From your knowledge about the distribution of electrons in their shells and from the atomic number (in parentheses), indicate the most likely charge on the ion when this atom forms an ion. (Remember the 2-8-18 shell distribution.) Hydrogen (1)

Answers

Answer 1
Answer:

The right answer is C. +1 (for hydrogen).

The hydrogen atom can lose its single electron to give the H + ion, commonly referred to as the proton name. In fact, the atom which has lost its only electron is reduced to its nucleus, and in the case of the most abundant isotope 1H, this nucleus consists only of a proton. This name is not strictly correct if one takes into account the presence, although discrete (less than 0.02%), of the other isotopes. The name hydron is more general (we also say hydrogen ion, despite the possible confusion with the H- anion).

Answer 2
Answer:

Answer:

C. +1 (for hydrogen).

What enzyme is used to make radioactive labeled DNA

Answers

Answer:

Explanation:

DNA polymerase

Use of radioactive deoxyribonucleotides as raw material for DNA synthesis makes DNA polymerase to use these radioactively labeled dNTPs to make new DNA strands. Hence, DNA polymerase enzyme can make radioactively labeled DNA by using radioactive deoxyribonucleotides as raw material.

Describe two examples of how an understanding of genetics is making new fields of health care(treatment or diagnosis)possible?

Answers

Answer:

Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.

Increasing understanding of genetics help in making new fields of health care, for example,  

  • Gene therapy helps in treating various genetic diseases such as cystic fibrosis et cetera.
  • Molecular genetics help in the development of more precise methods for diagnosis such as ELISA.
  • Pedigree analysis and karyotypes help in early detection of possible hereditary diseases.
  • DNA fingerprinting helps in detecting criminal suspects, paternity test, identification of dead organism et cetera.
Genome sequencing allows specialized cancer treatments, and research regarding genetic markers can help to predict an individual's likelihood of having diseases such as heart disease or diabetes.

What is reason for binomial nomenclature?

Answers

Answer:

allow people throughout the world to communicate unambiguously about animal species.

Explanation:

Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.

According to Kübler-Ross, the first reactive phase in a person confronting death is

Answers

Answer: There are many theories regarding the concept of death. By studying the theory of Kubler Ross we came to know that the first reactive phase in a person who is confronting death is deniel and isolation. It is used by almost all the patients. It is usually a temporary shock response to some kind of a bad news. The isolation  in the patient can be created by any of his family members or friends. This condition arises in the patient when he or she thinks that they can no longer cope up with the situation and will die.





Final answer:

The first stage of Elisabeth Kübler-Ross's model for confronting death is termed 'Denial', where the individual initially reacts with disbelief about their fatal condition. This serves as a temporary buffer to slowly absorb the grave news.

Explanation:

According to the model conceived by Dr. Elisabeth Kübler-Ross, the first reactive phase that a person is suggested to experience when confronting death is Denial. Denial represents a person's initial shock or disbelief that they are dying. In this stage, it's common for individuals to think there must be some mistake in their diagnosis.

They might believe the tests were wrong, the physicians are mistaken, or even that they will wake up and realize it's all been a dream. Even though denial is considered an unhealthy coping mechanism in the long term, it serves a very important brief protective function in the initial stage, allowing individuals to absorb the news of their mortality gradually.

In the cells of the human body, oxygen moleculesare used directly in a process that
(1) releases energy
(2) digests fats
(3) synthesizes carbohydrate molecules
(4) alters the genetic traits of the cell

Answers

The answer is (1) releases energy. In the cells of the human body, oxygen molecules are used directly in a process of cellular respiration during which energy is released. In cellular respiration, glucose and oxygen yield carbon dioxide and water and energy is released in the form of adenosine triphosphate: C₆H₁₂O₆ (glucose) + O₂ (oxygen) → H₂O (water) + CO₂ (carbon dioxide) + ATP (adenosine triphosphate).
