The tympanic membrane is also referred to as the eardrum. It distinguishes between the inner and outer ear.
Explain about the tympanic membrane?In response to sound waves passing through it, the tympanic membrane vibrates. The vibrations then reach the tiny bones in the middle ear. Following that, the middle ear bones convey the vibrating impulses to the inner ear.
When the tympanic membrane tears, a link between the middle ear and the external auditory canal might form. This condition is known as tympanic membrane perforation. An infection, trauma, or sudden changes in pressure can all cause the rapid development of otalgia, otorrhea, tinnitus, and vertigo.
A burst eardrum (tympanic membrane perforation) is a hole or tear in the fragile tissue separating the ear canal from the middle ear (eardrum). Eardrum ruptures can result in hearing loss.

what role does a transcription factor play in a signal transduction pathway?
Answers
Answer:
Signal transduction pathways allow different types of cells to respond differently to the same signal molecule. Signal transduction pathways convert a signal on a cell's surface to a specific cellular response.
The targets of such signaling pathways frequently include transcription factors that function to regulate gene expression. Intracellular signaling pathways thus connect the cell surface to the nucleus, leading to changes in gene expression in response to extracellular stimuli.
Is it a scientific theory or a scientific law that the characteristics of living things change over time?
Answers
Answer:
Scientific Theory
Explanation:
The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.
In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.
Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

similarities between organic and inorganic fertilizer
Answers
Answer:
Organic fertilizers are natural, in that the nutrients they possess are strictly comprised of plant- or animal-based materials. ... Cow manure, decaying leaves, and food compost are all forms of organic fertilizer. Inorganic fertilizer is synthetic, comprised of minerals and synthetic chemicals.
Explanation:
A plant stem's two main functions are to support the leaves and to transport materials
between roots and leaves. As a stem develops, it possesses three types of permanent
tissues: surface tissue, ground tissue, and vascular tissue. The surface and ground
tissues support and give structure to the plant. The vascular tissues are the transport
systems of the plant. The vascular tissues usually exist in one of three patterns and are
known as the phloem and xylem.
Both the xylem and phloem are made up of several different types of cells that make up
transport tubes for needed nutrients. In general, xylem nutrients (sap) travel from the roots
to the rest of the plant. Phloem sap is derived from photosynthesizing leaves and from
there is carried throughout the plant.

With regard to bone decalcification secondary to hypocalcemia, what an endocrinologist and an orthopedist have in common is that they both focus on calcium levels.
Explanation:
Endocrinology and traumatology are two different medical specialties, however they can together treat a person with a metabolic disorder affecting the bones.
In the case of a person with thyroid problems, where probably the parathyroid glands are affected, there are low levels of calcium in the blood —hypocalcemia— which affects the bones secondarily by decalcification, both the endocrinologist and the traumatologist will coincide in the treatment of the serum calcium levels:
Endocrinologist will treat the hormonal problem that produces low calcium in the blood. Orthopedist will indicate a calcium replacement treatment to improve the levels of the mineral in the blood, and restore the calcium lost by the bones.The joint treatment of both specialists can guarantee the recovery of a patient with problems in the metabolism of calcium.

2. b. gluconeogenesis
3. d. neither
4. b. gluconeogenesis
5. a. glycolysis
6. c. both
7. a. glycolysis
8. d. neither
Explanation:
Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.
Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.
Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.
Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.
Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.
Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
The opossum is a new arrival in southern Ontario. Its niche is similar to that of the raccoon. An opossum has a long, bare, rat-like tail. A raccoon has a long, bushy tail. How is this a selective advantage for the raccoon?

Its substrates, acetyl-CoA and oxaloacetate, may be the most important regulators of the citrate synthase process. Both are present in the mitochondria in amounts that are below citrate synthase saturating levels.
What causes citrate synthase to be activated and inhibited?In the first step of the cycle, when acetyl-CoA and oxaloacetic acid combine to form citrate, citrate synthase controls the rate of the reaction. High levels of ATP, acetyl-CoA, and NADH block it, which suggests that there is already a significant amount of energy available.
That which controls citrate synthase is an allosteric chemical.Succinyl-CoA, a later step in the cycle, NADH, ATP, or long-chain fatty acyl-CoA can all act as citrate synthase's negative allosteric modulators, depending on the kind of cell.

All DNA is composed of the four bases shown in the table. How is the pattern in the data useful for developing a model of DNA?
Answers
Answer:
The four bases shown in the table (adenine, thymine, guanine, and cytosine) are the building blocks of DNA, and they are arranged in a specific sequence to encode genetic information. The pattern in the data (i.e., the sequence of these four bases) is useful for developing a model of DNA because it allows us to understand how the genetic information is encoded and transmitted from one generation to the next.
By analyzing the pattern of the DNA sequence, scientists can identify genes, determine the function of different regions of DNA, and even predict the likelihood of certain genetic disorders. This information is important for many fields, including medicine, agriculture, and forensic science.
Additionally, the pattern in the data has helped scientists to develop models of DNA structure, such as the double helix model proposed by Watson and Crick in 1953. This model provides insight into how the DNA molecule is able to replicate and transmit genetic information accurately from one cell to another.
