<h3><u>Answer;</u></h3>
D) <em>The more dense oceanic plate subducts under the less dense continental plate. Subducted plate melts due to heat and friction. Melted plate, now magma, rises up to the surface.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Volcanoes may be formed at convergent plate boundaries or at divergent plate boundaries. </u></em>
- <em><u>When two tectonic plates collide, they form a convergent plate boundary. Normally, one of the converging plates that is the dense oceanic plate will move beneath the other, which is the less dense continental plate a process as subduction. </u></em>
- <em><u>The friction between the plates in the subduction zone as a result of constant movement, melts the Earth's crust causing the underneath rocks to turn into magma.</u></em>
- <em><u>The magma creates great pressure and rises towards the surface of the earth, and on reaching the surface it is called lava, and a volcano is formed.</u></em>
They form an ionic compound.
Answer:
X: Producers undergo photosynthesis;
Y: Decomposers return carbon to the soil and release waste
Explanation:
Producers, for example, a clover, will take the CO2 in the atmosphere and use it in photosynthesis to turn it into nutrients, then the consumers, for example, a deer, will eat the producer to gain nutrients. After the consumer dies, the decomposer, for example, fungus, will eat away at the consumer, releasing CO2 into the atmosphere. Then the cycle keeps going.
Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population.
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yiels new species or offsprings that are genetically different from their parents, and causing uneven gene flow or disruption of alleles known to have been prevalent among the parent organisms
So, only option B is true
Answer:
I think that it would be all of them
