D. Cholinergic antagonists
Bacteria, tree, algae, corn, and grass.
Answer:
c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
Explanation:
A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>
I annexed an image of the DNA structure.

Answer:
<h2>b) 640,000</h2>
Explanation:
Given:
Initial population = 10,000
Doubling time= 20 minutes
total culture allowed time = 2 hours
after 2 hours final bacterial population is 640,000
calculation:
10,000 doubles after 20 minutes = 20,000 and so on... final population after 2 hours = 640,000.
Answer:
Protein is made up of 20 different amino acids. Each amino acid consists of a central carbon. This central carbon is bonded to an amine group (NH2), a carboxyl group (COOH), a hydrogen atom and an R group.
Amino acids can be linked together when the amine group of one amino acid is bonded to the carboxyl group of a different amino acid. The COOH donates an OH group and the NH2 donates a H. The OH and H come together to form a water molecule, so this process is called dehydration synthesis - water is removed to form something new. The bond which holds the amino acids together is called a polypeptide.
