Answer:
Corona
Explanation:
The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.

Final answer:
Epithelial tissue can be multilayered and waterproof to protect from external threats, or single layered to allow for gas and nutrient exchange. Connective tissue supports and joins other tissues. Nervous tissue conveys information in the form of electrical transmission and is found in the brain and spinal cord. Muscle tissue consists of long, thin cylindrical cells that have specialized proteins for contraction.
Explanation:
The question is asking to match characteristics with their respective tissue types. There are four main types of tissues in the human body: epithelial tissue, connective tissue, nervous tissue, and muscle tissue.
Epithelial tissue is a protective tissue that can be multilayered and waterproof, or single layered to allow for exchange of gases and nutrients. It covers the surfaces of the body, lines the cavities and organs, and forms glands. Examples of epithelial tissue include the skin, the lining of the digestive tract, and the lining of blood vessels.
Connective tissue supports and joins other tissues. It provides structural support, connects and anchors organs, and stores energy. Examples of connective tissue include blood, bone, adipose tissue (fat), and fibrous tissue (tendons and ligaments).
Nervous tissue is responsible for transmitting electrical signals. It forms the brain, spinal cord, and nerves. Nervous tissue allows us to sense and respond to our environment, and it coordinates and controls body functions.
Muscle tissue consists of long, thin cylindrical cells that have specialized proteins for contraction. It allows for movement and generates force. There are three types of muscle tissue: skeletal muscle (attached to bones and responsible for voluntary movement), smooth muscle (found in the walls of organs and blood vessels, responsible for involuntary movement), and cardiac muscle (found in the heart and responsible for pumping blood).

Answer : The correct option is, (2) 10 g of water at 55°C
Explanation :
Average kinetic energy of the gas particle is directly proportional to the temperature of the gas particle.
Formula used :
where,
R = Gas constant
T = temperature
= Avogadro's number
From this we conclude that the kinetic energy is directly proportional to the temperature where 'R' and are constant. That means kinetic energy depends only on the temperature not on the mass.
(Higher the temperature, higher will be the kinetic energy)
Hence, the average kinetic energy of water molecules is greatest in 10 g of water at 55°C.
Final answer:
The sample with the highest average kinetic energy of water molecules is (2) 10 g of water at 55°C.
Explanation:
Kinetic energy is a fundamental concept in physics that describes the energy an object possesses due to its motion. It depends on both an object's mass and its velocity. Objects in motion have kinetic energy, and the faster they move or the more massive they are, the greater their kinetic energy. This energy can be transferred or transformed but is always conserved in a closed system.
The average kinetic energy of water molecules depends on the temperature of the water. The higher the temperature, the greater the average kinetic energy. In this case, the sample with the highest average kinetic energy would be (2) 10 g of water at 55°C. This sample has a higher temperature than the other options, therefore, the water molecules in this sample have the highest average kinetic energy.
