Answer:
Facilitate diffusion is the process in which substances are transported across the plasma membrane along the concentration gradient with the help of carrier molecules.
In active transport also carrier proteins are used but they are used to transport the molecules against the concentration gradient.
Carrier proteins bind the molecules to be transported non-covalently and after binding, it undergoes a conformational change which helps in the movement of the molecule through the protein inside the cytoplasm of the cell.
Charged and polar molecules are mainly passed through facilitated diffusion like amino acids, carbohydrates, ions. The rate of transfer of molecules across the plasma membrane is higher in facilitated diffusion than simple diffusion.

describe the modern atomic model of oxygen
Final answer:
The modern atomic model of oxygen incorporates electron configuration, hybridization, and molecular orbital theory to explain the complex bonding and properties of oxygen atoms, highlighting the dynamic nature of electron interactions and molecular structure.
Explanation:
The modern atomic model of oxygen, according to current understanding in Chemistry, is significantly more advanced than the early models of the atom. In this model, oxygen is depicted as having eight protons in the nucleus, surrounded by a cloud of electrons. The electron configuration of oxygen is 1s²2s²2p⁴, which outlines that there are two electrons in both the s orbitals, and four electrons in the p orbitals. However, when oxygen forms covalent compounds, the concept of hybridization comes into play, altering the atomic orbitals into hybrid orbitals that can bond more effectively with other atoms. According to the molecular orbital theory (MO theory), the atomic orbitals of individual oxygen atoms combine to yield molecular orbitals that are delocalized over the entire molecule, such as in O₂. This intricate bonding explains why oxygen has a property called paramagnetism and how electrons are distributed within molecules. Thus, the modern atomic model is characterized by its emphasis on electron energies, probabilities, and molecular interactions, moving beyond static, simplistic representations of atoms to more dynamic and complex ones.

1. How could you test to see if an enzyme was completely saturated during an experiment?
Final answer:
To test if an enzyme is completely saturated during an experiment, the reaction rate is measured at different substrate concentrations. If the reaction rate reaches a maximum and does not increase further even with higher substrate concentrations, it indicates the enzyme is completely saturated with substrate.
Explanation:
The presence of complete saturation of an enzyme during an experiment can be determined through various methods. One common method is to measure the reaction rate (velocity) of the enzyme at different substrate concentrations. As the substrate concentration increases, the reaction rate initially increases. However, at a certain point, further increasing the substrate concentration does not result in an increase in the reaction rate.
When the reaction rate reaches a maximum and does not increase even with higher substrate concentrations, it indicates that the enzyme is completely saturated with substrate. This is referred to as saturation kinetics.
By plotting the reaction rate versus substrate concentration, you can observe the point at which the reaction rate plateaus, indicating enzyme saturation.

Sandra has been having pains just under her diaphragm and a little to the right of the center of her body. They seem to be especially painful after she has eaten fatty food. Which of the following would be best for her to ask her doctor to help her investigate?
If her pancreas is still secreting bileAnswer:
If her small intestine has enough fat-digesting enzymes
Explanation:
The organ which is referred in the question is duodenum of the small intestine. In the duodenum, pancreatic juice containing fat digesting enzyme, lipase is poured. The pancreas releases the pancreatic juice. If lipase, a fat digestion enzyme is not secreted in sufficient amount in the duodenum, the digestion of fats will be hampered which may results in pain below the diaphragm.

How does energy get converted from food molecules to muscles?
Energy conversion from food molecules to muscles involves a process known as cellular respiration. In this process, the energy stored in glucose, obtained from food, is converted into ATP, a high-energy molecule. ATP powers various cellular processes, including muscle contraction.
Explanation:
Energy conversion from food molecules to muscles happens through a biological process known as cellular respiration. When we eat food, our digestive system breaks down the complex nutrients into simpler forms like glucose. This glucose is transported to cells, including muscle cells, through the bloodstream.
In the cells, glucose undergoes a process called cellular respiration, which occurs in the mitochondria. In a three-step process - glycolysis, Krebs cycle, and electron transport chain - the energy stored in glucose is converted into adenosine triphosphate, or ATP. ATP is a high-energy molecule that powers numerous cellular processes, including muscle contraction.
Hence, it’s through this series of reactions in cellular respiration that the energy from food molecules gets converted and used in muscles.

According to the ipat model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish ________.
In the IPAT model, technology that improves our ability to acquire resources like minerals, fossil fuels, timber, and ocean fish generally increases the environmental impact because it boosts our capacity to exploit these resources.
Explanation:According to the IPAT model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish increases the impact on the environment.
The IPAT equation, which stands for Impact equals Population, Affluence, and Technology, suggests that our environmental impact (I) is the product of population size (P), affluence (A), and technology (T).
Thus, technology that enhances resource acquisition typically does so by increasing our capacity to exploit these resources, thereby increasing the environmental impact.

What is a glucose standard curve, and why did you need to obtain one for this experiment? did you correctly predict how you would measure the amount of plasma glucose in a patient sample using the glucosestandard curve?
A glucose standard curve refers to a method used to quantify the amount of glucose in a given sample. In experiments, it's critical in estimating the concentration of glucose through comparative analysis with the standard curve's responses. To measure plasma glucose in a patient sample, you would compare the reactions from the patient's sample with the glucose standard curve.
Explanation:A glucose standard curve is a method used in biological and chemical research, particularly when quantifying the amount of glucose in a sample such as plasma. It's essentially a graph that depicts the response received from the glucose test (like color change) as a function of known glucose concentrations. The plot provides a reference to assess glucose levels in unknown samples.
In an experiment, obtaining a glucose standard curve is crucial for extrapolating the concentration of glucose in a patient's plasma sample. This is achieved by comparing the test results from the unknown sample to the standard curve. The level of color change (caused by glucose's reaction with certain chemicals) in the patient's sample, compared to those in the standard curve, will suggest a corresponding concentration of glucose.
Yes, you predicted correctly. To measure plasma glucose in a patient sample, you would use the responses from the patient's sample and compare them with the glucose standard curve. This method allows for an accurate estimation of glucose concentrations, offering valuable information for diagnostic purposes.

Explain how poaching can lead to over utilization of species
As we know that poaching is an illegal hunting or killing of animals. There are many countries where animals are poached. Poaching of animals happened due to many reasons. Like for an ivory, elephants are poached.
People who poached animals, do not care for them, they just kill or hunt animals for their own benefits. Some people have demand for ivory and some people poached elephants to get ivory. This could lead to over-utilization of animals.
Moth populations changed from mostly light colored to mostly dark colored in the 1800s. this relates to _____. answers
The correct answer to this is:
“Microevolution”
Microevolution is an evolutionary change that occurs to small group of species within a short span of time. The cause of this occurrences are most commonly an external factor. For the case of moth, the soot produced by the Industrial Revolution in the 1800s resulted in trees to darken and other places in England where moths liked to perch. Because of this, light colored moths were more easily identified by predators against a dark background. Dark colored moths had a larger survival advantage since they could blend in against a similarly dark background. Natural selection or microevolution favoured the darker moths, therefore their proportion within the moth population increased.
Microevolution is the right answer.
Microevolution is the development in allele regularities that befalls over time within a culture. This variation is due to four distinct methods: mutation, adaptation (artificial and natural), gene flow and hereditary drift. This development occurs over a comparatively short span of time than the development takes place under the term macroevolution that is where greater diversity in the community befalls.
