i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answers
Answer:
1.0 mol per dm^3 sodium chloride solution
Explanation:
The idea behind this question is that the water inside the potato stick would move into the surrounding liquid naturally if the density outside the stick is greater than it is inside. Therefore, the liquid that would most encourage the flow of water from the potato stick would be the moet dense liquid- which in this case, is 1.0 mol per dm^3 sodium chloride solution.

Which statement would be used in an argument against the use of human embryonic stem cells for therapy? A.Obtaining embryonic stem cells for use in therapy requires the destruction of embryos. B.Embryonic stem cells are limited in their ability to become different types of cells. C.It is difficult to grow embryonic stem cells in laboratory cultures, so they are not a practical choice for stem cell therapy. D.Embryonic stem cells originate in plants, so the likelihood of rejection by a patient's body is high.
Answers
Answer:
A.Obtaining embryonic stem cells for use in therapy requires the destruction of embryos.
Explanation:
Research involving human embryonic stem cells is subject to ethical and political debate because these investigations involve the destruction of human embryos. Stem cells have a series of advantages in the field of organ/tissue regeneration, to investigate the etiology of degenerative diseases, therapeutic cell cloning, etc. However, in many countries, the moment where life begins is a controversial point, and therefore this issue must be defined clearly before research.
The statement, that is, obtaining stem cells for utilization in therapy requires the destruction of embryos would be an argument against the use of human embryonic stem cells for therapy.
What are embryonic stem cells?
These are the pluripotent stem cells obtained from the inner cell mass of a blastocyst, that is, an initial stage pre-implantation embryo.
Research on human embryonic stem cells is subject to political and ethical debate, as these researches comprise the destruction and killing of human embryos. In the field of organ or tissue regeneration, the stem cells possesses an array of merits, they can play an essential role in therapeutic cell cloning, and to determine the etiology of degenerative disease.
But in many countries, the instance when the beginning of life has taken place is an ethical issue, thus, there is a requirement of clearly defining the issue prior to performing any kind of research.
Thus, the correct answer is option A.

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.
why saturated solution prepared at higher temperature gives crystal on cooling
Answers
Answer:
Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.
Explanation:
It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.

The broadest areas of the plant that absorb the most sunlight are the:
1. roots
2. stems
3. leaves
Answers
Answer:
Leaves
Explanation:
Plants grow broad leaves to absorb sunlight. This is extremely helpful because this helps plants make food through photosynthesis. Roots don't absorb sunlight. They absorb water and nutrients from the soil and carry it up through the stems. The stems then transports the nutrients throughout the plant.

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.

How did Mendel’s results from dihybrid crosses help him develop the law of independent assortment?
Answers
Explanation:
The out come that mendel's observed from dihybrid crosses confirmed that each trait could be described by a pair of factors that segregated to form progeny (his first law) and further suggested that factors for multiple traits segregated independently, thus forming the basis for mendel's second law of inheritance
Hope this will help you analyse your answer
Mendel crossed plants with two different features. He proposed the Law of Independent Assortment because the ratio showed that the inheritance of one trait is independent of the inheritance of another.
Mendel conducted studies to investigate the simultaneous inheritance of two distinct features, such as seed color and seed texture.
He combined plants that were different in both qualities, for example, a plant with smooth texture and yellow seeds crossed with a plant with wrinkled texture and green seeds.
The qualities Mendel was seeing separated independently of one another, indicating that the inheritance of one feature did not affect the inheritance of the other.
In other words, during gamete production, the alleles for seed colour and seed texture were assorting separately.
Thus, Mendel proposed the law of independent assortment, which is one of the cornerstones of inheritance, as a result of his dihybrid crosses and the observation of independent segregation of characteristics.

The Earth's tilt also causes the Sun's radiation to strike the _____ at different _____.
Answers
Answer:
hemispheres; angles
Explanation:
When a hemisphere—either northern or southern— is tilted toward the sun it has more hours of light compared to the hemisphere tilted away from the sun. Moreover, lower latitudes where the incoming solar radiation is more direct (angle closer to 90°) receive more radiation compared to higher latitudes where sunlight strikes at lower angles. The combined effect of more hours of daylight and more direct radiation in the hemisphere tilted toward the sun generates warmer temperatures compared to the hemisphere tilted away from the sun.
