Julie is a high school softball player and in her last game, she was struck in the head by a wild pitch. She blacked out and her coach called 911. In the ambulance, Julie complained that the paramedics were yelling at her and the sirens must be broken because they seemed very noisy. She wanted to know if there was cotton she could put in her ears because everything was so loud. Where was Julie hit? What is the function of this part of the brain?
Answer:
cerebellum
Explanation:
cerebellum is concerned with the balance and positioning of the body, it receives impulses from the semi circular canals of the ears through the vestibular nerve fibre
I HOPE THIS HELPS.
Cerebellum is the most probable part of the brain which was affected. Julie got hit on the cerebellum which affected her hearing capacity and movements.
What is Cerebellum?
Cerebellum is the part of brain which is located at the back of the head, just above and behind the point where spinal cord connects to your brain itself. Cerebellum is also known as the little brain. It was believed since a long time that cerebellum's job was to coordinate the muscle movements.
The cerebellum is important part of the brain as it adjusts postural adjustments in order to maintain balance. It modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles.
The cerebellum is located at the back of brain. Damage to the cerebellum can lead to loss of coordination of motor movement, inability to judge distance and when to stop, inability to perform rapid alternating movements, movement tremors, and staggering.

What is a transform plate boundary? What happens as a result?
Answer:
Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon.
if two different types of particles have the same speed in a medium,why is chromatography process not suitable? write with a reason.
Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.

Research a scientific belief that was accepted centuries ago, but has since been disproved. How does it support the use of the term "scientific theory" instead of "scientific fact?"
Answer:
In the past was believed that species were fixed entities
Explanation:
Before Darwin's evolutionary theory (in which all living things arise through descendants with modification), Linnaeus had proposed that species were immutable entities. Although it was an erroneous concept, this belief enabled the development of a system for classifying and naming organisms. Indeed, Linnaeus is nowadays recognized as the father of taxonomy to create this system. This example shows that scientific knowledge is not based on factual information, but it is a process that progressively increases our understanding of the real world.
In history, there have been different scientific theories that have generated controversy and have been refuted over the years, for example, the heliocentric and geocentric theories.
A scientific theory is a term that refers to:
A set of concepts, phenomena, and properties, rules, or scientific laws that express the relationships between the observations of these concepts that explain a phenomenon.On the other hand, a scientific fact is a concept that refers to:
A verifiable and objective observation, in which the facts are identified with the observations.According to the above, the geocentric and heliocentric theories can be based on the concepts of fact and scientific theory because the scientific fact allowed the geocentric theory to be raised centuries ago from observation.
However, later this was refuted by the geocentric theory that did present a logical and objectively accepted explanation based on calculations and observation.

What property of a water molecule allows hydrogen bonds to form among adjacent molecules? PLEASE HELP!!
A. the strong covalent bonds that hold the oxygen atom to each hydrogen atom
B. the ionic bonds that form after the molecule separates into a hydroxide ion (OH–) and hydrogen ion (H+).
C. the small size of the two hydrogen atoms compared to the oxygen atom.
D. the polarity of the molecule, which involves a slightly negative oxygen atom and slightly positive hydrogen atoms
Answer:
D
Explanation:
The water molecule is polar because the oxygen atom is more electronegative than hydrogen causing the electrons from the hydrogens to gravitate closer to the oxygen atom. The molecule is like a magnet; the negative oxygen end will want to stick to the positive hydrogen end of another molecule. Hope this helps
The property of a water molecule that allows hydrogen bonds to form among adjacent molecules is as follows:
The polarity of the molecule involves a slightly negative oxygen atom and slightly positive hydrogen atoms.Thus, the correct option is D.
What is the nature of a water molecule?The nature of a water molecule is polar. This polarity of a water molecule attracts other polar molecules through hydrogen bonding.
The partial positive charge on the hydrogen atom attracts the partial negative charge of an oxygen atom and allows them to form adjacent molecules among them with the help of hydrogen bonding.
Therefore, the correct option for this question is D.

Why is the notion of a "missing link" between modern apes and humans inaccurate to scientists?
Group of answer choices
Humans evolved from a common ancestor shared with modern apes, not from modern apes themselves.
None of these is correct.
Humans do not share a common ancestor with modern apes.
Humans arose suddenly from the modern ape lineage due to a single Hox mutation, so there are no intermediates.
Answer:
after reading a bunch, i think its "Humans evolved from a common ancestor shared with modern apes, not from modern apes themselves." so sorry if it's wong! hope it helps <3
Scientists disagree with the idea that there is a "missing link" between humans and modern apes because we did not diverge from modern apes, but rather from a common ancestor with them. Therefore, the correct option is A.
What is the missing link between humans and modern apes?The concept of the "missing link" is no longer considered true or valid by scientists. There is no specific "missing link" species that clearly links contemporary humans with contemporary apes, despite the fact that both modern humans and extant apes descended from a common parent species, which is now extinct.
Instead, the fossil record suggests that various hominin species were present during human evolution, demonstrating a slow but steady evolution of human-like traits. This indicates that a separate animal that went extinct was the common ancestor of modern humans and apes. Because evolution is a gradual change over time with many intermediate forms rather than the instantaneous emergence of a new species, there is no missing link.
Therefore, the correct option is A.

Why did Portuguese sailors round the southern tip of Africa in 1488?
Answer:
In 1488, Portuguese explorer Bartolomeu Dias (c. 1450-1500) became the first European mariner to round the southern tip of Africa, opening the way for a sea route from Europe to Asia. ... A major maritime victory for Portugal, Dias' breakthrough opened the door to increased trade with India and other Asian powers.
Explanation:
Portuguese sailors around the southern tip of Africa in 1488 because his voyage showed that the Indian and Atlantic oceans flowed into each other.
Why southern tip of Africa named the cape of good hope?The Portuguese navigator Bartolomeu Dias gave the Cape its original name, the Cape of Storms, in the early 1500s. Later, it was changed to Good Hope to draw more travelers to the southern African coast-passing Cape Sea Route.
The Flying Dutchman supposedly resides at the Cape of Good Hope. The ship is crewed by tortured and ghostly sailors, and according to mythology, it is destined to endlessly beat its way across the nearby waters without ever succeeding in reaching the peninsula.

100 points! Complete the simple sugar molecule Glucose. Please fill out the diagram of the molecule and provide the link of the website or picture you got the answer from. H = hydrogen O = oxygen C = carbon
Answer and Explanation:
Glucose is a hexose with six carbon atoms. It is also an aldose, meaning that it has an aldehyde group, CHO in its first carbon atom. The molecule also has hydroxyl groups, OH linked to the carbon atoms.
Its linear structure shows six carbons united in a line. One of its carbon atoms is linked to a carbonate group, H-C=O. The other five carbons are linked to the hydroxyl groups, OH.
In an aqueous solution, the glucose molecule turns to the ringed or cyclic structure, as a result of the reaction among the first carbon and the oxygen of the hydroxyl group linked to the fifth carbon.
You will find the complete glucose molecule in one of the attached files (named glucose), plus the linear and cyclic structure in the other file (named glucose1).
