Why body system is dependent on a constant supply of iron, and what deficiency is caused when this mineral is lacking?
Answer:
For erythropoesis/ RBC production, anaemia
Explanation:
Our body needs a constant supply of blood. The blood contains haemoglobin which is a respiratory pigment and a conjugated protein. It contains iron and globin protein. This iron-containing pigment supplies more oxygen to the tissues and gives red colour to the blood. The deficiency of iron or this haemoglobin pigment in the blood leads to anaemia. The iron pigment or haem pigment of haemoglobin increases the carrying capacity of oxygen. Our body tissue needs oxygen for metabolism.We get iron from foods and these irons play an important role in RBC production in the bone marrow.
As scientists research, they often find information that does not fit with current theories. What happens when new, contradictory information is found?
Final answer:
When scientists encounter evidence that contradicts current theories, they must either revise the theories or develop new ones. This can result in minor adjustments or significant paradigm shifts as seen with quantum mechanics or genetics. Science thus remains a robust, self-correcting mechanism for understanding the natural world.
Explanation:
Science is a continually evolving discipline that thrives on refinement and occasionally requires significant changes to its core theories. When scientists encounter new data that contradicts existing theories, it leads to a process of investigation and assessment. New data might result in the rejection, revision, or development of new theories if they repeatedly disprove or fail to explain certain phenomena or experimental outcomes. Theories must generate testable and falsifiable hypotheses, and when they no longer align with observed evidence, they are subject to change. Planetary formation models provide an example of this, where new discoveries of planetary systems unlike our own prompted revisiting and adjusting the standard models.
When conflicting evidence arises, scientists may engage in a cycle of hypothesis reformulation, experimentation, and debate until a consensus is achieved. In some instances, this can lead to a paradigm shift, a term coined by Thomas Kuhn, signaling a radical overhaul of foundational scientific ideas. Examples of paradigm shifts include the advancement from the indivisible atom concept to the understanding of subatomic particles, or the revisions to Mendel's laws of inheritance with the modern understanding of genetics. However, such shifts happen incrementally as scientists build on existing knowledge.
The scientific method is designed to accommodate new information, maintaining science as a self-correcting pathway to understanding the natural world. Scientists prioritize hypotheses based on their ability to explain data succinctly, predictively, and coherently. It is an ongoing, dynamic conversation between theory and data.
what organisms break down chemical wastes in a treatment plant
Decomposers and recyclers, including bacteria, fungi, and protists, play a key role in breaking down chemical waste in treatment plants. They convert organic matter and pollutants into simpler forms, releasing essential nutrients back into the environment.
Explanation:The organisms that break down chemical wastes in a treatment plant are primarily decomposers and recyclers, such as bacteria, fungi, and protists. These organisms obtain their nutrients from decaying organic matter, using their metabolic activity to release elements like carbon, nitrogen, and phosphorus back into the environment.Fungi, for instance, break down insoluble compounds like cellulose and lignin into absorbable particles, releasing these elements. Similarly, certain bacteria can degrade pollutants like hydrocarbons into smaller subunits or transform them into carbon dioxide. Protists, on the other hand, are often found in anaerobic environments where they contribute to the digestion of cellulose. Collectively, these organisms fulfill an essential role in wastewater treatment, aiding in the bio remediation process.

Explanation:
You need to cut down 3 trees to get to about 5 kilograms of bark. About how many tress do u have to cut down each year to make enough paclitaxel for 60,000 patients?
Final answer:
To produce enough paclitaxel for 60,000 patients, approximately 21,600 trees need to be cut down each year, based on the requirement of 600 g of starting material for a single 300 mg dose of paclitaxel.
Explanation:
To calculate how many trees must be cut down each year to make enough paclitaxel for 60,000 patients, we need to consider the dose required along with the efficiency and starting material for the drug synthesis. Based on the information provided, for a single 300 mg dose of taxol (paclitaxel), 600 g of starting material is needed. If we need to treat 60,000 patients and each patient requires one dose, we need a total of 60,000 × 600 g of starting material.
The total starting material required would be 36,000,000 g or 36,000 kg. Knowing that 3 trees yield approximately 5 kg of bark, we can calculate the number of trees needed as follows:
Number of trees = (Total starting material in kg) / (Bark per 3 trees) × 3 trees
Number of trees = 36,000 kg / 5 kg × 3 trees
Number of trees = (36,000 / 5) × 3
Number of trees = 7,200 × 3
Number of trees = 21,600
Therefore, to produce enough paclitaxel for 60,000 patients, approximately 21,600 trees need to be cut down each year.

