Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.
Explanation:
Answer:
Peroxidase activity increases and then decreases.
Explanation:
Peroxidase activity is greatly affected by the pH factor. Peroxidase works best at the pH of 7 while decrease or increase in pH will adversely affected its activity. So when change occurs from a moderately acidic environment having pH near 6 to a basic environment, the peroxidase activity increases when reach to neutral but decreases when go further to basic environment so we can say that peroxidase activity greatly affected on the pH of the solution.
The study of statistics. Like the increase or decrease of things. For example birth rates or the size of the human population.
I hope this helps :)
