As marine animals swim in the ocean, their muscles are doing work and converting energy from the animals' food into which of the following types of energy? a) nuclearb) chemicalc) solard) kinetic

Option (D)

Explanation:

The kinetic energy of an object refers to the energy that is gained because of the motion of the object. In simple words, it can also be considered as the amount of work required to accelerate a body from rest to a certain velocity. Due to this, the body attains a kinetic energy.

Mathematically, Kinetic energy is given by-

K.E= 1/2mv²

where, K.E is Kinetic energy

m=mass of the object

v=velocity of the object.

Thus, when the marine animals swims in the oceans, their muscles performs some work. As a result of which the energy obtained by the food changes into Kinetic energy due to which they are able to swim and their body is in motion.

Hence, the correct answer is option (D).

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
