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.

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.

from each other towards the POLES of
the cell during:
Cytokinesis
Telophase
Anaphase
Prophase
Metaphase
Please answer I’d appreciate it a lot
Answer:
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
Explanation:
Answer:
Anaphase
Explanation:
Anaphase is when the sister chromosomes seperate towards the poles of the spindle.
If spindle microtubules fail to bind some kinetochores in meiosis, then most likely: _____________
a. excessive cell divisions will occur resulting an increase in the chromosome number known as polyploidy.
b. the resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.
c. new microtubules with more effective binding capabilities to kinetochores will be synthesized to compensate for the defect.
d. the defect will be bypassed in order to ensure normal chromosome distribution in the new cells.
The example of the Great Barrier Reef is used to illustrate,
A) the insignificance of coral reefs
B) the lack of diversity in the ecosystem
C) the consequences of increasing acidity
D) the problems that too much algae can create
The example of the Great Barrier Reef is used to illustrate the consequences of increasing acidity. It is one of the wonders of the natural world.
The Great Barrier Reef represents one of the wonders of the natural world and the largest coral reef system worldwide.
This barrier extends from shallow estuarine regions to the deep marine environment, more than 14 latitude degrees.
Ocean acidification stops the development of the Great Barrier because Reef development is supposed to cease at pH 7.8.

which level of an energy pyramid has the least amount of food energy?
Answer: Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy). As a result, tertiary consumers have the least amount of energy and are therefore at the top of the pyramid (the smallest part).

Explain how ADH is involved in the regulation of water in the body
Answer:
Antidiuretic hormone binds to receptors on cells in the collecting ducts of the kidney promotes reabsorption of water back into circulation, These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
How could the changes made to the amino acid sequence influence phenotype changes?
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Protein structure ordersThe sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).
A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.
Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.
