In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by ________.
In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by Gustav Theodor Fechner.
In the field of science, psychophysics can easily be described as a combination of stimulus and sensation as these two terms are often considered to be one, but are different. The branch of psychophysics combines the branch of psychology with the branch of physics.
The term 'psychophysics' first came forward by Gustav Theodor Fechner. He was a well-established person in the field of psychology as well as physics. The reason behind bringing the concept of psychophysics, according to Fecher was that the relation between stimuli and sensation needs to be understood.
Over time, the complex ways in which the mind of a person, and its perception relates to the stimuli are studied under the complex branch of psychophysics.

what is active transport?
A. an organisms way of getting materials to its community
B. a cells way of transporting materials that uses energy
C. the nucleus’s way of transporting genetic information
D. when peroxisomes moving materials in a cell
Active transport is a cells way of transporting materials that uses energy.
What is active transport?Active transport is a type of passage through the membrane in which energy is expended for transport to occur. There is a movement of molecules from a region where there is a lower concentration of this molecule to where there is a higher concentration, which is against the concentration gradient.
When overcoming a force, it will need energy to be able to generate this transport, so the transport proteins will need ATP to generate this movement of molecules.
One of the best known molecules that performs this type of transport, and one of the most important in the cell to maintain ion homeostasis inside and outside the cell, is the sodium-potassium ATPase pump, which pumps sodium ions out of the cell and pumps potassium ions into the cell.
Therefore, we can confirm that active transport is a cells way of transporting materials that uses energy.

Explanation:
The motion of the block is decreasing with the period of time. So, the correct option is (J).
What is Motion?
Motion is defined as when an object changes its position with respect to time. In other words, the act of moving or the process of being moved. It can be described in many words such as displacement, distance, velocity, acceleration, speed etc.
The motion in a long line or a curve is called as Translation whereas the motion which changes the orientation of the body is called Rotation. In both the cases, all the points in the body have same velocity (having speed with direction) and same acceleration which is defined as time rate of change of velocity.
Motions are of two types:
1. Translation
2. Rotation
Some examples of motions are running, cycling, swimming, eating, drinking etc. Motion is caused by force, when we apply a force motion occur.
Thus, the motion of the block is decreasing with the period of time. So, the correct option is (J).

The shape of a blackbody curve depends on the single property of the temperature of the blackbody. It is the only single property of the blackbody that affects the shape of a blackbody curve.
Temperature completely determines the shape of a blackbody curve as it shows a wide variety of results by their amount in the increased or decreased state.
Blackbody Curve is the curve that represents the intensity of spread of the radiation that is emitted by any type of object. The curve drawn sometimes refers to a mathematical type of idealization which is known as a blackbody as it is an object that is capable of absorbing all kinds of radiation falling upon it.
Each curve will show an intensity of radiation that exists over a wide range of wavelengths as it is emitted at a particular temperature by the blackbody.

glucose enters the epithelial cells of the small intestine against its concentration gradient. select the best explanation from the statements.
The best statement which explains is 'Glucose is co-transported with Na+, which moves down its concentration gradient into the cell'.
It is because the sodium/potassium pump is located in the plasma membrane of the cells.
To transfer the glucose material across the membrane, the Na+/K+ pump utilizes three molecules of ATP to shift potassium ions inside the cell and derives sodium ions outside the cell.
As a result of this, Na ions' concentration increases outside the plasma membrane while the concentration of potassium is higher inside the membrane.
This process is also known as secondary active transport because it drives energy from the primary active transport process.

Genetic and epigenetic changes compound over time to cause cancer. While aging and chronic inflammation are the major causes of epigenetic changes, carcinogenic substances, UV radiation, and other conditions can also cause genetic changes. Our prior exposure levels and life history are reflected in the accumulation and patterns of changes in normal cells. The majority of accumulated changes are regarded as passengers, although they are linked to cancer drivers as they accumulate. Although only hypothesized for genetic changes, this has been demonstrated for aberrant DNA methylation. However, modern technology has made it possible to assess uncommon point mutations, and research has revealed that the rates of their accumulation do actually correspond with cancer risk.

Answer:
D
Explanation:
its just not any other one
Our soil cleans our water, feeds our trees and crops with vital nutrients, and controls numerous significant greenhouse gases in addition to helping to maintain the Earth's temperature. Thus option D is correct.
What is the soil impact on Earth climate?On a smaller scale, soil can also affect climate. More so than drier, looser soils, wetter or denser soils hold heat and stabilize the environment from temperature variations.
In deserts, the temperature can rise by more than 60 °F in a single day. The largest repository for terrestrial carbon is healthy soil. In the carbon cycle, soils are essential because they absorb carbon from decaying plant tissue.
By storing carbon (carbon sequestration) and reducing greenhouse gas emissions in the atmosphere, soils can be effectively managed to mitigate climate change.

How many variations do you observe?
Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.
