input question: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations . They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two: A sudden climate change hits Alaska and it starts to become warmer. As a result many species of mammals have started to adapt to the warmer climate and now grow less fur. Given the mammals growing less fur is a beneficial mutation, will less fur become more common or less common????
output answer: more

The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih Two cousins lived 10,000 miles away from each other but often talked about visiting the Hawaiian islands together. Lilly lived in Maine, while Heather lived in Hawaii. Which cousin lived closer to the Big Island of Hawaii?
----
Answer: Heather

Q: Shad are also valued as a sport fish that exhibit complex and little-understood feeding behavior while spawning. Unlike salmon, shad retain the ability to digest and assimilate food during the anadromous migration. Like other fish, their feeding instinct can be triggered by a variety of factors such as turbidity and water temperature. Anglers use both spinning and fly fishing tackle to pursue shad. Spin fisherman use a shad dartjig or a flutter spoon. Some anglers use a downrigger to place the artificial lure at the desired depth and location. This is usually in the channel, or deepest part of the river. Migrating shad tend to occupy the lower portion of the water column which makes this the typical depth of choice for fishing. In the North, April through June is when shad spawn in coastal rivers and estuaries once water temperatures have reached 58 degrees Fahrenheit (14 C). Fishing conditions typically improve as water temperatures warm and flow decreases. Jeff loves to go shad fishing. He prefers using fly fishing tackle and is planning a fishing trip up North with his buddies. They decided to take their trip in May when everyone can get off work over the Memorial Day holiday. Sam enjoys shad fishing as well, but the only time he and his buddies are able to take off work is during their slow season in March. Who will have better fishing conditions and likely catch more shad on their fishing trip, Jeff or Sam?
A: Jeff

Question: Electrons can be removed from some objects using friction, simply by rubbing one substance against another substance. There are many examples of objects becoming charged by friction, including a rubber comb through hair, and a balloon on a sweater. In both these instances, the electrons move from the second object to the first, causing the first object to become negatively charged and the second one positively charged. Friction between the tires on a moving car and the road cause the tires to become charged, and wind causes friction between clouds and air which causes clouds to become charged and can result in tremendous bolts of lightning. Two cities, Appleton and Orangeburg, are approximately 100 miles apart and are currently experiencing different weather. Appleton is windy and cloudy, but Orangeburg has very calm air but is also cloudy. Are the clouds in Orangeburg positively or negatively charged?
Answer: positively

[Q]: Baker's yeast is the common name for the strains of yeast commonly used in baking bread and bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae,[1] and is the same species (but a different strain) as the kind commonly used in alcoholic fermentation, which is called brewer's yeast.[2] Baker's yeast is also a single-cell microorganism found on and around the human body. Ken is a microbiologist. He got two samples of yeasts, yeast A and yeast B, from two different businesses. Yeast A is used in a bakery, and yeast B is used in a brewery. He has to decide the characteristics of each yeast sample for further study. Interestingly, despite all his curiosity, Ken doesn't like any yeast to be around him. Would yeast B more likely to present or absent on human body?
****
[A]: likely to present

Problem: Given the question: Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacterial growth. Robert, a baker, has just baked a large batch of cupcakes for his store. He won't be able to sell all of his cupcakes within the next week, so he has decided to store a portion of them in the freezer to preserve them for later. He is trying to decide if he should store the cupcakes at 0 F or at 10 F in the freezer. Which temperature will result in slower decay of the cupcakes?
++++++++++++++++++++++++++++++++
The answer is:
0 F
