Answer:
In the first generation, the beetles changed to have light spots. The beetles with the light spotted trait had a better chance of survival causing the species evolved to have lighter spots.
Answer:
In the first generation, the beetles with the dark spotted trait had a better chance of survival. The trait mutated over time, causing the beetles with that trait to be darker.
Explanation:
In the picture that I had, it shows that some of the beetles in the first generation started to develop spots on their back or wings. It shows that later down the line, their backs start to get even more darker which means that is must be a trait that mutated over time that would allow the beetles with that trait to be significantly darker. They can't just change their traits if they want to so it would have to be something like mutation that caused it.

For the following elements (Group 1A), Li, Na, K, Rb), which atom is larger overall?
Answer:
The smallest atom you have listed would be lithium (Li).
Explanation:
Lithium is the third smallest atom listed on the periodic table of the elements. It has an atomic number of three, meaning it has three protons in it's nucleus.
Atom size (Atomic radius) increases from UP to DOWN in the same COLUMN(group) of the periodic table. For example, in the first group, the Atomic radius trend from smallest to greatest is: H (smallest) -- Li -- Na -- K -- Rb -- Cs -- Fr (greatest).
Reason is, the increasing energy level (increases from n=1 to n=7) causes the shielding effect increase dramatically. And since the size of atom is mostly consist of electrons, more energy level is filled, the larger the atom will be.)
However, in the same ROW from left to right, the atomic size decreases as the number increases. For example, Li #3, is larger than Flourine (F) with an atomic number 9 because they are on the same ROW.

The diagram illustrates the water cycle.
Parts of the water cycle labeled U through Z. U: Water moving from a lake into the clouds. V: Clouds. W: Water falling from clouds as rain and snow. X: Water moving from ground to the clouds. Y: Water flowing down the mountainside into a lake. Z: Underground water going into lake.
Which process occurs at location W?
precipitation
evaporation
condensation
transpiration
Answer:
The Answer is Precipitation
Explanation:
Look it up on and then also got it right on the Unit Test and the Quiz.
The diagram illustrates the water cycle, the process that occurs at location W is precipitation. The correct option is a.
What is precipitation?Precipitation is any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail.
Precipitation occurs when a portion of the atmosphere becomes saturated with water vapour so that the water condenses and precipitates or falls. Thus, fog and mist are not precipitation but colloids, because the water vapour does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapour to the air. Precipitation forms as smaller droplets coalesce via collision with other raindrops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers.
Precipitation is a major component of the water cycle and is responsible for depositing the fresh water on the planet.
