A Germ cell aka sex cell mutation can cause down syndrome when theres an extra chromosome d is a mutation caused by inserting or deletion of a nucliotide
1. is c
2. is d
Answer:
a system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression.
Answer:
Predator
Explanation:
Since a Praying Mantis is an animal that naturally preys on others, it would be considered a Predator
Answer: Humans killing a majority of the natural predators will cause a drastic increase of the prey populations and make food,shelter and other resources scarce.
Answer:
DNA coding for rRNA changes relatively slowly
Explanation:
The ribosomal ribonuclei acid( rRNA ) is used for Ribosome synthesis. Ribosomes is the organelle for translation of encoded amino acids in protein synthesis in the cells. The gene that codes for rRNA is called rDNA.Thus must of the functionalities of rDNA are encoded rRNA. Therefore researchers use rRNA for comparison investigations because;
<u>1.The coding region on the rDNA is highly conserved, with low rate of polymorphism, thus rDNA for rRNA transcriptions pathways is relatively slow compare to the one of high rate of polymorphism.</u>
<u />
2. Consequently the conserved region( well preserved amino acid sequence) of the rDNA encoded in rRNA, with low polymorphism, and therefore slow transcription pathways enabled the use of rRNA for investigations of relationship between taxa. Since rRNA is present across all organisms,prokaryotes and eukaryotes the highly conserved coded region of low mutation and therefore slow changes, enable accurate comparison.
