Four children pull on the same stuffed toy at the same
time, yet there is no net force on the toy. How is this
possible?
Answer:
The forces the children are exerting on the object balanced one another.
Explanation:
Equal forces acting on an object in opposite directions.
Hope this helps!
Answer:
Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The net force is the sum of all of the forces acting on an object. If the children pull on the toy with the same force in opposite directions, the forces will be perfectly balanced and cancel out, leaving a net force of zero.

what is the role of the blood vessels
Answer:
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

What is the source of sediment? A. fragments of other rocks B. chemicals and minerals dissolved in water C. sea shells D. all of the above
Answer:
D: All of the above
These are all sources for sediments
The correct option is D. all of the above are a source of sediments.
What are sediments?
According to geologists, sediment is any solid Earth surface material that can be transferred and dumped in a new location, whether it be on land or in water.
Because sediment particles are easily picked up by water, wind, and ice and transported to new locations, erosion is a significant driver of sediment mobility.
Pebbles and gravel are deposited further downstream, notably in lowland deltas where river mouths open up to the ocean, as water runs over land and through the creek and river basins.
Therefore, The correct option is D. all of the above are a source of sediments.

What do you think a wave interaction is?
Answer:
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These two ways that waves may interact with matter are called reflection and refraction .

the sequence of the bases in DNA is most important for which of the following?
A. allowing the DNA to have the shape necessary for replication.
B. preventing mutations from occurring during DNA replication
C. helping from the sugar-phosphate backbone of DNA molecules.
D. providing the instructions for the traits of an organism.
Answer:
D. providing the instructions for the traits of an organism

It can't be A because RNA is used for replication not DNA
It can't be B because mistakes in the RNA are what causes mutation.
It can't be C because sugar phosphate wouldn't be in the nucleus.

Coal, a fossil fuel made from the remains of swamp plants, has been found in Antarctica. Which of the following is the most reasonable explanation for how this is possible when 98% of Antarctica is now
covered in ice?
The coal was transported by animals that ate the swamp plants.
The climate of Antarctica has become milder due to its closeness to the ocean.
The climate of Antarctica was probably much warmer in the past than it is today.
The coal was transported through large convection currents and uplift in the mantle.
Answer:
The climate of Antarctica was probably much warmer in the past than it is today.
Explanation:
There are little things living there now. Coal takes millions of years to form. There must have been much more living things there in the past (when it was warmer) to make coal.

Heat Transfer discussion based question
Your response needs to be AT LEAST 2 paragraphs.
DISCUSSION QUESTION: How is thermal energy transferred?
Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.

Jenny brings home a plant with an internal concentration of 25g/ml. She puts the plant in her aquarium and fills the aquarium with water from the tap.
The plant will swell and possibly burst if the cell walls are weak.
B
The plant will wilt and possibly break apart if the cell membranes are weak.
C
The plant will thrive in a new type of environment.
D
The plant will become a creeping vine and grow out of the aquarium.
The plant will swell and possibly burst if the cell walls are weak. So, the correct option is A.
What is Cell wall?A cell wall is an external structural layer that surrounds some types of cells. It may be hard, flexible, or occasionally rigid. It serves as a filtration system as well as structural protection and support for the cell. The cell wall composition varies according to the organism which is permeable in nature
The cell wall isolates the inner elements from the surrounding environment. The cell as well as its organelles are also development in the context, support, and protection by it. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component. If the plant's cell walls are insufficient in the case above, it will enlarge and possibly burst.
Therefore, the correct option is A.

Is this Red blood cell in a Hypotonic, Isotonic, or
Hypertonic solution?
Explanation:
It is hypertonic . Hope it will help you!
Answer:
[tex]\boxed {\tt Hypertonic}[/tex]
Explanation:
The H₂O, or water is exiting the cell, and the result is shriveled up red blood cells.
In a hypertonic solution, there is a greater concentration of solute outside the cell and a greater concentration of water inside the cell.
The water will diffuse through osmosis from high to low concentration, so the water moves out of the cell.
Therefore, this is a hypertonic solution.
While visiting Wave Rock in Australia, you observe streaks of minerals present on the landform. What natural process most likely caused the streaking?
The answer is deposition
Answer:
Deposition would have most likely caused the streaking.
Explanation:
Deposition is the laying down of sediment carried by wind, water, or ice. Sediment can be transported as pebbles, sand & mud, or as salts dissolved in water. Salts may later be deposited by organic activity or by evaporation.
One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid. This causes the water vapor to change directly into a solid. Another example is the soot that is deposited on the walls of chimneys.
