Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.
The answer to this quietion is a
Answer:
C) in the second condition more words are recalled
Explanation:
In the second coding, the research participants' memory is helped, when some words from the list are cited. This can cause the participants to remember a greater amount of words than the amount that was remembered in the first condition. This is because in the first condition the participants had no help to quote the memorized words, having to rely on only the own memory.
Booker T. Washington and W.E.B. DuBois were two important leaders of the Black community in the United States. However, they each had very different opinions about the role of the African community, and on how equality could be achieved.
Booker T. Washington believed that the Black community needed to adopt a philosophy of self-help, racial solidarity and accomodation. He believed that African Americans had the duty to educate themselves and improve their livelihood in order to be taken seriously by white Americans. On the other hand, W.E.B. DuBois believed that this approach only put an extra burden on black people, while ignoring the responsibilities of whites. He argued that social change had to come through political change, and advocated political action.
I believe that their differences were as substantial as the friction between their followers. The two men had very different opinions about race and advancement. Moreover, I believe that the opinions of Booker T. Washington were more suited to the temper of the times as he took a more positive view of white people and a more negative view of conflict and political activism.
