Answer:
The given figure depicts the process of translation.
Translation is the process by which the mRNA is deciphered into the amino acid sequence of the polypeptide chain.
Ribosomes serve as the site of the translation.
The small and large subunits of the ribosome form the complex around the start codon of the mRNA.
It created three sites namely; A, P and E sites.
A site is a site where the charged tRNA enters the complex.
It then adds the amino acid specific to the codon sequence of the mRNA to the growing polypeptide chain at P site.
Uncharged tRNA then leave the complex through E site.

Answer: C. Microfilaments
Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.
Answer:
Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.
Explanation:
Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.
The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.
