The Sun's gravity is pulling on Jupiter and keeps the planet in orbit
You would have the same weight on Jupiter as you do on Earth since
weight is a property of the object.
A rocket traveling to Jupiter would just need to travel beyond Earth's
atmosphere before the gravitational force would be zero.
The gravitational force of Jupiter keeps its moons orbiting.
IV.
Which of the statements above are true? Circle all that are correct.
Answer:
The Pull of the Planets is a 30-minute activity in which teams of children model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it has on the surrounding space.
This activity should be conducted after Heavyweight Champion: Jupiter!, which allows the children to discover the force of gravity in the solar system. These concepts involve more advanced science than previous activities in Jupiter's Family Secrets, and they explore more deeply the science of the Juno mission and the rich information it will return to us. Facilitators who choose to undertake this activity should have a firm grasp of the scientific basis so that misconceptions are not introduced to the children.
Explanation:
what is the difference in solubility of triglyceride and the products of their hydrolysis
Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.
Explanation:
Hope this helps.
The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.
Why are triglycerides insoluble?Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.
This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.
Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.
Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.
Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

1. What do you notice about the angle of Earth?
2. How do you think this affects the seasons in different hemispheres (halves) of the world?
Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.

(Choice B)
Chlorophylls absorb light energy, which eventually breaks the bonds of water molecules.
(Choice C)
ATP and NADPH are used for carbon fixation.
Answer:
I think it is Chemical reactions produce glucose, ADP and NADPH
Explanation:
Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.
What is a light-dependent reaction?
A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.
The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.
Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

Use examples to explain how the biosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.
Explanation:
All cells come from other cells. New cells are created by a process called cell division. To start cell division, a cell grows bigger and makes copies of the parts inside it. Then, the cell and its parts separate into two new cells. Each new cell contains the same types of cell parts as the original cell. Later, each of these cells may divide again to form more cells. When a multicellular organism's cells divide, the organism can grow. Each resulting cell is part of that organism. When a unicellular organism divides, each resulting cell is a separate unicellular organism. The micrographs below show cells from two different organisms: Giardia, a unicellular protist, and banana, a multicellular plant. Giardia cells in a banana Which of the following statements are true? Select all that apply.?
a. A rose bush cell can divide to form two rose bushes
b. If the bacterium divides, it will become a multicellular organism
c. When a rose bush cell divides, it copies its parts then divides into two cells
d. The bacterium was formed when another bacterium divided
Answer:
c. When a rose bush cell divides, it copies its parts then divides into two cells and
d. The bacterium was formed when another bacterium divided
Explanation:
C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).
D is correct because bacterium are unicellular organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.

Answer:
the answer is BB, Bb
Explanation:
If brown hair is dominant you need to consider the fact that it cant be bb otherwise she would have red hair because lowercase genotypes mean recessive. this eliminates the first and third answer leaving you with the second and fourth answer and we can eliminate the second answer because it says "what are the possible genotypes" meaning we need to list all the possible answers which leaves you with the fourth option.

Explain step by step or in simple terms how does the body regulate water
Answer:
The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs.

Which of these changes is a possible negative consequence of farmers
allowing livestock to overgraze a pasture?
O A. Desertification
O B. Shortage of freshwater
O c. Deforestation
O D. Abundance of clean air
Given what we know, one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification.
What is Desertification?In simple terms, desertification is when the land becomes so dry and void of life that it can be considered a desert. This can be caused by many factors, primarily the lack of vegetation.How can overgrazing lead to Desertification?Overgrazing can lead to desertification due to the fact that the plants and vegetation are not given the opportunity to regrow.The presence of vegetation allows the soil to remain moist and fertile by moving minerals and water through it. Overgrazing causes a lack of vegetation which creates dry and infertile land, which leads to complete desertification.Therefore, we can confirm that one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification due to the damage caused to the soil in the absence of vegetation.
