When a chemical reaction occurs, what happens to the atoms of the two substances? Provide an example from the Sim (on Amplify) as evidence to support your answer.
When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Which of the following problems would be a direct result of humans building along the ocean shore zone?
A. the erosion of the sand and soil from the shoreline
B. sand dunes and vegetation being disturbed
C. the movement of sand from one place to another
D. sand being washed away over long periods
Answer:
I think it is B.
Explanation:
The erosion of the sand and soil from the shoreline would be a direct result of humans building along the ocean shore zone. When humans build structures along the shoreline. This can lead to increased erosion of the shoreline and loss of the beach.
Building along the ocean shore zone can have several impacts on the natural environment. One of the direct impacts is the erosion of the sand and soil from the shoreline. This occurs because construction can disrupt the natural processes that maintain the beach, such as the movement of sand and the protection provided by vegetation.
For example, building seawalls or other structures can prevent the natural movement of sand and sediment along the beach. This can lead to erosion of the shoreline, as the sand is no longer able to accumulate in areas where it is needed to protect the shoreline. These plants help to hold the sand in place and protect the beach from erosion.

Write TWO examples of Newton's third law in "The Martian."
For every action force, there is an equal and opposite reaction force.
Answer:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down. Another action would be the bomb making the whole in the airlock door which will have a reaction of the ship slowing down
Explanation:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.
What is Newton's Third law?Newton's Third Law is defined as when two bodies come into contact, they exert forces on one another that are both equal in strength and directed in opposing directions.
Ball bouncing: When a ball strikes the ground, it exerts action force on the surface. The ball bounces back as a result of the ground's reaction force. A bird's wings act as an action force, pushing air downward, and act as a reaction force, pushing the bird upward.
Thus, Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

This passage describes the xeroderma pigmentosum trait in humans:
Xeroderma pigmentosum is a condition that causes skin to be easily damaged
by sunlight. Humans with xeroderma pigmentosum avoid exposure to sunlight by
wearing protective clothing, using sunscreen, and not going outside during the
day.
In a group of humans, some individuals have xeroderma pigmentosum and others do not. In
this group, the gene for the xeroderma pigmentosum trait has two alleles. The allele E is for
not having xeroderma pigmentosum, and the allele e is for having xeroderma pigmentosum.
Hunter, a human from this group, does not have xeroderma pigmentosum. Hunter has two
alleles for not having xeroderma pigmentosum.
Based on this information, what is Hunter's genotype for the xeroderma pigmentosum gene?
Ee
EE
not having xeroderma pigmentosum
having xeroderma pigmentosum
Answer:
Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight. This condition mostly affects the eyes and areas of skin exposed to the sun. Some affected individuals also have problems involving the nervous system.
The signs of xeroderma pigmentosum usually appear in infancy or early childhood. Many affected children develop a severe sunburn after spending just a few minutes in the sun. The sunburn causes redness and blistering that can last for weeks. Other affected children do not get sunburned with minimal sun exposure, but instead tan normally. By age 2, almost all children with xeroderma pigmentosum develop freckling of the skin in sun-exposed areas (such as the face, arms, and lips); this type of freckling rarely occurs in young children without the disorder. In affected individuals, exposure to sunlight often causes dry skin (xeroderma) and changes in skin coloring (pigmentation). This combination of features gives the condition its name, xeroderma pigmentosum.
People with xeroderma pigmentosum have a greatly increased risk of developing skin cancer. Without sun protection, about half of children with this condition develop their first skin cancer by age 10. Most people with xeroderma pigmentosum develop multiple skin cancers during their lifetime. These cancers occur most often on the face, lips, and eyelids. Cancer can also develop on the scalp, in the eyes, and on the tip of the tongue. Studies suggest that people with xeroderma pigmentosum may also have an increased risk of other types of cancer, including brain tumors. Additionally, affected individuals who smoke cigarettes have a significantly increased risk of lung cancer.
The eyes of people with xeroderma pigmentosum may be painfully sensitive to UV rays from the sun. If the eyes are not protected from the sun, they may become bloodshot and irritated, and the clear front covering of the eyes (the cornea) may become cloudy. In some people, the eyelashes fall out and the eyelids may be thin and turn abnormally inward or outward. In addition to an increased risk of eye cancer, xeroderma pigmentosum is associated with noncancerous growths on the eye. Many of these eye abnormalities can impair vision.
About 30 percent of people with xeroderma pigmentosum develop progressive neurological abnormalities in addition to problems involving the skin and eyes. These abnormalities can include hearing loss, poor coordination, difficulty walking, movement problems, loss of intellectual function, difficulty swallowing and talking, and seizures. When these neurological problems occur, they tend to worsen with time.
Researchers have identified at least eight inherited forms of xeroderma pigmentosum: complementation group A (XP-A) through complementation group G (XP-G) plus a variant type (XP-V). The types are distinguished by their genetic cause. All of the types increase skin cancer risk, although some are more likely than others to be associated with neurological abnormalities.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
