Which statement is true about Earth's outer core? A. It is believed to be made mostly from copper deposits. B. It is the outermost layer of the planet. C. It is composed of liquid metal. D. It is the thinnest layer of the planet.
Answers
Answer: c
Explanation: makes sense
The Earth's outer core is mainly composed of the liquid metals such as iron and nickel. Thus, the correct option is C.
What is the outer core of the Earth?The outer core begins approximately in the range of 2,889 km or 1,795 miles beneath the Earth's surface at the core-mantle boundary of the Earth and ends at 5,150 km or 3,200 miles beneath the Earth's surface at the inner core boundary of the Earth.
The outer core of the Earth is mostly composed of liquid iron and nickel. The Nickel and Iron alloy of the outer core is very hot, between 4,500° and 5,500° Celsius temperature. The outer core of the Earth is mostly made up of iron and nickel elements. This alloy is often written as NiFe because it is a combination of their chemical element symbols.
Therefore, the correct option is C.

Which one of the following descriptions, pertaining to a scientific hypothesis or theory, is NOT true?A. it must be possible to devise experiments so it can be testedB. it must be possible - at least in principle - to prove it false (i.e. find evidence that disproves it)C. other scientists must be able to repeat the experiment and test the same ideaD. it must only yield evidence that proves the hypothesis or scientific theory is correct and accurateE. it must deal with evidence that is empirical (i.e. the kind that can be observed)
Answers
A scientific hypothesis or theory does NOT have to just produce data that supports its validity and accuracy, as is implied by the aforementioned description. Here option D is the correct answer.
In science, a hypothesis is an explanation that has not yet been fully verified or disproven, whereas a theory is an explanation that has been supported by a substantial amount of evidence and has withstood rigorous testing.
A scientific hypothesis or theory must be testable, meaning that it must be possible to devise experiments to evaluate it. Additionally, the hypothesis or theory must be falsifiable, meaning that it must be possible to prove it false or find evidence that contradicts it. This is critical to the scientific process because it ensures that ideas are subjected to rigorous testing and scrutiny.
Furthermore, the results of experiments must be repeatable, meaning that other scientists should be able to conduct the same experiment and get the same results. This allows for the confirmation of results and builds scientific consensus.

why do sporangiophores grow vertically whereas rhizoids grow downwards
Answers
Answer:
The sporangiophore grow vertically which is in an upward direction because it is positively phototrophic. This means that it grows towards the ray of light from the sun which is found above. This is usually due to the provision of solar(light) energy from the sun which is used for the photosynthetic processes of the plants
The rhizoides grow downwards because they are positively geotrophic. This means they grow according to the force of gravity which acts downwards.

which of the following statements about photoreceptors is true? when s-cones and m-cones have low activity but l-cones are strongly activated, we perceive the color red. rods can be activated by weak light intensity but are most active when light is bright. cones provide higher visual acuity than rods because there are more cones than rods. cones are present only in the region of the retina called the fovea.
Answers
The true statement about photoreceptors is Rods can be activated by weak light intensity but are most active when light is bright.
Option (b) is correct.
Rods are photoreceptor cells in the retina that are responsible for vision in low light conditions, such as at night. They are highly sensitive to light and can be activated by weak light intensity. However, they are most active in low-light conditions and less active in bright light.
Option a) is incorrect because when S-cones (short-wavelength cones) and M-cones (medium-wavelength cones) have low activity but L-cones (long-wavelength cones) are strongly activated, we perceive the color yellow, not red.
Option c) is incorrect because cones provide higher visual acuity than rods not solely because there are more cones than rods, but because cones are specialized for color vision and have a higher spatial resolution.
Option d) is incorrect because cones are not present only in the fovea. While the fovea contains a high density of cones, they are also present in other areas of the retina, although in lower numbers.
Therefore, the correct option is (b).

glycolysis begins with a(n) ________ stage(s).
Answers
Glycolysis is the first step in cellular respiration, which is a process that extracts energy from glucose.
It is present in the cytoplasm of the cell and begins with the breakdown of glucose (a six-carbon molecule) into two three-carbon molecules of pyruvate. This process requires an investment of two ATP molecules. There are 10 reactions in glycolysis, which can be divided into two stages, namely the energy investment phase (reactions 1-5) and the energy payoff phase (reactions 6-10).Answer: Glycolysis begins with a one stage. Explain:Glycolysis begins with a six-carbon glucose molecule breaking down into two three-carbon pyruvate molecules.
This process of glycolysis is a ten-step process that occurs in the cytoplasm of the cell. These steps can be divided into two stages: the energy investment phase and the energy payoff phase.In the energy investment phase, the cell has to invest two ATP molecules to activate glucose and ensure its split into two molecules of glyceraldehyde 3-phosphate (G3P). The first stage of glycolysis consists of reactions 1-5 and is the energy investment phase. In the second stage, reactions 6-10, the energy payoff phase, the cell recovers its investment by producing four ATP molecules, yielding a net gain of two ATP molecules.

moving away from the body toward the end of a limb is moving in a/an ________ direction.
Answers
Moving away from the body toward the end of a limb is moving in a distal direction.
Anatomical directions are used to describe the position and movement of body parts.
"Distal" is a directional term used to describe movement away from the center of the body or from the point of attachment of a limb to the trunk of the body.
In contrast, "proximal" refers to movement toward the center of the body or toward the point of attachment of a limb to the trunk of the body.
Therefore, if you are moving away from the body toward the end of a limb, you are moving in a distal direction.
For example, if you raise your arm, your hand moves away from your body and toward the end of your arm, which is a distal movement.

in the limbs, which tends to be a muscle's more distal attachment?
Answers
In the limbs, a muscle's more distal attachment is typically the attachment point that is farther away from the body's midline or the center of the body.
In anatomical terms, "distal" refers to a location that is further away from the point of origin or attachment, while "proximal" refers to a location that is closer to the point of origin or attachment.
In the context of the limbs, such as the arms and legs, muscles generally have two points of attachment: a proximal attachment and a distal attachment. The proximal attachment is typically closer to the body's midline or center, while the distal attachment is farther away from the body's midline or center, towards the end of the limb.

the contents of which dialysis tube are initially isotonic to the distilled water in the beaker?
Answers
In order to understand which of the tubes are isotonic, we must understand that tonicity is the osmotic pressure generated by the difference in concentrations of two solutions.
In simpler terms, when we have two solutions with different concentrations of solute, this difference causes osmosis to occur. The pressure that this reaction produces is known as osmotic pressure. Tonicity is the comparison of these solutions to one another and can be classified as:
Hypertonic solutionsHypotonic solutionsIsotonic solutionsA hypertonic solution is one whose concentration of solute particles is higher than that of the solution it is being compared to. Meaning that this solution is placed on the other side of a membrane would cause water to move to it through osmosis. Conversely, a hypotonic solution would produce the opposite reaction by having a lower concentration.
Isotonic solutions, on the other hand, are those whose concentrations are equal to the solution they are being compared to. This means that if placed on the other side of a membrane they would remain in a balanced state and not cause a reaction. An isotonic solution to distilled water would be more distilled water.
