What is the impact of exposure to violence on development during middle childhood? How can exposure to violence play a role in bullying? Have you been a victim of bullying or a bully yourself? What is the best way to combat bullying?
Answer:
The exposure of a child with violence have been seen to have a number of negative influences on the child. One of these negative influences is the influence in the adaptability of the child and his academic success. Children who encounter violence are mainly subjected to low academic performance and have difficulty in adapting to schools. The exposure to violence disturbs the cognitive functioning of the child.
Children who are often depressed encounter more bullying from other people. The best way to combat bullying is to ask assistance from a higher authority such as a teacher.

Jupiter is a larger and more massive planet than Earth. If we could send a chicken to Jupiter, which statement below accurately describes the mass and relative weight of the chicken.
Question 3 options:
The mass and the weight of the chicken would increase.
The weight of the chicken would increase, but there would be no change in mass.
The mass of the chicken would increase, but its weight would decrease.
The mass of the chicken would change, but there would be no change in weight.
Answer:
The correct option is
b.) The weight of the chicken would increase, but there would be no
change in mass.
Explanation:
Jupiter is a larger and more massive planet than Earth.
The gravity of Jupiter is much more than Earth.
The weight of an object on a planet depends on the planet's gravity.
The weight of an object on a planet = (mass of the object) [tex]\times[/tex] (gravity of the planet)
Therefore the mass of an object is the same on any plant irrespective of the gravity of the planet.
Since the gravity of Jupiter is more than that of Earth then the weight of the chicken on Jupiter will be more than the weight of the same chicken on Earth.
Therefore the correct option is
b.) The weight of the chicken would increase, but there would be no
change in mass.
What effect does atmospheric co2 have on ocean acidification?
Answer: Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
Explanation:
Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate.
What is ocean acidification?About 30% of the carbon dioxide (CO2) released into the atmosphere is absorbed by the ocean.
The quantity of carbon dioxide absorbed by the ocean also rises as atmospheric Carbon dioxide levels rise as a result of human activities such as burning fossil fuels (e.g., automobile emissions) and altering land use (e.g., deforestation).
The concentration of hydrogen ions increases as a result of a series of chemical reactions that take place when Carbon dioxide is absorbed by saltwater. The effects of this process on the ocean and the marine life that inhabits it are extensive.
Therefore, Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate.

what is the phenotypic ratio that results from a dihybrid cross between two organisms and that are heterozygous for both traits
Answer:
The phenotype ratio predicted for dihybrid cross is 9:3:3:1.
Explanation:
A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. (Sorry if i Misspelled some words)
Final answer:
The phenotypic ratio from a dihybrid cross between two heterozygous organisms is typically 9:3:3:1, calculated using a Punnett square. This ratio applies when traits are independently assorted and show complete dominance. Deviations can occur with different interactions such as epistasis.
Explanation:
The phenotypic ratio that results from a dihybrid cross between two organisms that are heterozygous for both traits is typically 9:3:3:1. This ratio emerges from crossing individuals with the genotype AaBb x AaBb, where 'A' and 'a' represent the alleles of one gene, and 'B' and 'b' represent the alleles of a second gene. Both traits are independently assorted and show complete dominance.
To calculate the ratio, you would use a Punnett square to predict the genotype of their offspring. The resulting phenotypic ratio is:
9 showing both dominant traits (A-B-)3 showing the first dominant trait and second recessive trait (A-bb)3 showing the first recessive trait and second dominant trait (aaB-)1 showing both recessive traits (aabb)If there are deviations due to different assumptions about the phenotype of allele 'b' or other gene interactions, such as epistasis, the phenotypic ratio could be modified to 9:3:4, 12:3:1, 9:7, or 15:1.

Suppose the two possible alleles for the height gene are tall and short. If short is recessive to tall, provide the symbol representation and the phenotype for each of the genotype for this trait.
Phenotype - short , Tall
Genotype - tt (short) , TT or Tt (tall)
Explanation:
In Mendelian Genetics, Dominant traits are represented by capital letters and Recessive traits are represented by small letters.
So if height is the character considered, then the traits would be short and tall.
Tall is the dominant phenotype and short is the recessive phenotype.
The alleles of the gene for height are T and t.
The genotype for Tall trait is TT or Tt.
The genotype for short trait is tt.
Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.

