The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.
This type of movement is called thigmonasty which is a non directional plant response to being touched.
I disagree it should be A
The most likely cause of the beak variation is the food source of the finch, the break size and shape was adapted to most likely have easier and better access to food. <span />
The measles virus and rubella virus are two separate viruses. They have different DNA and RNA structures, and the vaccination for the measles virus only "knows" how to attach itself to measles and destroy the virus. It doesn't know how to attach itself to the rubella virus to destroy it, as the vaccination is needed to inform it how to.
The advantage of vaccinating a large amount of the population is that it reduces the chance someone will catch sickness by a great amount, and can possibly eradicate the virus.
