is 3 249 because I add all of them together and I got 249
Answer:
(3) 249 grams
Explanation:
"The triple beam balance is used to measure masses very precisely; the reading error is 0.05 gram. With the pan empty, move the three sliders on the three beams to their leftmost positions, so that the balance reads zero. To find the mass of the object on the pan, simply add the numbers from the three beams." (Credit: SMU Physics Website)
This is how a triple beam balance works, so using this we can solve to find the mass of the object on the pan of balance. So we can add the 3 values.
200+40+9=249 grams
Technically the reading error is 0.05 g so I'm assuming you would subtract 0.05 g of some sort, but since there is no such decimal answer in the options given, we can conclude the correct answer would be number 3, 249 grams.

describe the effect of magnesium deficiency on the transport of sucrose out of the leaves and the sucrose concentration out of the leaf
Answers
Answer:
The impact of diminishing the convergence of magnesium salt on the development of S.polyrhiza is because the low mg accessibility keeps an eye on troublesome sucrose exportation, making leaves hold sucrose three to multiple times more than the leaves of plants that get Mg in satisfactory inventory, showing that the inadequacy of this supplement causes extreme hindrance of sucrose transport.

Do either of your diseases in part A have the same pattern of inheritance as the model colorblindness mutation you made?How do you know?
Answers
Answer:
Autosomal dominant pattern.
Explanation:
If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.

Answers
Answers
-Worldwide sea level increased
-river plains drowned
Explanation
Glaciers are large blocks of ice and with all the ice melting the water levels rose worldwide. (Correct Answer)
When sea levels rose it caused river plains to be flooded. (Correct Answer)
Glaciers are made from freshwater so when they melt the salinity in estuaries does change. (Not a correct Answer)
Erosion definitely affected river valleys. Alpine glaciers create valleys and even help erode valleys. With Alpine glaciers melting this slows the process of that erosion and with them melting the river valleys will eventually flood. (Not a correct Answer)

Answers
True these are both examples of food produced through alcoholic fermentation.
What is Alcoholic fermentation?
The chemical reaction that produces alcohol is known as alcoholic fermentation. In essence, beer, wine, sake, and cider all begin with yeast eating a type of sugar, which is the basis for this process.
Even hard liquors, such as your preferred tequila, begin with a straightforward alcoholic fermentation.
Alcoholic fermentation produces three primary byproducts. Alcohol, which has historically been a crucial component of beer, wine, and hard cider, is one of them, which is not surprising.
Therefore, True these are both examples of food produced through alcoholic fermentation.

describe about nutrition in human being
Answers
Answer:
Nutrition In Human Beings. Nutrients are the substances in food that maintain the body and make it work. Most of what one eats is made up of carbohydrates, proteins, and fats. Nutrients needed in smaller amounts, but still vital, are vitamins and minerals.
Explanation:
Hope it's answer you plz mark as Brainlist
The human being has a heterotrophic nutrition. Nutrition is realised by digestion. Digestion can be either intracellular or extracellular. Intracellular digestion occurs for example when white blood cells consume pathogens or dead tissue. Extracellular digestion occurs in the digestive tract. Digestion can be either mechanical(chewing) or chemical(hydrolysis-a process in which for every broken bond a water molecule is added).
The main types of nutrients are:
Carbohydrates that are mainly used for energy. In the digestive tract there are different enzymes that hydrolyse the carbohydrates to monosaccharides.
Carbohydrate----(enzyme)--->monosaccharide
Proteins play an important structural and functional role in the body. There are specific enzymes that digest them. They are broked down to amino acids.
Protein-------(enzyme)---->amino acid
Lipids store energy. There are enzymes that break lipids down to fatty acids and glycerol.
Lipids----(enzyme)--->fatty acids+glycerol
Vitamins help the metabolism and are not chemically processed in the digestive tract nor are minerals or water.

How does the structure of DNA direct the formation of proteins?
Answers
Answer: During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. ... A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
The sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.
What is the process of protein formation?The process of the creation of protein molecules is called protein biosynthesis. Amino acid synthesis, transcription, translation, and post-translational events are the steps that are involved in protein synthesis. In the case of amino acid synthesis, a set of biochemical processes happen and they produce amino acids from various carbon sources like glucose.
In the case of biological systems, protein synthesis happens inside the cell. In the case of prokaryotes, it occurs in the cytoplasm. In eukaryotes, it happens in part in the nucleus and partly in the cytoplasm.
The transcript is formed in the nucleus and leaves the nucleus to reache the ribosomes and it is translated there and forms a protein molecule that has a specific sequence of amino acids.
The creation of proteins by cells uses DNA, RNA, and various enzymes. Usually, it includes the events like transcription, translation, and post-translational events. These are protein folding, modifications, and proteolysis.
Therefore, the sequence of nucleotides of DNA directs the formation of the structure of proteins. The information stored in the DNA is transferred to the RNA by transcription and the RNA forms the proteins.

Answer:
adherence of phagocytes to the lining of blood vessels
Explanation:
The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.
Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.

Answer:

It is a renewable energy.It is eco friendly.It is derived from biomass.Example :- Ethanol, Biodiesel etc.Equipment required: One or more buckets of water (or access to a garden hose connected to a water supply).
Pour one or two buckets of water (or run water from a garden hose) on bare ground (grass or soil is OK). Observe how the water moves. Some of the water may soak into the ground and some may flow over it. Pour a few more buckets (or run more water from the garden hose) over the same area and observe any differences in the behavior of the water. Does it still soak into the ground? Discuss how the moisture conditions in the soil will affect how much water gets absorbed. Would water be more likely to run off after the ground has been saturated by a heavy rainstorm? Discuss what happens to the water that gets absorbed into the ground.
Repeat the demonstration on a paved surface such as a driveway or sidewalk and document the differences. With no soil to absorb this water, what would happen in a heavy rainstorm? How would an engineer in charge of a city’s flood control system prepare for the runoff generated on paved parking lots and roads in a heavy rainstorm?
Answers
Answer:
No water will be soaked by the soil if it has saturated condition.
Explanation:
If the soil does not reached to its saturated point so the soil will soak the water while on the other hand, if the soil reached to its saturated point so it will not absorb the water. If soil has more water so it will not be able to absorb more water. Yes, water will be more likely to run off after the ground has been saturated by a heavy rainstorm and the water absorbed by the soil remain in the soil for the plant while the large quantity of water percolates down and reach the water table. With no soil to absorb water, the water goes to rivers and streams when a heavy rainstorm held. The engineer has to built a well drainage system in order to remove runoff water from the roads and pavement and avoid flood condition.
