Answer:
1) Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force.
2) The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
3) There are the two components of the projectile's motion - horizontal and vertical motion.
4) The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

Which organelles are different between animal cells & plant cells? pls 45 minutes till this assignment is due
Answer:
Plants have cell walls provide support and gives the plant its shape. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food(glucose). Plant cells usually have one or more large vacuole, while animal cells have smaller vacuoles, if any are present.

what happens to waste material in surface mining?
Answer:
Your answer is that mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife

The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.

Which of these statements accurately describes the energy conversion that occurs in cellular respiration?
A) ATP is converted into thermal energy.
B) Chemical energy is converted into ATP.
C) Heat energy is converted into chemical energy.
D) Light energy is converted into kinetic energy into the products.
Chemical energy is converted into ATP in cellular respiration. Therefore, option B is correct.
What is cellular respiration?The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, like oxygen, to generate significant amounts of energy that are used to power the major creation of ATP.
Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.
The primary goal of cellular respiration is the production of energy, even though it can also result in the production of other substances like lactic acid or carbon dioxide. Every biological process requires energy. Therefore, option B is correct.

7. Why is it so unlikely for a girl to get a disorder like Duchenne Muscular Dystrophy
Answer:
Because it takes a very long time and an interesting mindset.
Explanation:
People don't really have an explanation for the things that we do they just suddenly build up inside us
Answer:
This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.

Plants that reproduce sexually generate seeds. These seeds are often dispersed away from the parent, either through wind , animals , or water. Look at the seed shown in this image of bullrush plants. What form of dispersal do you think it uses, and why ?
Can anyone help me in this question
Help!!!
Answer:
wind/water either one.
Explanation:
It can reproduce from rhizomes or seed and uses the wind and water to disperse its seeds.
Based on the appearance of the seed shown in the image of bullrush plants, it appears that these seeds are dispersed by wind.
What are different form of seed dispersal?Seed dispersal is the movement of seeds away from the parent plant, allowing them to establish in new locations and increase the chances of survival and reproduction. There are several forms of seed dispersal, including:
Wind dispersal: Seeds with feathery structures or plumes, such as dandelions, are carried by the wind.Animal dispersal: Animals can carry seeds away from the parent plant in their fur or digestive systems, such as berries eaten by birds.Explosive dispersal: Some seeds are expelled from their pods with great force, such as in the case of squirting cucumbers.Water dispersal: Seeds with waterproof coats can float on water and be carried long distances, as seen in coconut palms.Biotic dispersal: Seeds can also be dispersed by other living organisms, such as ants that carry seeds to their nests and bury them there.Learn more about seed dispersal, here:
