Explain why it is important to be skeptical of statistical results reported in the media.
Answer:
Firstly, many statistics are taken from a small group of people used to represent the general population. Say a news channel reported that 81% of teenagers in America were planning on going to a four-year college. This statistic is most likely taken from a randomly selected group of teenagers, and calculated with a margin of error. Because after all, it's nearly impossible to survey every single teenager in America. This can lead to some statistics that are not really representative of the actual percentage of people. This only gets more likely the larger the general population being "surveyed" is. Another reason is that the media is not always truthful with statistics. Things can be altered and not many people will notice. Hope this helps!

Fruit flies have 8 chromosomes. During mitosis, one cell with 8 chromosomes divided to form 2 cells each with 8 chromosomes.
Do this would mean 8 chromosomes divided by 2 becomes: 8+8 chromosomes. Can you describe three events and their associated cycle phases that make this mathematical impossibility biologically possible. (Think about the chromosomes and DNA strands in the cell)
During DNA replication (S phase), the chromosomes are duplicated, resulting in 16 sister chromatids. During metaphase, the sister chromatids align along the equatorial plane of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, ensuring that each new cell receives a complete set of 8 chromosomes.
During mitosis, the process by which cells divide, the division of chromosomes occurs in a way that maintains the correct number of chromosomes in each resulting cell. The scenario you mentioned, where one cell with 8 chromosomes divides to form two cells each with 8 chromosomes, is possible due to three key events and their associated cell cycle phases:
DNA Replication (S Phase): Before mitosis begins, the DNA in the cell undergoes replication during the S phase of the cell cycle. This means that each chromosome replicates, resulting in two identical copies called sister chromatids. So, in the initial cell with 8 chromosomes, during S phase, each chromosome is duplicated, resulting in a total of 16 chromatids.
Chromosome Alignment and Separation (Metaphase and Anaphase): During metaphase, the replicated chromosomes align along the equatorial plane of the cell. The sister chromatids are connected at a region called the centromere. In anaphase, the centromeres split, and the sister chromatids separate, becoming individual chromosomes. The spindle fibers pull the separated chromosomes towards opposite poles of the cell.
Cytokinesis: After the chromosomes have separated, cytokinesis occurs, where the cell membrane pinches inward, dividing the cytoplasm into two distinct cells. Each new cell receives a set of chromosomes, resulting in two daughter cells, each with the same number of chromosomes as the original cell (8 chromosomes each).
Overall, through the processes of DNA replication, chromosome alignment and separation, and cytokinesis, the division of chromosomes during mitosis ensures that the resulting daughter cells maintain the correct number of chromosomes.

breathing in physical phenomenon. what movement does happen when a person breathe in?
When a person breathes in, the diaphragm contracts and the lungs expand, creating a vacuum that draws air into the lungs. The air is then circulated through the lungs, where oxygen is absorbed and carbon dioxide is released.
What should know about the body parts that functions when you breath-in?The diaphragm is a vital muscle in inhaling (breath-in) and exhaling, separates the chest cavity from the abdominal cavity.
When the diaphragm contracts, it flattens and moves down. This increases the space in the chest cavity, which causes the lungs to expand. The lungs are elastic, so they expand when the space around them increases.

Why is NAD+ so important if the cell takes the anaerobic pathway, so glycolysis to fermentation? Does the atp made in glycolysis depend on the NAD+ conversion to NADH in the first step? I am confused on why NAD+ is so important to atp production
Answer:
NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.
During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.
In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.
Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.
Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.
In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

approximately 30yrs ago a small flatworm native to new Zealand was accidentally introduced into Ireland. the flatworm lives in the soil where it catches live earthworms. it secretes digestive enzymes into them and then sucks up the soluble digested material. the flatworm takes about half an hour to digest a single earthworm.
a) explain the feeding relationships between the flatworm and the earthworm.
b) the feeding method of the flatworm is an example of extracellular digestion. explain why.
Answer:
a) The flatworm is a predator that feeds on the earthworm, which makes it a consumer in the feeding relationship. The earthworm is the prey, and it is being consumed by the flatworm. The flatworm secretes digestive enzymes into the earthworm, breaking down the earthworm's tissue and absorbing the nutrients.
b) The feeding method of the flatworm is an example of extracellular digestion because the digestive enzymes are secreted outside the flatworm's body, in the earthworm's body. The soluble nutrients resulting from the digestion of the earthworm are then absorbed by the flatworm. In contrast, intracellular digestion occurs when the food is taken into a cell and digested inside the cell. In extracellular digestion, the digestive enzymes are secreted outside the body of the organism, and the nutrients are absorbed into the organism's body.

use this cross section to describe how mount rainier formed
Mount Rainier is a massive stratovolcano located in the Cascade Range in the state of Washington. It is composed of many layers of hardened lava, ash, and rock that erupted from a central vent. Over time, the layers accumulated and compressed under their own weight and the pressure of the surrounding rocks. This process of mountain building, called orogeny, caused the rocks to deform, break and uplift the land to form Mount Rainier. Type of terrain and climate also played a part in its formation. Glaciers and rivers eroded the surrounding land, and elevated the mountaintop by carving deep valleys, creating cirques and arêtes, and reshaping the landscape. Rainier was further enlarged by the eruption of melted glacial ice, ash flows, and lava flows from several small, overlapping volcanoes.

What happens when the number of organisms in an environment is higher than the carrying capacity? A. The population will increase slowly. B. The population remains the same. C. The population will increase quickly. D. The population will decrease.
Answer:
When the number of organisms in an ecosystem exceeds the carrying capacity, the population will decrease.
Please see the explanation!
Explanation:
The maximum that can be maintained forever is the concept of "carrying capacity." This can only be rationally understood as the highest number that can be maintained using exclusively renewable resources. It can only be exceeded by using resources more quickly than they can be replenished.
The population gets wiped out (not by old age mortality) back to the number that can be maintained using only renewable resources when those resources become limited, as they must by definition.
Remember that every population is trying to expand, therefore if a species finds a resource that it can use more quickly than it replenishes, the population will undoubtedly expand to use that newly discovered capability. Another way to put this is to say that when the species average is x newborns and the subsistence supply is steady, (x-2)/x children must perish. Less offspring must perish than the formula predicts when the species finds a new non-renewable source of food, increasing the subsistence supply.
It should be noted that there are plainly too many people in the world. Over the past few hundred years, we have developed various technologies that have increased subsistence extraction and decreased waste. Of course, we have multiplied to occupy that additional space. In order to provide enough food to sustain 7+ billion people at once, we need fossil fuels and a number of other resources that do not replenish as quickly as we use them. The last time humanity were able to maintain their population on exclusively renewable resources, there were less than 1 billion people. Be aware that we have never been able to raise subsistence production as quickly as we have sought to increase our population. We have always had an average of too many infants, as seen by the starvation-related child mortality that affects some populations.
