predict whether a pot of water heated from the top would boil more quickly than a plt of water heated from the bottom. Explain your answer.
Water will boil faster when it is heated from the bottom rather than when it is heated from the top.
The boiling of water occurs due to convection currents. Heavier particles moves from upwards and travels downwards and then they are replaced by lighter particles traveling upwards. This is called convection currents.
As such, water will boil faster when it is heated from the bottom rather than when it is heated from the top.

What might be the result if you shuffle the order of bases in an organism's DNA
molecules?
Answer:
It would have disastrous consequences on the viability of the individual
Explanation:
The genome can be defined as the genetic material of an organism, which is composed of DNA molecules named chromosomes whose building blocks are four different nucleotides: Adenine, Thymine, Cysotcine and Guanine. The order of these nucleotides specifies the information contained in the chromosomes and, ultimately, in the genome. The genes, which are recognized to be the basic units of inheritance, are genetic sequences composed of ordered nucleotides along the chromosomes. During transcription, a gene encodes different RNA codons (for example, start and stop codons) which are specified by the order of the nucleotide sequence. Finally, the order of the RNA codons will be critical to specify the polypeptide chain during the translation from RNA to protein.

what are the arguments against regulations aimed at reducing water pollution
Answer:
There are numerous forms of pollution and environmental problems that human beings have been causing since the beginning of the industrial revolution and, in particular, since the second half of the last century. Pollution without borders associated with all human activities and which, along with other serious problems, is degrading all ecosystems and contributing to climate change whose consequences we are already experiencing. The costs of this environmental degradation have not been taken into consideration until recently, but it is beginning to be understood that they must be incorporated in the evaluation of any project; They cannot be “outsourced”, as has been done, because it is absolutely unsustainable.

Explanation:
Why doesn't being surrounded by gallons of water in a swimming pool cause sodium imbalances and/or water intoxication?
The pool water is isotonic with your internal body fluids.
It is impossible to sweat in a swimming pool; therefore, your body loses no sodium.
Your skin is not as permeable as the lining of your digestive system.
The chlorine in the pool water prevents your body from losing sodium to the surrounding environment, or Swimming in pool water can cause a sodium imbalance; this is why swimming in the ocean is preferable.
Answer:
The correct answer is: Your skin is not as permeable as the lining of your digestive system.
Explanation:
Pool water is mostly composed of water with some chlorine in it. This is why it could never be true that pool water is isotonic with a person's internal fluids, where half of the osmotic pressure is given by sodium. For pool water to be isotonic with our internal body fluids, it should be a 0.9% NaCl solution.
The chloride in the pool water has no special properties that make your body not lose electrolytes.
The reason why swimming in a pool doesn't cause sodium imbalances is because the skin is not as permeable as the lining in our digestive system. We don't absorb water or ions through our skin. The only way we can get more water and electrolytes in our bodies is by ingesting them when drinking water or eating food. Then, our digestive system absorbs it, and after that, the kidneys dispose of the excess water or electrolytes.

A common method for analyzing microtubule motor activity is to attach them to a glass coverslip (the tails stick very well to glass) and then incubate with microtubules, which will settle on them and then "glide" across the surface of the coverslip as the heads of the motors propel them. This is easily observable in the light microscope. In an assay such as this, how can one determine the directionality of the movement of the microtubules (plus- or minus-ended)? Assume that you do not know if the motor is a plus- or minus-end motor prior to the experiment.
Answer:
Explanation:
Microtubules are integral part of the cytoskeleton of eukaryotic cells, responsible for maintaining the shape of the cell. They are involved in intracellular trafficking by forming veritable "rails" along which motor proteins move and transport various organelles.
In analyzing microtubular motor activity, the plus (+) end and the minus(-) end proteins can be marked with non-identical fluorescent proteins, followed by observing it under the fluorescent microscope. From observation, the presence of motility of the fluorescent dye helps to determine if the motor is plus or minus end.
Where would a new star most likely form?
Answer:
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
Most galaxies have stars distributed throughout them that are born within dust clouds.
What are stars?Any large, gaseous celestial body that is self-luminous and emits light as a result of its own internal energy sources is a star.
Stars are created when a very huge cloud of gas and dust in space slowly contracts under the force of gravity.
The presence of gas and dust clouds is relatively widespread, and our knowledge of the Milky Way Galaxy's star-forming regions is extensive.
Stars are born within dust clouds and are dispersed throughout the majority of galaxies. Most galaxies have stars distributed throughout them that are born within dust clouds.
The Orion Nebula is a well-known illustration of a dust cloud of this type.
Deep within these clouds, turbulence creates knots with enough mass for the gas and dust to start collapsing under its own gravitational pull.
Thus, this way, the stars are formed.

How does the structure of proteins related to their function?
Answer:
Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.I hope this helpsThe structure of proteins depends upon the sequence of amino acids joined together. The sequence of amino acids changes the function of proteins.
What are proteins?Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.
The relationship between a protein's structure and function is direct. The function of a protein is determined by its unique form.
The protein becomes denatured and ceases to function as intended if the three-dimensional structure of the protein is altered as a result of a change in the structure of the amino acids.
Therefore, the order in which amino acids are linked together determines how proteins are structured. The order of amino acids alters how proteins work.

Fahd is trying to write a focused scientific question. He writes, “Does the material something is made of affect its density?” How could Fahd’s question best be rewritten?
Answer: So basically we have to know does the material's characteristics/compositions affect its density?
Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.

why does the bread easily get molds than the rice
Answer:
The sugar content
Explanation:
Bacteria are attracted to sugar, so maybe, they try to get the sugars and mold the bread.
Bread can easily get molds than the rice because of the following:
Mold are micro organisms that grow on the surface of left over food or food that are not properly preserved.
Although preservatives prevent bread from molding quickly but Bread will tend to always mold, unless it is kept in the fridge.
Bread that are kept in a place that is cool will often last for days compare to bread that are kept in a place with heat as heat will make the mold to quickly grow on the bread .
White rice that is dry can last upto 3 years or even more than if they are store in a room temperature.

Read the excerpt from Team Moon. The heavier the spacecraft, the harder it is to launch. And fuel is heavy. So it was critical to pinpoint the fuel needed, add a cushion, then take no more than necessary. But now, because the landing was taking far longer than planned, the fuel was almost gone. Mission Control wanted Neil to take as much time as he needed and fly the LM as near empty as possible only because they wanted him to make the landing. But if he ran out of fuel above the surface, in all likelihood the LM would crash onto the moon. So they were trying to time it to the last possible second before calling an abort—calling off the landing. Why does the author use a problem-solution text structure in the paragraph?

Explanation:
The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.
Everyday has an equal distance measured by the student all through the week.
Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.
This means that, as time (days) increased, distance measured each day remains the same.
