A receptor is a sensor that monitors the environment and responds to changes by sending information along a pathway to a control center.
In the field of biology, a receptor can be described as the part of the body that detects a change in the external environment. Receptors are usually nerve endings present in the sensory organs of the body. For example, when your hand touches something hot, the nerve endings of the skin of your hand detect it.
The sensory receptors, after detecting changes in the external environment, send signals to the control center of the body. The control center is the central nervous system of which the brain and spinal cord are a part.
The control center interprets this information and sends a response through the effector motor neurons.

Herbalists are those who gather or trade in herbs, particularly those used medicinally. Herbalists look for the underlying cause of sickness.
Based on the signs or diseases a patient explains during the consultation, practitioners will select herbs. Additionally, Herbalists will conduct a clinical examination, looking at specific body parts, and write a unique prescription. Herbalists can provide secondary or primary healthcare, and they typically start by diagnosing the patient based on their medical background. This past contains elements like eating preferences and way of life. With the patient's cooperation, the herbalist would typically develop a herbal strategy to treat the issue after identifying it. This herbal therapy could include a particular form of complementary medicine, like Ayurvedic medicine.

Seaweed cover increased the most when both urchins and limpets were removed. How might you explain this result?
Only urchins were removed, which resulted in an increase in limpet population and decrease in seaweed cover.
Sea urchins and limpets both consume seaweed, making them competitors for it. The limpet population grows as a result of the urchin removal, having a greater impact on the amount of seaweed present.The biodiversity of these settings can be wiped out if seaweed builds up in bodies of water. This issue arises when there is an overabundance of algae, which, in search of additional food, proliferate aggressively and cause pollution. Additionally, life might end where there is pollution. Hedgehogs and limpets can play a significant role in this situation because they feed on seaweed, which helps to control the problem of its excessive profusion. A lot of research has been done to determine the value of these two species in preventing pollution brought on by the growth of seaweed. When the sea urchins and limpets were removed in the study mentioned in the question above, seaweed cover rose significantly more than when only the sea urchins were removed. This most likely occurred because the limpet population expanded and the amount of seaweed was reduced when only the hedgehogs were eliminated.Learn more about the Seaweed with the help of the given link:

How is the action of epinephrine on blood flow to muscles in the fight-orflight response similar to the action of the plant hormone auxin in apical dominance (see Concept 39.2)?
The correct answer is The two hormones have opposing actions on various target tissues. Epinephrine increases blood flow to skeletal muscles and decreases blood flow to smooth muscles in the digestive system during the flight or flight reaction. Auxin encourages the growth of apical buds while inhibiting the growth of lateral buds in order to achieve apical dominance.
The adrenal glands and adrenergic neurons produce epinephrine, a hormone and neurotransmitter that is generally referred to as adrenaline. Two hormones generated by the adrenal medulla—epinephrine (adrenaline) and norepinephrine—start the body's fight-or-flight response (norepinephrine).
The airways open up as a result of the adrenaline reaction, giving the muscles the oxygen they require to fight or flee danger. Auxin, on the other hand, induces apical dominance, which is when a shoot's suppresses the growth of lateral buds to enable vertical growth.

Primary streak is the raised groove formed on the dorsal side of the two-layered embryonic disc.
Primary streak is fashioned on the dorsal facet of embryonic disc around fifteenth day of life and is answerable for the formation of notochord and the 1/3 germ layer namely mesoderm. The notochord is shaped through the addition of cells to its caudal cease because the primitive streak degenerates.
The germ layers expand early in embryonic existence, thru the device of gastrulation. for the duration of gastrulation, a hollow cluster of cells called a blastula reorganizes into number one germ layers: an internal layer, called endoderm, and an outer layer, called ectoderm.

One hormone molecule can stimulate the synthesis of hundreds of enzyme molecules. This known as Signal amplification.
Endocrine signalling involves the secretion of signalling molecules (hormones) by specialised endocrine cells, which are then transported through the bloodstream to act on target cells in distal body regions.Through their binding to particular hormone receptors, hormones cause changes in target cells. In this approach, hormones affect just those cells that have the required receptors, even though they circulate throughout the body and come into touch with a variety of cell types.The signal produced when the probe molecule hybridises to the target nucleic acid sequence is increased or amplified through signal amplification.

The formation of nerve tissues begins with the neutral tube. As a result, when the transplanted cells were placed in another embryo, they developed into nerve tissues.
Tadpoles with undifferentiated gonads can undergo male-to-female or female-to-male sex reversal depending on whether they are exposed to estrogen or androgen.
