Two students were discussing an article about a possible mission to Jupiter. Several ideas
about gravity came up during their discussion and they are listed below.
1.
II.
111.
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.

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.
The conditions that prompt hemoglobin to release oxygen are:
Decrease in pH (high acidity)ExerciseUnloading of oxygen from haemoglobinHaemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:
Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood. Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.

how long does it take for a photon to travel through the convection zone
Answer:
50 million years
Explanation:
It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.

Onion root cell 3 is the closest to the completion of the cell cycle. Mitosis is
the type of cell division which involves the production of two identical
daughter cells.
Telophase is regarded as the final stage of mitosis before cytokinesis takes
place. In this phase, the chromosomes decondense and the spindle breaks
down.
There is also formation of two new nuclei of the daughter cells which are
separated by the newly formed nuclear membrane which is evident in the
onion root cell 3 thus making it the most appropriate choice.

define the following terms:dispersion and refraction
Explanation:
Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.
In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

DNA technology plays a role in medicine except identifying mutations when EXAMINING paternity. It involves the determination of the biological father.
DNA technologies refer to the genetic engineering techniques used in medicine and biotechnology for diverse purposes.
For example, DNA recombinant technologies can be used to produce insulin, which is a hormone required for the treatment of individuals suffering from diabetes.
DNA paternity tests are genetic tests whose objective is to determine nucleotide (DNA) polymorphisms and thus indicate whether a man is another individual's biological father.

Choose 1 answer:
(Choice A)
Chemical reactions produce glucose, ADP, and NADP^+
(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.
