D. They make their own food using energy from the sun. Trees use a process called photosynthesis to convert light energy from the sun, carbon dioxide, and water into glucose (the food) and oxygen.
I'd say your answer is,
C. the attraction and bonding of ions with equal opposite charges.
Because you will focus past ("overshoot") your specimen. (Like using a race car as a shopping cart: it's too fast, and you'll fly past the cereal and never even see it before you realize you need to stop.)

D... i took science last year
Answer:
5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
