F1 stands for first generation in Mendels experiment
The term Southern Oscillation most nearly refers to a reversal of wind direction
Answer: Option D
<u>Explanation:
</u>
Southern Oscillation, a component of the atmosphere in one large-scale interaction called El Niño / ENSO. The equatorial cycle fluctuates after irregular periods of about many years in response to alter in atmospheric pressure in the tropical Indo-Pacific.
With the weakening of the east-west wind during the southern oscillation phase, warm water may slide back west, increasing the flow of the equator up. Surface water temperatures and sea levels fall west and rise east, which is why this event is called El Niño.
Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.
Answer:
They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.
