Answer:
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
Explanation:
Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.
True - a homogenous mixtures is a mixture that has the same amount of solute.
Answer:
In my opinion I think its B. Hypocenter
Sorry if wrong
Answer:
Based on the data presented, PLASTIC
bags have less impact on Earth’s resources. Even though PAPER
bags have less impact on organisms in the oceans, the production of PAPER
bags uses more of Earth’s materials and releases more carbon into the atmosphere.

Answer:
La genética ayuda a explicar: Lo que nos hace únicos. Por qué los miembros de la familia tienen rasgos en común. Por qué algunas enfermedades, como la diabetes o el cáncer, vienen de familia, La genética médica es una especialidad médica que trata con el diagnóstico y manejo de las enfermedades hereditarias. La finalidad de esta especialidad es brindar una medicina personalizada al paciente y por ende en algunos casos, tratamientos personalizados,los científicos pueden hacer ciertas combinaciones entre genes de diferentes especies, para así solucionar problemas y mejorar el rendimiento económico-comercial de las explotaciones. Se pueden buscar curas a enfermedades genéticas para que las nuevas generaciones nazcan más sanas.
