Answer:
Remaining silent.
Explanation:
Remaining silent, seeking refuge, and reducing overall activity levels are the ways that is used by the prey to avoid or to save itself from the predators. The prey remain silent when its senses the presence of predators because to stop giving cues to the predators to its presence. Some prey hide itself in the place for sometime in order to save itself from the attack of the predator while some preys decreases daily activities in order to decrease the cues given to the predator for its presence.
Explanation:
In the given question, the DNA segment of human can be sequenced or analysed through three processes:
2. DNA sequencing: DNA sequencing is the method by which the sequence of the nucleotides which are adenine, thymine, guanine and cytosine are sequenced in the correct order.
1. DNA probes: probes are synthesised nucleotide sequence which binds to specific sites of DNA. Since these probes are complementary to the specific region therefore the DNA polymorphic sequence can be sequenced.
3. Polymerase chain reaction: PCR is the technique which can amplify or replicate the DNA sequence but this involves the isolation of specific DNA sequence.
Crossing over leads to genetic variation.
Crossing over is the process during meiosis during which homologous pairs of chromosomes exchange genes, giving rise to new combinations of genes within the chromosomes. This is an important source of genetic variation.
