Answer: Option D

Most bryophytes lack true root and leaves.

Explanation:

Bryophytes are group of non vascular land plants that are found in moist environment. Examples are mosses, liverworts and hornworts. They reproduce by spores and not by flowers. They different from other plant in that they lack true roots, stems and leaves, presence of rhizoids function as roots to anchor the plant to the soil but the rhizoids does not absorb nutrient like other plant root.Bryophytes differ from other land plant in that they do not have xylem, a vascular system use to transport water internally rather they get water and nutrients through their leaves.

chubhunter [2.5K]

Answer:

\text{Present a flower with one characteristic changed to the normal pollinator. }\text{As a control, present a flower with no characteristics changed to the normal pollinator}

\text{Record any measure of pollination success}

\text{Repeeat for flowers with other characteristics changed}

<u />\text{Analyze the data to determine which altered characteristics affect pollination }<u />\text{success the most. This characteristic will be the result of the experiment.}<u />

Explanation:

The missing information is attached below.

 \text{Present a flower with one characteristic changed to the normal pollinator. }\text{As a control, present a flower with no characteristics changed to the normal pollinator}

For the control, you'll need something you're already familiar with. In this scenario, a normal flower with no changes in characteristics is the best control. And if no data is accessible, you still have data on the success rate of a typical flower, which can be used as a guideline. And, for the initial configuration, you can only adjust one characteristic so it would be easier to maintain track of and analyze the data gathered.

\text{Record any measure of pollination success}

Since the aim of your experiment is to examine the influence of flower characteristics on pollination performance, you should keep track of the active pollination events. To have more accurate results, this would require listing the total number of plants that were to be pollinated.

\text{Repeeat for flowers with other characteristics changed}

Once you've completed the initial examination, you'll need to run tests on various characteristics to see whether they have some impact on pollination performance. To see the importance of different characters on pollination, change only one trait in flowers; if you'd like to research combined results, create pairs and change them together.

\text{Analyze the data to determine which altered characteristics affect pollination }<u />\text{success the most. This characteristic will be the result of the experiment.}<u />

Your outcome is also the one that has gotten the most constructive or negative reviews. If some changed characteristic significantly affected the number of pollination efficiency, that is your outcome, because that is what you can mention as a good result and pollination enhancer.

Descirbe the structure of bone
vodomira [7]
The basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
