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:
True. Law of Segregation is one of the principles of herdity formulated by Gregor Mendel. It states that genes from a pair of homologous chromosomes separate during meiosis and then distributed to different gametes.
Knowing that the second polynucleotide strand of DNA complements and or base pairs with that of the original strand, based on the base pairing rules as shown:
A - T
G - C
Then the complementary strand would be :
TAGCCAT
Answer:
How do amino acid sequences provide information about evolutionary relationships among organisms? They allow scientists to compare the order of the acids in a protein to see how closely related the organisms are.
Explanation:
Carbon cycles through ecosystems. ... To release the energy in food, organisms break down the carbon compounds—a process called respiration. Carbon is released and cycled back into the atmosphere as carbon dioxide. When living things die and decay, the rest of the carbon that makes up living matter is released.
