Answer: The phosphate portions attract water, and the lipid portions repel water.
Explanation:
Lipids are hydrophobic, while phosphates are hydrophilic. The lipid tails of phospholipids repel water and attract other lipid tails, so they are always on the inside of the bilayer, keeping them away from the water. The phosphate portions attract water, so they face the outside of the bilayer.
Phospholipids form a bilayer in water because the phosphate portions attract water, and the lipid portions repel water. Thus, the correct option for this question is C.
What is Phospholipid?Phospholipid may be defined as an amphipathic molecule that is significantly constructed from four components. They are:
Fatty acids.A phosphate.Alcohol is attached to the phosphate.A platform to which the fatty acids are attached.The platform on which phospholipids are built may be glycerol or sphingosine. A phospholipid is typically constructed of phosphate and lipids groups.
Among which phosphate portion is hydrophilic which attracts water molecules, while lipid portions are typically hydrophobic that repel water molecules. The lipids molecules are generally insoluble in water while soluble in organic solvents like chloroform, benzene, etc.
Therefore, due to the structural and functional differences phospholipids form a bilayer in water. Thus, the correct option for this question is C.

Light-dependent reactions
Light-independent reactions
Sun's energy absorbed
Sugars produced
Answer:
The question is unclear but I suppose we're to match the stage of photosynthesis with it's description below.
Light-dependent reactions- Sun's energy absorbed
Light-independent reactions- Sugars produced
Explanation:
Photosynthetic process involves two main stages viz: light dependent stage and light-independent stage. In the light dependent stage, light energy from the sun is trapped or absorbed by the Chlorophyll pigment of green leaves. The absorbed energy is used to split water in a process called PHOTOLYSIS OF WATER.
This process (photolysis) releases protons that build up in the thylakoid membrane to produce a proton pump that generates ATP. At the end of the light dependent reactions, ATP and NADPH molecules are produced.
In the light independent stage which occurs in the stroma of the CHLOROPLAST, the ATP and NADPH molecules produced in the light stage are used to power and reduce carbondioxide (CO2) to synthesize sugar (glucose).

Scientists often ask questions to clarify data or guide scientific research. What are two scientific questions you have that
could clarify relationships about the DNA or traits of these orchids?
Answer:What traits would orchids have if the MADS-box genes were not duplicated?
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?
Explanation: The example given by Plato
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
What is Genetic mutations?The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.
For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.
The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.
Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

If the number of photosynthetic organisms on Earth decreased drastically, which would happen as a result? Less water would be available on Earth’s surface. Less solar energy would reach Earth’s atmosphere. More oxygen gas would be found in Earth’s atmosphere. More carbon dioxide gas would be found in Earth’s atmosphere.
If photosynthetic organisms are decreasing on Earth there is no consumption of carbon dioxide, hence option 4 is correct.
How much carbon dioxide Earth’s atmosphere?The amount of oxygen in the atmosphere will likewise decrease as the number of photosynthetic species rises.
More carbon dioxide gas would be found in the atmosphere because forests, especially rainforests, create more oxygen. The development of oxygenic photosynthesis was the most significant metabolic advancement in Earth's history.
It liberated life from the finite supply of reductants drawn from geochemistry and allowed it to create energy and reduce power directly from sunshine and water.
Therefore a decrease in photosynthetic organisms increases the carbon dioxide gas in Earth’s atmosphere.

In an electron microscope, the sample is bombarded with a stream of electrons that are expelled from an electron gun. The electrons interact with the sample component, the result of which is transformed into an image. Why do you think electron microscopes allow for greater magnification than compound microscopes?
Answer:
It is because the electron microscope uses a shorter wavelength electron
Explanation:
In an electron microscope the sample is always bombarded with a stream of electrons. These electrons usually have shorter wavelengths.
The electrons interact with the sample component well, the result of which is transformed into an image which is always clearer and allows for greater magnification than the compound microscope as a result of the short wavelength electrons being used.
Answer:
Due to the shortened wavelength electron it causes a greater magnification than compund microscopes.

