My answer: A
Step by step explanation:
Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
Answer:
tRNA.
Explanation:
RNA molecule is made from the template DNA by the process of transcription. Three main different types of RNA molecule are rRNA, mRNA and tRNA.
tRNA or transfer RNA is an one of the most important RNA molecule. tRNA molecule contains the anticodon that are complementary to the codon of the RNA molecule. tRNA specifies for a particular amino acid.
Thus, the correct answer is option (C).
Answer:
More branching or folds.
Explanation:
Adaptation may be defined as the ability of the organism to adapt and survive according to its environment. Physical, physiological and chemical changes occur in the body of organism for the adaptation process.
The evolution of the increase in the size of the animals might also changes their internal physiology. The lungs and digestive tract also evolved as the size of the organism get bigger. The lungs has the alveoli to increase the surface area and inhalation of more oxygen in the body. Digestive system has villi or folds that increases the surface area for digestion and absorption.
Thus, the answer is more branching or folds.
