Answer: Gaps in the fossil record. Because not all animals have bodies that easily fossilize, the fossil record is considered incomplete.

Explanation:

The fossil record is in fact incomplete, preserved fossils represent a biased sample, fossil discovery is not random and those found reveal only partial information about the original organisms. Nucleic acids, for example, have a very limited survival time.

Under normal conditions of fossilization, only about 15% of organisms are probably conserved. The fossil record is influenced in favor of those animals and plants with hard, mineralized shells, skeletons or cuticles, and towards those that live in marine environments.

Answer:

The possible fate of the cell that it may turn cancerous.

Explanation:

The cells present in the body generally work in harmony. However, if a cell attains a mutation, it can make it proliferate in the case when it should not do, and make it thrive in the case when other cells are dying. Due to proliferation, the unusual cell produces more abnormal cells also known as cancerous cells. These cancerous cells become more favorable in comparison to the normal cells due to the phenomenon of natural selection. These cells eventually result in a lethal form of tumors.  

In the normal cells, the destructed gene or the damaged cells get repaired easily, in case if the damage is worse the cell dies. A protein known as p53 helps in repairing damaged cells or kills them if the damage is too severe. But in the case of cancer cells, the p53 protein does not work appropriately as they possess a mutated or changed form of p53 protein. Thus, in the case of cancerous cells, the rate of repair lags behind the rate of mutation, which makes the cancer cells thrive and increase in numbers resulting in further destruction.

Answer:

Enrichment helps satisfy both the physical and psychological needs of animals and allows them to make choices. Thus, animal enrichment creates a win-win-win situation for the animals, visitors and keepers! In the wild, animals must find food, defend territories, escape predators and build homes.

Which of the following is most consistent with the modern theory of evolution​
Alecsey [184]

The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.

Explanation:

The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.

Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
