Describe the two functions of the coarse focus knob on the SI V-Scope.
Answers
The coarse focus knob on the SI V-Scope lowers and raises the microscope stage and uses power to focus.
The coarse focus knob on most microscopes is located around the bottom center part of the arm of the microscope as illustrated in the image below. The larger of the two knobs and one that is closest to the microscope's arm is the coarse adjustment knob.
Only the lowest power objective lens should be used with the coarse focus knob. You will only need to utilize the fine focus once it is in focus. With higher lenses, using the coarse focus could cause the lens to fall into the slide.

Analyze and evaluate how natural selection produces change in populations as opposed to individuals
Answers
Answer:
For natural selection to work there must be variation in the population for it to act upon and so ‘choose’ the most fit genes for a particular situation. Populations tend to produce more offspring than the environment can support, and the inevitable consequence of this overproduction of offspring is a struggle for survival. Natural selection creates these selection pressures so the organisims best suited for the environment are more likley to survive and therefore pass on their genes to their offspring.
Natural selection can only happen in a population rather than an individual becasue it is the whole population's characteristics culmalitvley changing to better suit the environment. By passing down favourable traits to their offspring. It cannot happen in an individual because they cannot change their traits to better suit the environment, only pass on their traits to their offspring. A change due to natural selection can take generations
Various amounts of table salt are added to water and its affect on density of water is
recorded.
what is the control and experimental group ?
Answers
The control is the source of the water.
What is control?The control of an experiment is the factor that must be held constant in order for the experiment to be reliable. If these factors are not held constant, then the experimental results are not reliable.
In this case, we are measuring the effect of addition of salt to the density of water. We have to ensure that the water is all taken from the same source so that we can be sure that the density is only affected by the addition of the salt and not other extraneous factors.

One of the main reasons that the American diet is unbalanced
Answers
One of the main reasons that the American diet is unbalanced is because of their high consumption of preserved or canned food and a diet that is rich in fats and calories.
A balanced diet must contain the following seven components: carbohydrates, protein, fat, fiber, vitamins, minerals, and water.Maintaining good health and feeling your best can both be facilitated by eating a healthy, balanced diet. To acquire and maintain a healthy body weight, this entails consuming the appropriate amounts of food and drink, as well as a wide variety of meals in the appropriate quantities.Foods that have been preserved and are not truly fresh are referred to as processed foods. Processes that involve the addition of preservatives include canning, smoking, salting, and curing.Because processed meals are frequently easier to find than fresh foods, many consumers choose them over fresh produce. Fresh goods might occasionally be more expensive than their processed equivalents.Hence, the American diet is unbalanced because of their consumption of processed food.

2 diff ways antibiotics work against bacteria
Answers
Answer:
There are two main ways in which antibiotics target bacteria. They either prevent the reproduction of bacteria, or they kill the bacteria, for example by stopping the mechanism responsible for building their cell walls.
Answer:
Antibiotics can kill bacteria by:
1. Preventing the production of peptidoglycan that forms the cell wall. The cell will continue to grow without developing new cell wall, this causes the already existing cell wall to get weaker which will eventually cause the cell to rupture.
2. Stopping the production of proteins (protein synthesis) which prevents the production of new DNA

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well
as some diseases, such as Alzheimer's, that are caused by proteins that have misfolded. The folding of these
complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even
expensive supercomputers to do this.
A group of researchers at Stanford University developed software that can be used to distribute the processing of data to
anyone who is willing to donate time on their idle personal computers. As a result, the researchers have been able to
achieve protein-folding simulations that are far better than those other computing methods have done. Which statement
best describes the work of these researchers?
Answers
Running an experiment required the researchers to use ingenuity to tackle an issue.
The correct answer is "Running an experiment required the researchers to use ingenuity to tackle an issue."
It is the best choice since researchers can process data on anyone's computer who wishes to lend it to them, thanks to software that scientists created. In other words, they came up with a clever solution to the time and financial constraints that the simulation of these proteins folding had.Since the data can be replicated using the program, the work qualifies as scientific, and the fact that the data were not processed in a single location does not change this.The researchers employed more than just tried-and-true scientific methods. It is not a proven scientific method for anyone to be able to contribute time from their computer using software.In conclusion, the answer given above is the best one.

The statement that best describes a difference between a scientist and an engineer is a scientist would ask, "Why does this happen?" while an engineer would ask, "How can I make this work?"
Scientist indulge in research to know the process behind the things that are happening in either living or non-living matters. They focus mostly to the understand the mechanism so that they could provide a solution. On the other hand, Engineer indulges in making a product based on the recordings from research or it can be novel.
Scientist and engineer can get their inspiration from both nature and human-made things as it is not restrained. It’s not something that can be separated.
An Engineer is focused on meeting the needs of people, while a scientist is concerned with the pursuit of knowledge. But we can’t be certain as knowledge is required for the development. Both are inter-related.
A scientist and an engineer may follow a series of steps or solves problems without a process based on the requirement.

A biomolecule is one that is created by a living thing by definition. Water is therefore the external supply of carbon dioxide that living things use to manufacture proteins to fulfill their energy needs.
Water molecules have a slightly positive and a slightly negative side as a result of the unequal sharing of electrons.
There is neither a positive nor a negative side to some molecules, as ethane.The unequal distribution of electrons within the polar molecule is what distinguishes polar (water) from non-polar (ethane) molecules. Covalent bonds in nonpolar molecules have an equal number of electrons.Within aqueous solutions, water is universalizing everything formed from atoms and molecules.Molecules of two or more substances are combined in a homogenous manner to form solutions.
