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:
The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on
approximately 8300 lane miles of Maine's state roads. They usually plan on an average of about 30 treatable events in a winter. This
includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a
storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout
the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative
effects on plant life and aquatic ecosystems. What is something your community can try to reduce the environmental impact of
salting? Select ALL that apply.
A)
Buy more snow plows and use less salt.
B)
Ban all salt based solutions in the state.
C)
Provide incentives to consumers who install snow tires for increased
traction.
D)
Provide tax incentives to municipalities who will install solar panels that
heat water in pipes embedded in the road.
Wet the pavement before applying brine solutions to help the salt adhere
to the road, cutting back on how much they use.

Why can cells in the bone marrow produce both red and white cells
Answer:
1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.
Explanation:
2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.
3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place

How does galaxy composition typically relate to the age of the stars in the galaxy? (1 point)
Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.
Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.
Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.
O Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.
H
Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
Components of a StarDustGasThe age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.
