When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.
- It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
- An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
- An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
- Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.

The cells show characteristics of tumors.
Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.
<span>
A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.</span>
The correct answer is <span>d.directly to the deceased.
It is believed that at this period, just after passing away, the soul is open to new knowledge and understanding, and the soul can understand life and its purpose and things like that if the priest is talking to it because it teaches it how to do that.</span><span />
High quantities of nutrients in water from industrial crop fertilizers and animal waste cause excessive aquatic plant growth — a process known as “eutrophication,” which, in turn, causes “hypoxia,” or water that is low in oxygen. Harmful algal blooms (or HABs) occur when aquatic algae grow rapidly out of control.
Answer:It predicts and lists all chemical elements in the universe. What do electrons in the same shell have in common? They all have the same amount of energy. ... They cannot be broken apart without losing their chemical properties.
Explanation:I took a quiz on it
