Why is a sidereal day shorter than a solar day on earth?
Nadusha1986 [10]
The Sidereal Day is 4 minutes shorter than the Mean Solar Day, because the rotation of the Earth on its axis, and the orbiting of the Earth around the Sun, are both counterclockwise, as viewed from above (or north of) the Ecliptic Plane. See planetary retrograde motion for an example of the opposite situation.

The reason that the Solar Day varies around the Mean Solar Day is that the Earth moves at different speeds through its orbit around the Sun. This is in keeping with Kepler's Second Law of Planetary Motion.

Please note that the Mean Solar Day changes over a long period of time, due to the slowing of the rotation of the Earth due to tidal forces exerted on the Earth primarily by the Moon. For example, the Mean Solar Day was about 23 hours about 250 million years ago.

Golf courses make use of fertilizers to keep the grass green and healthy. Using your knowledge of osmosis, explain how applying
Nostrana [21]
Osmosis is the diffusion of water. Water tends to diffuse to the area with a higher concentration of solute. (Particles) In this case, Im assuming the fertilizer is the solute because it contains chemicals. Therefore, since water tends to diffuse to higher concentration of solute, the water in the grass will diffuse out to dilute the fertilizer on the surface of the grass. Without water, the grass will be dehydrated and shrivel up and die. Hopefully you find my answer helpful!

Cystic fibrosis is genetic, meaning it can be passed from parent to child. What type of mutation causes cystic fibrosis? somatic
Tresset [83]

Answer: Germline mutation

A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.

In the context of sensory receptors, the intensity of the stimulus is communicated to the brain by varying the _____ of the acti
Ipatiy [6.2K]
The answer to this question would be: frequency

The higher intensity of the stimulus, the higher frequency of the action potential will be sent. The nerve can't send a higher action potential, so it firing at higher at higher intensity instead. So when you felt an intense pain, that means the pain receptor is firing more stimulus per second compared to low or mild pain.
