Answer:

The physical conditions are necessary for nuclear fusion and formation of stars are given below.

Explanation:

Nuclear fusion emitted high amount of heat energy which increases the temperature of the surrounding environment while formation of stars absorb heat energy and finally lower the temperature. The force of gravitational attraction is lower in nuclear fusion while the force of gravitational attraction becomes higher in formation of stars. Nuclear fusion does not promote stellar formation while formation of stars  promotes stellar formation.

What would the growth equation look like for sessile populations (Sessile populations can’t move, like a barnacle)?
pantera1 [17]

Answer:

births - deaths = growth

Explanation:

(births - deaths) + (immigrants - emmigrants) is what you would normally use to calculate the growth of a population, but because they can't move, you can cut out the immigrant and emmigrant part of the equation.

Name the three carbon compound converted during respiration? How is it converted to products in absence, presence, and lack of o
ValentinkaMS [17]

The answer is pyruvate. In the absence of oxygen in anaerobic respiration, the pyruvate is converted to lactic acid in animals and ethanol in plants. However, in the presence of oxygen, the pyruvate enters the Krebs cycle after being converted to Acetyl CoA. Pyruvate is an intermediate product of glycolysis.

Transcription chain elongation is thought to generate ____ supercoils ahead of the transcription bubble and _____ supercoils beh
frosja888 [35]

Answer:

a. positive; negative

Explanation:

Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.

The transcription process is divided into three steps: initiation, stretching and termination

During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.

During this process, it is believed that positive supercoils  are generated ahead of the transcription bubble and  and the negative supercoils behind it.

Explain why it is important for daughter cells to have a full set of chromosomes. Use complete sentences.
Leya [2.2K]
In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.
