Answers
Answer:
a.) 12 Newtons
b.) Same Direction
c.) Unbalanced
Explanation:
The system shows 2 individual forces:
A force of 5 N pulling the box LEFT
A force of 7N pushing the box LEFT
Both forces are LEFT, so they have the same direction.
Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:
Resultant force's magnitude is then: 5N + 7N = 12N
Resultant force's direction: unchanged = LEFT
Since the resultant force's magnitude is not 0, the system is unbalanced.

How does a magnifying glass make an object look bigger and closer?
Answers
Answer:
Any converging lens that has a small focal length (several centimeters) can be used as a magnifying glass. The observed object is placed in front of the magnifying glass so that it is located between the lens and the focus (closer to the focus).
Explanation:
It consists of only one condenser lens of small life (a few centimeters).
The observed object is placed between the magnifying glass and its focus (closer to the focus)
The observer sees an upright and enlarged figure of the object.
In order to like clear video ("sharpen"), the magnifier zooms in or out of the subject.
When the character is most clearly seen, we can find ourselves on a given high species.
For a man with normal eyesight, it is about 25 cm.

Answer: Bad gene
Explanation:
They can cause and become a ''bad'' gene, a gene that is not good.
That gen is not good because it can become permanently activated or turned on in the times where it is not supposed to happen and because of that cell can grow out of control. When a cell is growing out of control it can be really bad because it can cause cancer.

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
an increase in food availability
an increase in pollution
a decrease in tuna fishing
a decrease in tuna predators
Answers
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
Other options, such as an increase in food availability, a decrease in tuna fishing or a decrease in tuna predators, are environmental factors that contribute to increased genetic variability.Answer:

In a two-compartment model of a cell with a K - and Cl --permeable membrane and a 10-fold excess of KCl in the inside compartment, how would the membrane potential change if all the beginning KCl solutions (including inside and outside) were replaced by NaCl
Answers
Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.

3. Complete redamation of mined land is the solution you practiced in this cookie mining lab. What reasoning supports this solution as one that will provide the largest benefits and least costs to society and the environment ?
4. Legislation requiring the reclamation of the land makes mining more expensive. How important is this constraint to achieving complete reclamation of mined land?
Answers
Answer:
1. Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local.. 2.Mining in the real world can affect society, ecosystems, and the environment of a specific region because all the minerals that you are looking for won't be right where you want them to be. It is not going to be in the same area. Instead, it will be scattered throughout the mines and you will have to search for them. 3.Students act as mining engineers and simulate ore mining production by using chocolate chip cookies. They focus on the cost-benefit analysis of the chocolate ore production throughout the simulation, which helps them understand the cost of production. As students “mine” with tools such as paperclips and toothpicks, they keep records of their costs—land (cookie), equipment used, cookie size before and after production, and time spent. While the goal is to make as much profit as possible, other costs and goals are taken into consideration—as in real-world mining engineering. For example, mining engineers also consider the resulting amount of destruction to the lithosphere when deciding the best method to obtain ore. Thus, a line item for land reclamation cost is included from the beginning. A provided worksheet serves as a profit and loss statement. 4.Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.

The extraction of minerals or other geological elements from the earth is known as mining.
How does mining affect society, ecosystems, and the environment?Society: Mining increases social conflicts, causes relocation of the community, affects the health of humans and animals and causes loss of land. However, it helps increase economic growth. Ecosystem: Mining adversely affects biodiversity and destroys the habitat.Environment: Mining causes erosion, sinkholes, deforestation, overuse of water resources, waste disposal issues, acidification of soils and water bodies, and their contamination.What is land reclamation?It is the process by which the mined lands are filled, thereby producing land that can be used. They can be used to restore the environment. However, the ecosystem and society's restoration takes a long time.
Is it beneficial?While the land that cannot be used now has been restored, the materials that have been used have been taken from a source, and that can lead to changes in the ecosystem at the source.
What is the reasoning that supports land reclamation as the solution?The goal is to produce as much profit as feasible. When determining the optimum approach to collecting ore, mining engineers, take into account the amount of lithosphere destruction, and hence, from the start, land reclamation costs are included.
What is the role of mine reclamation legislation?It ensures that land reclamation activities are planned before a mine is licensed or started.
