3. What are two major phases of cell division?
Igoryamba
3# Interphase is divided into three phases: G1, S, and G2. The subsequent mitotic (M) phase consists of two processes: mitosis, the process of nuclear division, and cytokinesis, division of the cell's cytoplasm. Each mitotic phase results in the formation of two cells that are genetically identical to the parent.

Sorry I can't remember the rest of the questions.

Calculate the cardiac output if heart rate (HR) is 90 beats per minute, stroke volume (SV) is 110 ml/beat, end diastolic volume
Yakvenalex [24]

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.

A student is standing 8 m from a roaring truck engine that is measured at 20 db. The student moves 4 m closer to the engine. Wha
icang [17]

Answer:

80 dB

Explanation:

Sound intensity is inversely proportional to the square of the distance traveled by the sound.

Thus;

r1^2 divide by r2^2 = L2divideL1

where r= distance (m)

L= sound intensity (decibal dB)

8squared divide by 4 squared = L2 divide 20 dB

L2 = 4 × 20

L2= 80 dB

This means that the sound is increased from 20 dB to 80 dB.