Which of the following must be met for a scientifically valid sample? Subjects are selected:
Check ALL that apply
A. To represent the population
B. Based only on who volunteers
C. From the most conveniently available people
D. At random
Answer:
The correct answer is: A. and D.
Explanation:
In order to scientifically validate a sample, it is necessary that,The entire population under study should be considered to obtain an average or a mean data. If only a part of the population is considered then the result obtained would be a biased one. A biased data will not represent the entire population and so it would be incorrect.The sample choice done must be at random covering all the areas of the population to get the accurate result. This is because random selection lowers the possibility of getting biased.
A scientifically valid sample must be representative of the population, not based on who volunteers or conveniently available people, and should be selected at random. The correct option is A and D.
Explanation:To ensure a scientifically valid sample, subjects should be selected to represent the population, meaning they are a true reflection of the entire population. Selecting subjects based only on who volunteers or from the most conveniently available people may introduce bias into the sample. The best practice for selecting a scientifically valid sample is to choose subjects at random, which means every member of the population has an equal chance of being selected.

What would happen if diploid organisms reproduce by sexual reproduction without first producing sex cells through meiosis?
If no meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism.
Explanation:
If no meiosis takes place then the resulting zygote will be of double the number of chromosomes. The genetic makeup will change entirely. The process of meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.
The process of meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions.
In diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell is formed which gives rise to the organism having diploid cells.

Final answer:
The inquiry falls under the subject of Geography within the field of Geology, as scientists aim to determine if a meteor created a landform. Geological investigation is complemented by geographical techniques for explaining and predicting landscape changes.
Explanation:
The question pertains to a team of scientists working to determine if a meteor created a landform, which relates to the field of Geology. Geology is integral to understanding Earth's landforms, including those created by meteors. For instance, scientists employ geology to study the plate tectonics that form Earth's crust and contribute to the creation of various geological structures. Moreover, the history of meteorites, beginning in the late eighteenth century, shows that geologists and astronomers have long been intrigued by the extraterrestrial origins of certain stones that fall to Earth.
Understanding the effects of an asteroid impact, as well as analyzing patterns on Earth's surface and changes in the landscape, require knowledge of spatial science and geography. This includes plotting data on a map to verify clustering phenomena. Therefore, to ascertain whether a meteor has shaped a particular landform, scientists would utilize geological and geographical methods and data analysis.

What does natural resource management aim at?
Natural resource management aims at _________ management of resources.
Answer:
The correct answer is : Sustainable
Explanation:
Natural resources available on earth are the only source of energy to all living beings.They are of two types, Renewable and Non-renewable.Renewable resources are those that are present in ample amount and can regenerate themselves very quickly and hence do not get exhausted. Eg: Sun, Wind, etc.Non-Renewable resources are those that require a lot of time for their formation and if utilised at a rate which is much higher than its formation rate, can result in its exhaustion. Eg: Fossil fuels, Fresh water from glaciers.Natural Resources need to be utilised economically or in a sustained manner by the present generation to give the nature ample time to regenerate them and to ensure that some resources are retained for the future generations.Answer:

Groundwater is polluted by:
Chemical Fertilizers
Automobile exhaust
Fossil Fuel Burining
All of the Above
All of the above.
Explanation:
Ground water is polluted by Chemical fertilizers, Automobile exhaust as well as Fossil fuel burning.
Chemical fertilizers are directly causin ground water pollution. The excess of Chemical fertilizers on the land results in leaching of these chemicals into the ground water during rains.
But the Automobile exhaust and Fossil fuel burning are indirectly causing ground water pollution.
This can best be explained by considering the effects of acid rain on ground water. Acid rain causes harmful elements and certain toxic substance to dissolve in it and leach into the soil reaching the ground water. The Ground water acidification is also a consequence of acid rain.
Acid rains results from the presence of oxides of nitrogen, carbons, sulphur etc. These air pollutants are added to the atmosphere by automobile exhausts and fossil fuel burning.
So, we can conclude that automobile exhaust and fossil fuel burning may not be a direct cause of ground water pollution but they are indirectly responsible for ground water pollution.
