The most common example that determines the similarities in anatomical features among organisms is the bone structure, commonly used in comparative anatomy. For example, the forelimbs or appendages of bats, humans, cats and whales have the same basic parts but they differ in function. Fins of whales and wings of bats have the same skeletal parts, but fin is used for swimming while wing is for flight. These structures could be termed as homologous, analogous, or homoplastic. However, recent developments have been made than just basing to the skeleton - the main reason why we have comparative genomics today.

mihalych1998 [28]

Answer:

B) expression of inappropriate gene products

Explanation:

Most of the cancers are caused when a normal gene that code for one or other proteins involved in the regulation of the cell cycle is mutated. The mutated gene may cause the production of the faulty gene products. For example, the overproduction of products of the protooncogene that push cells through the cell cycle leads to tumor formation. Likewise, when the tumor suppressor genes are not able to produce enough product to prevent progression through the cell cycle, cancer may develop.

<u>Answer:</u> Option D

<u>Explanation:</u>

The roots of achieving unexpected results lie or depend on scientific methods used and analysis of data performed for acquiring results. Therefore when experiment results into unexpected readings researcher need to give a review of entire method and analysis.

Although rest other points like publication of results, discussing with friends and family members or removal of inconsistent data may or may not help depends upon conditions but reviewing helps as observed in many cases , because one must have performed unintentionally or intentionally an error while going through methods.
