Anatomical Principles & Cell Basics

The correct answer is cranial because the question states that Maurice has a bad headache, which indicates that the pain is localized in the head. The cranial cavity houses the brain and is responsible for protecting it, so any issues or discomfort in this area would affect the head.

The correct answer is the immune system. When Antoinetta contracts a viral infection, her immune system responds to fight off the infection. The immune system is responsible for identifying and destroying pathogens, such as viruses, to protect the body from illness and infection. It does this through various mechanisms, including the production of antibodies and activation of immune cells. In this case, the immune system would recognize the viral infection and initiate an immune response to eliminate the virus from Antoinetta's body.

The nervous system is responsible for receiving messages from the environment and coordinating the body's response to those messages. It consists of the brain, spinal cord, and nerves, which work together to transmit electrical signals throughout the body. This allows us to sense our surroundings, process information, and initiate appropriate actions or responses. The skeletal system provides support and protection for the body, the respiratory system is responsible for breathing and oxygen exchange, and the immune system defends against foreign invaders. However, neither of these systems directly facilitate the reception and response to messages like the nervous system does.

The reproductive system is responsible for combining egg and sperm cells to create new life. It includes organs such as the ovaries, testes, uterus, and fallopian tubes. These organs work together to produce and transport gametes (egg and sperm cells), facilitate fertilization, and support the development of a fetus. The cardiovascular system is responsible for circulating blood throughout the body, the respiratory system is responsible for breathing and exchanging gases, and the nervous system is responsible for transmitting signals and coordinating bodily functions. None of these systems are directly involved in the process of reproduction.

The plane shown below is the transverse plane. This plane divides the body into superior and inferior portions, or in other words, it separates the body into upper and lower sections. It is also known as the horizontal plane because it is parallel to the ground when the body is in an anatomical position.

Proteins provide structure for the hair, muscle, skin, and nails. Proteins are made up of amino acids and are essential for the growth, repair, and maintenance of tissues in the body. They form the building blocks of cells and are responsible for the structure and function of various body parts, including hair, muscle, skin, and nails. Therefore, protein is the correct answer.

The organ system shown in the image is the digestive system. This system is responsible for breaking down food into nutrients that can be absorbed by the body. It includes organs such as the mouth, esophagus, stomach, small intestine, and large intestine. The digestive system plays a crucial role in the digestion and absorption of nutrients, as well as the elimination of waste products.

In this scenario, Deonsae is experiencing a heart attack, which is a medical emergency involving the heart. The thoracic cavity is the correct answer because it houses the heart, lungs, and other vital organs in the chest region. Accessing the thoracic cavity would allow medical professionals to reach the heart and perform the necessary emergency procedure to address the heart attack.

The correct answer is thoracic because the lungs are located within the thoracic cavity, which is also known as the chest cavity. This cavity is surrounded by the rib cage and contains vital organs such as the heart and lungs. The thoracic cavity is separated from the abdominal cavity by the diaphragm.

Mr. Carter's trouble with filtering waste from his blood indicates a dysfunction in the urinary system. The urinary system is responsible for filtering waste products from the blood and eliminating them from the body through urine. Dialysis treatment is a medical procedure that helps to perform the function of the kidneys when they are unable to do so effectively. Therefore, the correct answer is the urinary system.

The arrow is pointing towards the inferior end of the patient. This means that it is indicating the lower or lowermost part of the patient's body.

The type of organic molecule that makes up our DNA is called nucleic acids. Nucleic acids are large biomolecules that store and transmit genetic information. DNA, or deoxyribonucleic acid, is a type of nucleic acid that contains the instructions for the development and functioning of all living organisms. It is composed of two strands of nucleotides that are held together by hydrogen bonds. Nucleic acids are essential for the replication and expression of genetic information, making them crucial for the inheritance of traits and the functioning of cells.

