Answer:
esta es una expresión de admiración ante la belleza de los mecanismos evolutivos
Explanation:
El concepto de evolución como mecanismos naturales que está actualmente en boga fue originalmente planteado por Charles Darwin en su celebre publicación "El origen de las especies" (1859). La teoría de la evolución de Darwin está basada en la idea que las especies cambian constantemente con el tiempo a través del proceso de selección natural. Este mecanismo es responsable de la inmensa biodiversidad biológica observada en la naturaleza, la cual incluye la evolución de las especies, poblaciones y organismos individuales. Desde una perspectiva biológica, es imposible no quedar fascinado ante la naturaleza y contemplación de los procesos evolutivos.
Answer:
Smooth and cardiac
Explanation:
Smooth and cardiac muscles are both involuntary.
This means we do not consciously control them. Smooth muscles are found, for example, in the esophagus, and small intestine. The cardiac muscles are found in the heart.
The skeletal muscles are those that we control consciously, such as the muscles for moving our arms and legs.
Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
The segments of DNA that code for specific traits are called genes
Available oxygen
Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.
