move through the lipid bilayer of the cell membrane? *
O They are hydrophobic.
O They are ions.
O They are small, non-polar.
They are polar
Answer:
Explanation:
Option A they are hydrophobic is the correct answer
These molecules move across the lipid membrane because they are hydrophobic. So the correct option is A.
What is hydrophobic?In both the home and industrial realms, several hydrophobic materials may be discovered. The vast majority of organic molecules, alkanes, oils, fats, and greasy substances are hydrophobic by nature.
Hydrophobic chemicals are used in a variety of processes, such as the chemical separation of polar elements from non-polar ones, the cleanup of oil spills, and the removal of oil from aqueous solutions. It is a well-known fact that when oil or fats are combined with water, two different layers are created that are inimical to one another since water is polar, but fats and grease are non-polar and especially hydrophobic.
Animals and plants both exhibit hydrophobicity as examples. There are hydrophobic coats on the surface of the leaves since many plants are hydrophobic in nature. The coating's main duty is to prevent water and rain from adhering to the leaves, which often stops the flow of nutrients.
The movement of water from roots to leaves determines how quickly nitrites move through plants. Therefore, if the leaf surfaces lack hydrophobicity, the osmosis process and osmotic pressure will be disrupted, which will have a significant impact on how well plants are nourished.
Therefore the correct option is A.

Why is "dysfunction of the brain" so hard to wrap your head around? How is it different
from, say "dysfunction of the pancreas"?
Answer: I would say it's because there is so much about the brain that we don't know about yet, it's harder for us to understand certain illnesses and dysfunctions because of the sheer complexity of the organ and the role it plays in our own existence. It's easier to understand an organ such as the pancreas because while both fragile and complex, it is not nearly as mysterious as the human brain and doesn't have even nearly the same range of function.

Geologists mapped the ocean floor and discovered the mid-oceanic ridge.D. Divergent boundaries in the ocean create a chain reaction that pulls plates apart on land
The geologists mapped the ocean floor and discovered the mid-oceanic ridge. The correct option is C.
What is crustal movement?The movement of the plates that make up the Earth's crust is referred to as tectonic shift. The Earth is comprised of a many major plates and several minor plates.
The Earth is constantly undergoing change. The Earth's crust, known as the lithosphere, is made up of 15 to 20 moving tectonic plates.
Very active crustal movements in subduction zones, characterized by uplift and erosion in island arcs and subsidence and sedimentation in ocean trenches, continue indefinitely.
The upward movement of hot rocks from deeper parts of the Earth's crust is unavoidable due to uplift and erosion of the Earth's crust.
Geologists discovered the mid-oceanic ridge after mapping the ocean floor.
Crustal movements generate boundaries that are convergent, divergent, and transformative.
Thus, the correct option is C.

The sodium-potassium ion pump simultaneously transports two different solutes. Is the sodium-potassium ion pump an example of a cotransporter? Justify your answer by explaining the mechanism of the pump.
SERIOUS ANSWERS PLEASE. GOD BLESS
Answer:
The sodium-potassium ion pump does not simultaneously transport sodium and potassium molecules, but alternatively, it is a primary active transport and not a co-transport.
Explanation:
The sodium-potassium ATP-ase pump is considered an active transport mechanism, in charge of transporting sodium (Na⁺) and potassium (K⁺) ions from and to the exterior, in alternative form.
When the pump opening is inside it has a high affinity for Na⁺ ions, which it introduces into the cell. Once Na⁺ is transported, the pump changes its configuration, releases the Na⁺ ions and has its affinity increased by the K⁺, to which it binds and transports to the outside. This implies a primary active transport type.
The cotransport, a secondary active transport, can carry out the transport of molecules and ions simultaneously, since the configuration of the transporting protein allows it. An example of this is the sodium-glucose pump.
The Na⁺-K⁺ ATP-ase pump, being an alternate, non-simultaneous form of transport, is not considered a co-transport.

to the function of photosynthesis)l
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs , "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Schematic of photosynthesis in plants. The carbohydrates produced are stored in or used by the plant.
Overall equation for the type of photosynthesis that occurs in plants
Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and terrestrial vegetation. Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.
In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose.
The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth, which rendered the evolution of complex life possible. Today, the average rate of energy capture by photosynthesis globally is approximately 130 terawatts, which is about eight times the current power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91–104 petagrams) of carbon into biomass per year.
The fact that plants receive some energy from light—in addition to air, soil, and water—was discovered in 1779 by Jan Ingenhousz.

What is this process called?
A. oxidation
B. crystallization
C. altering minerals
D. organic mineral formation
Answer:
d
Explanation:
Crystallization generates solids by organizing atoms or molecules into a crystal structure. Crystals develop via solution precipitation, freezing, or rarely gas deposition. Therefore, option (B) is correct.
What is crystallization?The formation of a solid involves a process known as crystallization, in which the constituent atoms or molecules become highly ordered into a structure known as a crystal. Crystals can form in a number of different methods, including by precipitating from a solution, freezing, or, although this occurs less frequently, deposition directly from a gas.
There are two primary stages involved in the crystallization process. The first step is called nucleation, and it refers to the formation of a crystalline phase from either a liquid that has been supercooled or a solvent that is supersaturated. Crystal growth is the term given to the second stage of the process, which involves an increase in the size of the particles involved and ultimately results in a crystallized form.
Therefore, when a solution is evaporated, some of the solvent evaporates, leaving behind a saturated solution. Cooling the saturated solution forms crystals. Filtration removes crystals.

The NADH and FADH2 used by the electron transport chain are normally produced in the mitochondria; however. Select one:
a. NADH is also produced during glycolysis in the cytoplasm.
b. NADH is only produced and used in the mitochondria; FADH2 can be used elsewhere.
c. FADH2 is also produced by the citric acid cycle; NADH is not.
d. FADH2 produced in the mitochondria has more energy than does NADH.
Answer:
The correct answer is option A (NADH is also produced during glycolysis in the cytoplasm).
Explanation:
NADH is NAD + hydrogen, which is among the list of chemicals that produce energy for the body. It's among the vitamins that act as fuel for electrons during cellular respiration. NADH makes more ATP than FADH2 producing water during the electron transport chain.
During the electron transport chain, which is a step in aerobic respiration, both NADH and FADH2 supplies the much-needed H for the formation of ATP.
Glycolysis, which leads to the formation of ATP occurs in the cytoplasm gives energy for metabolism in the cells after is being broken down produces NADH.

If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
A. 52%
B. 24 %
C. 48 %
D. 26%
I need help plzz
Answer:
26%
Explanation:
Adenine pairs with thymine.
Guanine pairs with cytosine.
If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.
100 - 48 = 52
Then divide by 2 because you have guanine AND cytosine.
52/2 = 26
Therefore, your final answer is 26% of guanine is in the DNA molecule.
