Answer:
B) has no new stars being formed.
Explanation:
An elliptical galaxy is primarily defined as the kind of galaxy that is a gathering of billions of stars bound gravitationally. The stars in such a galaxy orbit in an egg-shaped projection around the focus/center of mass.
As per the question, an elliptical galaxy 'has no new stars being formed.' It rather contains older stars having low mass and gas. <u>The first and second options are incorrect as an elliptical galaxy follows an egg-shaped pattern that denies both the claims 'spiral-shaped and has no recognizable shape.' The last option is wrong as the stars in such a galaxy are old and therefore, contain less gas</u>. Thus, <u>option B</u> is the correct answer.
Answer:
A. volcanic activity
Explanation:
In a subduction zone, a noticeable increase in volcanic activity can be observed.
A subduction zone is a plate margin in which a denser lithospheric plate goes beneath a lighter one. One such example is illustrated between an oceanic plate which subducts beneath a continetal plate.
When a plate subducts, it goes deeper into the earth and reflux melting of the plate occurs. The melting point of nearby rocks is considerably lowered by dewatering of the subducting plate. The water causes reflux melting and magma forms. Appropriate conduits like fractures can carry the magma to the surface to initiate volcanic activities. This is the origin of volcanic activities within the continent or continental volcanism.
Answer: Adaptive Speciation
Explanation:
The two species evolved as s result of adaptive Speciation.
Adaptive speciation occurs when biological interactions induce disruptive selection and the evolution of assortative mating, thus triggering the splitting
understanding processes of adaptive speciation, in which the splitting of lineages is an adaptation caused by frequency-dependent selection. Adaptive, or sympatric, speciation has been modeled since the 1960s.
Number two, because the definition of geography is :the study of physical features of the earth and its atmosphere ,and of human activity as its affected by these, including the distribution of populations and resources and companies.
