Answer: Option (C)
Explanation: Wegener's theory of Continental drift was replaced by a modern theory called the 'plate tectonic theory'. This theory was able to prove what wegener could not and so was universally accepted.
The new evidences supporting this theory were-
- The coastlines of east America and west Africa are similar in shape suggesting that they might have existed together once upon a time
- Similar fossils were found at different continents such as the glossopteris fauna
- Similar rock sequences found at different places determined by the correlation method
Hence the correct option that satisfies the above question is option (C)

Explanation:
Answer:
B) sugars; leaf; apical meristem
Explanation:
Phloem is one of the vascular tissues and is mainly involved in the transport of sugars. Phloem sap is the aqueous solution that moves through sieve tubes of phloem. Phloem sap mainly consists of sugars but also carries amino acids, hormones, and minerals. Sucrose is the most prevalent sugar.
Phloem sap moves from sites of sugar production (called sugar sources) to sites of sugar use or storage (called sugar sinks). A sugar sink is an organ that either uses the sugars for energy production and other functions or stores it.
In late spring, the fully grown leaves serve as a source of sugars. Apical meristem is responsible for the growth of stem and root length and serves as a sugar source as it obtains sugars from the leaves and uses them during the growth of shoot and roots.
Answer:
A sequence of three nucleotides forms a codon, which then codes for a specific amino acid. If a nucleotide were to be deleted, all codons after would be affected and could possibly code for new, incorrect proteins.
