Explanation:
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?
Answers
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.

Two colleagues that share the same office are exposed to the flu virus one week in January. Janet just recovered from the same flu virus two weeks earlier, while Mark has not been sick yet this winter. Which person do you expect would be more likely to become sick with this flu virus and why?
Janet: since she already had the flu, her immune system is weaker than Marks.
Janet: she will most likely get the flu again, and a more severe case of it.
Mark: he has not acquired any active immunity to the flu, and Janet has.
Mark: he has only passive immunity to the flu which will not benefit him in this case.
Answers
I believe Mark is more likely to get sick with the flu virus because Janet has acquired a slight immunity because she was infected with it while Mark has not been infected with the virus

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
Answers
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.

In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester
Answers
Answer:
In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.
The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.

polar
non-polar
Answers
Answer:
The nature of the indicated covalent bond is polar.
Explanation:
The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.
In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.
CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.
The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function ?
Answers
Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
Oligosaccharides are a type of carbohydrates that contain the combination of a few monosaccharides. The are also found as part of the components of the membrane.
If an animal cell lacks this type of carbohydrates (oligosaccharides), the function impaired would be the cell-cell communication function.
Oligosaccharides performs various functions as part of the component of the plasma membrane. It functions in cell to cell recognition and binding and communication. They usually contain 3-10 sugar units (monosaccharides).Learn more: https://brainly.com/question/22301340
