The stimulus signal detection concept states that detection of a stimulus depends on the stimulus's intensity, the surrounding environment, or the individual doing the detection.
What is stimulus Short answer?An stimulus is anything that has the potential to alter one's behavior or physiological body. The plural of stimulus is stimuli. Stimuli might be internal or external. Another example of an external stimulus is the way a drug effects your body.
What causes stimulus?Its environment changes in a way that can be noticed. Receptors: Receptors are devices that transform ambient stimuli into electrical nerve signals. Neurons: Through neurons, nerve signals are sent from the peripheral nervous system to the brain. Effectors: In response to the stimuli, effectors create a reaction.

which of the following statements about viruses is false? group of answer choices viruses contain a protein coat. viruses exclusively use their own enzymes. viruses have genes. viruses contain dna or rna but never both. viruses use the machinery of the host cell.
Viruses use their own catabolic enzymes , Viruses are unable to synthesize catabolic enzymes on their own to generate energy. They could only do so by expressing their genomes in the host cell's nucleus (for DNA viruses) or cytoplasm (for RNA viruses).
Viruses are metabolically inactive and must rely on cell metabolic activities to create component parts and replicate new viral copies. Often, the cell is dormant at the time of infection, but the infection alters the cell's metabolic activity.
Viruses cannot make or store adenosine triphosphate (ATP), so they must rely on the host cell for energy and all other metabolic processes

What is formed during transcription?; What is the complementary strand of RNA that is produced during transcription?; What is produced during transcription RNA polymerase?; What is the product of transcription in RNA?
The act of copying information from a strand of DNA into a fresh messenger RNA molecule is transcription (mRNA). The transcription enzyme RNA polymerase links the RNA nucleotides during transcription.
Primary transcript RNA is created. One of the two exposed DNA strands, known as the template strand, serves as a template for transcription. The RNA product is essentially similar to the nontemplate (or coding) strand of DNA and is complementary to the template strand. Messenger RNA is the molecule created by RNA polymerase during transcription. DNA unzips during transcription to reveal the genetic information. RNA polymerase reads the DNA to produce messenger RNA, which is a complementary message of DNA (mRNA).RNA, which may be found as mRNA, tRNA, or rRNA, is the end result of transcription, whereas a polypeptide amino acid chain, which eventually becomes a protein, is the end product of translation. In eukaryotic species, translation takes place in the cytoplasm and endoplasmic reticulum whereas transcription takes place in the nucleus.

So recently my baby turtle seems to have died i still have him im not sure if hes really dead or not how do i know if hes dead and do turtles have muscle memory?
Answer:
I'm sorry to hear about your turtle. It can be difficult to determine if a turtle is dead or just inactive, as they are known to have periods of inactivity. Here are some signs that may indicate that your turtle has passed away:
Lack of movement: If your turtle is not moving or responding to stimuli, it could be a sign that they have passed away.
Lack of respiration: You can check for signs of respiration by gently placing your hand near the turtle's nostrils and watching for any movement of the chest or abdomen. If you do not see any movement, it could be a sign that the turtle has stopped breathing.
Lack of reflexes: If you gently pinch the skin on the turtle's leg and do not get a reflexive response, it could be a sign that the turtle has passed away.
It is important to note that turtles can go into a state of torpor, where they become inactive and their bodily functions slow down significantly. This can sometimes be mistaken for death, so it is always best to consult with a veterinarian if you are concerned about the health of your turtle.
As for muscle memory, it is not clear if turtles have the same type of muscle memory as humans. However, it is known that turtles can learn through repetition and can remember certain behaviors and patterns.
a plant that was heterozygous for purple axial flowers was pollinated by a plant that had white terminal flowers. determine the genotype of each parent, the gametes that are possibly produced, and the resulting possible genotypes of the offspring. then calculate the genotypic ratio and the phenotypic ratio of the potential offspring.
The genotypic and phenotypic ratio of the offspring is 1:1 when a plant with heterozygous purple axial flowers is pollinated by a plant with white terminal flowers.
Let the gametes for the Heterozygous Purple Flower be (Pp), P, and p.
Let the gametes be Recessive White Flower: pp.
Fusion produces Pp (purple) and pp as a result (white).
There is a 1:1 phenotypic ratio.
It is therefore 50% purple and 50% white.
The children produced when a heterozygous purple flower (Pp) and a recessive white flower (pp) are crossed have the genotypes (Pp), (Pp), (pp), and (pp). Consequently, 50% of the offspring have purple flowers (Pp), while 50% have white flowers (pp).

What results in genetic modification?Mutations can be the result of viral infection, exposure to mutagens, or mistakes in DNA replication during cell division. Somatic mutations—those that take place in body cells—cannot be passed on to progeny, whereas germline mutations—those that happen in eggs and sperm—can.

when you added primary antibody to the wells, what happened if your sample did not contain the antigen
when you added primary antibody to the wells, If the antigen was not detected, the main antibody was washed off.
Antibodies and proteins shield you from harmful chemicals when they come into touch with your body. Antibodies are created by your immune system to bind to these foreign chemicals and remove them from your body. Immunoglobulin is another term for an antibody. A foreign substance that enters your body is referred to as an antigen. This includes venom, allergens, bacteria, viruses, fungus, and other poisons. Your immune system makes an antibody protein that it employs to find and eliminate particular antigen. Surface molecules on antigens are different from ones your body typically produces. Your immune system thus recognizes an antigen as soon as it enters your body. Your immune system requests antibody defense in order to fight against this antigen invasion. The B cell produces antibodies (specialized white blood cells). A B cell expands and clones when it comes into touch with an antigen. These plasma cells, also known as cloned B cells, continuously produce antibodies into your lymphatic and blood systems.

The following characteristics of carrying oxygenated blood, alteration of vessel diameters are indicative of arteries.
Arteries are deep inside our muscles which carry oxygenated blood from left ventricle to all other parts of the body. However, the function of pulmonary is completely opposite to the arteries. Arteries are considered as the primary resistance vessels because they distribute the blood flow into capillary beds. The arterial blood circulation is pulsatile, which means that the blood flow is rhythmic and the intermittent propagation of a fluid occurs through the vessels. The presence of elastin fibers in the large blood vessels enables arteries to increase in size as arteries are under high blood pressure.

In contrast to most other breeds, the pinto horse is classified according to its color rather than its genetic heritage. The Pinto is considered a legitimate breed in America.
Pintos have a black base hue with sporadic white spots on top of it. Any breed or particular conformation may exhibit the Pinto colour. The Pinto Horse Association of America, on the other hand, does not accept horses of Appaloosa, Draft, or mule ancestry or traits. Since its colouring offered a natural concealment, the Pinto has historically been thought of as a horse that American Indians preferred as a war horse in the American west.
Since the Pinto is bred for colour, its conformation is not constant. The term "Piebald" is frequently used to describe horses when the deeper hue is black.
