Consider the mRNA wheel.

A m R N A wheel is shown. An m R N A strand has components C A G A U G U A C G G A C G A U A A.
Which amino acid is coded for by the mRNA codon UAA?

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.

Ecological footprint is determined by measuring carbon dioxide emissions for a given region.

Ibelieve the answer is b) aerosol inhalation may lead to heart attacks.
