5 potential negative impacts on the environment
Explanation:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
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
You place a cell in a solution that contains 12 more water molecules than the inside of the cell. How will you know when the cell reaches equilibrium?
Answer:
B
Explanation:
the water molecules will stop moving across the
cell membrane because the cell membrane has
the same amount of water as in the solution.
This process is called osmosis

Where does haemoglobin become oxyhaemoglobin?
Answer:
Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.

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.

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 .

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 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.

Which courses should Don take in high school if he wants to pursue a degree and career in molecular biology? O anatomy and neurobiology O immunology and genetics O history and communications O physics and trigonometry
Answer:
anatomy and neurobiology
Explanation:
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.
Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.
A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.
