Answer:
When a single amino acid is encoded by more than one codon.
Explanation:
Degeneracy is when a single amino acid is encoded by more than one codon. This pehonomenon was first described by Lagerkvist where there are more codons than amino acids that could be encoded.
Answer: Plants
Explanation: Less solar radiation would mean less sunlight for photosynthesis which means that they won't get enough energy for survival and might die out.

Answer: True
Explanation:
<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.
To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).
