Phycobiliproteins are complex proteins in cyanobacteria that absorb light energy. There are three kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin—responsible for capturing green light, phycocyanin—responsible for capturing orange-red light, and allophycocyanin—responsible for capturing red light.
Since light can only penetrate to certain depths in oceans (figure 1), phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll. (4 points)
A. Explain the relationship between chlorophyll absorption and wavelength.
B. In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best justifies the claim that this species is better adapted to environmental changes than the cyanobacteria described above?
Answer:
Part A:
— Chlorophyll absorbs different wavelengths than chlorophyll does.
— Chlorophyll does not absorb wavelengths that are green and yellow, which is indicated by a very low degree of the light absorption.
Part B:
Photosynthetic Organisms are organisms capable of photosynthesis. Photosynthesis is greenery and other organisms using the energy from sunlight to synthesize foods from carbon dioxide and water. Leaving allophycocyanin to be the protein these plants and other organisms receive from the light. So for the process, in order for the plants to live they must be able to go through photosynthesis giving the plants the energy and proteins they need to produce food and to release oxygen into the environment.
Answer:
The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose wavelength is between about 400 nm and 700 nm.
Visible light from the sun appears white, but it’s actually made up of multiple wavelengths (colors) of light. You can see these different colors when white light passes through a prism: because the different wavelengths of light are bent at different angles as they pass through the prism, they spread out and form what we see as a rainbow. Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.
Photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others.
The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.
Although both chlorophyll a and chlorophyll b absorb light, chlorophyll a plays a unique and crucial role in converting light energy to chemical energy (as you can explore in the light-dependent reactions article).
All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria Because of the central role of chlorophyll a in photosynthesis, all pigments used in addition to chlorophyll a are known as accessory pigments—including other chlorophylls, as well as other classes of pigments like the carotenoids. The use of accessory pigments allows a broader range of wavelengths to be absorbed, and thus, more energy to be captured from sunlight.

Red-shift
Emission spectra
Light from a star does not contain all the wavelengths of the electromagnetic spectrum. Elements in the star absorb some of the emitted wavelengths, so dark lines are present when the spectrum is analysed. Different elements produce different patterns of dark lines. The diagram shows part of the emission spectrum of light from the Sun.
A gradient colour spectrum of the sun.
Spectra from distant galaxies
Astronomers can observe light from distant galaxies. When they do this, they see it is different to the light from the Sun. The dark lines in the spectra from distant galaxies show an increase in wavelength. The lines are moved or shifted towards the red end of the spectrum. This effect is called red-shift. The diagram shows part of the emission spectrum of light from a distant galaxy.
A gradient colour spectrum of a distant star.
Red-shift and speed
Astronomers see red-shift in virtually all galaxies. It is a result of the space between the Earth and the galaxies expanding. This expansion stretches out the light waves during their journey to us, shifting them towards the red end of the spectrum. The more red-shifted the light from a galaxy is, the faster the galaxy is moving away from Earth

Imagine an animal cell lost half of its mitochondria. Explain how the cell would be different.
YOU WILL GET 100 POINTS.
Answer:
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...
Explanation:
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.
in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

XX=Female XY=Male.
your best friend has five children and they are all boys. They are expecting their 6th child. What would be the probability for their 6th child to be a girl? Why
Answer:
50% or 1/2
Explanation:
The probability of their 6th child being a girl would be 50% or 1/2.
During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.
XX x XY
XX (female) XY (male) XX (female) XY (male)
XX - 1/2 or 50%
XY - 1/2 or 50%
Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.
How does the nitrogen cycle control the quality of water within a aquarium and what could cause an imbalance (build of toxic chemicals such as ammonium).
Answer:
Explanation:
Ammonia is removed from an aquarium system through the use of a biofilter. The biofilter provides a substrate on which nitrifying bacteria grow. These nitrifying bacteria consume ammonia and produce nitrite, which is also toxic to fish. Other nitrifying bacteria in the biofilter consume nitrite and produce nitrate.

The difference between PCR and real-time PCR is thatA. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.B. real-time PCR can amplify DNA a billion-fold within just a few hours, while standard PCR cannot.C. real-time PCR can determine the DNA sequence, while standard PCR cannot.D. real-time PCR uses DNA polymerase, while standard PCR does not.
Answer:
The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.
Explanation:
PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.
