[Q]: I can use this background: However, when going across a period from left to right, the atomic radius actually tends to decrease. Why is this so? Each successive electron is going into the same principal energy level as the previous one, so the total amount of occupied space does not really go up significantly. Additionally, because protons are also added to the nucleus as you go across the row, the pull of the positively charged nucleus on the negatively charged electrons increases. This tighter pull leads to a slight decrease in atomic radius. As a result, the atomic radii of the elements exhibit a periodic trend, gradually tends to downward, but with a sharp spike up whenever electrons are added to a new principal energy level ( Figure below ). Now, I have a new situation: There are two elements, Zaxon and Barton. Zaxon is an element that is further left on the period, and Barton is on the right of the period. Answer this question please: Which element has a weaker pull between the nucleus and the electron?
****
[A]: Zaxon

[Q]: I can use this background: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. Now, I have a new situation: Two siblings were going to school. Mary experienced headaches, so he was sent to the eye doctor. The doctor concluded she was nearsighted and prescribed her eyeglasses. Ben had normal vision. Answer this question please: Which sibling did not spend a lot of time on the computer?
****
[A]: Ben

[Q]: I can use this background: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies. Now, I have a new situation: A female goose now has a large family of chicks, the chicks mostly fend for themselves and can move around almost immediately after being born. A short way away a female dog gives birth to a litter of puppies. These on the other hand are defenseless, cant really move and are blind. They require extensive care from their mother. Answer this question please: Which animal, the baby geese or the puppies, is a precocial species of animal?
****
[A]: geese

[Q]: I can use this background: Tropical forests (rainforests) receive more insolation and rainfall over longer growing seasons than any other environment on earth. With these elevated temperatures, insolation and rainfall, biomass is extremely productive leading to the production of as much as 800 grams of carbon per square meter per year. Higher temperatures and larger amounts of water contribute to higher rates of chemical weathering. Increased rates of decomposition cause smaller amounts of fulvic acid to percolate and leach metals from the zone of active weathering. Thus, in stark contrast to soil in forests, tropical forests have little to no podzolization and therefore do not have marked visual and chemical contrasts with the soil layers. Instead, the mobile metals Mg, Fe and Al are precipitated as oxide minerals giving the soil a rusty red color. Now, I have a new situation: The Farlook forest is classified as a tropical forest, and the Celeste forest is not a tropical forest. Jessica is currently looking for a forest to go camping in and is trying to choose which of these two forests she will visit for a week. Jessica despises camping in the rain and also prefers a more moderate temperature. Luckily, her trip isn't for several months so she has plenty of time to make up her mind. Answer this question please: Chemical weathering impacts which forest more?

[A]:
Farlook
