The Earth core has two layers: the outer core, and the inner core. Moreover, the magnetic field protects Earth from solar weather.
The Earth's magnetic field is an invisible layer that protects life from the majority of the solar wind blast.
The magnetic field covers us from charged solar particles that crash into it and then flow around it.
Moreover, the Earth core has two layers: the outer core and the inner core, which are separated by a boundary known as the Bullen discontinuity.

The correct answer is option D, Temporal isolation
Temporal isolation is the mechanism which prevents the mating of closely related species living in the same ecosystem. Basically the reproductive barriers prevent these species from interbreeding. Temporal isolation is a prezygotic barrier that causes “time isolation” between the breeding period of two closely related species. The difference in time could be “difference in time of day”, “ difference in season of mating”, “difference in months” and in some cases “ difference in years”.

ANSWER: None of the above options are correct.
Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)
Therefore where HR= 90bpm and SV= 110ml/min,
CO = 90 × 110 = 9900ml/min or 9.9L/min.
EXPLANATION:
CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.
Cardiac output is the product of two variables, stroke volume and heart rate.
STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.
HEART RATE is the count of the number of times the heart beats per minute.
