- (A) Allergies
- (B) bacteria
- (C) Pollution
- (D) injury
- (E) fungi
- (F) sweating
- (G) the skin
- (H) smoking
--
Let's think first: Pneumonia may be caused by an infection or injury of the lungs. Streptococcal pneumonia is caused by the bacteria Streptococcus pneumoniae. Streptococcus can infect the lungs following injury.... So the answer is [(D)]

- (A) A kernel
- (B) protein
- (C) food
- (D) Energy.
- (E) power
- (F) Joules
- (G) alleles
- (H) Energy
--
Let's think first: Molecules of tRNA bring amino acids to the ribosome in the correct sequence. Ribosome binding site, start and stop codons, protein coding sequence. Molecules of tRNA bring amino acids to the ribosome to create proteins.... So the answer is [(B)]

Why does vesicle transport need energy?
Options:
- (A) it helps plants in growing
- (B) to prevent movement
- (C) for movement of substances
- (D) during the day
- (E) Transfers energy
- (F) flow of electrons
- (G) to breath
- (H) magnetism
--
Let's think first: Vesicle transport requires energy, so it is also a form of active transport. Active transport involves movement of substances against a chemical gradient. Vesicle transport requires energy for movement of substances against a chemical gradient.... So the answer is [(C)]
