The cell membrane (plasma membrane) is describe as a highly selective
barrier composed of alipid bi-layer. This structure plays an important role
in moving molecules across the cell membrane in order for the cell to
maintain homeostasis. If the cell is unable to take in the materials it needs
or remove vwhat it does not need, the cell may die. This inability of cells to
maintain homeostasis may cause sickness or even death of an organism.
Why is it important that the cell membrane is highly selective?
O So that the cell wall is stabilized and maintains its rigidity.
O To prevent certain ions and molecules from entering or exiting the celI.
O So that proteins and lipids can attach to the membrane where needed.
O To allow movement of materials in and out of the cel.
Answer:
O To prevent certain ions and molecules from entering or exiting the celI.
Explanation:
The cell needs to keep a constant chemical composition on the inside in order to mantain homeostasis

Which of the features of this carbon-based macromolecule can be used to distinguish it from the other biological molecules?
Answer:
there are four major classes of biological macromolecules: 1. Proteins (polymers of amino acids) 2. Carbohydrates (polymers of sugars) 3. Lipids (polymers of lipid monomers) 4. Nucleic acids (DNA and RNA; polymers of nucleotides) Let’s take a closer look at the differences between the difference classes. Now that we’ve discussed the four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids).

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.

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.

According to the author, what is the main reason for the decrease in trillium in the forest? What evidence does she give to support her claim?
Answer:
The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard and trillium. One was left open to deer, and the other was fenced off. Scientists kept track of the fields for several years. They found that trillium was able to regain much of its original space in the protected field. In the unprotected field, there was still more garlic mustard because the deer ate the trillium. The author also states that similar research studies have been conducted in many forests across the United States, and they all reveal similar results.
