Answer: Primary and secondary succession
Explanation: In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.

Answer:
collecting duct
Explanation:
The collecting duct is part of nephrons and has mainly two types of cells. These are called principal cells and intercalated cells. The principal cells of collecting duct have receptors for ADH and aldosterone. The function of the anti-diuretic hormone (ADH) is to reduce the fluid loss from the body when blood volume and blood pressure fall and the person experiences dehydration. In response to ADH, transcytosis of water in collecting duct is stimulated. This results in the absorption of most of the water from the filtrate and formation of concentrated urine.
