Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood
katen-ka-za [31]

Answer:

Cardiac output = 20 L/min

Explanation:

The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than  when resting.

Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min

Cardiac output  = stroke volume * heart rate

For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat

heart rate = 200 beats/min

Cardiac output =0.1 L/beat * 200 beats/min

Cardiac output = 20 L/min

valina [46]
<h2>Xylem;phloem and cork</h2>

Explanation:

Wood is mainly known as secondary xylem found in trees

  • Xylem is basically the vascular tissue which is responsible for the conduction of water and nutrients from the roots to shoots and leaves
  • Secondary xylem is formed from secondary growth and is associated with lateral growth and grows from the vascular cambium
  • Its cell walls are thickened by deposition of lignin which provides mechanical support to plants and consists of tracheids and vessels that are shorter and wider
  • In large woody plants secondary xylem get differentiated into heartwood and sapwood

Bark is essentially made of phloem and cork

  • Bark sole purpose is to provide protection to trees
  • The inner bark is produced by vascular cambium which consists of secondary phloem whose innermost layer transports food from the leaves to rest of the plant
  • The outer bark is a dead tissue which is the product of cork cambium
