Explanation: terrestrial planets are denser then the Jovian (Outer) planets since they are mostly made of rocky material, while the Jovian planets are gaseous.
Saturn, for example, would theoretically be able to float in water due to its low average density.
Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. A purple center outlined in black with two concentric black circles around the center, the inner circle having 2 small green balls on it and the outer circle having 8 small green balls on it. What experimental evidence led scientists to change from the previous model to this one?
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.

In human genetics, the allele for having freckles is inherited apart from the allele for having attached earlobes. Which one of Mendel's principles does this illustrate?
A- Principle of Alleles
B- Principle of Dominance
C- Principle of Independent Assortment
D- Principle of Segregation
Explanation:
The answer is B., because if freckles are a dominate trait between a female with freckles and a male with freckles, they're offspring will have a dominant trait of freckles..
Mendel's principle that describes this condition is known as the Principle of Independent Assortment. Thus, the correct option for this question is C.
What is the Principle of Independent Assortment?The Principle of Independent Assortment states that the two factors of each character separate out independently of the factors of the other characters at the time of gamete formation.
They get randomly rearranged in the offspring producing both parental and new combinations of new characters. According to the question, freckles are dominant over no freckles and unattached earlobes are dominant over attached earlobes.
This states that the factors of each character separate out independently. That is why the genes of these characters are not linked or associated with each other.
Therefore, the correct option for this question is C.

How do Punnett squares help predict the outcomes of artificial selection?
Punnett squares can be used to combine the alleles from the mother and the father to ascertain the likelihood as well as potential genotypes and phenotypes that a child may acquire from their parents.
What are Punnett squares?
The Punnett square is a tabular summary of possible combinations of maternal elapse with paternal. The percentages of phenotypes in a cross's progeny from known genotypes can be predicted using a Punnett square.
Based on the other genotypes involved in the cross, a missing genotype can be identified using a Punnett square. A Punnet square displays the potential gene combinations in the child inside the square, together with the genes (represented by letters) in the parent gametes along the top and left sides of the square.
Therefore, Punnett squares can be completed to determine the likely outcome of a cross.

If an animal fossil was found in a rock, what would be the best way to determine its absolute age?
*analyze the rock’s mineral composition
*take X-rays of the fossil and surrounding rock
*compare it to similar-looking fossils that have already been dated
*measure the ratio of a radioactive isotope and its decay product present in the rocks around the fossil
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
Explain How does the gradient of a river affect
its flow?
Explanation:
The flow of the river is dependent upon the position along the stream in terms of the gradient. Near the top of a high gradient, the flow will be less than that near the bottom. Likewise, the steeper the river's gradient, the faster the flow of water (due to the pull of water down the gradient by gravity).

Heredity is the passing on of traits from parent to offspring. Heritable information is important for life to continue. What is the role of meiosis in heredity?
Write your answer in the space below.
Answer:
Meiosis helps create more diversity and individuality in the genes of organisms.
Explanation:
Hope this is helpful, this is what I learned last year.
Answer:Sexual reproduction allows for the passing of traits from parent to offspring. In sexual reproduction, meiosis produces gametes that have chromosomes from the parents. The chromosomes carry genetic information. When the gametes fuse during fertilization, an individual with a unique combination of chromosomes or a unique genetic make up is formed.

Asthma is a chronic condition that affects a person's ability to breathe. Every year many people are rushed to the hospital because of severe asthma episodes. Air quality is a major trigger for asthma events in children aged 5 - 14. On a daily basis NYC posts air quality information to inform the city residents if it is a high risk day for asthma. Below you will find information summarizing persistent asthma in children aged 5 - 14 in NYC during 2013-2014. Pretend you are on a committee to create an action plan to improve air quality in NYC and use the data presented to select the target borough and neighborhood to begin your plan. Provide evidence to support your response.
Answer:
By using electric appliances.
Explanation:
By reducing the use of appliances that run with fuels such as stoves, fireplaces, gas or kerosene heaters, and oil and gas furnaces etc. These appliances produces nitrogen dioxide gas which is responsible for the pollution of air and leads to asthma disease. So as a committee member I will suggest to reduce the air pollution by using electric appliances instead of fuel appliance because electric appliances does not produce nitrogen dioxide gas.

A 20 N unbalanced force cause an object to accelerate at 1.5 m/s. What is the mass of the object?
Answer:
I believe it’s 13.33 m
Explanation:
Because a = Fnet / m
So if you plug the numbers in it’s : 1.5 m/s = 20n / m
Then you’ll want to cross multiply which it’ll be : 20n = 1.5m
Then you want to get m alone so you’ll divide 1.5 to both sides and that’ll leave you to
13.33 = m

Amy hikes down into the Grand Canyon to see Havasu Falls, a waterfall famous for its blue-green water and rock formations.
How does water shape Earth’s surface? What is the main way the hydrosphere interacts with the geosphere at Havasu Falls? Explain how this process forms waterfalls.
Basically when water goes over the earth it corrodes it and in that way shapes the earth's surface. The hydrosphere corrodes the gyoshere at Havasu Falls.
The hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.
What is Geosphere?
The geosphere is the layer of Earth which consists of solid rock and other rocky materials. In contrast it could be said that the geosphere is a part of the physical, solid Earth which excludes hydrosphere (i.e. oceans, lakes, and rivers) or the atmosphere (the layer of gases that separates the ground from space).
The term geosphere is basically the the crust portion of earth, as the crust elucidates the outer layer of earth's rigid portion.
The geosphere is basically all about processes, the rock cycle processes consisting of metamorphism, melting and solidification, weathering, erosion, deposition, and burial, these constant process are responsible for the recycling of rocks on Earth between sedimentary, igneous, and metamorphic states.
Thus, the hydrosphere is interacts with the geosphere at Havasu falls via Erosion. The erode of waterfalls softer surface of the rocks that leads to shaping the Earth's surface.

Explain why the size of a new moon would affect the appearance of a solar eclipse.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.
