Answer: A Fixed Action Pattern

Explanation:

A fixed action pattern is an ethological term and off course a natural activity pattern that causes animals to act in a specific behavior pattern distinctive to their species. It is a pattern that is relatively unchangeable within the species and usually ends even when it is interrupted. You can say that, it is innate releasing mechanism or network where sign stimulus exists, once released from neural network; fixed action pattern leads to completion as well.

What factors determine if a species is fit to survive?
Tresset [83]

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
LiRa [457]

The right answer is inversion.

Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.

In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).

We distinguish :

Paracentric inversions:  The centromere in the chromosome is not included in the inversion.

Pericentric inversions:  The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
