12. Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley
team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but
hiked at high altitude, where there is much less oxygen. Which team probably had an easier time
hiking?
a
Both teams had an easy time hiking because their digestive systems broke down proteins
into amino acids for cells to release energy.
b
Neither team had an easy time hiking: the Valley team's cells needed more glucose from
broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from
air.
С
The Mountain team had an easier time hiking: their cells released energy from protein
reacting with glucose, which was broken down from starch in the digestive system.
d
The Valley team had an easier time hiking; their cells released energy from protein breaking
down in the digestive system, which then combined with oxygen in cells.
Answer: B. Neither team had an easy time hiking; the Valley team's cells needed more glucose from broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from air.
Explanation:
Before the hiking by the scientists, we are told that the Valley team ate a lunch of mostly protein while the Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen.
Based on the above, none of them had an easier time hiking. This is because since the cells of the Valley team who mostly ate protein, need glucose in order for a reaction to occur. For the Mountain team, even though they are a mixture of starch and protein, they went higher which reduced where there was less oxygen. This will have resulted in a hard time for them.
Therefore, neither had a easy time hiking. The correct option is B.
Credibility is essentially the believability of the study, and it is determined by both the trustworthiness and expertise of the researcher. Recently, concerns have arisen over Nalgene drinking bottles and the chemicals they may be releasing into the water. Two scientists publish their findings. One who works for a major Nalgene producing company, the other does not. Which scientist is more credible?
Answer:
The scientist who has no conflict of interest is, in principle, more reliable
Explanation:
All scientific publications must include a Declaration of Interest (also known as Disclosure Statement) by which authors state that there's no personal or financial interest that might be affecting the objectivity of their investigations, results and conclusions. If no conflict exists, the author should indicate that "there is no conflict of interest". In this case, the scientist who works for a Nalgene producing company should state that it is a potential conflict of interest.

Chloroplasts contain chlorophyll a, chlorophyll b, and carotenoids. Why is this important in the process of photosynthesis? Support your answer with facts.
Answer:
Explanation:
Photosynthesis is the process by which green plants synthesize their food from carbon dioxide and water by using the green pigment chlorophyll generating oxygen as product.
Chlorophyll "a " absorbs light from the orange-red and violet-blue areas of the Electromagnetic spectrum. Also Chlorophyll a transfers energy to the reaction center and donates two excited electrons to the electron transport chain
Its main role is as a primary electron donor in the electron transport chain. So the energy from the sun will ultimately become chemical energy that can be used by the plant for cellular processes.
Chlorophyll "b" absorbs blue light. The main role is to expand the absorption spectrum of organisms.
Plant can absorb more energy from the high frequency blue light part of the spectrum. Its presence in cells helps plant convert a wider range of the energy from the sun into chemical energy.
Carotenoids are usually red, orange, or yellow pigments, and include the compound carotene. These compounds are composed of two small six-carbon rings that are connected by a "chain" of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments.
Answer:
The presence of chlorophyll a, chlorophyll b, and carotenoids in chloroplasts allow plants to absorb more energy from sunlight by absorbing multiple wavelengths. Chlorophyll a absorbs blue-violet light and red light. Chlorophyll b absorbs mostly blue light. Carotenoids absorb violet, blue, and blue-green light. The pigments together, therefore, are able to absorb a wider range of wavelengths.

Explain what might have happened to make a drop of salt water from the ocean become a drop of freshwater in Falls Lake?
Answer:
Evaporation
Explanation:
The drop of salt water is heated by the sun. The H2O molecules start to move faster and the liquid water becomes a gas. The salt is left behind as the water droplets are carried in a cloud. Then they fall as rain which is freshwater.

One argument in response to the "Commons" idea is that private land ownership will prevent a "tragedy" from happening. Based on the article, do you agree or disagree? Why?
Answer: agree
Explanation:
The common argument which is based on shared assets and the behavior of each individuals.
When the land ownership becomes private a tragedy is avoided as each individual treats the land with care and caution, unlike when it’s a common( shared) where they all don’t care what happens to the land or it’s aftermath so far they all gain personally. So yes when it’s a private land then and then do they truly prevent any tragedy associated with common to happen.

A collision between which two types of crust will most likely produce a mountain range?
Answer:
Be more specific
Explanation:
Answer:
A convergent boundary
Explanation:
Convergent boundaries are pieces of crust that collide against each other. They push upwards, and that land that is pushed upwards is a mountain. Mount Everest is a good example. It was made in two tectonic plates, and since these plates are still pushing upwards to this day, this mountain grows around 40 cm each year. I hope this helps!
