Why do the different genetic types of albinism result in a similar phenotype?
Answer:
Why are there different variations of albinism and why it results in the same basic phenotype?
The phenotypic heterogeneity of albinism is due to the different gene mutations affecting various points along the melanin pathway, resulting in varying degrees of decreased melanin production. Additionally, associated developmental changes occur in the optic system as a result from this hypopigmentation.

Cytochrome C is a protein that functions in cellular respiration as part of the electron transport chain. It is frequently used to determine evolutionary relationships between different organisms because it is highly conserved (only differs slightly) between different organisms. A student researching evolutionary relationships between different organisms came across the following information about the differences between cytochrome C proteins in different organisms when compared to humans. Number of different amino acids compared to humansChimpanzee0Rhesus Monkey1Cow10Yeast42 The student plans to use an antibody to the human cytochrome C protein in an ELISA test on cytochrome C samples from these four organisms. What should she use as a positive control
Answer:
Human cytochrome C
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is a technique widely used to detect and measure antibodies and antigens in biological samples. This technique can be used to diagnose different diseases by detecting antigens that bind to antibodies. The ELISA test consists of a plate with a capture antibody against the antigen of interest coating the plate. Subsequently, the target antigen is detected by adding a detection antibody labeled with an enzyme (e.g., alkaline phosphatase) that binds to this antigen. Finally, a particular substrate (e.g. ABTS) is added to the plate and the subsequent reaction converts it into a colored product which can be easily detected using microplate readers. In this case, the positive control will be human cytochrome C which will bind to specific antigens in order to evidence the presence of this molecule in the sample.

For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. 4 1 5 0 2
Answer:
For each glucose that enters glycolysis, 2 acetyl CoA enter the citric acid cycle.
Explanation:
SYNTHESIS OF 2Acetyl CoA -:
The glucose is transformed into 2pyruvate (6 carbon molecules are converted into 2 -3 carbon molecules) during glycolysis. In both aerobic and anaerobic respiration, glycolysis occurs frequently. This process takes place in the cytoplasm (it does not require oxygen or mitochondria), but if both oxygen and mitochondria are present, two molecules of pyruvate join mitochondria and prepare for citric acid cycle.
Until entering this, the molecules go through a mechanism known as the linked (connects glycolysis with citric acid cycle) reaction, in which the pyruvate molecule is transformed into 2 acetyl CoA (meaning 3 carbon molecules are converted into 2 carbon molecules) and a carbon molecule is released in the form of [tex]2CO_2[/tex] (waste product).
2NAD+ and NADH are synthesized in the linked reaction, implying that reducing power is produced. It means that electrons from pyruvate are released in the form of hydrogen, which 2NAD+ accepts and reduces to form 2 NADH.
[tex]Glucose[/tex] → [tex]2pyruvate[/tex] → [tex]2Acetyl CoA[/tex]
Linked reaction is also known as oxidative -dicarboxylation.
Hence, 2 Acetyl CoA is required to enter citric acid cycle.
1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO2 and water. Like oil spills cause damage
to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
a) How are aquatic organisms affected by oil spills in the ocean?
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
c) Name any two species of microbes which can degrade rubber from
garbage.

Seismographs rely heavily on a pendulum (free-swinging weight) to record measurements. How do you think using a pendulum helps detect small earthquakes?
Answer:
Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.
Principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement. The energy from any seismic activity excites this “proof mass” as it is called by geophysicists, making it vibrate. When they detect movement, such as the shifting plates of an earthquake, a pendulum with a pen attached to it graphs the magnitude of the movement. If the pendulum swings vigorously, scientists know that the seismic waves are intense and potentially dangerous. My guess is, when pendulum swings lightly it determines mild intensity and small impact of an earthquake.

Question 5
Some human cells can perform anaerobic respiration for limited amounts of time, such as during periods of heavy exercise. Use the results of your experiment to explain how anaerobic respiration could benefit human survival.
Answer:
My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.
Explanation: from plato, so change it a bit.

What is anaerobic respiration ?Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.
