Magma seeps up along plate boundaries and forms mountains.
Factor 1 creates competition and factor 2 creates genetic variation.
Explanation:
Question 1: Magma seeps up along plate boundaries and forms mountains.
When lithospheric plates move apart they create divergent plate margin where magma seeps up along the plate boundary and forms series of mountains. The mid oceanic ridge was formed this way.
- The lithosphere lies on the weak and molten asthenosphere.
- Different plate interactions produces a wide range of plate movement.
- Along a divergent margin usually, two oceanic plates are forced to move apart.
- The forces the asthenosphere to rise through seeps as magmatic bodies.
- The rising magma them crystallizes along the margins of the plate to form mountain chains like the mid-oceanic ridge.
- It is common to find young rocks at the plate margin and the older ones away from spreading centers.

Question 2: Factor 1 creates competition and factor 2 creates genetic variation.
Scarcity of space leads to competition between organisms and availability of mates creates genetic variations.
- In an ecosystem with limited space, there will pressure on available resources.
- This will lead to different organism developing strategies to efficiently adapt to their environment.
- Organisms will in turn begin to compete with one another for the limited resources.
When we have a diverse number of mating options, genetic variation occurs. This suggests that we can have different gene combination as a result of the mating organisms.
A variation in the genetic pool of a place leads to better adaptable traits to survive the environment.

Meiosis II will have
chromosomes.
Meiosis:
- Somatic cells divide during meiosis, a process in which the genetic makeup or quantity of chromosomes in the daughter cells is maintained.
- In sexually reproducing organisms, a kind of cell division known as meiosis results in a decrease in the number of chromosomes in gametes (the sex cells, or egg and sperm). Human body cells, also known as somatic cells, have two sets of chromosomes and are diploid (one from each parent).
- A single cell splits twice during the meiosis process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.

The five major types of estuaries classified by their geology are coastal plain, bar-built, deltas, tectonic and fjords. In geologic time, which is often measured on scales of hundreds of thousands to millions of years, estuaries are often fleeting features of the landscape.
