Characteristics of life
is the sum of all anabolic and catabolic reactions that take place in the body.
What is metabolism?
is the smallest independently functioning unit of a living organism
What is a cell?
separates the inner contents of a cell from its external environment
What is the cel membrane or plasma membrane?
is an organelle that contains enzymes that break down and digest unneeded cellular components, such as a damaged organelle in a process called autophagy
Changes in an organism’s internal environment, such as increased body temperature, can cause sweating and the dilation of blood vessels in the skin in order to decrease body temperature
What is responsiveness?
What are the levels of cellular organization?
What are subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms?
the jelly-like substance within the cell, provides the fluid medium necessary for biochemical reactions and is mostly composed of water.
___________is an organelle that serves as the site of ____________ synthesis, and it is composed of two subunits.
What is a ribosome and protein?
The process of cell differentiation, in which unspecialized cells become specialized in structure and function to perform certain tasks in the body.
What is Development?
is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function.
What are Tissue?
Most membranous organelles found in a human cell together form a system
What is the endomembrane system?
The components of the endomembrane system include.
What are the nuclear envelope, endoplasmic reticulum, Golgi apparatus, vesicles, and plasma membrane?
___________the process by which larger, more complex substances are broken down into smaller, simpler molecules.
What is Catabolism?
Two or more atoms combine to form a_________
What is a molecule?
•a system of channels that is continuous with the nuclear membrane (or “envelope”) covering the nucleus and composed of the same lipid bilayer material.
What is the endoplasmic reticulum?
The inner membrane is highly folded into winding structures with a great deal of surface area, called cristae.
What are mitochondria?
Taking in materials from their external environment and expelling waste products out into their external environment.
What is exchange of materials?
Adult and children would be considered this.
What are organismal?
Responsible for sorting, modifying, and shipping off the products that come from the rough ER, much like a post office.
what is the Golgi apparatus?
some cells in the body, such as muscle cells, contain more than one nucleus which is known as_________
Whatr is multinucleated?
