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.

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.

Which scenario would most likely result in cooperative hunting?
Finches eat grass seeds, but grass seeds are not found in an area during winter months.
A shark eats a certain kind of fish, and the fish swim together when the shark comes close.
Wolves eat rabbits, and the number of rabbits in an area is low.
Lions eat zebra, and there are a lot of zebra and lions living in an area.
Answer:
C. Wolves eat rabbits, and the number of rabbits in an area is low.
Explanation:
Cooperative hunting is a form of animal social behavior that is found common among predators mostly faced with a challenge of effectively finding prey to prey on easily. It involves the cooperation of a group of an animal species that cooperate together to effectively increase their chances of catching preys as well as increase their survival chances in such territories.
A scenario that would most likely result into cooperative hunting is where there are few and limited number of rabbits in an area, and as such, it is difficult to hunt rabbits due to scarcity. In order to increase their chances of catching rabbits, wolves in that area would cooperate together and hunt in packs. This will increase the number of kills they'd make when compared to hunting individually. This ensures there is availability of food to eat and also ensures their survival as a group.

According to US Energy Information Administration data, urban U.S. households own an average of 1.8 vehicles each, compared with 2.2 for each rural household. Urban families also drive about 7,000 fewer miles annually than their rural counterparts, saving more than 400 gallons of gasoline and roughly $1500 at current gas prices. What is one reason for these differences?
Answer:
transportation
Explanation:
looking at nighttime satellite photos that show dark landscapes illuminated by glowing urban dots. On the surface, these seem like clear evidence of city dwellers' oversized energy footprints.
And when comparing big cities and small towns directly, a Philadelphia, Pennsylvania, obviously dwarfs the power consumption of a Philadelphia, Tennessee Urban and rural populations use energy differently, though, which complicates such broad comparisons.
Despite hosting regular traffic jams, cities win the head-to-head efficiency matchup in transportation thanks to their mass transit systems and denser layouts, which promote walking and bicycling. Small-town and suburban residents usually have to drive themselves to get around, which isn't cheap.
According to EIA data, urban U.S. households own an average of 1.8 vehicles each, compared with 2.2 for each rural household. Urban families also drive about 7,000 fewer miles annually than their rural counterparts, saving more than 400 gallons of gasoline and roughly $1,300-$1,400 at current gas prices.

What are the sources of energy for the processes that affect Earth?
Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.

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.

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.