What effect does a keystone predator have on its habitat?
a. It increases plant populations.
b. It increases niche diversity.
c. It kills off herbivore populations.
d. It destroys the habitat.
Answer: The correct answer is- b. It increases niche diversity.
A keystone predator is a species, which has profound impact on its ecosystem that is it can control the population and distribution of large number organisms within its habitat.
In other words, its influences the ecosystem as it increases the niche diversity.
For instance, keystone predator such as starfish feeds on the mussel Mytilus californianus and maintains the diversity of species in that communities. As other species will get proper food resources to survive.
Thus, it increases niche diversity.
As we see an increase in habitat alterations, some fish exhibit behavioral adaptations that help with the survival of their young. All BUT ONE is a behavioral adaptation you might see in a freshwater fish species in Georgia. That is:
A) The male and female shiners will swim along the crevice of large rocks and deposit eggs and sperm in the crevice.
B) Male and female catfish exhibit parental care, which includes nest site preparation, fanning of the eggs with their fins, and guarding of the eggs and larvae.
C) The male bluehead chub constructs a gravel mound for spawning. Several other minnow species, known as nest associates, will also use the chub's nest for spawning.
D) Stonerollers are sometimes referred to as creek cows because of their behavior of grazing on algae that helps to transfer large amounts of energy through a food chain.
The correct option is D) Stonerollers are sometimes referred to as creek cows because of their behavior of grazing on algae that helps to transfer large amounts of energy through a food chain.
Stonerollers grazing on algae is a behavior that benefits the ecosystem by controlling algae growth and facilitating energy transfer through the food chain. However, this behavior is not directly related to increasing the survival rate of their young. It is an ecological service rather than a reproductive strategy.
The other incorrect options are
A) The male and female shiners swimming along the crevice of large rocks and depositing eggs and sperm in the crevice is a behavioral adaptation to protect their eggs from predators by hiding them in a secure location.
B) Male and female catfish exhibiting parental care, which includes nest site preparation, fanning of the eggs with their fins, and guarding of the eggs and larvae, is a direct behavioral adaptation to increase the survival rate of their offspring by providing a safe environment and oxygenation for the developing eggs.
C) The male bluehead chub constructing a gravel mound for spawning, which is also used by other minnow species, is a behavioral adaptation that provides a structured environment for the eggs to develop, potentially offering protection and optimal conditions for hatching.

Both aerobic and anaerobic respiration yield a net gain of ATP molecules to be used as energy for living things. The processes of _________ would yield the highest number of ATP.
Aerobic respiration yields the highest number of ATP, up to 38 molecules per glucose molecule. It is more efficient than anaerobic respiration, which only produces 2 ATPs per glucose. Despite being slower, aerobic respiration can sustain energy production for extended periods when fuel is available.
Explanation:The processes of aerobic respiration would yield the highest number of ATP molecules. During aerobic respiration, if oxygen is available, it can yield a significant amount of ATP, approximately 36 to 38 molecules from one glucose molecule. Aerobic respiration is much more efficient in comparison to anaerobic respiration, which includes forms of fermentation where a net of only two ATPs is produced from a glucose molecule. Aerobic respiration takes place in the mitochondria and involves a series of chemical reactions which not only produce ATP but also release carbon dioxide and water as waste products.
It is also important to mention that aerobic respiration is slower but can sustain ATP production for hours as long as fuel is available, whereas anaerobic respiration is much quicker. This is why anaerobic respiration is beneficial for short bursts of energy such as in muscle cells during vigorous exercise when oxygen is limited. Still, due to the higher ATP yield, aerobic respiration is considered the primary method of energy production for aerobic organisms.

why can't we use seawater to irrigate our crops?
Seawater cannot be used to irrigate crops due to its high salt content. Plants are not able to tolerate high levels of salts, which can harm their cells and inhibit essential cellular functions. Freshwater or low-salt water sources are necessary for successful crop irrigation.
Explanation:While some organisms have adapted to survive in highly salty conditions, most plants are not able to tolerate high levels of salts in their environment. The salt in seawater can harm plant cells and block essential cellular functions, leading to plant stress, reduced growth, and crop failure.
In addition, the salt in seawater can build up in the soil over time, making it unsuitable for plant growth. Saltwater irrigation can damage soil structure, decrease soil fertility, and affect the nutrient balance in the soil.
To successfully irrigate crops, freshwater or water with low salt content is needed. Access to safe freshwater sources is crucial for agricultural production and food security, particularly in regions where water scarcity is already a concern.
