Describe the structural and compositional layers of Earth.
Answer:
The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite. The Earth has an outer core that is liquid and an inner core that is solid.

how does the respiratory system aid the digestive system
a. the lungs take in oxygen to aid in food digestion
b.the lungs take in carbon dioxide to aid in food digestion
c. the expand the diaphragm, which helps to push the stomach during digestion
d. the lungs contract the diaphragm, which helps to push the stomach during digestion
PLEASE HELP ASAP ! :)
Answer:
The respiratory and digestive systems work together to power the body. A properly functioning respiratory system delivers adequate oxygen to the blood. Because the digestive system breaks down food and uses muscular contractions to move food through the digestive tract, it needs oxygen to function properly.

What is the purpose of DNA?
Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation: Hope this helps. Branliest if you can plz.

Glyptodon is a giant, armadillo-like animal that once lived on Earth and weighed over 2000 kilograms (kg) and lived almost exclusively in warm, wet coastal regions. In many ways it resembled the 4 kg armadillo that lives today. From the information given, what is the probable reason Glyptodon is not alive today?
A. Predators hunted the animal for food to the point of extinction.
B.The animal could not adapt to environmental changes.
C.The animal ate too much food.
D. The Glyptodon had genetic variation.

Explanation:
1. What direction does water move if a cell is placed in salt water?
2. What direction does water move if a cell (slightly salty) is placed in pure distilled water?
3. What direction does water move if the concentration of salt is the same inside and outside of the cell?
4. What organelle of the cell controls movement in and out of the cell?
Answer:
the water will move into the cell
Explanation:
the hypotonic solution has a higher water potential than that of the cell, so water will enter the cell from a region of higher water potential to a lower water potential down a water potential gradient across a partially permeable membrane via osmosis.

What elements make up brass alloys?
Answer:
Brass alloy is a composition of elements that define the structural properties It typically is composed of 66% copper and 34% zincI do exams and quizzes if your interested :)Which statement refers to convection?
Sunlight travels through space without the aid of fluids or solids.
Land and ocean absorb and re-emit heat from the sun.
Some of this energy is reflected off Earth's atmosphere.
Warm air rises and takes heat with it; eventually it cools and sinks.

How will you know if a chemical change has occurred when the reactants are combined? Use evidence and scientific reasoning to support your answer.
Answer:
I would know if a chemical change is occurred if a new material is formed which doesn't share any characteristics of the reactants example if we expose iron to water and air a new material is formed (rust) which doesn't share any characteristics of iron,water or air.
(I'LL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST!)How do the properties of magnets allow them to be useful to society?
Brass is an alloy of copper and zinc. Bronze is an alloy of copper and tin. Alloys are commonly used in manufactured items because the properties of these metal mixtures are often superior to a pure metal.
Answer:
Correct, in structures of material you can calculate youngs modulus and the module of elastics and rigidity to calculate breaking points as well as structural integrity.I do quizzes and exams if your interested:)Which energy source can be used as an energy source that may otherwise be thrown away?
solar
wind
water
biomass
or geothermal?

Please help me out with this question if you help me I will give you the brain thing and extra points. 2/9 image below.
Answer:
B
Explanation:
Due to the force of Inertia
How do you put this in your own words-
This amount depends on the latitude of the area. Latitude is the angular distance in degrees north and south from the equator. Different latitudes receive different amounts of solar energy.

Answer:
Third Law of motion. (answer C)
Explanation:
This is an example of Newton's Third Law of motion which normally translates into Action/Reaction. That is : the expelled air exerts a force in the direction opposite to that of the motion of the air that goes out. It is the same as propulsion in a rocket.
Dont answer if you dont know What is a difference between complete metamorphosis and incomplete metamorphosis?
Complete metamorphosis has 3 stages and incomplete metamorphosis has 4 stages.
Only complete metamorphosis has the nymph stage.
Complete metamorphosis has a larva and pupa stage.
Only insects that undergo complete metamorphosis can fly.
Answer:
The differences between complete and incomplete metamorphosis are many. Complete metamorphosis has 4 distinct stages: egg, larva, pupa, and adult. Incomplete metamorphosis has 3 distinct stages: egg, nymph, and adult.

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.
Multi-celled algae grow into larger organisms through cell division. For one-celled algae, the purpose of cell division is
