The statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.
What do you mean by Evolution?Evolution may be defined as the change in the characteristics of a species over several generations and relies on the process of natural selection.
Wisdom teeth are evolved in humans because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose.
Therefore, the statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.
What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.
integumentary and lymphatic systems
PLZZ HELP QUICKKK
The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Due to technical problems, you will find the complete explanation in the attached files.
Do all please thank you. If not some is ok.
Answer:
1. Increases
2. Decreases
3. Increases
4. Decreases
5. Increases
6. Increases
Explanation:
Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.

Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules

A virus has wiped out the grasshopper population in the area. What effects to the ecosystem will most likely occur?
Answer:
Those who prey on grasshoppers will have their population decline while the grass population will rise.
Explanation:
Organisms need food to survive. If their food is gone, they won’t thrive as well. This isn’t saying they’ll go extinct, as they may have other food sources, but life will be harder with one food source gone. Since grasshoppers eat grass, the grass population will rise some due to a lack of predation. Hope it helps :)

Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Answer:
the force is push and the reaction is moving forward.

Which statements describe social behavior? Check all that apply.
On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. Which type of reproductive isolation operates to keep the mosquitofish isolated, even when fish from different ponds are reunited in the same body of water
Answer:
The correct answer is - Behavioral isolation.
Explanation:
In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.
It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.

required to be older
than representatives
Answer:
Hello There
I think #1
Explanation:
To guarantee senators' independence from short-term political pressures, the framers designed a six-year Senate term, three times as long as that of popularly elected members of the House of Representatives. Madison reasoned that longer terms would provide stability.
