Answer:
mutated dna
Explanation:
there would be either be dna substitutions, deletions or insertions. substitution simply changes the letter. deletion gets rid of a letter. insertion adds another letter.
The process that would occur is called ecological succession. This describes the process of life re-colonising a previously disturbed area. In the beginning, a few hardy and fast-growing pioneering plants, usually weeds, will colonise the area. Subsequently, the community of plants inhabiting the area will become increasingly complex over time until an equilibrium is achieved.

Answer:
Immortal cell line
Explanation:
An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular operation and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro
Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology.
Options:
indirect
limited
direct
unimportant
Answer:
direct
Explanation:
Chronic stress is constant exposure of the body to stressors over a long period of time which involves response of the endocrine system over these periods. Overtime, the body wears and tear which is caused by the effects of chronic stress. This in the long run can result into heart disease, infections etc. Heart attack suffered by Jose can be considered to be a direct effect of chronic stress.
