Answer 1

Answer:

During the day, sand's radiation of the sun's energy superheats the air and causes temperatures to soar. But, at night most of the heat in the sand quickly radiates into the air and there is no sunlight to reheat it, leaving the sand and its surroundings colder than before.The water kept in an earthen pot seeps into the small pores in the pot and evaporates from the surface of the pot. The heat required for evaporation is taken from the water inside the pot, thus cooling the water stored inside. This is the reason why on hot summer days water remains cool in the earthen pot.When we put some acetone or petrol or perfume on our palms, it evaporates. During evaporation, particles of the liquid absorb energy from the surface of the palm to compensate for the loss of energy, making the surroundings cool.Due to the large surface area of hot tea (or milk) taken in the saucer, the evaporation of hot tea (or milk) from the saucer is faster. The faster evaporation cools the hot tea (or milk) much more quickly making it convenient to sip (or drink). Hence, we are able to sip hot tea or milk faster from a saucer than a cup.During summer, we normally wear light-colored cotton clothes. We sweat a lot in the summers. Cotton is a good absorber of water. Thus, it absorbs sweat from our body and exposes the sweat to the atmosphere, making its evaporation faster.

Explanation: All of these answers are correct, I learned all of this whenever I was in fifth grade.

make a list the adverse effects of good governance in the society and nation​

Answers

Answer:

In international development, good governance is a way of measuring how public institutions conduct public affairs and manage public resources in a preferred way. Governance is "the process of decision-making and the process by which decisions are implemented (or not implemented)".[1] Governance in this context can apply to corporate, international, national, or local governance[1] as well as the interactions between other sectors of society.

The concept of "good governance" thus emerges as a model to compare ineffective economies or political bodies with viable economies and political bodies.[2] The concept centers on the responsibility of governments and governing bodies to meet the needs of the masses as opposed to select groups in society. Because countries often described as "most successful" are liberal democratic states, concentrated in Europe and the Americas, good governance standards often measure other state institutions against these states.[2] Aid organizations and the authorities of developed countries often will focus the meaning of "good governance" to a set of requirements that conform to the organization's agenda, making "good governance" imply many different things in many different contexts.[3][4][5] The opposite of good governance, as a concept, is bad governance.[6]

Write about the characteristics of tiger's eyes,ears,nose,sound,and humans

Answers

Answer:

Tigers have forward facing eyes rather than one on each side of their head. This provides binocular vision because each eye's field of vision overlaps creating a three dimensional image. Binocular vision enables them to accurately assess distances and depth which is extremely useful for maneuvering within their complex environment and stalking prey.

Tigers have more rods (responsible for visual acuity for shapes) in their eyes than cones (responsible for color vision) to assist with their night vision. The increased number of rods allows them to detect movement of prey in darkness where color vision would not be useful.

Tigers have a structure at the back of the eye behind the retina called the tapetum lucidum that enables them to have better night vision. This mirrorlike structure reflects light (that has not already been absorbed by the eye) back into the eye a second time to help produce a brighter image. The tapetum lucidum causes their eyes to glow at night when a light is shone on them.

Cats in general have a broad horizontal line of nerve cells near the central portion of their eye that enables them to have better peripheral vision. This characteristic is especially useful for hunting prey that is running across a plain.

Tiger eyes have large lenses and pupils that increase the amount of light let into the eye. This characteristic helps the tiger with night vision and when there are low light levels available.

Research suggests that cats in general are capable of seeing the colors green, blue and possibly red, just in less saturation or strength than we see them.

In addition to the upper and lower eyelids that protect the eye, cats and other animals such as crocodilians (alligators, crocodiles, etc.) have a nictitating membrane on each eye that helps keep it moist and removes dust from the surface.

In general cats require only about 1/6 the light humans do to see.

Explanation:

Touch

Tigers have a well-developed sense of touch that they use to navigate in darkness, detect danger and attack prey.

Tigers have five different types of whiskers that detect sensory information and are differentiated by their location on the body. Whiskers differ from guard hairs in that they are thicker, more deeply rooted in the skin and surrounded by a small capsule of blood. The root of the whisker displaces the blood when the whisker comes into contact with something thereby amplifying the movement. Sensory nerves detect this movement and send signals to the brain for interpretation.

The mystacial whiskers are located on the tiger's muzzle (snout) and are used when attacking prey and navigating in the dark. The tiger uses these whiskers to sense where they should inflict a bite. When navigating through darkness the tiger's pupils dilate to let more light enter the eye to increase their vision. The dilated pupils of their eyes assist their night vision but makes focusing on objects up-close difficult. The tiger's mystacial whiskers help it feel its way through the dark.

Superciliary whiskers are located above the eyes.

Cheek whiskers are located just behind the mystacial whiskers on the cheeks.

Carpal whiskers are located on the back of the tiger's front legs.

Tylotrich whiskers are located randomly throughout the body.

The facial whiskers of the tiger are about 15 centimeters (six inches) in length.

The facial area of the tiger has numerous sensory neurons that can detect even the slightest change in air pressure when passing by an object.

Hearing

The tiger's sense of hearing is the most acute all its senses and is mainly used for hunting. Their ears are capable of rotating, similar to a radar dish, to detect the origins of various sounds such as the high-frequency sounds produced by prey in the dense forest undergrowth.

Smell

The tiger's sense of smell is not as acute as some of its other senses and is generally not used for hunting. They have small amounts of odor-detecting cells in their nose and a reduced olfactory region in the brain that identifies various scents.

Tigers, like other carnivores, have a Jacobson organ in the roof of their mouth. The Jacobson organ is a pouch-like structure located directly behind the front incisors. It has two small openings that direct scent particles from the air as the tiger inhales to nerves located within the structure. The nerves then transmit the message to the olfactory region in the brain that identifies the scent.

Taste

Tigers seem to be able to taste salt, bitter and acidic flavors and to a lesser degree sweetness.
