What are biomes?

Biomes can be defined as regions specified by particular biological and geographical communities that evolved because of the shared regional climate of that region.

In the natural world, symbiotic partnerships can take one of three main forms: parasitism, commensalism, or mutualism. Mutual benefit: both parties win.

There are certain populations that work together. The right response is option C since this is a situation in which individuals of the same species collaborate in order to survive.

Answers

It’s D as it’s reached the bottom the potential Energy is converted into kinetic energy

At the bottom of its swing, it has the lowest potential energy. Option D is correct.

What is potential energy?

Potential energy is the energy stored in an object due to its position relative to other objects.

Here,
At the top of its swing, a pendulum has zero potential energy. At the bottom of its swing, it has the lowest potential energy.

In the case of a pendulum, potential energy is stored in the pendulum due to its position relative to the Earth. The higher the pendulum is, the more potential energy it has, and the lower it is, the less potential energy it has.

At the bottom of its swing, the pendulum is at its lowest point, so it has the lowest amount of potential energy. Thus, the answer is D) Zero.

A. electricity
B. electric force
C. electric force
D. electric chargeelectric charge

Answers

Answer:

I would say electric current, but since that isnt a given choice, i would choose electricity.

Explanation:

an electric force is an attraction between two charged particles, not the flow.

electric charge is the cause of the electric force.

again im not sure, hope this helps!

The correct term for the flow of charged particles is known as electric current or electricity. Hence, option A is correct.

What is Electrical energy?

Charged material experiences a force when exposed to an electromagnetic field because of the fundamental characteristic of electric charge. It's conceivable for electrical ions to be positive or negative. Two charges that are opposed to one another repel one another.

An object with no net charge is said to be "neutral." Classical electrodynamics refers to the older theory of how charged particles interact, and it is still valid for problems that do not necessitate accounting for quantum phenomena.

The net charge of an isolated system, which is the total of the negative and positive charges, cannot change since electrical current is a conserved property. Electric charge is carried by subatomic particles.

Therefore, it concludes that flow of charged particles is termed as electricity.

How does the velocity of a moving object depend on the choice of frame of reference?

Answers

Imagine you threw and caught a ball while you were on a train moving at a constant velocity past a station. To you, the ball appears to simply travel vertically up and then down under the influence of gravity. However, to an observer stood on the station platform the ball would appear to travel in a parabola, with a constant horizontal component of velocity equal to the velocity of the train. This is illustrated in Figure 1 below.

(Path of the ball as seen by an observer on the train and an observer at the station.)

The different observations occur because the two observers are in different frames of reference. A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another.

The laws of physics are the same in all inertial frames (this is known as Galilean invariance). Put in another way, there is no experiment that you could do to determine which reference frame you are in (Einstein used this hypothesis to devise the theory of Special Relativity). This means that we can address problems in any reference frame to give an equivalent solution.

Why is cellular respiration essential for homeostasis? (4 points)

To create energy that the cell can use

To make air in the body

To remove oxygen from tissues

To make new types of cells

Answers

1Cellular respiration supports homeostasis to maintain the stability of body. ATP is produced during cellular respiration that provides energy to perform several body functions such as muscle contraction and nerve conduction which are responsible for the maintenance of homeostasis
2. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available
3. The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
4. The regulation of tissue oxygenation is based at the start from the ability of the respiratory system to fully oxygenate the arterial blood which the heart then delivers to the peripheral tissues. The need for different levels of respiration varies with the physiologic state of the organism (e.g., sleep, excitement, exercise). The respiratory system must try to maintain constant levels of O2, CO2 and H+ in the arterial blood which then ensures relatively constant levels of these important substances in the interstitial fluid. For O2, one needs an adequate supply to meet cellular metabolic requirements. For CO2 and H+, one needs to maintain the acid–base status of the body's cells
5. New cells are created from a process called cell division. The new cells are produced when a cell, called the mother cell, divides into new cells called daughter cells. When two daughter cells have the same number of chromosomes as the original cell, the process is called mitosis
To create energy that the cell can use hope this helped x

The unicorn suddenly ran through the school at 5.6 m/s and it has a mass of 450 kg. What is the unicorn’s kinetic energy?

Answers

Answer:

KE = 567000 J

planation:

The kinetic energy of the unicorn can be find out from its mass and velocity. The kinetic energy of unicorn is 7056 J.

What is kinetic energy ?

Kinetic energy is a form of energy on an object generated by virtue of its motion. It is related to the mass and velocity of the object by the expression written below:

Ke = 1/2 m v²

When an object starts moving from rest, its potential energy converts to kinetic energy. As the mass and velocity increases, kinetic energy increases.

Given that, m = 450 kg

v = 5.6 m/s

then , Ke = 1/2 450 kg × (5.6 m/s )² = 7056 J.

Therefore, the kinetic energy of the unicorn is 7056 J.
