The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.

Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.

A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.

Therefore, the mentioned statement about the nerve impulse is true.

Answer:

It explains facts and allows people to make predictions.

Explanation:

In everyday life, the word theory often means an untested hunch, or a guess without supporting evidence. A theory not only explains known facts but also allows scientists to make predictions of what they should observe if a theory is true.

In science, the term theory is applied only to ideas that are supported by a vast, diverse array of evidence. The term is also used in everyday life based on personal beliefs which does not support any strong evidence.

In science, a theory is a term applied to a well-explanation of an aspect of the natural world on the basis of empirical evidence that has undergone rigorous testing and evaluation. The process involves collecting and analyzing data and observations and hypotheses are based on the data obtained which form the basis of scientific theory. Therefore, scientific theory is an explanation that has been verified by scientific researchers.

However, the term theory is casually used in everyday language without any scientific proof. For example, someone may say "I have a theory that the universe fake". This fact is casually spoken by a person which is not based on any scientific fact.

Scientific theories are based on evidence supported by rigorous testing, while everyday theories are based on personal beliefs without any strong evidence.

Therefore, the term theory is also used in everyday life, which is based only on a personal belief, and not only on any scientific fact.

Non-falsifiable

Falsifiable

Falsifiability is the capability for some proposition, statement, theory or hypothesis to be confirmed wrong. That capacity exists as an important component of the scientific approach and hypothesis testing. In a scientific context, falsifiability exists sometimes regarded synonymous with testability.

The falsifiable hypothesis can be denied by tests done with the most delinquent technology. The non-falsifiable hypotheses on the other hand can't refuted as tests have confirmed them to be true.

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Answer:

your answer is B. Habitat Loss

Explanation:

What is the #1 cause for the loss of biodiversity?

Habitat destruction

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.

(b) a distant luminous object travels rapidly towards an observer.

Explanation:

Blueshift is observed when a distant luminous object travels rapidly towards an observer. The correct option is B.

The displacement of an approaching celestial body's spectrum toward shorter wavelengths is known as blueshift.

When an object moves away from us, the light it emits is known as redshift; when an object moves towards us, the light it emits is known as blueshift.

The blue and red shift of stars cannot be seen with the bare eye. There are several reasons for this.

First, even for an object moving at thousands of kilometers per hour, the effect is minor, with only a slight change in hue.

Red light, with both the longest wavelength, is at one end of the spectrum.

The shortest wavelength is blue or violet light. White light is a blend of all the colors in the color spectrum. It has every color of the rainbow.

Thus, the correct option is B.

Adrenaline

Explanation:

The adrenaline glands, located on top of both kidneys, are glands that produce hormones to regulate blood pressure, bodily functions, metabolisms, etc. Adrenaline is released whenever the blood is redirected towards the muscles, causing surges of energy. In general, adrenaline increases blood flow in your body, which causes the heartbeat to increase, or give the feeling of a racing heart. Between the football players and the heartbeat rate, they are getting rushes of adrenaline from either participating in the game or cheering on their team from the sidelines. Hope that made sense.

Implicit stereotypes are automatically activated and operate indirectly, and thus individuals may not be aware that they possess such beliefs. In contrast, explicit stereotypes are accessible to conscious awareness and are what individuals report when asked about group differences.

Explanation:

Please rate, thank me, have a good day

Implicit stereotypes operate automatically and indirectly, so people may not realize they have them. When asked about group differences, people report explicit stereotypes.

A stereotype is a preconceived notion or combination of traits that many people hold to be indicative of a certain kind of person or object. Stereotypes are traits that society automatically ascribes to particular groups of people in order to categorize them according to factors like age, weight, occupation, skin tone, gender, etc.

Since implicit stereotypes function subtly and automatically, people may not even be aware that they hold such beliefs. Conversely, explicit stereotypes are cognizable and are what people report when questioned about group differences.
