Answer:
The correct answer is B. <em>Philippine plate converging with the Pacific plate, forming Mariana Islands in the Pacific Ocean</em>
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.
The Mariana Islands in the Pacific Ocean are examples of these volcanic islands.
Let’s assume a wire-hair terrier is a true breed for wire hair with alleles (BB) and a smooth-hair terrier is true breed for smooth hair (bb). Allele B is dominant over its allele b. When these two terrier mated and produce offspring wire-hair terrier and smooth-hair terrier in the ratio 3:1.
Based on this result it can be inferred that –
a. The pattern of inheritance is monohybrid cross.
b.Genotype of wire-hair terrier (1BB and 2 Bb) and genotype of smooth-hair terrier is (bb)
c. Phenotype ratio will be 3:1 and genotypic ratio will be 1:2:1.
The cells that are produced by mitosis are sex cells
The correct option is D.
The gasoline fuel used inside the car has inherent potential energy in its molecules. When the car is started, this potential energy will be converted to heat energy. The heat energy will then be used to carry out mechanical works in the engine of the car, this makes the car to move forward. At the point of moving, the energy in the car has been transformed to kinetic energy, which is energy in motion.
