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.

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.

When he discovered that blood is pumped from the heart to the body, and back to the heart, ________ had a difficult time getting people to accept his discovery because it went against the ancient teachings of _______.
Answer:
1 - William Harvey
2 - Galen
Explanation:
Galen, who postulated that blood was produced continuously in the liver and absorbed by the body (not recirculated), served as the Roman emperor's personal physician. For 1500 years, his theories about human anatomy went unquestioned until Harvey's proposal in 1628.
When he discovered that blood is pumped from the heart to the body, and back to the heart, William Harvey had a difficult time getting people to accept his discovery because it went against the ancient teachings of Galen.

Explanation:
Ik this is for ap3x :)
Keep on cheating yall
C. A kangaroo rat's body temperature can vary with the time of day.
A hypothesis is a tentative explanation or prediction that can be tested through observation or experimentation. In this case, observing a desert animal's behavior for 24 hours provides an opportunity to gather data and test hypotheses related to the animal's behavior or physiological responses.
Option C, "A kangaroo rat's body temperature can vary with the time of day," is a hypothesis that can be tested by monitoring the body temperature of kangaroo rats at different times throughout the day and night.
Kangaroo rats are small desert rodents known for their adaptations to survive in arid environments. They are nocturnal and have specialized physiological mechanisms to conserve water. Given their activity patterns and the fluctuating temperatures of desert ecosystems, it is reasonable to hypothesize that their body temperature may vary with the time of day.
To test this hypothesis, researchers could observe and record the body temperature of kangaroo rats over a 24-hour period, using non-invasive methods such as temperature sensors or thermal imaging. By comparing the data collected at different time points, they can determine whether there are significant variations in body temperature throughout the day and night.
If the observations show consistent changes in body temperature corresponding to the time of day, it would provide evidence to support the hypothesis. On the other hand, if there are no significant variations or if the data contradicts the hypothesis, it would suggest that other factors are influencing the kangaroo rat's body temperature regulation.
Overall, option C presents a testable hypothesis that can be investigated through direct observation and data collection, providing insights into the physiological responses of kangaroo rats to the diurnal variations in their desert habitat.

Explanation:
First of all the mitochondria is the power house of a cell. Then a chloroplast is one which contains chlorophyll in which photosynthesis takes place.
Plants make use of photosynthesis to synthesize nutrients from carbon dioxide and water. If the chloroplast is damaged that means the plant would wither but it may not likely die since the mitochondria is unharmed.

Answer:
The correct answer is: marking or tagging pathogens so phagocytes can find and ingest them.
Explanation:
Opsonins are proteins of great importance in our immune system that can intervene in the innate and the adaptative immune response thanks to the complement system.
Opsonins can recognize pathogens or diseased cells and bind to their surface molecules, thus marking them for other cells (particularly phagocytes such as macrophages and neutrophils) to phagocyte (eat) them. This process is hugely important in removing potential threats and non-functioning cells.

Develop an argument as to whether or not the structures and functions of the nervous system work to help prevent injuries. Use evidence and real-world knowledge to support your argument.
Answer:
Yes.
Explanation:
Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
