Me with questionsanswer both questions at the same not only one.. 19 points how would the pattern of apoptosis differ in a duck's webbed foot compared to the pattern of apoptosis in a mouse's foot? what are cyclins? what do cyclins do?

1. a mouse's toes undergo apoptosis during a late stage of development. due to signaling protein: BMP4 that instructs cells in webbing to undergo apoptosis

- both embryos express BMP4 gene but differ in expression of gene Gremlin- ducks

-- Gremlin protein inhibits BMP4 from signaling for apoptosis= webbed foot

2. Cyclin is a family of proteins that control the progression of cells through the cell cycle by activating cyclin-dependent kinase

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
