1. What is the Potential energy of an object that has a mass 10 kg and has a height of 50
(m)?
Answer:
24
Explanation:
A scientist could best determine which ion (F-, Cl-, Br-, or I-) produced the greatest electrical potential in the Experiment by comparing the electrical potential that develops between ice and:
a solution of each sodium salt at the same concentration.
a single sodium salt solution at different concentrations.
a single sodium salt solution at different temperatures.
droplets of sodium salt solutions at different collision rates.
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

Explanation:
Which step happens first in DNA replication?
Answer:
Initiation
Explanation:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).

EVALUATE The following statement. Erosion is a constructive process and deposition is a destructive process. Do you agree? Explain. :)
Answer:
Erosion is always destructive
Explanation:
This statement is not true as erosion is always a destructive process.
What is erosion?Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. It is an action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. It is distinct from weathering which involves no movement.
Moreover, it is the movement of particles away from their source. Example of erosion: Wind carries small pieces of rock away from the side of a mountain. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions.
Hence, erosion is a destructive process while deposition is a constructive process.

What factors are important in judging how helpful an energy resource is to us?
The factors which are important in judging the help fullness of energy resources to us are demand, storage of gas, weather forecast, nuclear and coal.
What are the important factors in judging the helpfulness of energy?The first factor is demand for heating, cooling, light, and processes varies in response to demand in terms of economic, technological, and efficiency measures. The second factor is Gas Storage and this has a term for energy “inventory” (since you can’t store electricity), i.e. the difference between supply and demand. Gas injections and withdrawals are announced weekly, and prices adjust accordingly.
The third factor is weather forecasts that is used to predict the weather events which are important considerations, affecting spot market prices and short-term contracts. Weather the forecast becomes reality is less critical to longer-term prices and last is generation changes while seemingly more localized, these changes can have a broad effect on the markets.
Nuclear retirement of older plants as they require re-licensing can cause fluctuations and coal plant conversions to natural gas to avoid scrubbing-technology costs can also cause fluctuations.
Therefore, The factors which are important in judging the help fullness of energy resources to us are demand, storage of gas, weather forecast, nuclear and coal.

Look at the food web. In your response, answer the following questions
correctly for full credit: a) Identify the producers, primary consumers, and
secondary consumers in the ecosystem. b) What would happen if all the
hawks in this ecosystem were to die from an illness? c) Why would you
expect there to be fewer foxes than caterpillars in this ecosystem? d)
Which organism would have the smallest population? (8 points)
Answer:
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers.
B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash.
C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population.
D) The hawk has to be the smallest population.
Explanation:
What would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells

In Mendelian case, the offpspring will take on the pheonotype of the parent that donates the dominant allele True Or False. I'm giving 65 points for this
Answer:
True
Explanation:
According to Mendelian's law of inheritance, the dominant allele is the allele that is expressed in an individual while the recessive allele are usually not expressed in the phenotype of an individual.
If a parents is dominant for a particular allele of tallness and recessive for a particular allele of shortness it is observed that the dominant allele is what is expressed in the phenotype of the offspring and inherited in simple Mendelian fashion by the offspring.

Evaluate the neighbor's arguments in the following scenario. Are there facts he is overlooking?
An elderly neighbor says today's girls are less mature than they used to be. He says it used to be that by the time a girl had a mature body, she had
a mature brain to go along with it. The neighbor argues that it all comes down to bad parenting and too much television.
Answer:
He is trying to explain that girls in his day had more respect for their self than they do not
Explanation:
They copy what they see on tv, school,and friends
Answer:
First of all, every child develops and matures on their own pace (within a certain range) and we can't compare one person to another. Secondly, in general, girls are reaching puberty earlier than they used to, which may stem from nutritional or environmental influences. For example, in 1900, the average age of puberty for girls was fifteen; today, it is twelve and a half. Moreover, attaining puberty or having a mature body doesn't result in a mature or fully developed brain. The brain continues to develops on its own pace from the rest of the body, until into adulthood to the age of twenty-five.
