Answer: B. taking the first complete cores of deep-sea sediments.
Explanation:
The Glomar Challenger was regarded as the first research vessel that was designed for drilling into the ocean and then take core samples from it.
Therefore, based on the options given, the Glomar Challenger (Joides Resolution) is known mainly for taking the first complete cores of deep-sea sediments.
Therefore, the correct option is B.
Answer:
Explanation:
Wild guess. Photosynthesis
A chromosome number of 92
Genes B and C with 10% recombination frequency are closest to each other. Because recombination happens at random, the distance between genes that are farther from each other creates higher recombination frequency. A low recombination frequency of 10% means the genes are closest to each other. The short distance between the two genes allow fewer recombination to happen, thus the frequency is low.
