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.
Answer: Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. However, too much precipitation can also have a negative impact on human activities, business and industry, agriculture, and the environment. As moist air is forced up the windward slope it expands and cools, eventually causing water droplets to condense when the air is saturated. These droplets form clouds and grow to produce rain or snow that typically falls out on the windward side of the range. ... As air approaches the topography, it slows down.
Explanation:
The question is incomplete. Th ecomplete question is as following:
All of the following protect the skin and mucous membranes from infection EXCEPT
A) multiple layers of cells.
B) tears.
C) saliva.
D) HCl.
E) the "ciliary escalator."
Answer: D) HCl.
Explanation:
- The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.
- Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.
- Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
- The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,
Whereas HCL helps in the digestion process.
Hence, the correct option is D.
