Factors in the environment that an organism reacts to, such as light, temperature, sound are known as stimulus.
In the field of biology, a stimulus can be described as any kind of change in an environment that is perceived by the sensory receptors of an organism. In order to survive a change, the body has to produce a response to the stimulus.
When a change in the environment i.e stimulus is detected by the sensory receptors, a signal is carried to the central nervous system (CNS). The central nervous system (CNS) determines this change and sends a message through the effector motor neurons with a necessary response action.
Any change in the environment, such as a change in temperature, light intensity, or sound intensity is perceived by the sensory receptors and is a stimulus.

The shape of a blackbody curve depends on what single property of the blackbody?.
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.

a transcutaneous pacemaker is most likely an intervention for which dysrhythmia? a. second-degree atrioventricular block, type i b. second-degree atrioventricular block, type ii c. wolff-parkinson-white syndrome d. wandering atrial pacemaker
A transcutaneous pacemaker is most likely an intervention for second-degree atrioventricular block, type ii dysrhythmia.
What is transcutaneous pacemaker?
A temporary method of pacing a patient's heart during a medical emergency is transcutaneous pacing (TCP), often known as external pacing. While some contemporary defibrillators can perform both tasks, transcutaneous pacing and defibrillation use pads and an electrical stimulus to the heart respectively. Defibrillation is used in more serious instances, such as ventricular fibrillation and other shockable rhythms. Electric current pulses are delivered through the patient's chest during transcutaneous pacing to stimulate the heart's contraction.
An unusually slow heart rate is the most typical transcutaneous pacing indication. By definition, bradycardia is a heart rate in an adult patient that is less than 60 beats per minute.

A It possesses energy inversely proportional to its frequency
B
It is a longitudinal wave.
С
It transfers energy without transferring mass,
D
It diffracts and accelerates in air
Answer:
Answers for the whole test are:
1.Infrared waves have lower frequencies than ultraviolet waves. Since frequency and energy are directly proportional, infrared waves also have less energy than ultraviolet waves.
2.The student should model a convex lens because it directs light toward the center of the lens.
3.It transfers energy without transferring mass.
4. to disinfect surgical rooms
5. X-rays would be best because they are high-energy waves that can penetrate solids.

What hormone, released from the pancreas in response to a low blood glucose level, acts to raise blood glucose back to normal?.
When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon. This hormone helps blood glucose rise back up in multiple ways: It causes the liver to convert stored glucose into a usable form and then release it into the bloodstream.

what would be the result in macromolecule structure and function if the world was based on a small nonpolar lipid
Changes is macro molecule structures are expected among other things.
Briefing :There would be significant changes to proteins and carbohydrates if the Earth were built on a tiny non-polar lipid rather than water. Basic alterations in an organism might include solubility, catabolism, metabolism, and absorption. Because there aren't enough dissolved media, a lot of water-soluble material would become immobile.
However, other stuff that is soluble in fat will be very mobile and well absorbed. Sessile organisms that rely on nutrients that are dissolved in water for absorption, such as trees, will lose this capability. Finally, abiotic variables like precipitation and rock weathering will be affected. There will no longer be polar cap freezing or ice melting, and there will be an influx of a non-evaporating liquid.

people of india confound traditional racial categories because they fit most closely in terms of biological characteristics with people from europe, yet many have dark skin. '
Indians may closely resemble Europeans in terms of biological traits due to genetic allele frequencies.
The oldest skeleton from Europe that has been found so far is anatomically modern and dates to between 34,000 and 36,000 years ago. It was found in Romania's Carpathian Mountains. Conclusions drawn from the fossil evidence are supported and expanded by data already available on human genetic variation.
The conventional racial divisions, according to some observers, is biologically and genetically justified by these patterns of variation. According to their claims, the distribution of humans among sub-Saharan Africans, European, West Asians, and North Africans, Eastern Asians, Polynesians and other Oceanian residents, and Native Americans largely corresponds to the grouping of the continents.

Answer:
mitosis
Explanation:
The cellular process that enables the cells to grow and develop into tissue is mitosis.
Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.
Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by mitosis so as to replace the damaged cells due to the injury. By doing so, the injured area heals.

Cancer cells show no contact inhibition. Therefore, cell growth and division does not stop.
True
False
Answer:
Cancer cells are immortal and keep on dividing for an unlimited number of times. Cancer cells pile on top of one another and grow in multiple layers, forming a tumor. Cancer cells keep on dividing, even when stimulatory growth factors are absent, and they do not respond to inhibitory growth factors.
The statement "Cancer cells show no contact inhibition. Therefore, cell growth and division do not stop" is true.
What are cancer cells?
Cancer cells are abnormal cells that grow rapidly without stopping. These cells cause tumors because of unstoppable cell growth.
The amount of times that cancer cells can divide is infinite because they are immortal. A tumor is created when cancer cells stack on top of one another and grow in numerous layers.
Even in the absence of stimulator growth factors, cancer cells continue to divide and do not react to inhibitory growth factors. No contact inhibition is a mechanism that is used for stropping cancer and this inhibition is not present in cancer cells, that's why they divide rapidly.
Therefore, the statement is true.

Answer:
cells come from cells
Explanation:
The component of cell theories is that all cells come from already existing cells by division.
The component of the cell is that it is the primary element of life and that all the living things are made of one or more cells.
New cells come from the old ones by division and it means that no living thing can come into being through the non-living thing.
