Answer:
Carbon dioxide
Explanation:
Xylem and phloem are the two conducting tissues of a vascular plants. They are referred to as vascular bundles. Xylem and phloem are responsible for conducting certain substances from one part of the plant to another.
The xylem is responsible for conducting WATER AND DISSOLVED MINERALS from the root of the plants to other parts e.g leaves, stem, flowers etc. while the phloem conducts sugar (product of photosynthesis) e.g glucose from the leaves of the plant to other parts including the stem, root etc.
According to this question, xylem or phloem does not conduct or carry gaseous substances like carbon dioxide (CO2).
Protein microarrays, an emerging class of proteomic technologies, are fast becoming critical tools in biochemistry and molecular biology. Two classes of protein microarray are currently available: analytical and functional protein microarrays. Analytical protein microarrays, most antibody microarrays, have become one of the most powerful multiplexed detection technologies. Functional protein microarrays are being increasingly applied to many areas of biological discovery, including studies of protein interaction, biochemical activity, and immune responses. Great progress has been achieved in both classes of protein microarrays in terms of sensitivity, specificity, and expanded application.
Answer:
Cats also purr when they are nervous or in pain, leading some experts to believe that this uniquely feline vocalization is actually a method of self-healing. A domestic cat's purr has a frequency of between 25 and 150 Hertz, which happens to be the frequency at which muscles and bones best grow and repair themselves.
