Answers
Answer:
Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. kills fish from oxygen depletions can range from “partial” to “total”. In a partial kill the dissolved oxygen level gets low enough to suffocate sensitive species and large fish, but many small fish and hardy species survive.

Answers
Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.
The antibiotic rifampicin blocks transcription in many bacteria. In the presence of the antibiotic, adding sigma factor has no stimulating effect on RNA synthesis. A footprinting experiment on a rifamycin treated sample shows that the polymerase remains located at the promoter site in the presence of eNTPs and Mg2 ion. What step of transcription is rifamycin likely to block
Answers
Answer:
transcription initiation
Explanation:
Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:
1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.
2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence
3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).
In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.

how is carbon captured and stored by organisms? how is carbon passed through the ecosystem? how is carbon returned to the ecosystem?
Answers
Explanation:
i dont.know im in that qt
Carbon enters all food webs, both terrestrial and aquatic, through autotrophs, or self-feeders. Almost all of these autotrophs are photosynthesizers, such as plants or algae. Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose.

2. How much is the average temperature at depth of 10 km of earth surface?
A) 200 °C
C) 650°C
B) 900°C
D) 20°C
Answers
Answer is 200 o c.
The average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.
What is the average temperature?An average temperature may be defined as the annual mean temperature of any geographical location which is estimated approximately by the average temperature of the maxima and minima for the warmest and coldest months of the year.
It is the principle that the increase in the depth below the surface of the earth ultimately leads to the rising of average temperature. This is due to the process of apparent heat.
It may be possible that higher or lower temperatures also occur. but the average temperature at depth of 10 km of earth surface should approximately remain 200°C. It is a factual type of question.
Therefore, the average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.
