Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

Answers
The organism described that can cause illness and death in humans, reproduces asexually, and is among the simplest of living things, is a bacterium.
Bacteria are single-celled microorganisms that can be found in various environments, including soil. They are characterized by their simplicity of structure and lack of a nucleus or membrane-bound organelles.
Certain species of bacteria are pathogenic and have the ability to cause diseases in humans. Examples include bacteria like Escherichia coli (E. coli), Salmonella, and Staphylococcus aureus.
These bacteria can enter the human body through various means, such as contaminated food or water, and can cause a range of illnesses, from mild to severe, and even life-threatening conditions.
Bacteria have the ability to reproduce asexually through a process called binary fission. In this process, a single bacterium divides into two identical daughter cells, allowing for rapid multiplication of the population.
It is important to note that while bacteria can be harmful, many bacteria are beneficial or have neutral effects on humans and play crucial roles in various ecological processes and human health.

Answer:
The youngest Prime Minister to be appointed was William Pitt the Younger on 19 December 1783 at the age of 24 years, 6 months and 21 days.
Explanation:
William Pitt the Younger (28 May 1759 – 23 January 1806) was a prominent British Tory statesman of the late eighteenth and early nineteenth centuries. He became the youngest prime minister of Great Britain in 1783 at the age of 24 and the first prime minister of the United Kingdom of Great Britain and Ireland as of January 1801. He left office in March 1801, but served as prime minister again from 1804 until his death in 1806. He was also Chancellor of the Exchequer for all of his time as prime minister. He is known as "the Younger" to distinguish him from his father, William Pitt, 1st Earl of Chatham, who is customarily referred to as "William Pitt the Elder" (or less commonly, simply "Chatham") and had previously served as prime minister.

Answers
Sharon wants to conduct an experiment to determine if increasing the concentration of atmospheric carbon dioxide around a plant will affect the plant's rate of photosynthesis. The correct option is C 4-3-2-1 .
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. The word "photosynthesis" comes from the Greek words "light" and "putting together," and refers to the process of creating molecules of carbohydrates from carbon dioxide and water. These molecules, such as sugars and starches, are then stored with some of this chemical energy. [1] [2] [3] Photoautotrophs are creatures that perform photosynthesis, including most plants, algae, and cyanobacteria. The majority of the energy required for life on Earth is produced and maintained by photosynthesis, which is also substantially responsible for producing and maintaining the oxygen content of the atmosphere.
Even though various species perform photosynthesis in different ways, the process always starts when energy from light is absorbed by proteins called reaction centers that contain the colored pigments/chromophores green chlorophyll (and other colors). Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.

In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answers
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.

Cancer is one of the leading causes of death in our society. Cancer is a disease in which a
cell in the body loses its sensitivity to factors which regulate cell growth and division. The
cell begins to multiply without restriction, creating a growing mass called a tumor, which
interferes with the structure and functioning of the organ in which it is located.
Frequently, cancer cells become metastatic, meaning that they travel, settling in a number
of places and giving rise to secondary tumors. Much of medical research is devoted to
finding ways of preventing, controlling, and curing cancer.
Because of the metastatic trait of cancer cells, how can we judge a cancer treatment to be
effective?
A. if the highest possible levels of treatment have been used
B. if the complete tumor is removed
C. if the entire body has been proven free of tumors over a period of time

The corn cob would float partially submerged in the water.
Density of a fluid is defined as the ratio of mass of the fluid to the total volume of that fluid. The SI unit of Density is kilograms per cubic meter. We know the substance or the fluid having lower value of the density float on the fluid having higher value of the density.
We are provided with the data,
Density of corn on the cob = 721 kg/m³
Density of water = 1000 kg/m³
We can clearly see from the data of densities that the density of corn on the cob is less as compared to the density of water. So, the corn cob would float partially submerged in the water.

How to find speed velocity in 38 times 2 over 20
Answers
To find the speed velocity, divide the product of 38 and 2 by 20. The result is the speed velocity.
To find speed velocity, we need to divide the distance traveled by the time taken.
In this case, the distance traveled is 38 times 2, which equals 76 units. The time taken is 20 units.
To calculate speed velocity, we divide the distance (76 units) by the time (20 units).
Speed velocity = Distance/Time = 76 units / 20 units = 3.8 units per unit of time.
Therefore, the speed velocity in this scenario is 3.8 units per unit of time.
It's important to note that units were not specified in the question, so the units of measurement for distance and time are unknown.
The result can be interpreted as 3.8 units of distance covered per unit of time.
