Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
Answer:
- The independent variable is the concentration of sucralose present in the plant.
- The dependent variable is the growth rate of the plant.
Explanation:
The study designed through the steps of the scientific method would be done as follows:
Observation: Sucrose is a very important molecule for the development and growth of plants, based on which sucralose, which is formed from sucrose, can be important for the same factors.
Question: Can sucralose influence plant growth as well as sucrose?
Hypothesis: Sucralose may establish some influence on plant growth.
Experimentation: Select a number of seeds inoculated with sucralose molecules and select the same number of seeds that were not inoculated with anything. Provide the same type of soil and environmental factors so that seeds can grow in the same way. Weekly evaluate the growth of the plants generated by each seed for a certain period of time. After this period of time, measure the weight of the plants and their roots. Place the plant and root to dry in an oven and measure the weight of the plant and root once again.
Analysis of results: compare the average weekly growth of plants generated by inoculated seeds, with plants generated from uninoculated seeds. Compare the average weight of plants generated by seed inoculated before and after kiln-dried. Compare the weight average between plant roots generated by inoculated seeds before and after kiln-dried. Assess whether there was a significant difference between the means.
Conclusion: Using the data presented in the evaluation of the experiment, state whether the hypothesis developed provides true or false information.
<u><em>Note: it is important that the seeds are from the same species of plant.</em></u>
Answer:
Well the model above is showing all the planets in order from how close or far away they are from the sun and it also seems to show the scale of each planet compared to another.
Explanation:
As for the Evidence or why it is important to know this is because the scale and location of the planet to the sun directly effects everything about the planet, its Atmosphere, tempterue and rotaion. And the more we learn about all plants we can better underatand our own geological past behavior of its Atmostohere and futute clamatic trends.
Answer: E. reforestation
Explanation:
Reforestation is a process of planting trees in an area so as to conserve the land as future forest. According to the given situation, reforestation is the practice which can be used by the biologists to grow nitrogen fixing plants in an area so as to increase the nutrient concentration of the soil which have been depleted.
