Answer: Yes, estimation of a population of plant species in a given area. The tool I used was a QUADRAT.
Explanation:
Plants in a small area are easy to count and their distribution is recorded on a map or scale diagram for the area. For larger areas, quadrats are used to obtain a fairly accurate estimate of the number and types of plants in those large areas.
The ESTIMATION of the population of plants can be done using a method called the quadrat sampling method. Here, a QUADRAT which is a rectangular or square frame(tool) made from thick wire, is thrown at random several times. On each landing, the area covered by if is observed. The type of species and their number within the quadrat are recorded. The average number of times each species appears is calculated and the most frequent or dominant species is then determined.
Some quadrats are specially made to mark off an area for the study of seasonal variations of plants. They are sturdier, larger and permanent and can thus serve their purpose through the seasons. These quadrats often have a mapping grid attached so that the flora within it can be mapped at regular intervals.

How did the CT enterography and the technetium scan lead to the correct diagnosis?
Answer: hope it helps..
Explanation: CT enterography is a new non-invasive imaging technique that offers superior small bowel visualisation compared with standard abdomino-pelvic CT, and provides complementary diagnostic information to capsule endoscopy and MRI enterography. CT enterography is well tolerated by patients and enables accurate, efficient assessment of pathology arising from the small bowel wall or surrounding organs. This article reviews the clinical role of CT enterography, and offers practical tips for optimising technique and accurate interpretation.
The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5
Answer:
A
Explanation:
Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.
The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.
What is a Template strand?A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.
The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.
In mRNA, the Thymine (T) is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.
Therefore, it is well described above.

During phagocytosis of one cell to another, the larger cell engulfs the smaller cell by enclosing it in a part of its plasma membrane which then pinches off so the cell is then within the larger cell. Given this may have been the process that brought bacterial cells into the ancestors of eukaryotic cells as endosymbionts, what structural characteristics might be expected in mitochondria and chloroplasts?
Explanation:
Phagocytosis is the process by which cells ingest large particles, including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vesicle. During pinocytosis, cells take in molecules such as water from the extracellular fluid.

How does RNA polymerase know where to start and stop making a strand of RNA?
Answer:
Each gene has a beginning and an end. At the beginning of each gene is a similar sequence that tells the RNA polymerase to start working. The same is true at the end of each gene where a specific sequence tells the RNA polymerase to stop transcription
Calculate percentage change in mass for chip 5
Answer:
The correct answer is - 14.41%.
Explanation:
Given:
The initial mass of chip 5 -
end mass of chip 5 -
Percent Change in Mass = /
Formula used:
Mass Difference= Final Mass- Initial Mass
Percent Change in Mass = (Mass Difference/Initial Mass) *100
Solution:
Putting the value in the formula:
Mass Difference = 2.15 - 1.84
= 0.31
Percent Change in Mass = (0.31/2.15)*100
= 14.41
Thus, the correct answer is - 14.41.
Answer: -14.41 %
Explanation:
start of chip 5 the mass was 2.15 and towards the end mass of the beetroot chip it changed and the mass was 1.84 grams. the mass difference is 0.31 and i got this by doing 2.15 - 1.84 .
