Ecosystems, the interactive system of living and nonliving organisms in a specific location, CHANGE SLOWLY OVER TIME. When new plants and animals arrive in an area, they either thrive or struggle. Thriving species sometimes displace native species. When this happens, the system as a whole begins to change.
Answer:
b) Tendon
Explanation:
Tendons are fibrous, thick, stiff and flexible structures, with a whitish color, present in different parts of the human body.
They are part of the striated muscle being made up of connective tissue (composed of collagen).
The main function of the tendons is to connect the muscles to the bones. In this way, it helps in the balance of the body and in the development of movements, distributing the forces in the muscles.
As it pulls the connecting bone with the muscle, the tendon creates the movement in order to transmit the force of the contraction to the bone.
In addition, the tendon provides stability to the joints (meeting point between two bones) of the body's joints.

Answer:
an atom with eight protons and seven electrons
an atom with eight protons and eight electrons
an atom with eight protons and no electrons
Explanation:
To tell atoms of the same element, it is safe to look at the number of protons. In neutral atoms, the number of protons will be equal with that of electrons but nonetheless, electrons are easily knocked out of their orbit to create charged atoms. Neutrons, on the other hand, can slightly vary in number creating different isotopes of the element. Changing the protons would change the atom into that of another element. Protons, therefore, are used to place an element on the periodic table.
