Answer:
The correct answer is A DNA is replicated before mitosis begins
Explanation:
DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.
DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.
DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.
Answer:
The answer is option D "Succession rates would depend on the number of early arriving facilitator species"
Explanation:
Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.
In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.
Succession is a progression of reformist changes in the structure of an ecological community over the long run.
In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.
In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.
Answer:
Thyroid hormones are sometimes present in either abnormally high or low levels in people with bipolar disorder.
Explanation:
→depression is associated with low levels of thyroid hormone
→mood elevation is associated with high levels of thyroid hormone.
furthermore; reducing the levels of high thyroid hormone in the blood stream with lithium may mitigate manic symptoms in patients of bipolar disorder,
this buttress the point that fluctuations in thyroid hormones is a causative factor
