List and explain 3 mutations that allow cancer cells to occur
Answer:
Germline mutations, Chromosomal alterations and Point mutations.
Explanation:
Mutations in genes is responsible for causing cancer because it accelerate rate of cell division or inhibiting normal controls. Germline mutations, Chromosomal and Point mutations are the three types of mutations which causes cancer cells to develop. Germline mutations causes inherited cancer because the mutations occur in sex gametes means cancer disease inherited from parents to offspring while Chromosomal and Point mutations occur in the body not in the sex cells.

A genetic mutation causes a squirrel to be born with much darker fur than its parents.
How will this mutation most likely affect the squirrel population?
Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait.
Because the trait was caused by a mutation, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is unfavorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
Answer: If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
The mutation most likely affects the squirrel population if the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. The correct option is D.
What is mutation?A mutation is a change or modification in the DNA or gene sequence of the organism. The modification is done due to mutagens. These mutagens delete or insert or replace the bases and cause differences.
Here, due to mutation, the color of the squirrel changed to black, so if the gene of black color will be transferred to future generations, it can be dominant or recessive.
Thus, the correct option is D, If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.

Answer:
Sprain
Explanation:
A sprain occurs when a joint is weakened by the advent of some mechanical forces which cause twisting of the joints. This results in partial dislocation of one of the bones at the joint. The effect of strain can range from mild to severe depending on the amount of damage that is being caused at the joint region.

Answer:
$150, $200
Explanation:
A schedule that shows relationship between quantity supplied and quantity demanded is used to estimate the equilibrium quantity and price where there is a balance between the buyer's willingness to buy and the seller's willingness to sell.
Below this equilibrium point there is excess of quantity demanded over limited supply.
Above equilibrium there is excess supply and less demand.
According to the given schedule the equilibrium price is $100 where demand and supply are both 300 units.
The prices at which there are excess supply is given below
At $150 400 units is supplied against 250 units demanded
At $200 500 units are supplied against 0 units demanded

Put the last 6 (Creep to Avalanche) in order from Fastest to Slowest.
Answer:
creep, solifluction, slump, earthflow, mudflow, debris avalanche, rockfall
Explanation:
Mass movement also known mass wasting is the motion of rock, regolith (loose mixture of soil and rock particles that covers the earth's surface), snow, and ice down a slope. Based on increasing speed of movement, the given mass movement processes are as follows:
Creep- this a very slow, usually continuous movement of regolith down slope.
Solifluction - this is a sediment flow. A sediment flow is a mixture of rock, regolith with some water. The rate solifluction is measured in centimeters per year. It occurs at a faster rate than than creep.
Slumps - is a type of mass movement whereby there is a downward rotation of rock or regolith along a curved surface producing depressions or scars on the slope. It occurs at a faster rate than solifluction.
Earthflows - they usually occur with heavy rains and occur at a much faster rate with velocities between several centimeters per year and hundreds of meters per day.
Mudflows- are a highly fluid mixture of sediment and water which usually result from heavy rains in areas where there is an abundance of loose sediment. These sediments are picked up by flowing streams of water. Mudflows occur at high velocities and can travel long distances.
Debris Avalanches - These are very high velocity mass movements that result from the complete collapse of a mountainous slope. Earthquakes and volcanic eruptions usually cause debris avalanches. Avalanches involving snow only is known as snow avalanches.
Rock Falls - Rock falls occur when a piece of rock which may be large or small on a steep slope comes loose and falls down the slope. On its way down it may dislodge other rocks which also fall down the slope. Rock falls are the fastest of the six types of mass movements stated.

In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.
Which statement about the event represented in the diagram is valid?
Answer:
"The genes for all organisms are composed of the same building blocks"
Explanation:
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic material
this results in the recombination of the genetic material and creates a new genetic combination.
Thus, genetic variations occur which can be beneficial to the offspring.
Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.

What does this common homeostatic mechanism indicate about humans and horses? A. They evolved the trait simultaneously . B. They are the two species that regulate body temperature . C. They share a common ancestor . D. They evolved in different environments .
Answer:
The answer is option C "They share a common ancestor"
Explanation:
Homeostasis can simply be defined as the processes which animals needs to undertaken or the conditions animals exhibits to maintain a balanced or stable condition in the body system that are significant for the survival of the animal.
One of the ways animals maintain a stable state is regulating the body temperature through sweat and this process is peculiar to both Humans and Horses because the share a common ancestor considering Homeostasis to be a mechanism for evolution.
