Explanation:
Bohr's model of the atom states that electrons orbit an atom's nucleus in electron shells of increasing energy. ... Thomson's model, or the plum pudding model, it describes atoms as spheres of positively charged matter, in which electrons are embedded in
Answer:
on channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms. In multicellular organisms, cells send and receive chemical messages constantly to coordinate the actions of distant organs, tissues, and cells. Cells can receive a message, transfer the information across the plasma membrane, and then produce changes within the cell in response to the message. Single-celled organisms, like yeast and bacteria, communicate with each other to aid in mating and coordination. Cellular communication has developed as a means to communicate with the environment, produce biological changes, and, if necessary, ensure survival.
The cellular respiration happens in the mitochondria. During the cellular respiration, glucose and oxygen are the reactants during this process and the main product of this process is ATP, with waste products carbon dioxide and water. Therefore, the correct answer would be option B. O2 (oxygen) and C6H1206 (glucose).
The cells would be dividing all the time. Hope this helps
Answer;
-Cell
Explanation;
-The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Cells make up the smallest level of a living organism such as human beings and other living things.
-The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life. Some organisms, such as bacteria or yeast, are unicellular; consisting only of a single cell, while others, for instance, mammalians, are multicellular.
