The end result of metabolism is a cellular energy unit called
stepladder [879]


The best answer is ATP (Adenosine triphosphate).

Metabolism is a term referring to the overall processes by which  energy is obtained by an organism. In man it begins with the digestion process, and ends with cellular respiration.

Food molecules are broken down into their monomer units through the digestive process. Carbohydrates are broken into glucose units. Glucose is taken in by cells and used in cellular respiration to produce ATP, which is the form of energy that cells use.

Cellular respiration involves three stages namely glycolysis , Krebs cycle and electron transport chain.  From one molecule of glucose, the number of ATP molecules generated through cellular respiration  is 36 to 38 molecules.

How many different combinations of chromatids are possible during the early phases of anaphase in meiosis II
Ket [755]

Answer:

Explanation:) In mitosis, two genetically identical daughter cells are produced. Thus, the only possible combination of chromosomes is C1/C2/M1/M2/S1/S2 since all genetic material is inherited. b) The first meiotic division serves to split homologous pairs into two different cells, which are now haploid. There are 8 possible combinations of chromosomes (2 chromosomes for each homologous pair). For instance, a cell at this stage could inherit C1/M1/S1, or C2/M1/S1, or C1/M2/S1, etc. c) The same 8 combinations as above. The second meiotic division splits double-stranded chromosomes of each of these haploid cells into two daughter cells each so that only single-stranded chromosomes remain. Since no crossing over...
