The option that correctly describes the relative dissolved oxygen concentration in the flask with algae will compare to the control flask is C. The dissolved oxygen in the flask with algae will be higher in the light but lower in the dark.
What factors can increase the amount of dissolved oxygen in water? Temperature, pressure, salinity and biological organisms are the major contributing factors that affect dissolved oxygen. If the medium contains a photosynthetic plant that too in the presence of light, then this will increase the dissolved oxygen. On the other hand, increased salinity and warm water decrease the amount of oxygen dissolved in water. As given above, the flasks containing the green algae and water are given 12 hours of light and then put 12 hours in darkness. The flask that contains the algae contains more dissolved oxygen during the light hours as algae are photosynthesis in nature and thus, they will do photosynthesis during 12 hours of lighting. But, the control flask contains only water and thus, there will be no addition of dissolved oxygen.Thus, we can conclude that flask that contains algae have more amount of oxygen dissolved than the control flask containing only water. During 12 hours of darkness, no photosynthesis occurs and hence algae containing flask will have a lower amount of dissolved oxygen.

What is the function of histones- proteins that aide in dna replication
Answer:
Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.

Answer:
C. average distance between variable scores and the mean in a set of data
Explanation:
The standard deviation is used to find how far data points are from the mean. This can be used to create a bell curve, which represents what percentile data points are relative to the set. A bell curve shows how the data points are distributed. Standard deviation can be found from an entire data set or just a sample.

Write down the classes of foods digested in the gut from the mouth to the duodenum?
Explanation:
The chyme is gradually pushed down the duodenum by peristaltic waves which flow down the length of the digestive tract. Most of the digestion of the protein, fats and carbohydrate in the chyme is done by the enzymes in the duodenum, before the resultant mixture is passed further into the small intestine.

In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies.

The stages of mitosis were originally defined by cellular features observable through a light microscope.
a. True
b. False
Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
David comes into the emergency room late at night with a cut that will not stop bleeding. His mother, Rose, is worried that he has a bleeding disorder, just like his grandfather. The lab is closed, so the doctor cannot order a specialized coagulation test. However, the hospital does have a sample of blood from a classic hemophiliac. What is the simplest test the doctor could perform using David's blood to determine if it is missing factor VIII activity
Answer:
The doctor can mix a blood sample from the hemophiliac patient with David's blood.
Explanation:
This test is called Mixture Test and is performed quickly when there is no time to do more detailed and accurate tests. In the mixture text, two blood samples are mixed, where one is from a patient with hemophilia. when mixing the two samples, the doctor observes whether there were coagulation inhibitors in the patient's blood, and can then draw conclusions about the presence of hemophilia in the patient.

Which type of mining would NOT be used to mine coal
Answer:
Coal is mined in two different ways: from deep underground and in
strip mines. In both cases the land that is mined is leased by the coal companies, while the ownership remains in public hands. Deep mines are reached through a shaft into the ground, through which miners gain access to the coal seam and out of which comes the coal. Strip mines are used when the coal seam is near the surface. The topsoil and other overburden materials are removed by giant power shovels and piled out of the way. The shovels then dig out the coal. After the coal has been mined, there may be environmental reclamation to return the land to its original state, thus allowing others continued use of it for their own purposes. This involves refilling the hole, spreading topsoil, and then planting new vegetation on it.

A test tube is filled with water and a green plant called Elodea. When the plant is exposed to sunlight, it begins to produce bubbles. What is the most likely conclusion for the identity of the gas in the bubbles? Explain.
Answer:
The correct answer is - oxygen.
Explanation:
The experiment of a test tube and elodea plant in which a plant of elodea is placed in a test tube filled with water and exposed to the sunlight and one is placed in the dark. The plant that is exposed to the sunlight starts forming a gas that can be seen as bubbles in the test tube.
This experiment shows the process of photosynthesis that converts sunlight into glucose with the help of carbon dioxide and water and produces oxygen as a byproduct that releases from the plants.
Thus, the gas that forms in the test tube in the form of bubble is oxygen which is released in the process of photosynthesis.
