests of the claim.
