A nursery bed can be defined as a specially prepared temporary plot of land or garden which serves as a home for raising seedlings (young plants) prior to planting them in the main location (area). Thus, when older trees in the environment or surrounding dies or are cut-off, these younger plants (trees) propagated in the nursery bed are transferred to replace them.
<em>Some of the criteria or requirements for setting up a nursery bed are;</em>
1. Shed: this is one structure essential in propagating young trees.
2. Location/Site: a place near a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.
3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.
4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees. Pots are used for germinating young trees while boxes and plots are used for raising seedlings.
5. Soil type: different plants need different types of soil. These includes clay, loamy and sandy soil.
<h2>a) is the correct option </h2>
Explanation:
The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling
If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated
The second one would be my answer but also an answer that is not up there is that during an experiment when repeating the trials you might have to set up a new hypothesis every time and have to review the data several different times because of different results from each trial
hope this helps if not just let me know
