Explain how a chromosome condenses at the beginning of mitosis

answer in explanation:

Explanation:

Chromosomes must condense at the beginning of mitosis so they can be separated, with relative ease, into equivalent halves. Chromosomes adopt a compact form to make them suitable for transport.

Condensation also organizes the DNA molecule in such a manner that the chance of the molecule being broken and/or lost is minimized. If the chromosome breaks in one way or another, mutations occur.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
