Answer:
The answer is b) increased production of heat-shock proteins
Explanation:
High temperatures release a cascade of signals that drive the expression of some genes and the synthesis of so-called stress proteins, whose function is to stabilize the structure of proteins and enzymes and are involved in the protection of the photosynthetic system and stabilization of the membranes. Plants produce antioxidant and detoxifying enzymes to reduce the damage caused by reactive oxygen species, since the production of these substances is caused by heat stress.
Answer:
Charles Darwin
Explanation:
Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.
In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

Enzymes and acidic juices in the stomach, which break proteins down into smaller molecules, is known as proteolytic enzyme.
Proteolytic enzyme (also known as protease) is any group of enzymes that break down the long chainlike proteins molecules into smaller molecules (peptides) and later into amino acids. In the stomach, protein digestion takes place. The three main proteolytic enzymes; pepsin (produced by the stomach), and trypsin and chymotrypsin (produced by the pancreas) breaks down proteins into polypeptides which are eventually broken down into amino acids by several exopeptidases and dipeptidases.
