Answer:

The control of this experiment is the rat that received sugar in place of the drug.

Explanation:

In a scientific experiment, control is characterized by the individual (or object) who has not received what is being tested in the experiment. In the case of the above question, the experiment wants to test the effectiveness of a drug in fighting cancer. All rats received different doses of this medicine, except for one mouse that received sugar in place of the medicine. This mouse is the control of the experiment and will serve to compare how cancer is reduced in individuals who received the drug compared to those with cancer who did not receive the drug.

BaLLatris [955]
<h2>Vascular and Nonvascular Plants </h2>

Explanation:

Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants .

  • <u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
  • The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem
  1. The xylem transports nutrients to various parts of the body from the leaves.
  2. Phloem conducts water and other nutrients from the roots to various parts of the plant .
  • These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
  • Dicots are with tubular vasculature.  
  • Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
  • <u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
  • These plants are lack proper shoot or root system.
  • It includes mosses, hornworts etc.
