Create some predictions to support the sunflowers in the future?
Oksi-84 [34.3K]

Answer:

The humble sunflower appears not quite of this earth. Its yellow crowned head sits atop its stalk like a green broomstick. Its seeds, arranged in a logarithmic spiral, are produced by tiny flowers called disc florets that emerge from the center of its head and radiate outward. But aside from being a biological marvel, the sunflower is also often in the scientific spotlight.

From understanding how new plant species emerge to studying “solar tracking,” which is how the flowers align themselves with the sun’s position in the sky, sunflowers are a darling in the field of science. However, researchers can only get so far in understanding a plant without detailed genetic knowledge. And after close to a decade, it has finally unfurled itself.An international consortium of 59 researchers who set their sights on the laborious task of sequencing and assembling the sunflower’s genome published their results in a 2017 study in Nature. This achievement will provide a genetic basis for understanding how the sunflower responds and adapts to different environments. “We are on the cusp of understanding sunflower adaptability,” says Loren Rieseberg, a leading sunflower expert at the University of British Columbia and a supervisor of this study.

With its genome assembled, scientists are hopeful for the next phase of the sunflower’s scientific career: as a “model crop” for studying climate adaptability in plants. This task is more complex and urgent now than ever. Climate change, according to a paper in the Annals of Botany, “will influence all aspects of plant biology over the coming decades,” posing a threat to crops and wild plants alike.

Explain the purposes of gene expression studies. Describe the use of DNA microarray assays and explain how they facilitate such
denis-greek [22]

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.

Energy sustainability can best be achieved by using ______. a. nonrenewable energy sources b. renewable energy sources c. carbon
Natali5045456 [20]

Answer:

Energy sustainability can best be achieved by using the renewable resources.

The renewable resources are the resources like water, wind and sun that can be renewed again and again after it is consumed once.

The term sustainability can be defined as the resources that can be used in the present generation and can be saved for the future generations as well.

So, sustainability can be best achieved when renewable resources are used.

Discuss ONE type of control that occurs at the chromosomal/DNA level and ONE that occurs at the mRNA level. Compare these two co
blagie [28]

Answer:

One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.

One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.
