Cooperation is a positive interaction between the two organisms, and predation and competition result in a negative interaction for at least one organism.

Explanation:

predation is preying on the other so its negative for at least one of them.

competition is fighting so its negative for at least one of them.

Cooperation makes them help each other so its positive.

Explanation

The digestive tract carries out the function of peristalsis by moving food through the system.  Peristalsis also removes excess liquid from the body.  Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis.  Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

Answer:

Most mutations are not harmful

Explanation:

but some can be. A harmful mutation can result in a genetic disorder or even cancer. Another kind of mutation is a chromosomal mutation. Chromosomes, located in the cell nucleus, are tiny threadlike structures that carry genes.

The most likely outcome when the scientist changed the size of the container is that the pressure increased.

Option (C) is correct.

When the size of the container is reduced while keeping the temperature constant, the gas molecules experience a decrease in volume. According to Boyle's law (P₁V₁ = P₂V₂), if the volume decreases, the pressure of the gas will increase.

Diagram X represents the initial state with larger volume, and diagram Y shows the final state with reduced volume. Since the temperature remains constant, the pressure must change to counterbalance the change in volume.

As the volume decreases, the gas molecules have less space to move around, and they collide more frequently with the container walls. This increased collision rate results in a higher pressure exerted by the gas on the container walls.

Hence, the most likely outcome when the scientist changed the size of the container is that the pressure increased, which corresponds to option C.

Explanation:

Answer:

if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity

The greater the force that is applied to an object of a given mass, the more the object will accelerate

Explanation:

For example, doubling the mass of an object results in only half as much acceleration for the same amount of force

Answer:

1. Planets; movement of planets around the sun and other stars in the galaxy is kinetic energy

2. Rubber Bands; can be classified as both potential and kinetic energy, depending on the state of the band (when stretch=potential energy; when released=kinetic energy)

3. Rivers; strictly kinetic energy. the water is constantly moving creating kinetic energy.

Have a blessed day

The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.

A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.

Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.

Therefore, option C that is, they  break down quicker than stable isotopes is correct.

Answer:

Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.

OK, you can say:

Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in organic, nonpolar solvents. Natural waxes of different types are produced by plants and animals and occur in petroleum.

Answer:

•  Friction is a force that occurs when two surfaces slide past

one another.

• The force of friction opposes the motion of an object,

causing moving objects to lose energy and slow down.

• When objects move through a fluid, such as air or water, the

fluid exerts a frictional force on the moving object. The

frictional force from a fluid is called a drag force.

• Friction examples: tires skidding to a stop on a road,

sandpaper rubbing against wood, air pushing against the

nose of an airplane

• Friction drag force causes objects to slow down as they move through a

fluid, such as air or water.

• Drag force depends primarily on the following variables:

– Cross‐sectional area of an object moving through the fluid

– Speed of moving object

– Density of the fluid

– Drag coefficient (determined by experiments; related to the shape of

the object)

• Drag force is especially dependent on the speed of an object. As an

object’s speed increases, the drag force from the fluid increases

exponentially.

• For example, when you drive at high speeds, the frictional force of air on

the car increases and fuel economy decreases

If my skater begins at a height of 5 meters, then the skater will have enough total energy to successfully complete the skate park ramp from start to finish

Brainliest me

If my skater begins at a height of 5 meters, then the skater will have enough total potential energy to successfully complete the skate park ramp from start to finish.

If my skater starts at a height of 5 metres, he or she will have enough total potential energy to complete the skate park ramp from beginning to end. Potential energy is a physics notion that is affected by an object's height and mass. Because of its position in a gravitational field, an object at a specific height above the earth has potential energy.

The skater has a particular amount of potential energy connected with their starting height of 5 metres. As they go down the ramp, this potential energy is turned into kinetic energy, or motion energy. As the skater moves down the ramp, their speed rises, as does their kinetic energy.
