A tissue sampler that is being used for a medical procedure is placed inside a saline solution. Unknown to the medical team, the saline solution is hypertonic. Deduce what will happen to the cells within the tissue sample
Answer: Water will leave the cell and the cell will shrink.
Explanation:
Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment. The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:
Hypotonic: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell. Hypertonic: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell. Isotonic: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.

What information can a scientist learn directly from a single fossil? O A. What the organism looked like B. How the organism is related to organisms on Earth today C. How many offspring the organism produced D. How long the organism lived
Answer:
A. What the organism looked like.
Explanation:
From a single fossil you can see what the organism looked like, but you need more than one fossil to know how long it lived. You can't determine how many offspring an organism produced from any fossil. And how the organism is related to organisms on earth today can be learned indirectly from fossils, using other information and technology.

What do you think selectively permeable means?
A. The membrane lets nothing in or out.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
C. The membrane lets everything in and out.
Answer:
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
Explanation:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.

Smoking Doesn’t Just Hurt Your Health
(excerpt)
The arguments about smoking are usually centered around its effects on the health of smokers and nonsmokers alike. Entire ad campaigns have been developed around the idea of educating smokers about the risk that smoking poses to their health. Chances are you’ve encountered the photo of that diseased lung in your health class. Lawsuits against tobacco companies have gained a lot of media attention. Cities have gone so far as to ban smoking inside buildings, restaurants, and bars. But have you ever stopped to think about what smoking does to the environment?
It is easy to guess that smoking might pollute the air. Did you know that tobacco smoke contains more than 4,000 chemicals? Fifty of those chemicals are known to cause cancer, and two hundred are known poisons. Think about the fact that 20 percent of Americans smoke. Can you imagine how many chemicals are released into the air each year?
Cigarettes also account for an estimated 1.7 billion pounds of trash each year. Some people say the ban on smoking indoors in some cities could contribute negatively to this statistic. Because people are smoking outside, the number of cigarette butts they leave behind may increase dramatically.
A.
Smoking pollutes the air in public places, such as buildings, restaurants, and bars.
B.
Smoking not only produces negative effects on human health but also on the environment.
C.
Smoking damages the environment more severely than it damages human health.
D.
Smoking increases water pollution when cigarette butts are dumped into waterways.
E.
Smoking harms wild animals by polluting and destroying their natural habitats.
Answer: B. Smoking not only produces negative effects on human health but also on the environment.

A cell that utilizes NHEJ to repair a double-stranded DNA break which occurred in the open reading frame of a gene is susceptible to indels resulting in a frame shift mutation and ultimately a non-functional protein. False True
Answer:
True
Explanation:
The non-homologous end-joining (NHEJ) pathway is a DNA repair pathway used to repair double-strand breaks that can occur throughout all cell cycle phases. Conversely to the homologous recombination (HR) pathway, the NHEJ pathway does not need a homologous template at the DNA double-strand breaks ends and therefore NHEJ is an error-prone repair pathway that may cause mutations within the repaired region of the DNA. The NHEJ pathway is well-known to induce indels (i.e., insertions and deletions) mutations that shift the reading frame of the protein (i.e., frameshift mutations), thereby leading to a completely different translated protein from the original one.
