Answer:
High mass stars have very high-core temperatures, crushing stellar-core pressures, and are very big and very bright.
Explanation:
Answer:
crossing over
Explanation:
This occurs between prophase 1 and metaphase 1.
The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

The two types of limiting factors are Density - dependent and Density independence. <span> Density-dependent limiting determinants depends on the community size; the comprehensive population, the consequential influence a density-dependent limiting agent will ought. Density-independent limiting determinant does not really depend on inhabitants dimension, alternatively they change all populations proportionately. </span>
