Biology

B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.

The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.

Will partial budgets ever contain some fixed ownership costs
madam [21]

<span>Yes, partial budgets MAY SOMETIMES contain some fixed ownership costs depending on whether the proposed change includes any change in capital assets owned (i.e. the purchase or sale of capital assets). If any change in capital assets is included in the proposed change, then fixed ownership cost will change, and this should reflect on the partial budget.</span>

experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domain
puteri [66]

The question is incomplete as it lacks the multiple options. The multiple options are as follows:

a. Across the three domains, all organisms depend solely on the process of anaerobic respiration for ATP production .

b. Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life .

c. The existence of glycolysis as an energy-releasing process in all organisms suggests that convergent evolution occurred .

d. All organisms carry out glycolysis in mitochondria.

Answer:

Option (b).

Explanation:

The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more closely related with each other than the prokarya.

The glycolysis is the process of breakdown of glucose molecule to generate ATP. The glycolysis is the most common process of the generation of the ATP are present in almost all the organisms whether the organisms is ancestral or modern.  

Thus, the correct answer is option (b).
