B) the ability to work top down bottom up
B it the answer Fasho
Answer:
The lectin pathway or lectin complement pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade.
Metals are strong, high density, good conductors of heat and electricity, and are also malleable and ductile. While non metals are brittle, dull looking, are poor conductors of heat and electricity, and are overall weaker.
Current evidence suggests that eukaryotes represent one or more endosymbiotic events in which the host cell was: <u>mitochondrial genomes</u>
What is mitochondrial genomes?
The DNA found in mitochondria, which are cellular organelles found in eukaryotic cells that transform chemical energy from food into a form that cells can utilise, such as adenosine triphosphate, is known as mitochondrial DNA (mtDNA or mDNA)](ATP). Only a small amount of the DNA in a eukaryotic cell is contained in the mitochondria; the majority of the DNA is found in the cell nucleus and, in plants and algae, also in plastids like chloroplasts.
The first large portion of the human genome to be sequenced was mitochondrial DNA.
According to this sequencing, the human mtDNA contains 16,569 base pairs and codes for 13 proteins.
Animal mtDNA serves as a cornerstone of phylogenetics and evolutionary biology because it evolves more quickly than nuclear genetic markers .
