The electron transporter chain is the sequence of redox reactions that occur in the mitochondrial membrane as electrons flow through different electron transporters resulting in energy production. In the attached files you will find the image with the colored structures.
What is the electron transporter chain and how does cyanid inhibit it?
The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane. It constitutes a series of enzymatic reactions to release and save energy for the organism’s correct functioning.
Along the chain, there are four proteinic complexes in the membrane that contain the electron transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
Different redox reactions occur to pass electrons from NADH along the chain.
Released energy creates a proton concentration gradient used to synthesize ATP.
Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport, which ends in producing energy. It is the complex IV.
Ion cyanide is a powerful cellular poison that inhibits cellular respiration by binding to the ferric ion of cytochrome oxidase.
Cyanide-ferric binding inactivates the enzyme and blocks electron transference. The chain is interrupted, leading to no oxygen consumption and no ATP production.
Since muscles do not get to have ATP as a source of energy, they weaken.
The interruption of the electron transporter chain produces an anaerobic state that could be culminating.
In the attached files you will find the image with the colored structures. Complex IV is the one affected by cyanide.

A student astronomer went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get smaller over time. Why did this happen?
Answer:
The light part of the Moon appeared to get smaller over time because of the change in the relative position of the Moon, the Sun, and the Earth. This is known as the lunar phase. The changing appearance of the Moon from the Earth's perspective is caused by the Moon's orbit around the Earth and the position of the Moon and Sun relative to the Earth. The Moon's phases are caused by the angle between the Moon, Earth, and Sun changing, as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, the side facing the Earth is not illuminated by sunlight, so it appears dark, and this is called a new moon. When the Moon is on the opposite side of the Earth from the Sun, the entire side of the Moon facing the Earth is illuminated by sunlight, so it appears full, and this is called a full moon. As the Moon moves in its orbit, the angle between the Sun, Earth, and Moon changes, causing the illuminated portion of the Moon visible from the Earth to change, leading to different lunar phases.

With your group members discuss and answer the following questions.
1. What does only 1 circle around the seismic station tell you about the epicenter?
2. How does having information from 2 seismic stations help determine where the epicenter of the EQ is?
3. Why does having information from 3 seismic stations help determine the location of the epicenter?
4. What data is provided for you by a seismogram?
5. Why does the S and P interval (time difference) increase the further away you get from an EQ's epicenter?
6. According to the seismogram, which body wave produced the most amount of ground shaking? Support your answer.
1) One seismogram represents the distance to the epicenter (indicated by one circle). This is determined by the arrival times of the P and S waves. When the seismograph is near to a quake, the S-waves arrive shortly after the P-waves.
2) A single or double recording station could only measure distance, not direction; a full circle is drawn around the station to allow for all possibilities.
3) Triangulation is a technique used by scientists to determine the location of an earthquake's epicenter. When seismic data is collected from at least three different locations, the epicenter may be established by where the data links. A network of seismographs positioned in various directions records every earthquake.
4) A seismograph is a device used to record seismic waves caused by an earthquake, explosion, or another Earth-shaking event.
5) In the aftermath of an earthquake, the P waves go ahead of the S waves. As a result, the longer the time difference between the arrival of the P and S waves, the greater the distance between a seismic recording station and the earthquake epicenter.
6) Surface waves frequently induce more ground motion than body waves and hence cause more harm.
What exactly is a seismograph?Seismometers are measuring instruments that detect ground noises and vibrations caused by earthquakes, volcanic eruptions, and explosions. Seismographs usually consist of a seismograph, a timing device, and a recording device.
Modern seismometers are capable of detecting ground movements as small as a few nanometres - a millionth of a millimeter. The magnitude of the earthquake is calculated using the measured amplitudes and its closeness to the hypocenter.

Carlton and Vanessa are lab partners in their biology class. One of their labs was to run the smell test experiment on each other.
When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also
the various intensities of evergreen. Although Carlton could distinguish what the vanilla and evergreen smells were, he couldn't tell
there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

d) What happens to a microscope if place at the edge?
When the object is placed on the slide and is in focus for each objective, the space between the slide and the objective lens gets reduce, so the microscope shouldn't be set exact at the edge.
As the objective magnification increases, the working space also increases. Therefore, you need to change it to a higher power target.
Change the focus knob to increase the stage as you look at the objective lens and stage from the side. Without permitting the objective to make contact with the coverslip, increase it as high as it can go. The sample's focus or the condenser and light intensity might need to be arranged.
Thus the accurate way to focus is that adjustments need to be made effectively and smoothly

If 27,500 Kj is at the producer level how many Kj are available for the secondary
consumers ?
By being consumed by another organism, organic molecules from one organism's body can transfer energy from one trophic level to the next. But typically, there is not a particularly effective way to move energy between trophic levels.
The energy stored as biomass at one trophic level, such as primary producers, only accounts for 10% of the energy stored in the following trophic level (e.g., primary consumers).
In other terms, as trophic levels rise, net production falls by a factor of 10.
First-level trophic level members are producers. In the second trophic level, there are primary consumers. The third trophic level has secondary consumers. Because they are at a low trophic level than Tertiary Consumers, Secondary Consumers receive more energy.Since 27,500 Kj energy is present at the producer level, 10% of it will be available at the primary consumer level. This accounts for 2750 Kj of energy.Now, 10% of 2750 Kj of energy will be available at the secondary consumer level. This is equivalent to 275 Kj of energy.Learn more about trophic levels here:

1. Angelman syndrome and Prader-Willi syndrome are used as examples of epigenetic inheritance.
a. Explain the symptoms and effects of each of these diseases.
Angelman syndrome is characterized by intellectual disability, severe speech impairment, ataxia, seizures, and a happy demeanor. Prader-Willi syndrome involves hypotonia, hyperphagia, obesity, intellectual disability, behavioral problems, and short stature.
Angelman syndrome and Prader-Willi syndrome are two distinct genetic disorders that are often discussed in the context of epigenetic inheritance. Both conditions result from abnormalities in a specific region of chromosome 15, but they have opposite effects due to differential genetic imprinting.
Angelman syndrome is characterized by developmental delays, severe intellectual disabilities, speech impairments, and motor coordination problems.
Individuals with Angelman syndrome often exhibit a happy and excitable demeanor, with frequent episodes of laughter and a fascination with water. They may also experience sleep disturbances, seizures, and a lack of speech development.
On the other hand, Prader-Willi syndrome manifests with distinct symptoms such as hypotonia (poor muscle tone) during infancy, hyperphagia (insatiable appetite) leading to obesity, developmental delays, learning difficulties, and behavioral challenges.
Individuals with Prader-Willi syndrome often have a compulsive need for food and struggle with weight management. They may also experience hormonal imbalances, growth hormone deficiency, and behavioral issues such as temper tantrums and obsessive-compulsive behaviors.
Epigenetic inheritance refers to the transmission of information from one generation to another that affects gene expression without altering the underlying DNA sequence.
In the case of Angelman and Prader-Willi syndromes, these conditions result from epigenetic changes, specifically imprinting, in the chromosomal region involved. Imprinting refers to the process by which certain genes are marked or silenced based on their parental origin.
In Angelman syndrome, the paternal copy of the UBE3A gene is deleted or silenced, leading to a lack of functional UBE3A protein in the brain. In Prader-Willi syndrome, the maternal copy of the same gene is affected. These imprinted genes play critical roles in brain development and function, leading to the distinct symptoms observed in each disorder.
It is important to note that while both Angelman and Prader-Willi syndromes are considered examples of epigenetic inheritance, the underlying mechanisms and specific epigenetic changes involved are complex and continue to be studied.
