Problem: I have a new situation: 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. But I can use this background: 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. What is an answer for this question: If Ken wants a dough sample to expand, which yeast should he use, yeast A or yeast B?

A: yeast A
Problem: Given the question: I have a new situation: Two friends were involved in a car crash. they both survived, but Mike had a serious brain injury. Vince was OK, he didn't experience any significant injuries. But I can use this background: A person with a serious brain injury usually suffers permanent brain damage. These brain injuries usually occur when an external mechanical force, such as a violent blow or jolt to the head or body, causes brain dysfunction. An object penetrating the skull, such as a bullet or a shattered piece of the skull, also can cause traumatic brain injury. As a result, the person may have trouble talking or controlling body movements. Symptoms depend on what part of the brain was injured. Serious brain injuries can also cause personality changes and problems with mental abilities such as memory. Medicines, counseling, and other treatments may help people with serious brain injuries recover from, or at least learn to cope with, their disabilities. What is an answer for this question: Which friend experienced problems with mental abilities?

The answer is:
Mike
input question: I have a new situation: Two botanists had different interests, Mike studied only trees and flowers, while Chris was fascinated with studying fungi. But I can use this background: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. What is an answer for this question: Which botanist learned more about parasitic fungi????
output answer: Chris
I have a new situation: High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot. But I can use this background: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] What is an answer for this question: Which lake had less anoxia?
----
Answer: Low lake
Q: I have a new situation: Harry and Kim studied ancient humans. Kim studied a 15000 year-old settlement, before humans invented agriculture, while Harry studied a 5000 year-old village. But I can use this background: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. What is an answer for this question: Which student studied about a village that had a lower birth rate?
A: Kim
[Q]: I have a new situation: Mike lives in a cold mid-western city, where there is not much predator prey interaction. Mike noticed that in his city some squirrels have darker coat, while others have lighter coat. He also knew that darker coats are more suitable in cold environment with less predator prey interaction. He started thinking why the squirrels developed different coat colors. But I can use this background: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. What is an answer for this question: Which coat would most likely become more common, darker or lighter?
****
[A]:
darker
