Answer:

Repetition refers to performing multiple trials throughout an experiment. Repetition reduces mistakes and increases one’s confidence in the results. Replication refers to the ability of a process to be repeated by another individual. When a scientist replicates the experiment of another, the experiment should produce the same results.

Answer:

Explanation:

Repetition is a process by which multipliy sets of measurements or experiments are made in one scientific investigation and are multiple trials while replication on the other hand occurs when a scientific investigation is carried out by a different investigator and when the entire experiment is redone.

A marine biologist is studying dolphin calls and notices that sometimes the calls sound louder based on the background noise in

julsineya [31]

Answer:

The correct answer is option 1. "Amplitude".

Explanation:

Waves of sound have different properties, among them amplitude is the one that determines the loudness or volume of the sound. The amplitude is the height of the wave, measured in meters, or in other word the maximum displacement of the sound's particle from its position of equilibrium. If a dolphin calling sounds louder because of the background noise, the waves of the sound that the dolphin produces would have a higher amplitude.

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I

Bogdan [553]

Answer:

Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like 'photocopies' of original parent chromosomes; joined together at the Centromere.

They are exactly similar in all ramification; with the same gene and allele compositions..

However; slight differences arise between the two identical sisters due to mutation from errors at replication;and also in the length of telomere repeats.

Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

However, they are genetically similar in composition; if they are contained in homologous chromosomes. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .
