Answer:
Cell cycle checkpoints are surveillance mechanisms that monitor the order, integrity, and fidelity of the major events of the cell cycle. These include growth to the appropriate cell size, the replication and integrity of the chromosomes, and their accurate segregation at mitosis.
Explanation:
Chickens are capable of flight, however their domestication doesn't require it of them. After hundreds of years of being cultivated by humans, chickens have evolved to be less competent at flying than other birds. Chickens are ground feeders, which means they eat grubs and small plants. Since they do not need to hunt down prey like a hawk, they also do not need the wing strength to fly like one. Chickens are able to fly enough to access trees when they need to escape from predators.

Explanation:
Transmembrane protein are proteins that are firmly associated with membranes because it is integrated along the length of bilayer lipid membrane. This kind of protein is made up of two kinds of amino acid, hydrophilic or polar amino acid and hydrophobic or non polar amino acid. while peripheral protein loosely associated with membrane, they are present on the surface which means they are not integrated in to the cell membrane and facing intercellular fluid. this is why it contains only hydrophilic amino acid.
The primary amino acid sequence contains hydrophobic amino acid which identifies the protein as transmembrane protein. These amino acid are methionine (Met), leucine(Leu), valine(Val), glycine(Gly), tryptophan(Trp), isoleucine(Ile), phenylalanine(Phe), proline(Pro) and alanine(Ala)
