Answer:
B. The Earth would only have two large convection currents. The power of Earth's spin to turn flowing air is known as the Coriolis Effect. If the Earth didn't spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole.
Explanation:
At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning. Even braking to a halt over a minute would mean everything experienced a sideways deceleration of three-quarters of Earth’s gravity, so ‘down’ would feel like it was at an angle of 38° from the vertical. That’s enough to knock over most buildings.
If it slowed down over several years, it would still be a disaster. Without centrifugal force, the oceans would move towards the poles, dropping ocean depth by 8 km around the equator. Since this is less than the depth of the ocean there, Earth’s water would be divided into two huge polar oceans separated by a belt of land in the middle. Everything north of Spain would be underwater, as well as all of Antarctica.
Once Earth doesn’t spin on its own axis, a day lasts as long as a year. Everywhere receives six months of daylight, gradually heating up the planet to well over 100 °C. The huge central continent would get the hottest, and any remaining lakes and rivers would boil away and be blown to the poles by fierce winds. Even primitive life would only be possible along a narrow strip at the coast.

In primary mutant screens, A) mutant flies are identified by morphology and then the mutant genes are isolated and studied. B) mutant flies are created by RNAi using random RNA sequences and then the genes affected identified. C) mutant flies are created by gain-of-function expression of random genes. D) two mutant flies are mated to determine if there is an effect on morphology.
Answer:
A) mutant flies are identified by morphology and then the mutant genes are isolated and studied.
Explanation:
The visualization of mutant flies is done with an experiment, where drosophila flies, also known as fruit flies, are captured and placed in closed bottles. The bottles have a mixture of banana and agar so that the flies can feed for a period of 15 days. During these 15 days, the flies made several crosses and over time, it will be possible to identify the appearance of mutant flies as a result of the number of crosses made inside the bottle. The mutant flies will be identified when the researcher is able to observe flies with legs, eyes and wings in different numbers than what is presented in a normal fly.
After being identified by their different morphology, the mutant flies will have their mutant genes isolated and studied.

Evidence collected from a victim at a crime scene includes the following:
3rd instar of a blowfly
Hair that is black and crescent shaped, with a fragmented medulla
Black soot in the lungs
What inference can be made about the victim using the evidence?
The victim has African ancestry and may have died in a fire four days ago.
The victim has European ancestry and may have died in a fire over a week ago.
The victim has Asian ancestry and was likely killed elsewhere by fire two days before.
The victim has European ancestry, and the body was burned after death four days ago.
'The victim has European ancestry, and the body was burned after death four days ago'.
What do you mean by victim?
Victim is a term used to describe an individual who has suffered harm, injury, or loss due to the actions of another person or entity. Victims can suffer physical, emotional, psychological, and financial harm. Victims may also suffer from secondary victimization, which is when they experience further harm due to the reactions of others to their victimization.
The 3rd instar of a blowfly indicates that the body had been dead for four days. The hair suggests that the victim likely had European ancestry, as crescent shaped black hair is common in people of European descent. The presence of black soot in the lungs indicates that the body was burned after death.
Hence, option D is correct.

Explain how each of the following concepts relates to the scenario:
. Phobia .
Sympathetic nervous system
• Intrinsic motivation
• Positive reinforcement
• Extraversion
• Altruism Elaborative rehearsal
Answer:
See explanation below
Explanation:
Phobia: Phobia refers to an extreme and irrational fear of something. It can also be an aversion to something. Philip has a fear of public speaking that began when he forgot a speech in elementary school.

Can anyone do a summary about any New York Times Article. It needs to be a Science article. 3 paragraph minimum. Thanks
Answer:
In the New York Times article, "The Search for Life on Venus," by Kenneth Chang, the author explores the possibility of life on Venus, the second planet from the sun. In this article, Chang examines the various theories surrounding the possibility of life on Venus, including the potential for habitable clouds in the planet's atmosphere. He also discusses the potential for future exploration of Venus, including the possibility of sending a robotic spacecraft to the planet's surface.
Chang explains that the conditions on Venus are hostile to life, with temperatures reaching up to 860 degrees Fahrenheit and a crushing atmospheric pressure 90 times that of Earth's. However, the clouds of Venus may be a more hospitable environment, with temperatures ranging from 40 to 80 degrees Fahrenheit and a pressure closer to that of Earth's. This has led some scientists to speculate that microbial life may exist in these clouds.
In conclusion, Chang's article provides an interesting overview of the possibility of life on Venus. While the surface of Venus is too hostile for life, the clouds may provide an environment where life could exist. Future exploration of Venus may help to answer the question of whether life exists on the planet.

Explain the processes of headward erosion and stream piracy
Headward erosion is the upstream erosion of a stream channel, while stream piracy occurs when one stream captures the drainage of another stream, causing it to divert its flow.
What is headward erosion?The process of headward erosion can lead to stream piracy when the channel of one river extends far enough upstream to intersect with the channel of another river. When this happens, the more powerful river may start to capture the flow of the weaker one, gradually eroding its channel and redirecting its water into its own channel. This can cause significant changes to the landscape and ecology of the affected areas, as the water flow and sediment patterns are altered.
Both headward erosion and stream piracy are natural processes that occur over long periods of time, and they can have important implications for the evolution and development of river systems. They can also have significant impacts on human activities, such as agriculture, infrastructure, and land use, especially when they result in changes to water flow or drainage patterns.
