What is photonasty??

Answers

Answer 1
Answer: photonasty:
it is non directional movement of a plant towards or opposite a stimuli..
causes:
due to increase or decrease in turgidity or due to exceptional growth it happens...
Answer 2
Answer: photonasty is a type of nastic movement that is brought about by the stimuli which are non-directional but diffuse.Photonasty is induced by variation in the intensity of light.Many leaves that keep their surfaces fully exposed during the day time, drop at night.this dropping of leaves is brought about by changes in the turbidity of parenchymatous cells of the pulvini.

Acid rain is a secondary pollutant

Answers

The statement above is TRUE, acid rain is a secondary pollutant.

There are two basic types of pollutants, these are primary and secondary pollutants. The primary pollutants refer to those pollutants that are directly emitted from their sources. Examples are ammonia and carbon monoxide. Secondary pollutants on the other hand refer to those pollutants that are formed from the reaction of primary pollutants in the atmosphere. An example of secondary pollutant is acid rain, which forms as a result of reaction of sulphur dioxide and nitrogen in the atmosphere.

Final answer:

Acid rain is a secondary pollutant resulting from the reaction between sulfur dioxide and nitrogen oxides, primary pollutants, with water, oxygen, and other substances in the atmosphere. The resulting acid rain has a severe impact on both natural ecosystems and manmade structures. Despite regulations, it continues to be a significant issue in some industrial regions.

Explanation:

Yes, acid rain is indeed a secondary pollutant. It is caused when sulfur dioxide and nitrogen oxides, primary pollutants released from industrial processes and fossil fuel combustion, react with water, oxygen, and other substances in the atmosphere to form sulfuric and nitric acids. These acids then fall to the ground as acid rain. Acid rain is characterized by its acidity, having a pH of less than 5.

Acid rain has been a severe problem in industrial areas, particularly in North America and Europe until the 1980s. The acidity of this rain has led to the destruction of forests, damage to soil, and transformed freshwater lakes into an inhabitable environment for only the most acid-tolerant species. Acid rain also significantly corrodes marble and limestone structures. Regulatory interventions limiting the emission of sulfur and nitrogen oxide have reduced the severity of acid rain, but it remains a growing problem in areas like China and India.

The impact of acid rain on both natural and manmade environments is profound. It not only destroys the natural landscape and aquatic ecosystems but also causes the degradation of buildings and monuments, as seen in the case of the Lincoln Memorial in Washington, DC.

In which group would there be the greatest similarity between members in terms of structure and function?

Answers

There will be the greatest similarity between members of species in terms of structure and function.

How similarity increase and decrease?

The similarity between organisms increases from kingdom to species, whereas number of similar characteristics decreases from species to kingdom so we can conclude that there will be the greatest similarity between members of species in terms of structure and function.

Disease: Bipolar Disorder 1. In order to find the genes influencing this disease or condition, which database would you use first? We used: NCIB, OMIM, Wormbase, BLAST. 2. Approximately how many genes (or DNA elements) are involved in this disease or condition? Explain how you came up with this number 3. Provide the genetic symbol of one of the protein-coding gene involved in this disease or condition. Explain how you know this gene is a protein-coding gene. 4. What is the cytogenetic location of this gene in Question 3? Explain what this location means. 5.What is the function of the protein coded by this gene in question 3? 6. All human diseases and traits are polygenic. Explain what "polygenic" means in this context. 7. Explain how you could find out if C. elegans has a protein similar to the one in Quesion 5? If you know the location or the OMIM# of Bipolar Disorder I can figure out the all the questions. I can't find the Bipolar Disorder OMIM and also correct for wormbase.

protein-coding gene

The genetic code is stored in the DNA of a cell. it is copied during the process of replication. An enzyme called helicase unwinds the double strand helix of DNA by breaking the hydrogen bonds that hold the two strands together, thus separating forming  what is called replication fork. Next the enzyme DNA polymerase uses the single strands as a template and makes  a new DNA strand by copying the template.
