Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.

Birds have a hard time in cold weather, because their body temperatures are higher than those of humans They provide warmth and insulation against colder temperatures. Many birds grow extra feathers in the months leading up to colder weather, so that they'll stay warmer when temperatures drop.
1. The cell wall has lignin (hard substance): to prevent the xylem vessel from collapsing and withstand high pressure.
2. The absence of protoplasm (nucleus + cytoplasm) and cross wall: to allow water to move through the lumen easily.

Explanation:
The environmental sciences have documented large and worrisome changes in earth systems, from climate change and loss of biodiversity, to changes in hydrological and nutrient cycles and depletion of natural resources. These global environmental changes have potentially large negative consequences for future human well-being, and raise questions about whether global civilization is on a sustainable path or is “consuming too much” by depleting vital natural capital (13). The increased scale of economic activity and the consequent increasing impacts on a finite Earth arises from both major demographic changes—including population growth, shifts in age structure, urbanization, and spatial redistributions through migration and rising per capita income and shifts in consumption patterns, such as increases in meat consumption with rising income (19, 20).
