I believe the water treatment stated above is micron filtration. Micron filtration is a water treatment method where water is filtered through screens that have microscopic holes. The holes are measured in microns and the smaller the hole the more contaminants can be removed.

Answer:

Option D, micron filtration.

Explanation:

Micron filtration is a process of water clarification in which waste or impure water is passed through a set of sieve which can be of any pore size depending upon the impurity type i.e the size of contaminants or micro organism

However in reverse filtration water is force to passed through a semipermeable membrane on application of pumping force. Distillation is a physical process of cleaning in which mixture is separated based on difference in boiling points and chlorination is addition of chlorine or its compounds.

Thus, option D is correct.

Given what you know about the endosymbiotic theory, which region of the chloroplast below would you expect to be derived from th
san4es73 [151]

Answer:

Photosynthetic lamellae

Explanation:

The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.

The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  

The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.

Thus, Photosynthetic lamellae are the correct answer.

Remember the law of conservation of mass. The human body uses cellular respiration to make energy. Using the chemical equation f
posledela

With the equation of cellular respiration C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O, gaseous exchange takes place, glucose reacts with oxygen forming Adenosine Triphosphate used by cells.

About 21% of oxygen and 0.4% of carbon dioxide of air is inhaled while the air we breathe out contains 16.4% of oxygen and 4.4% of carbon dioxide because cells use oxygen inhaled to release energy and carbon dioxide as byproduct.

<h3>How does Cellular Respiration work?</h3>

Cellular respiration is how organisms convert fuel into energy and nutrients by combining oxygen with food molecules, sending the chemical energy for life sustaining activities while expelling carbon dioxide and water.

We inhale 21% of oxygen and 0.4% of carbon dioxide and exhale 16.4% of oxygen and 4.4% of carbon dioxide as by product during the process of cellular respiration.

How did Hershey and Chase ""label"" viral DNA and viral protein so that they could be distinguished? Explain why they chose each
vlabodo [156]

Answer:

As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.

So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.

Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.

What is the diploid of the zygote produced by fertilization—haploid or diploid?
nasty-shy [4]

Answer:

"Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

hope this helps!!:)

The illustration shows one of the ways resources are removed from the deep sea. There are many confusing regulations that limit
Sonbull [250]
The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone. 

However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.

Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.
