The energy for ATP synthesis comes from organic molecules (such as carbohydrates), or from sunlight, or from inorganic electron donors. We can classify organisms according to their source of energy and organic carbon:
<span><span>heterotrophs – get energy and organic carbon from metabolism of pre-existing organic compounds (food)</span><span>photoautotrophs – use energy from sunlight to make ATP and their own organic carbon compounds from carbon dioxide chemoautotrophs</span><span> – use energy from inorganic chemicals to make ATP and their own organic carbon compounds from carbon dioxide</span></span>
Metabolic pathways carry out reactions that capture energy from these various sources (organic compounds, sunlight or chemicals) and couple them to synthesis of ATP from ADP.
Answer:
The correct answer is - culture shock.
Explanation:
Culture shock is an experience a person or anthropologist may have when one transfer to a cultural environment that is distinct or vary from their own culture.
The anthropologist in this question is experiencing alienation feeling, trivial when he move to new field site, he is experiencing cultural shock. It is also cause disorientation a person.
Thus, the correct answer is - culture shock.
It is believed that the tilapia fish was introduced into the mangrove system by escaping from fisheries and aquariums by accident, but this species is also used to control the population of mosquitos to prevent outbreaks of malaria and other invasive species on which they feed.
The tilapia are highly tolerant and easily adaptable to different conditions in the mangrove ecosystem and they are highly efficient predators. This often makes them more successful in the environments where they are introduced than the indigenous species, which results in disruption of the food chain.
The negative human impact on mangroves disrupts the balance in the mangrove ecosystems, weakening the populations of different species that originate from mangrove forests. This leaves more space and resources to be exploited by the tilapia.
The strategies to control tilapia in mangrove ecosystems focus on restoring the habitat and strengthening the populations of indigenous species while decreasing the numbers of tilapia.
The species can be eradicated by selective overfishing of the species or by introducing another species into the habitat which is a natural enemy of the tilapia.
Answer: Option C
Explanation:
All the communicable diseases are contagious. They spread from one person to another person.
They are transmitted by the common routines that we do in our daily life like sharing some stuffs, sharing the towels, using smart phones of some other person, sneezing, coughing, et cetera.
These diseases are common cold, flu which is transferred from one person to another.
