Compare and contrast the observed color of plums (purple) and spinach leaves (green) with the absorbance spectra featured in one of the video clips that support this lab topic. Use your understanding of observed color to explain why an extract made from plums absorbs light between 500 nm and 600 nm, whereas an extract made from spinach leaves (like the one you analyzed in this lab topic) absorbs light at much shorter wavelengths.

Answers

Answer 1

Answer:

Plums have high concentrations of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

Spinach leaves have a high concentration of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

Explanation:

White light is a mixture of the visible spectrum of light. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.

The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.

The green color is normal in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. Blue wavelengths a between 420-470 nm. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

On the other hand, many fruits -blueberries, cherries, plums, or grapes- and flowers express a high concentration of anthocyanin, a pigment that reflects spectrums of red, blue, and purple wavelengths. This pigment absorbs light of 250, 370, and 500-600 nm. Yellow and orange wavelengths correspond to 500-600 nm.

Plums:

Pigment → anthocyaninAbsorbs → light between 500 nm and 600 nm → yellow-orangeReflects → light between 300 nm and 370 nm → blue-purpleColor detection → purple

Spinach leaves:

Pigment → chlorophyllsAbsorbs → light between 420-470 nm → blueReflects → light between 470-530 nm aprox. → greenColor detection → green

Answer 2

(a) Plums have high engagements of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

(b) Spinach leaves have a high engagement of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

What is the reason that plums absorb light between 500 nm and 600 nm?

White light is a mixture of the visible spectrum of light. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected.

A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I?
a. Ubiquinone
b. Complex II
c. Complex III
d. Complex IV

Answers

Answer:

b. Complex II

Explanation:

The electron transport chain is a sequential series of proteins located in the inner membrane of the mitochondria that act to transfer electrons from different members of the transport chain in a series of redox reactions, which is coupled to the movement of protons (H+) across the membrane. Complex I (also called NADH dehydrogenase or NADH- CoQ reductase) accepts electrons from NADH and passes them to Complex III (also known as coenzyme Q reductase), which also receives electrons from Complex II (succinate coenzyme Q reductase). Ubiquinone (Coenzyme Q) accepts electrons from both complex I and complex II and transfer them to complex III. From complex III electrons pass to complex IV through cytochrome c oxidase and finally to molecular oxygen (O2, the final electron acceptor). In consequence, Complex I and Complex II are linked by different pathways to Complex III, thereby it is expected that Complex II remains unaffected by a mutation in Complex I.

A red blood cell leaving the left ventricle of the heart would take which pathway to reach the facial artery?

Answers

Answer:

Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.

Explanation:

hope this helps

The pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery

The arch of the aorta can be considered as the peak of the ascending aorta.

The brachiocephalic trunk refers to the second branch to arise from the aorta.

The right common carotid artery arises as a branch of the brachiocephalic trunk of the aortic arch.

The facial artery is a branch of the external carotid artery that supplies blood to the muscles and skin of the face.

In conclusion, the pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery.

Answers

answer: there is a 50% probability of the 2nd child having albinism.

since the mother and father are both carriers then they would both have Aa. meaning there would be a 50% chance of the child being normal (AA) and a 50% chance of the child having albinism (aa)

Both the mother and father would have Aa because they are both carriers. i.e., there would be a 50% probability that the child would be albinized (AA) and a 50% chance that the child would be normal (aa).

What is albinism?

Albinism refers to a collection of extremely uncommon genetic illnesses that are characterized by the absence of melanin at birth in either an animal or a plant.

People who have albinism either have a significantly diminished amount of melanin or none at all. Both their coloring and their eyesight may be impacted as a result of this. Albinism is characterized by extremely light or very light blonde hair, while some individuals with the condition have brown or ginger hair. The precise color is determined by the amount of melanin that is produced by the body.

An Overview of Geothermal Pros and Cons:

Pros Cons

This energy source is more environmentally friendly than conventional fuel sources.  The largest single disadvantage of geothermal energy is that it is location specific.

A source of renewable energy.  Gases are released into the atmosphere during digging.

The number of exploitable geothermal resources will increase with ongoing research and development in the industry.  Geothermal energy runs the risk of triggering earthquakes.

A sustainable source of energy as its always available unlike wind and solar.  Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.

A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy.  Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.

No fuel is required.  

Increase in exploration meaning that new technologies are being created to improve the energy process.  

Pollution levels are much lower compared to fossil fuels.

Answers

Answer:

- Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.

- Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.

- Consumers create an additional energy transfer when they utilize these sugars or eat each other.

- As in other ecosystem organisms in hydrothermal vent communities also transforms chemical energy into other forms such as kinetic energy (energy of motion).

Explanation:

A hydrothermal vent is a geyser on the seafloor that is generated by underwater volcanoes or tectonic activity through which geothermally heated water erupts. Hydrothermal vent ecosystems contain hydrothermal microorganisms which are able to survive just outside the hottest waters. For example, Methanopyrus kandleri are hyperthermophile prokaryotic microorganisms that live in these ecosystems where they produce methane from reducing CO2. Chemosynthesizers are able to convert carbon molecules (e.g., CO2) and nutrients into organic matter by the oxidation of inorganic compounds such as hydrogen sulfide and/or ferrous ions. Moreover, hydrothermal vent ecosystems have the potential to support high biomass and productivity levels due to the establishment of symbiotic relationships between chemosynthesizers with respiring heterotrophs, which obtain energy from other organisms. Chemosynthesizers are eaten by other organisms (e.g., amphipods and copepods), whereas larger organisms (e.g., snails and crabs) form predator and prey relationships above these primary consumers.

Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.

Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.
