What most likely happens when lithospheric plates move apart deep below the ocean?
Alisiya [41]

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.

Look at the diagram of a euglena cell. Early scientists were not sure how to classify this organism.
Setler79 [48]

Answer:

Since Euglena have features of both animals and plants, early taxonomists, working within the old two-kingdom system of biological classification, found them difficult to classify - not because they had features different from an animal and different from a plant, but because they had some features that were animal-like and some features that were plant-like.

What is the sequence of events in Mendel's experiment with the pea plant?
boyakko [2]
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
