what type of molecules diffuse through the cell membrane without using a channel protein ?
The molecules diffuse through the cell membrane without using a channel protein are as follows:
Gases (such as O₂ and CO₂), hydrophobic molecules (such as benzene), and small polar but uncharged molecules (such as H₂O and ethanol) are able to diffuse across the plasma membrane. Other biological molecules, however, are unable to dissolve in the hydrophobic interior of the phospholipid bilayer.Ions such as [tex]Na^+, K^+, Cl^-[/tex] can't get through due to their charge.Molecules such as glucose, sucrose, proteins, and starch cannot diffuse through cell membrane due to their large size.Learn more:

Where in this area would a lake or marsh most likely form? A. A B. B C. C D. D
Answer:
Option (B)
Explanation:
Lakes and marshes are generally formed in the areas where the elevation is less. They are the region where the water bodies remain stagnant i.e. no flowing of water takes place. These are not a part of the huge oceans and are usually surrounded by land on all the sides. They can be comprised of salt water or fresh water and are comparatively larger than ponds in terms of size.
Thus, the point B is the most favorable location for the formation of lakes and mashes as it is located near the mean sea level.
Hence, the correct answer is option (B).

A molecule stimulates a target cell via a receptor.
PLEASE HELP!
*Please and Thank You*
It is C. A message is distributed across the plasma membrane.
The correct answer is (C) A message is distributed across plasma membrane.
Intercellular communication means the communication that takes place between two cells, gap junctions, target-receptor. This means the message is transferred between two cells and then carry forward by other cells like a cascade or signal transduction. When a message is transferred across plasma membrane this means that no other cell is involved in it. The message is transferred from one organelle to other within the cell. Inter cellular response is not restricted only upto a single cell.
two ways water travels from land to enter the ocean
Final answer:
Water enters the ocean from land via runoff and groundwater flow, integral parts of the water cycle.
Explanation:
Two ways water travels from land to enter the ocean as part of the water cycle are through runoff and groundwater flow. Runoff occurs when water from precipitation like rain or melting snow flows over the surface of the land and into rivers, lakes, and eventually reaches the ocean. Groundwater flow refers to water that infiltrates the soil, becoming groundwater, which moves through the ground and discharges into the ocean, completing the cycle.

what are the correct labels for this diagram of glucose catabolism
Glucose catabolism entails breakdown of glucose and other simple sugars to release energy initiated in a process called glycolysis. Energy is extracted and stored in the form of ATP and NADH. The diagram representing this process should include glucose, ATP, NAD+, pyruvate and two stages of glycolysis.
Explanation:Glucose catabolism, also known as glycolysis, is represented in a diagram showing the breaking down of glucose (a six-carbon sugar) to extract energy. The labels for this diagram would likely include glucose, ATP, NAD+, ADP, P; because glucose, in combination with ATP, NAD+ and inorganic phosphate, breaks down into pyruvate, introducing ATP and NADH. The output of this process is two pyruvate molecules, two ATP molecules, and two NADH molecules.
Another relevant detail here is the incorporation of the simple sugars including galactose, fructose, glycogen, and pentose which are catabolized during glycolysis. Amino acids connect to this process through pyruvate, acetyl CoA, and components of the citric acid cycle. In aerobic conditions, pyruvate enters the Krebs cycle, leading to the production of high-energy FADH2 and NADH molecules which provide electrons to the oxidative phosphorylation process, generating more ATP molecules.
In your diagram, you should also indicate the two phases of glycolysis. The first part includes trapping of the glucose molecule in the cell and using energy to modify it so that it can be split into two three-carbon molecules. In the second phase, energy is extracted from the molecules and stored in the form of ATP and NADH. All these elements make up an accurate diagram of glucose catabolism.

Some plants release toxic chemicals that kill or harm nearby plants. What type of example is this?
A. cooperation
B. mutualism
C. competition
D. parasitism
Answer: C. competition
Explanation:
Competition can be define as the ecological relationship in which one species is more superior over the other in deriving resources. In competition usually one species live and the population of other species may either decrease in abundance, or may extinct.
The release of toxic chemicals by the plants to harm nearby plants is an example of competition. This is because of the fact that the plants may face competition with other plants for resources such as sunlight, water and minerals. Therefore, a physiological response will be generated inside the plants so as to kill the neighboring plants.

What is the primary energy system to fuel cycling at 70% of VO2 Max for 15 minuets?
The oxidative energy system is the primary source of ATP for cycling at 70% of VO2 Max for 15 minutes, utilizing carbohydrates and fats due to the aerobic nature and duration of the activity.
The primary energy system to fuel cycling at 70% of VO2 Max for 15 minutes is the oxidative energy system. This system is best suited for activities like cycling that last longer than 2 minutes and up to several hours. Although the immediate energy system can generate ATP quickly for explosive activities lasting about 10-20 seconds, such as sprinting, and the anaerobic system can sustain high-intensity activity for roughly 1.3-1.6 minutes, cycling for 15 minutes at 70% VO2 Max falls well into the time range that depends mainly on the oxidative system. This system utilizes carbohydrates and fats to produce ATP, and it becomes the most efficient source of ATP production as the exercise duration exceeds 2 minutes and as the heart rate and breathing rate increase to supply more oxygen to the muscles.

How was the grand canyon formed?
how have scientists determined the earth's core is composed of iron and nickel?
Final answer:
Earth's core is predominantly iron and nickel, inferred from seismic data, its density compared to the Earth's overall density, and its composition mirroring that of metallic meteorites. The solid inner and molten outer core composition, along with the generation of the Earth's magnetic field, supports a dense, metal-rich core.
Explanation:
Scientists have determined the Earth's core composition through various methods that overlap in the fields of seismology, geochemistry, and astrophysics. Seismic waves, created by earthquakes, have different speeds when they travel through solid and liquid matter, allowing scientists to characterize the inner and outer core. Observations show that the inner core is solid, primarily composed of iron and nickel, while the outer core is liquid, believed to be mostly molten iron potentially mixed with lighter elements such as sulfur and oxygen.
Another critical piece of evidence comes from the overall density of the Earth, as established by its gravitational effects and rotation, which suggests a denser metallic core when compared to the less dense surface layers. Additionally, the similarity in composition to metallic meteorites rich in iron and nickel supports the theory that these heavy elements sank to form the Earth's core during its early formation when the planet was still molten, and density stratification could occur.
Furthermore, the Earth's magnetic field, generated by the motion of electrically conductive material in the outer core, implies the presence of a metallic, iron-rich fluid. Laboratory experiments under conditions replicating the core's environment suggest iron alloys are conductive and match the observed density, thereby confirming a metal-based core and its role in geomagnetic phenomena.
