What type of research method would best answer the question “How many rivers in Florida have nitrate pollution in them?”
Answers
Answer:
Field study
Explanation:
I took the quiz and got it right. Hope this helps :)
The type of research method that would best answer the given question is field study. The correct option is C.
What is field study?Field studies are research activities that take place outside of your office or lab, in the context of the user.
There are numerous field-study methods and activities to choose from. Field studies also differ significantly in terms of how the researcher interacts (or does not interact) with participants.
Field research is a qualitative research method that involves observing and interacting with people in their natural settings in order to understand and interpret the social interactions of groups of people, communities, and society.
Field studies provide students with first-hand experiences that promote critical thinking, long-term retention, transferability, positive attitudes toward science, appreciation for nature, and increased scientific curiosity.
Field study is the type of research method that would best answer the given question "How many rivers in Florida have nitrate pollution in them?”
Thus, the correct option is C.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answers
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

Researchers want to use eDNA to look for an invasive species in a waterway.
Which step should they do last?
A. Cut the DNA into fragments of different sizes.
B. Compare the samples with a positive control.
C. Isolate DNA from the waterwakin question.
D. Stain the gel to reveal a banding pattern.
Answers
The last step to observe different DNA patterns is to stain the gel to reveal a banding pattern (Option D).
DNA extraction, polymerase chain reaction (PCR) and fragment separation by gel electrophoresis are basic molecular techniques used to identify patterns in DNA.The patterns in DNA can be used for identifying an individual in a population, distinguishing different species, etc. These patterns can be obtained by using restriction enzymes.There are different dyes used to stain DNA before the identification of patterns in DNA.For example, ethidium bromide is a widely used dye to stain DNA before fragment separation by agarose gel electrophoresis.In conclusion, the last step is TO STAIN the gel with a DNA dye to reveal a banding pattern (Option D is correct).

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answers
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.
