Why should/shouldn't Pluto be reclassified as a planet?​
Scorpion4ik [409]

Answer:

(This could be opinion based, but ok.)

Explanation:

should:Pluto was known as a planet for 75 years. This means that most people already knew it as a planet, and would be extremely confused. All of the books about planets would be inaccurate and changed. Not all people can access brand new books, leading to inaccurate information.

shouldn't: The same reason that it was unclassified as a planet. It does not adhere to all of the rules of being a planet. It is not completely round and does not have a round orbit around the sun. Pluto does not have every requirement to be a real planet, and therefor, it would be incorrect to have it classified wrongly.

Label all of the components of this DNA structure with the following terms: Phosphate sugar backbone, nitrogenous base, hydrogen
Hunter-Best [27]

Answer:

Phosphate sugar backbone:                                                                                              

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

Nitrogenous base:                                                                                              

Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.

Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.

Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.

The nitrogen bases are helped together through hydrogen bonds.

Hydrogen Bonds:

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

______ is a defense mechanism that occurs when group members believe the logical, but false explanation of their behavior.
Ede4ka [16]

Answer:

The correct answer is- Rationalization

Explanation:

Rationalization is a defense mechanism that involves the action to justify their unobvious behaviors by logical reasons to avoid true explanation. For example, if an employee is not given promotion might rationalize his disappointment by saying that he does not want extra responsibilities.

Rationalization may help the person to avoid guilt and maintain self-respect when he has done something wrong. Many times rationalization is not harmful to the person but if it becomes a habit of a person it can cause a problem for him and others. Therefore the correct answer is rationalization.

Several members of the same family were diagnosed with he same kind of cancer when they were unusually young. Which one of the f
Verdich [7]

Answer:

(c) Inherited a mutation in a gene required for mismatch repair

Explanation:

Gene mutations are occasional changes that occur in genes, that is, the procedure by which a gene undergoes a structural change. Mutations involve the addition, deletion or substitution of one or a few nucleotides of the DNA strand. Mutation provides the emergence of new forms of a gene and, consequently, is responsible for gene variability.

It is common for several members of the same family to have the same genetic mutations, as the gene affected by the mutation may condition a trait that DNA cannot repair. An example of this is the family shown in the question above, where several people were diagnosed with the same type of cancer while still young. What probably happened in this family was that people diagnosed with cancer inherited a mutation in a gene needed to repair incompatibility.
