Olá!!! Bom vamos lá!
O nucleotídeo é constituído de um açúcar,um grupo fosfato e uma base nitrogenada. Nesse caso estamos falando de subunidade então podemos dizer que estamos falando do RNA ou DNA, logo, teremos a desoxirribose como açúcar.
Depois teremos um grupo fosfato e assim as bases nitrogenadas ( Guanina, Timina/Uracila, Citosina, Adenina) Sendo que C combina com G e A combina com T/U , vamos usar a base T quando for DNA, e quando for RNA vamos usar U. Por isso a resposta correta é a letra B!
Espero ter ajudado em algo!
B. Forces can act on object and cause motion .....
Food chains are for example something that another thing eats and it goes down to many different selections and starts off big and vies to small things
The type of joint that allows bones to move backward and forward in only one direction is the hinge joints. Ball and socket are the joints that allows movement in all directions. Gilding joints are type of joints that are the vertebral disks that allow twisting, turning, and sliding. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. They include the ankle, elbow and knee joints.
Answer: Cell with membrane potential have EXCITABILITY, thus, the correct option is C.
Explanation:
Membrane potential refers to the difference in electric potentials between the inside and the outside of the cell membranes of living organisms. This difference in electric potential give the cell membranes the ability to receive and to respond to stimuli, this ability is called excitability.
The central nervous system is responsible for processing stimuli information and sending out appropriate responses to different parts of the body including the muscles. The muscles tissues are able to respond to the directions of the nervous system to contract or to relax because of their ability to be excited due to the potential differences between the outer and the inner plasma membrane.
