Answer:
Option A (dark energy) is the right answer.
Explanation:
- A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
- Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.
Some other three choices have no relation to the particular situation. Thus option A would be the right solution.
Answer:
Carbon dioxide
Explanation:. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
Answer:
Signal transduction
Explanation:
A signal molecule binds to a receptor.
A conformational change in the signal-receptor complex activates an enzyme.
Second messenger molecules are released.
Protein kinases are activated.
Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.
Answer:
músculo cardíaco
Explanation:
Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.
