In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer:
D.) Organism
Explanation:
On the basis of biological organization, one female arctic fox will be considered as an organism.
Biological organization refers to a hierarchy starts from simplest biological structure to complex biological structures that define life, such as from atoms to biosphere.
So, biome is the community of animals and plants having common characteristics according to the environment; species is also a group of living organism sharing similar genes; ecosystem include different groups with the physical (abiotic) environment and organism is the basic living system,that include at least one cell.
So, one female arctic fox will be termed as an organism and the correct option is D.
Answer;
-Kinetic energy
Explanation;
The energy associated with motion or movement is called kinetic energy.
-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.
-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.
-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
It depends on what kind of solution is referred as 0.65 M. If the solution where the red blood cell is present is hypertonic, the red blood cell will shrink. If the solution is hypotonic, the red blood cell will expand. If the solution is isotonic, the red blood cell will not expand or shrink.
