The correct answers are:
- New oceanic crust is created;
- Volcanoes erupt and produce more crust;
- Old crust is pushed away from ocean ridges;
When we have a divergent plate boundary, the plates move away from one another. As they move away, they leave a gap behind them, and lot of cracks in the thinner crust left behind. The high pressures from the mantle manage to push upwards the magma very easily through that crust and cracks. As the magma reaches the surface, it creates underwater volcanic activity. The magma comes out on the seafloor and quickly cools off. As it cools off, it creates new oceanic crust, thus the oceanic ridges. Because of the movement of the plates, and the constant new creation of new crust, the old crust is pushed away from the oceanic ridges.

The answer is B. Bell Jar
Answer:
The below options will complete the question
Select one:
a. Gap repair synthesis
b. Mismatch repair
c. Direct repair
d. Nucleotide excision repair
Our answer is surely A.
a. Gap repair synthesis
Explanation:
Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.
In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele
being digested away.
Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.
The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
The correct answer is letter A. The statement above is true that when animals eat the same type of food they are categorized in the same niche. Niches are ecological communities or ecosystems where specific organisms thrive and fit. Their evolutionary processes are also a result of these different niches found within the environment.
An enzyme may react with several substrate chemicals simultaneously.
True
