Explanation:

A law is an observation; a theory is the explanation of that observation.

source: http://www.differencebetween.net/miscellaneous/culture-miscellaneous/difference-between-theory-and-law/

In science, a scientific law is a descriptive statement or mathematical equation that describes a natural phenomenon or pattern consistently observed in the natural world.

The correct statement is option c.

The statement explains what happens and is often based on empirical evidence obtained from repeated observations and experiments.

On the other hand, a scientific theory is a well-substantiated and comprehensive explanation of some aspect of the natural world. It goes beyond mere observation and provides an understanding of why and how a particular phenomenon occurs. A scientific theory is supported by a substantial body of evidence, and it can be used to make predictions about future observations or experiments.

Scientific laws and theories are both essential components of scientific understanding, and they are not ordered in terms of coming before or after each other.

Hence , C is the correct option

The rapid increase in adaptive immunity after a second antigen exposure is called Specificity.

When our body is exposed to antigen for second time a relatively faster and high intensity immune response is produced.

Antigen appears in the organism a second time, then the memory cells are already present at high levels, and produce a more rapid and much stronger immune response.

Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. This part of the immune system is activated when the innate immune response is insufficient to control an infection.

Chronic inflammation extending deep into the lining of the affected part of the GI tract can lead to abdominal pain, cramping, and diarrhea. This condition is most commonly associated with Crohn's disease and ulcerative colitis.

Both are types of inflammatory bowel disease (IBD) that cause inflammation in the gastrointestinal tract. Crohn's disease can affect any part of the GI tract from the mouth to the anus, whereas ulcerative colitis primarily affects the colon and rectum. Symptoms of these conditions include abdominal pain, diarrhea, and cramping, among others. Treatment often involves medication to manage inflammation and alleviate symptoms. Other conditions mentioned, such as cirrhosis, GERD, cholecystitis, diverticulitis, hepatitis, pancreatitis, intestinal obstruction, and peptic ulcer, can also result in abdominal pain and discomfort. However, the specific combination of deep inflammation, abdominal pain, cramping, and diarrhea is more characteristic of IBD, particularly Crohn's disease and ulcerative colitis.

Based on the experiment, you can determine the solute concentration by measuring the mass of the solute dissolved in a known volume of solvent and calculating the molarity. This can be done using a balance and volumetric flask or through titration methods.

To be more specific, first weigh the mass of the solute and dissolve it in a known volume of solvent, using a volumetric flask for accuracy. Then, calculate the molarity (moles per liter) by dividing the moles of solute (which can be determined by dividing the mass of the solute by its molar mass) by the volume of the solution in liters.

Alternatively, you can use a titration method, where a solution with a known concentration is added to the sample until the reaction is complete. By knowing the volume of titrant added and its concentration, you can determine the concentration of the solute in the sample.

The process occurring at the sensory receptors that convert physical energy into coded neural activity that the nervous system can process is called c. sensory transduction

In the field of science, we can define sensory transduction as a process by which a change in the physical environment is recognized by the sensory receptors. This information is changed into electrical signals that are transported along the neurons. The neurons transmit these action potentials to the CNS which interprets it and sends signals for producing a response through the effector neurons.

The sensory receptors detect any kind of environmental change and the physical energy of the neurons changes into a neural activity that is initiated by the nervous system in recognition of this change by the sensory receptors.

Answer:

It is exclusively a philosophically naturalistic perspective of universal reality that is allowed in any hypothesis of the origin of life, meaning only the interactions of elements that through naturalistic processes that are allowed for any postulation of what could precede the appearance of life. However, chemical evolution that attempts to explain the interaction of abiotic materials, elements, compounds, molecules and assemblies are mythological, just as is Darwin's "warm little ponds" and increasingly, the primordial soup of Oparin-Haldane. There are no naturalistic processes capable of any significant organization and assembly of biochemical compounds. The physics law of entropy does permit assembly of some materials, even simple amino acids and sugars, but nothing even close to what is required in an organism, even of the simplest construction. The lab experiments that have been performed and have demonstrated some biochemical assembly have been intelligent design, highly managed efforts that are not geochemically relevant to primordial earth conditions.

The ureters are the tubes that carry urine from the kidneys into the urinary bladder. They are made of smooth muscle fibers. Uretic peristalsis is the name of this procedure. The smooth muscular contraction in the ureter tubes during ureter peristalsis results in the continual movement of urine toward the bladder.

The ureter is 25–30 cm long and 3–4 mm in diameter in adults. One of the vital organs of the urinary tract that regulates the movement of urine is the ureter.The two ducts or structures that link the kidneys and bladder are referred to as the ureters. These smooth muscle structures' primary job is to move or convey urine from the kidney, where it is produced and filtered through blood, to the bladder, where it is stored before passing through the urethra for elimination. The ureters also start in the renal pelvis, a region of the kidneys, before moving downward to the bladder. The ureter, then, is the organ responsible for transferring urine from the kidney to the bladder.

In the absence of glucose and in the presence of lactose, the lac repressor is bound to the allolactose, and the lac operon can start.

A lac operon is an inducible operon that is activated in the presence of lactose in the outer surroundings of the bacteria. Operon is a series of genes present in the bacterial DNA.

When the lactose is present, the repressors move to bind the allolactose, and as a result, the RNA polymerase can access the lac operon. The repressor has more affinity for allolactose than the operator. RNA polymerase, along with cAMP and CAP proteins, initiates the transcription of lac operon. The transcript has genes for galactosidase, permease, and transacetylase.

Hence, in the absence of glucose and in the presence of lactose, the lac repressor is bound to the allolactose.

Explanation:

Two substances are both reabsorbed in the kidneys are Glucose and salts. The correct option is a.

Glucose and salts are both substances that are reabsorbed in the kidneys. During the process of urine formation, the kidneys filter waste products, excess water, and solutes from the blood. However, some essential substances need to be retained in the body, so they are reabsorbed back into the bloodstream.

Glucose is a sugar and an important source of energy for the body. Normally, all filtered glucose in the kidney tubules is reabsorbed back into the bloodstream to maintain the body's glucose balance. The reabsorption of glucose occurs primarily in the proximal tubules of the nephrons.

Salts, such as sodium, potassium, and chloride, are essential electrolytes for various physiological processes in the body. The kidneys regulate the balance of these electrolytes by reabsorbing them from the filtrate back into the bloodstream. The reabsorption of salts occurs throughout the different segments of the renal tubules, primarily through active transport mechanisms.

Option b (glucose and starch), option c (glycogen and salts), and option d (glycogen and starch) are incorrect because starch and glycogen are not substances that are reabsorbed in the kidneys. Starch is a complex carbohydrate found in plant-based foods, while glycogen is a storage form of glucose in animals. These substances are typically broken down into glucose and then reabsorbed if necessary. However, in the context of kidney reabsorption, glucose refers to the direct reabsorption of filtered glucose molecules. Thus, the correct option is a.

Hypertonic solutions are those in which the solute concentration is higher than that of another solution, such as the intracellular solution found inside a cellular.

Hypertonic solutions are those in which the solute concentration is higher than that of another solution, such as the intracellular solution found inside a cellular.

When a cell is submerged in a hypertonic solution, water moves out of the cell more quickly than it does in.

Hypotonic solutions contain fewer solutes than other solutions do.

When a cell is submerged in a hypertonic environment, water moves more into the cell than being out of it.

Substances that are isotonic have the same strength as another solution.

When a cell is submerged in an isotonic solution, water enters and exits at the same rate.

The pupil's research with a plant cell in a salt solution revealed that the plant cell had a regular similar structure to that of a typical plant cell, proving that the fluid was isotonic.
