Anatomy Test 1

Mitosis is the process of cell division where a single cell divides into two identical daughter cells. Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. Binary fission is a form of asexual reproduction used by prokaryotes while cytokinesis is the process of cytoplasmic division following the division of the nucleus.

Humans typically have 23 pairs of chromosomes, for a total of 46. Each parent contributes one set of 23 chromosomes, resulting in the offspring having a total of 46 chromosomes.

The phospholipid bi-layer of the cell membrane is responsible for repelling water and regulating what goes in and out of the cell.

The mid-sagittal plane divides the body into left and right halves, ensuring symmetry in terms of structure and organs. Frontal, Transverse, and Coronal planes do not guarantee symmetry in the body.

In anatomy, the opposite terms are used to describe the different directional locations within the body. Superior is opposite to Inferior, Posterior is opposite to Anterior, Dorsal is opposite to Ventral, and Superficial is opposite to Deep.

The Anterior/Ventral Cavity is made up of the Thoracic, Diaphragm, Abdominal, and Pelvic regions. The Cranial, Spinal, and Cardiac regions are not part of the Anterior/Ventral Cavity.

The Dorsal/Posterior Cavity is made up of the Cranial and Spinal Cavities, which house the brain and spinal cord respectively. The Thoracic, Abdominal, and Pelvic Cavities are part of the Ventral cavity.

The different types of muscle tissue are smooth, cardiac, and skeletal which collectively make up muscle tissue, also known as TONUS.

Muscle tissue is responsible for movement of the body due to its ability to contract and elongate. Nerve tissue transmits signals to and from different parts of the body, bone tissue provides structure and support, and epithelial tissue acts as a protective barrier.

Connective tissue is the most abundant and diverse tissue type in the human body, providing support, structure, and protection to various organs and systems. While muscle tissue, epithelial tissue, and nervous tissue are essential components as well, they are not as widespread or versatile as connective tissue.

Epithelial tissue is the correct answer as it is the type of tissue that covers the body's external surfaces and lines internal organs. Connective tissue, muscle tissue, and nervous tissue serve different functions in the body.

The correct answer includes epithelial, connective, nerve, and muscle tissues, which are the four main types of tissues in the human body.

The correct answer is cells because they are considered the basic structural and functional unit of living organisms.

The correct answer is 220, as there are approximately 200 different types of cells and 20 different types of tissues in the human body.

Organs with similar functions come together to form an organ system, allowing them to work together efficiently.

The term 'organ level' refers to structures in biology that are composed of 2 or more specialized groups of tissue. At the organ level, these tissues work together to carry out specific functions.

The tissue level of organization in the body is where groups of similar cells come together to perform a specific function, which is more specialized and specific than the cellular level but less complex than the organ and system levels.

Cells are the basic structural, functional, and biological units that perform vital functions in living organisms. Organs and tissues are made up of cells, and enzymes are molecules that catalyze biochemical reactions in cells.

The cellular level refers to the level of organization in which cells are the basic unit of structure and function. At this level, cells contain specialized structures known as organelles. The molecular level focuses on the interactions between molecules within a cell. The tissue level involves groups of cells working together to perform a specific function. The organ level consists of different types of tissues working together to form structures with specific functions.

The correct answer is organism as it is the highest level of organization in living beings, comprising multiple organ systems.

The correct answer refers to the chemical composition of the body and how its elements come together at this specific level.

The correct levels of organization in living organisms are hierarchical, starting from the basic building blocks of chemicals all the way up to the complete organism.

Physiology is the study of how living organisms function, while anatomy focuses on the structure of organisms. Botany is the study of plants, and zoology is the study of animals.

Anatomy specifically focuses on the physical structure of organisms, rather than their functions, genetics, or ecological relationships.

Homeostasis refers to the body's ability to regulate and maintain a stable internal environment. Equilibrium is a state of balance but does not specifically refer to the body's internal environment. Metabolism is the process by which the body converts food and other substances into energy. Resilience is the ability to bounce back or recover from challenges.

The correct answer includes the basic essentials for the human body to function properly and survive. Shelter, sleep, and exercise are important for well-being but not considered as fundamental bodily needs.

Ribosomes are the cellular organelles responsible for protein synthesis, both for internal use within the cell and for export outside of the cell. Lysosomes are responsible for breaking down cellular waste, mitochondria are the powerhouse of the cell producing energy, and endoplasmic reticulum is involved in protein and lipid synthesis.

The nucleus is known as the control center of the cell as it houses DNA and directs nearly all metabolic activities.