If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result? Less water would be available on the earth’s surface. Less solar energy would reach the earth’s atmosphere. More oxygen gas would be found in the atmosphere. More carbon dioxide gas would be found in the atmosphere.
Answer:
More carbon dioxide gas would be found in the atmosphere.
Explanation:
Photosynthetic organisms convert carbon dioxide in air to oxygen through photosynthesis, while other non-photosynthetic organisms only consume oxygen and release carbon dioxide through respiration, they do not undergo photosynthesis.
When the number of photosynthetic organisms on the earth decreased drastically, the carbon dioxide released from other non-photosynthetic organisms cannot be converted to oxygen, so carbon dioxide in air accumulates.
Read the passage from Darwin's journal. These two species of Amblyrhynchus agree, as I have already stated, in their general structure, and in many of their habits. Neither have that rapid movement so characteristic of the genera Lacerta and Iguana. They are both herbivorous; although, the kind of vegetation on which they feed is so very different. Mr. Bell has given the name to the genus from the shortness of the snout; indeed, the form of the mouth may almost be compared to that of the tortoise: one is led to suppose that this is an adaptation to their herbivorous appetites. It is very interesting thus to find a well-characterized genus, having its marine and terrestrial species, belonging to so confined a portion of the world. The aquatic species is by far the most remarkable because it is the only existing lizard which lives on marine vegetable productions. As I at first observed, these islands are not so remarkable for the number of the species of reptiles; as for that of the individuals, when we remember the well-beaten paths made by the thousands of huge tortoises—the many turtles—the great warrens of the terrestrial Amblyrhynchus—and the groups of the marine species basking on the coast-rocks of every island—we must admit that there is no other quarter of the world where this order replaces the herbivorous mammalia in so extraordinary a manner. What differences did Darwin find about the two species? One is fast, while the other is slow. One eats plants, while the other eats meat. One lives inland, while the other lives in the water. One has a long snout, while the other has a short snout.
Answer:
One lives inland, while the other lives in the water.
Explanation:
Amblyrhynchus cristatus is a marine reptile that lives in the Galápagos Islands. This species attracted the attention of Darwin because it is a marine iguana that lives exclusively in the Galapagos and, interestingly, their close relatives inhabit in land, also in the Galápagos Islands. The marine and land iguanas from Galápagos form a phylogenetic clade that is characterized by high diversification levels, which are evidenced by conspicuous phenotypic differences. These species can hybridize with each other, but the offspring are infertile. Recently, it has been shown by using phylogeographic analysis that both species diverged 8-10 million years ago.
Answer:
They both eat plants.
Explanation:
They are both herbivorous; although, the kind of vegetation on which they feed is so very different.

In an organ transplant, a doctor transfers a donated organ from a recently deceased person to a live patient. One of the consequences is that the patient’s immune system—the system that protects against diseases and pathogens in the body—will reject the new organ. Explain why this consequence isn’t a concern with organs grown from human stem cells.
The immune response is usually triggered by the presence of the donor's own unique set of HLA proteins, which the recipient's immune system will identify as foreign.
What is graft rejection?To prevent infection, the immune system launches an attack against foreign invaders when it comes into contact with them. The immune system must be able to distinguish between our own healthy tissues and external invaders in order to avert an attack on our own cells and tissues (autoimmunity).
When the recipient's immune system assaults the donor graft and starts killing the transplanted tissue or organ, graft rejection takes place. The presence of the donor's own distinct collection of HLA proteins, which the recipient's immune system will recognize as alien, typically initiates an immunological response.
Histocompatibility refers to the degree of resemblance among the HLA genes of the donor and recipient; the more suitable the donor and recipient are genetical, the more accepting the recipient's immune system should be of the transplant. There will always be some degree of rejection, though, unless the donor and receiver are genetically identical (such as identical twins).
Therefore, the difference in HLA proteins results in graft rejection.

resources as an average American, what percent of
the Earth would need to be used to support
everyone?
A. 150%
B. 75%
C. 200%
D. 50%
Answer:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
Sowe actually would need like 5 Earths.
So none of the options is matches this, but this may be because this question is about some specific resources and not for the specific energy used. The closest option is 200%
