A specified quantity with which any other quantity of the same kind is measured is called a Unit
An exact magnitude of a quantity that is used as a standard for measuring other quantities of the same kind is what is known as a unit of measurement. Law or tradition define and recognize it. Another quantity of that type may be expressed using a multiple of the unit of measurement. For instance, a length is a physical quantity.
When a physical quantity's system of units is changed, its value is only expressed in a different type of system of units, i.e., only its magnitude is changed when expressed in a different system of units. As a result, the magnitude of the quantity does not change with the change in the system of units. The sum, however, does not alter.To know more about quantity visit

What is the major contributor to the increase in antibiotic resistance in bacteria?
Answers
The biggest contributor to increasing antibiotic resistance in bacteria is their overuse.
What are antibiotics?
Antibiotics are medicines that fight, as their name indicates, infections caused by living beings, especially bacteria. What it does is kill bacteria or make it more difficult for them to grow. Antibiotics should not be taken improperly as this contributes to resistance when using them. This occurs when the bacteria adapt to this antibiotic and can resist its action, slowly increasing the resistance to that antibiotic by the bacteria from one generation to the next.
Therefore, we can confirm that the biggest contributor to increasing antibiotic resistance in bacteria is their overuse which promotes the evolution of bacteria into more resistant strains.

If an epithelium has all cells touching the basement membrane, but not all cells reach the apical surface, that epithelium would be called a ________ epithelium.
Answers
If an epithelium has all cells touching the basement membrane, but not all cells reach the apical surface, that epithelium would be called a simple columnar epithelium.
The single layer of cells that make up the simple columnar epithelium are taller than they are wide. This kind of epithelium borders the small intestine and is responsible for absorbing nutrients from the gut's lumen. The stomach has simple columnar epithelia as well, which secretes mucus, acid, and digesting enzymes.
A basement membrane adheres to the basal surface of every epithelial cell. The basement membrane binds a layer of epithelial cells together and offers some mechanical support.
Although some cells do not reach the apical surface, all of the cells are in contact with the basal lamina despite the illusion of stratification caused by the arrangement.

The density remains the same because changing the amount of the substance will reduce the mass & volume by the same value.
What is density?
Mass per unit volume is the definition of a material's density. Density, or mass per unit volume, is defined as the ratio of mass to volume. It gauges how so much "stuff" an object looks in relation to its volume (cubic meter or cubic centimeter).
In essence, density is an indicator of how closely together stuff is packed. The Greek scientist Archimedes is credited with discovering the concept of density, which is simple to calculate if you understand the formula and are familiar with the relevant units.

If the rate of atrial depolarization was normal while the rate of ventricular depolarization was slower than normal, where would you expect to find a dysfunction in the electrical conduction pathway of the heart?.
Answers
You will find a dysfunction in the QRS complex of the electrical conduction pathway of the heart if the atrial depolarization is normal and the rate of ventricular depolarization is slower.
The waveform QRS complex represents the second acrion, ventricular depolarization. Q,R,S waves are included in the QRS complex; in rare circumstances, the q wave may not be seen. QRS measurements consist of 1.5-3 tiny boxes and take 06-.12 seconds. It calculates the complex from the first deflection following the P wave to the point where the S wave hits the isoelectric line (Period of zero electrical activity).
Ventricular depolarization is facilitated in part by an auxiliary route (AP) that connects the atrial and ventricle and is therefore capable of transferring electrical impulses into the ventricle without using the AV-His Purkinje conduction system.

Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food.
What is Stomach?Humans and many other animals, including numerous invertebrates, have a muscular, hollow organ called the stomach in their gastrointestinal tracts. The stomach is a crucial organ in the digestive system and has a dilated configuration. Following chewing, the stomach participates in the gastric phase of digestion. Using enzymes and hydrochloric acid, it performs a chemical breakdown.
The stomach is situated between the oesophagus and the small intestine in humans and many other animals. To aid in food digestion, the stomach secretes gastric acid and digestive enzymes. The pyloric sphincter regulates how food that hasn't fully broken down (called chyme) moves from the stomach to the duodenum, where peristalsis takes over to move it through the rest of the intestines.

Answers
Answer: Carbon Dating though measuring Carbon-14 levels
Explanation:
Scientist measure the age of a fossil determined on the Carbon-14 level compared to the Carbon-12 level. This method works because:
All organisms after their death stop replenishing the amount of carbon in their body. That means that they will have an equal amount of carbon-12 and carbon-14 until they die. Unlike carbon-12, carbon-14 is unstable and overtime will go through beta decay. Overtime, a carbon-14 neutron will become a proton and release an electron, transforming into nitrogen-14.This leads to a drop in carbon-14 level, and because of this, geologist compare the level of carbon-14 to carbon-12 to determine how long it has taken to reach such stage.Enzymes

Conjugated enzymes consist of two components. The non-protein component is known as the cofactor or prosthetic group. This component of protein is required for catalytic activity.
Elimination of this non-protein part from conjugated enzymes leaves only the proteinaceous part which is known as apoenzyme. This component of enzymes is biologically inactive.

What is the frequency of the a1a2 genotype in a population composed of 20 a1a1 individuals, 80 a1a2 individuals, and 100 a2a2 individuals?.
Answers
The frequency of a1a2 genotype in the population will be 0.4.
Frequency can be defined as the rate of repetition of an event or outcome. To calculate the frequency, the number of desired outcome is divided by the total number of possible outcomes.
According to the question,
a1a1 individuals = 20; a1a2 individuals = 80 and a2a2 individuals = 100
Therefore, the total number of individuals in the population = 20 + 80 + 100 = 200
Here the desired outcome is a1a2, which is equal to 80 and the total number of outcomes = 200.
Therefore, frequency of a1a2 individuals = [tex]\frac{80}{200}[/tex] = 0.4

Different arrangements and structures of flagella contribute to changes in speed and direction when necessary. Motility relates to flagellation as:
Polar flagella (in any one or both the poles of the bacterium) makes the organism move very quickly in a particular direction.Peritrichous flagella (present all over the cell) helps the organism in rotation and tumbling.Amphitrichous flagella ( present in bulk at both the ends) move the organism slowly as these flagella work alternately and hence stop periodically to change directions).Flagella is a hair like structure present in both prokaryotic as well as eukaryotic cell.
