<span>The energy to this reaction can be provided by adding a catalyst enzyme : DNA polymerase. Energy is released when this enzyme cuts off 2 phosphate groups from the end of the nucelotide. This energy is sufficient to link the nucleotide to the DNA.</span>
Answer: Autocrine signal, paracrine signal and endocrine signal.
Explanation:
Testosterone is an example of hormone which shows its effect on different locations of the cells.
The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.
Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.
The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.
All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.
Unregulated and uncontrolled cell growth is the most common simple definition of cancer. Because of the many types of cancers and a huge range of possible symptoms, treatments are also very diverse. Type of treatment also depends on cancer stage at diagnosis, and the patient's overall health. Some forms of treatment:
• Chemotherapy-usage of chemicals (medications) that target rapidly uncontrolled dividing cells,
• Hormone therapy
• Immunotherapy-usage of the medications that boost the immune system
• Radiation therapy-usage of radiation to kill the cancer cells
• Surgery
• New approaches such as stem cell therapy or personalized therapy.

<span>Answer:
Parabiosis is an effective way to evaluate hormone function because it permits the exchange of only long-lived molecules (such as hormones) between the two joined individuals. Thus, the glucose levels of each mouse will stay the same, but the hormone levels will not. The db mutant's hormone level will decrease, and the wild type's hormone level will increase.
Coleman's goal was to determine if the ob and db genes function in the hormonal regulation of appetite and body fat. In this experiment, if both appetite-suppressing hormone and glucose were exchanged, it would be impossible to determine whether any weight changes in the mice were caused by the transfer of hormone or the transfer of glucose from one mouse to the other. For example, an increase in hormone level (and thus greater appetite suppression) could lead to weight loss, as could a decrease in glucose level. On the other hand, a decrease in hormone level or an increase in glucose level could lead to weight gain.</span>
