Answer:
In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.
In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.
In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.
In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.
Apparently it is ATP as deduced from the last line of text and no model to refer to.
It is a study of ECOSYSTEM and known as ECOLOGY......
I believe that the correct diagnosis code is N13.30.
Diagnostic coding is the translation of written descriptions of diseases, illnesses and injuries into codes from a particular classification. These codes are used as part of the clinical coding process alongside intervention codes. N13.30 is a billable ICD code used to specify a diagnosis of unspecified hydronephrosis.
Answer:
The correct answer is - A) nuclear.
Explanation:
Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.
Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.
