If an object with 80 j of gravitational potential energy is raised twice as high, what would be its new gravitational potential energy?
a. 100 j
b. 160 j
c. Can't be calculated without
knowing its weight.
The gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy. And like this.
So, the answer is b. 160J

Explain how it is possible for nutrients to be transported to the cells of a flatworm with no circulatory system.
Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.
The maximum number of individuals that an environment can support is called the ___. A)population density B)Competition Factor C)density Independent factors D)carrying capacity
Answer:
D
Explanation:
Answer:
D
Explanation:
Population density is how dense a population is or how to spread out it is. Though carrying capacity is how much a thing such as land can carry such as lifeform and organisims.
What happens to groundwater when the rate of infiltration is less than the rate of water being pumped out of the ground? a. The water table is unchanged. b. The water table increases. c. The water table lowers. d. The water table is unaffected by infiltration.
Answer:
the answer is The water table lowers.
When the rate of infiltration is less than the rate of water being pumped out of the ground, the water table lowers. Thus, the correct option for this question is C.
What is a Water table?A water table may be defined as a boundary that lies below the ground and between the soil surface and the area where groundwater saturates spaces between sediments and cracks in the rock. The water that percolates down to the earth constitutes the water table.
According to the context of this question, if the rate of infiltration is less that means the percolated water is significantly less as compared to the water that is taken or being pumped out of the ground. In a more simple sense, water collected in the ground is less than the water taken from the ground. Due to this, the water table declines.
Therefore, when the rate of infiltration is less than the rate of water being pumped out of the ground, the water table lowers. Thus, the correct option for this question is C.

Answer:
The statistical study of populations and how they change over time is called demography. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.

Carbon dioxide is released by
Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.
Explanation:
How does the amount and type of fuel impact the distance a spacecraft can travel?
A space ship's momentum will continue to carry it forward indefinitely at a constant speed after the engines are turned off.
What do you mean by momentum?Momentum in a simple way is a quantity of motion. Here quantity is measurable because if an object is moving and has mass, then it has momentum. If an object does not move then it has no momentum.
Momentum, finance, refers to the capacity for a price trend to sustain itself going forward. Strong momentum can continue in an upward or downward trend, which can be confirmed by changes in trading volume and other technical indicators.
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum is affected by the parameters' mass as well as velocity.

List and describe the roles of the three different types of RNA involved in transcription and translation.
mRNA(messanger RNA)-results from transcription and contains the codons for protein synthesis .mRNA is synthesized by an enzyme called RNA-polymerase. It plays an important role in translation because it contains the codons that pair with anticodons from tRNA
t-RNA(transffer RNA)-carries the amino acids to the protein synthesis site(ribosome) and contains the anticodon that pairs with the codon from mRNA during translation
r-RNA(ribosomal RNA)- keeps the two ribosomal units together for the translation to take place
The three different types of RNA that are involved are:
mRNA(messenger)tRNA(transfer)rRNA(ribosomal)RNA'sThree major types of RNA are mRNA, or messenger RNA,which serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA,which serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled.

John weighs 725 N and is sitting at the top of the Tower of Terror, 60 m above the ground, by what factor will his gravitational potential energy change when he drops to 20 mo?
A. one-third
B. 2×
c. one-half
A. one-third
Because th height is directly proportional to the potential energy. So, when its height is reduced one - third (from 60m to 20m), then its potential energy will also be reduced to one-third.

Which of the following has not sped up the erosion of wetlands in coastal Louisiana?
A. dredging of thousands of kilometers of canals throughout the wetlands
B. the increase in acidity of the rainwater in the southeastern United States
c. the loss of barrier islands the cost of Louisiana
D. the 2010 Deepwater Horizon well blowout
Answer: B. the increase in acidity of the rainwater in the southeastern United States
Explanation:
The dredging of thousands of canals throughout the wetlands for easier navigation has sped up the erosion of Louisiana wetlands so option A is false.
The loss of barrier islands on the coast of Louisiana as a result of rising sea levels has also sped up the erosion of the wetlands as they are now more exposed to open water so option C is wrong as well.
The 2010 Deepwater Horizon disaster spilled so much oil that adversely affected the wetlands leading to their erosion so option D is wrong as well.
Option B is therefore right.

Bright purple true breeding plums(P) was bred with white true breeding plums
(p). The F1 generation were light lilac. One F1 individual for the above was then
used in a testcross. What proportion of the progeny will be white?
Answer:
The correct answer is - 50% or 1/2.
Explanation:
In the given case it is given that the true-breeding purple (P) plum bred with true-breeding white (p) plum and result in light lilac offsprings which suggests that there is incomplete dominance between these genes.
By the cross of these parent generation, there would be all heterozygous offspring that then used in testcross which is the cross between the dominant phenotype to the recessive plant so,
Gametes: P, p and p, p
P p
p Pp pp
p Pp pp
So the half or 1/2 proportion of the total offsprings would be white plums.
