Answer:
Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.
"Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," said Christopher Thawley, graduate student at Penn State at the time of the study and first author of the paper. "Usually when researchers look at how native species might respond to these kinds of threats, they might measure one characteristic of the animal and at one or a few sites. In this study, we looked at three separate characteristics of eastern fence lizards from thirteen sites spanning a thousand miles and found that these lizards are capable of adapting in a concerted way to meet the threat of invasive fire ants, and in a relatively short time frame."

Why is systems thinking important?
Systems thinking ignores the details of a system and just looks at its overall function.
Systems thinking ranks the parts of a system in terms of most important to least.
Systems thinking allows us to understand all the parts that make up the whole system.
Systems thinking examines how a system affects human life.
Answer:
Systems thinking allows us to understand all the parts that make up the whole system.
Explanation:
Just took the test
The systems thinking important because, Systems thinking allows us to understand all the parts that make up the whole system. Therefore, option C is correct.
What system thinking ?By considering the world's complexity in terms of links and entire rather than breaking it down into its component components, systems thinking helps us make sense of how complicated the world is. It has been applied as a method for investigating and producing efficient action in challenging situations.
By using a deeper grasp of the surrounding structure and its constituent parts rather than relying just on previous events, systems thinking gives a technique to more accurately forecast future outcomes.
Systems thinking is a discipline in management that focuses on understanding a system by looking at the connections and interactions between the different parts that make up the entire of that defined system. The concept of the "entire system" is a way of looking at an entire organization in relation to its surroundings.
Thus, option C is correct.

Do you think personality
traits are primarily inherited
from your parents or
influenced by the
environment? What is your
evidence you researched?
Personality traits are influenced by a combination of genetic and environmental factors. Research suggests that both genetics and the environment play significant roles in shaping an individual's personality.
Studies on twins and adoption give proof that genetics affect personality. When opposed to fraternal twins, who only share 50% of their genetic makeup, identical twins, who share 100% of their genetic material, frequently show stronger similarities in personality traits. This shows that certain personality traits are influenced by hereditary factors.
Yet, environmental influences also have a considerable impact on personality. Despite having comparable DNA, studies on non-twin siblings reared in the same home have found that they frequently display personality differences.
This shows that the environment, including parental practices, cultural influences, and life events, has a significant impact on personality development.

Explain why a halogen bulb has a longer bulb life than a traditional incandescent bulb filled with argon.
Answer:
The halogen bulb lasts longer because the filament lasts longer. It can have twice the life of an incandescent and use the same amount or slightly less (10%) electricity.
Explanation:
how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by about 200N demonstrate newtons 2nd law
Answer:
The answer is below
Explanation:
Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.
Let F = force, m = mass of object, v = velocity of object, mv = momentum.
F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.
Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:
F = m(dv / dt)
200 N = m[(5 m/s - 0 m/s) / (1 s)]
200 = 5m
m = 40 kg
Convert 6.03 m to km using Dimensional Analysis
Explanation:
[tex]6.03 \: m \times \frac{1 \: km}{1000 \: m} = 0.00603 \: km[/tex]
Which layer of the ocean is the least dense?

Answer:
the deep ocean
Explanation:
goog le
The layer which is closest to the surface is least dense.
What are the layers of ocean?The ocean can be divided into three main layers:
The surface layer (also known as the epipelagic zone), which extends from the surface to about 200 meters deep and is the warmest and lightest layer.
The mesopelagic zone (or twilight zone), which extends from 200 to 1000 meters deep and is characterized by limited light and declining temperatures.
The bathypelagic zone (or midnight zone), which extends from 1000 to 4000 meters deep and is the coldest, darkest, and most pressure-filled layer.
Below the bathypelagic zone lies the abyssopelagic zone, which extends from 4000 to the ocean floor and is characterized by near-constant darkness and extremely cold temperatures.

if you need 2.5 moles of of aluminum, how many atoms of aluminum is this?
Answer:
This can be found by my multiplying number of moles with avogadro number
So we have:
2.5 × 6.022 × 10²³
= 15.055 × 10²³
Therefore there are 15.055 × 10²³ atoms in 2.5 moles of Aluminium

Chlorine reacts very violently. What about its electron shells makes this the case?
Answer:
it readily gains another electron. the outer electron shell is closer to the nucleus, than iodine for example, which makes it less shielded (greater attraction for another electron = violent reaction to get it)
Explanation:
What effect does this added energy have on the temperature, pressure, and number of collisions?
Answer: Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
