What are the parts of the human brain?

The forebrain is in charge of movement, sensory processing, learning, memory and language, states the Serendip Studio. The limbic system, consisting of the hypothalamus, thalamus, amygdala and hippocampus, is located in the cerebrum, and it primarily has control over emotions. The neocortex is composed of the frontal lobe, which is essential for reasoning; the parietal lobe, which is associated with movement; the occipital lobe, which is affiliated with visual processing; and the temporal lobe, which is essential for perception and auditory stimuli, memory and speech recognition.\nThe primary ..

What is 250 kph converted to mph?

Though the metric system is an internationally sanctioned decimal system of measurement, some countries have not adopted it.\nThe United States, for example, uses miles per hour to measure speed. Canada, Australia and many European countries measure speed in kilometers per hour. Conversion from kph to mph, and vice versa, is particularly important for travelers between countries that use different measures of speed on their roadways.

What is Mars' revolution?

The total circumference of Mars' orbit is about 888 million miles, compared with approximately 584 million miles for the orbital circumference of Earth. Mars' revolutionary orbit is also about 5.6 times more elliptical than Earth's, accounting for the large difference in orbital circumference. Mars follows its revolutionary path at an average speed of 53,858 miles per hour and comes within 128,409,598 miles of the Sun at its closest approach.

What are disadvantages of crude oil?

The biggest disadvantage of crude oil is the threat it poses to the environment. As it burns, it produces carbon dioxide, which pollutes the breathing air and corrodes the ozone layer. In cases where transportation by pipe is not up to standard, the oil may leak into the ground, polluting the soil and affecting micro-organisms. Transportation by trucks, on the other hand, destroys roads and poses risks of fires in cases of accidents.\nLike refined oil and petroleum, crude oil can also be used as fuel for burning. Unfortunately, it is not renewable, unlike other fuel resources. As such, uncontr..

How is fog created?

Typically, fog forms when the relative humidity is near 100 percent, and it is not considered fog unless it reduces visibility to less than 1 kilometer (0.6 miles). Fog also forms when warm air moves over a colder region. This is known as advection fog, and happens frequently in coastal areas when warm moist air moves onto cooler land. A similar variety is steam fog, which forms over water when a current of much colder air moves over a body of water such as a lake.\nIt is possible for the temperature of the water droplets in fog to be below freezing. This supercooled water tends to freeze on c..

What are the five stages of seed germination?

Successful germination depend on several factors occurring in harmony with one another. The seed must first be viable, or alive, and in most cases, it must have undergone a period of cold temperatures. This process is called stratification. When the right combination of water and warmth is present, the seed coat ruptures, allowing the radicle to emerge. This initial root also serves to anchor the seedling to the soil so that small amounts of water and wind pose less of a threat to its survival.\nAfter the radicle develops small root hairs that begin to take nutrients from the soil, the first s..

What is the function of the oral cavity?

As part of the digestive tract, the oral cavity is where food is chewed and saliva is produced to help propel food toward the stomach. The upper portion of the oral cavity is where the hard and soft palates are located, with the tongue serving as the primary organ in the area.

What are the parts of a hurricane?

The strongest winds and rains occur in the eye wall of a hurricane, while the weakest winds and lightest rainfall occur in the eye. The eye of the hurricane may not contain clouds, and the sky can appear clear and peaceful.\nIn counter-clockwise moving hurricanes formed in the northern hemisphere, the most active part of the eye wall is to the right of the eye in an area called the right-front quadrant. In addition to having heavier wind and rain, this quadrant is the most likely part to form high seas and storm surges during landfall. When the eye wall contracts, the maximum wind speed increa..

What are advantages of solar energy?

Most solar power is harnessed with solar panels that use semi-conductors to convert the collected energy into electricity. In addition, solar water heaters have replaced traditional water heaters in many homes. Other benefits of solar energy include their low maintenance design, near-silent operation, low impact on the ecosystem and the ability to power homes in far-off areas.Solar power does have some disadvantages as well. Solar energy does not work at night and can become less potent on cloudy days. As of 2014, scientists were still working on a way to effectively store the energy collected..

Who was astronaut Kalpana Chawla?

Kalpana Chawla grew up in Karnal, India. She was interested in spaceflight from an early age and completed a PhD in aerospace engineering in 1986. In 1988 she joined the team at NASA's Ames Research Center and was selected as an astronaut candidate in 1994. Chawla graduated as part of the 15th astronaut group in 1995.\nChawla served as mission specialist and robotic arm operator for STS-87, aiding in an EVA operation that captured a malfunctioning Spartan satellite after a failed launch. She logged over 372 hours in space during the mission.\nChawla was chosen as mission specialist for ST..