A cell is considered the basic unit of life because it is the smallest structural and functional unit that can carry out all the necessary processes of life, such as metabolism, growth, and reproduction. Cells are the building blocks of all living organisms and can exist as single-celled organisms or as part of multicellular organisms. They contain genetic material, have a cell membrane that regulates the passage of substances, and have specialized structures called organelles that perform specific functions. Overall, cells are fundamental to the existence and functioning of all living things.

Meiosis is a type of cell division that specifically occurs in the reproductive cells, also known as gametes. It is responsible for creating sex cells, such as sperm and eggs, which are essential for sexual reproduction. During meiosis, the number of chromosomes in the cells is halved, resulting in genetic diversity in offspring. This process ensures that the resulting sex cells have the correct number of chromosomes to combine during fertilization and produce a genetically unique individual.

The plane shown in the image is the sagittal plane. This plane divides the body into left and right halves, allowing for a side view of the structures. It is perpendicular to both the frontal and transverse planes.

The arrow is going from the anterior to the posterior of the patient.

Mitosis is a type of cell division that occurs in somatic cells, which are responsible for the growth and repair of the body. This process results in the formation of two identical daughter cells, each containing the same number of chromosomes as the parent cell. Therefore, the correct answer is somatic cells for growth and repair.

Meiosis is the correct answer because it is the type of cell division that creates new sperm cells. During meiosis, a diploid cell undergoes two rounds of division to produce four haploid cells, each containing half the number of chromosomes as the original cell. This process is essential for sexual reproduction and ensures genetic diversity in offspring. Mitosis, on the other hand, is a type of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell.

An organ is a group of tissues that work together to perform a specific function in the body. Unlike a single cell or molecule, an organ is made up of different types of tissues that collaborate to carry out complex tasks. Therefore, an organ is the most appropriate choice for a group of tissues.

The plane shown in the image is the frontal plane. The frontal plane divides the body into front and back halves, also known as anterior and posterior. This plane is perpendicular to both the sagittal and transverse planes.

This food is high in lipids, which are organic molecules that are commonly known as fats. Lipids are an essential component of our diet and provide a concentrated source of energy. They also play important roles in cell structure, insulation, and the absorption of fat-soluble vitamins.

Down's Syndrome is caused by an extra copy of chromosome 21, also known as trisomy 21. This occurs when one of the parent's sex cells (either the egg or the sperm) undergoes a mistake during meiosis, resulting in an extra copy of chromosome 21. This error in chromosome segregation during meiosis is the most common cause of Down's Syndrome.

A healthy human sex cell, also known as a gamete, contains half the number of chromosomes compared to other cells in the body. This is because during sexual reproduction, the gametes from both parents combine to form a new individual with a complete set of chromosomes. In humans, the normal number of chromosomes in a somatic cell is 46, but in a sex cell, it is reduced to 23. This reduction ensures that when the gametes combine during fertilization, the resulting zygote will have the correct number of chromosomes for normal development.

Mitosis is the correct answer because it is the type of cell division that occurs in somatic cells to repair damaged tissues. In this case, Jaylin's muscle cells are undergoing mitosis to replace the damaged cells and heal the sprained ankle. Meiosis is not applicable in this scenario as it is the type of cell division that occurs in reproductive cells to produce gametes.

Fruits like oranges contain a lot of glucose, which is a type of carbohydrate. Carbohydrates are molecules that provide energy for our cells when broken down. Therefore, the correct answer is carbohydrate.

Lipids are organic molecules that store long-term energy for the body. They are a concentrated source of energy, providing more than double the amount of energy compared to carbohydrates and proteins. Lipids are stored in adipose tissue and can be broken down and used as fuel when the body needs energy. Therefore, lipids play a crucial role in energy storage and are an essential component of a balanced diet.

Mitosis is the process of cell division in which one cell divides into two identical daughter cells. When there is damage to the genes, it can lead to uncontrolled mitosis, causing cells to reproduce too quickly. This uncontrolled cell division can result in the formation of tumors, which is a characteristic feature of cancer. Therefore, the answer "mitosis is uncontrolled due to damage to the genes and cells are reproducing too fast" best explains what causes cancer.
