Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.
Alison finds the total mass of a sample of baking soda, a balloon, and a glass container with vinegar in it. She adds the baking soda to the vinegar and immediately places the balloon over the mouth of the container. After the reaction is complete, she again finds the total mass of the system.
Which statement is true:
1. The mass does not change because chemical changes observe the law of conservation of mass.
2. Mass is gained during the reaction because a chemical change is taking place.
3. Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
4. Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.
Answer:
2. Mass is gained during the reaction because a chemical change is taking place

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!
Answer:
Inertia- the tendency of an object to resist a change in velocity
Explanation:
Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.
Answer:
inertia is the constant state of movement so seatbelts stop that when you stop the car.

How do you know that an object in space is moving through the sky?
Answer:
See explanation
Explanation:
Objects in the sky could really be moving. You and tell if you stand vary still and focus on the object. Or they reflect our motion through space, which makes it look like the object is moving.

1. How do the Punnett squares for a monohybrid cross and a dihybrid cross differ?
2. What are the genotypes of gametes of an AaBb self-pollination?
3. Mendel carried out a dihybrid cross to examine the inheritance of the characteristics for seed color and seed shape. The dominant allele for yellow seed color is Y, and the recessive allele for green color is y. The dominant allele for round seeds is R, and the recessive allele for a wrinkled shape is r. The two plants that were crossed were F1 dihybrids RrYy. Identify the ratios of traits that Mendel observed in the F2 generation. Create a Punnett square to help you answer the question.
Answer:Biologists use a diagram called a Punnett square, to help predict the probable inheritance of alleles in different crosses.
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

What causes days to be warmer on one part of Earth than on another?
A. the number of cars on the road
B. the rotation of Earth
C. the speed of Earth in its orbit
D. the angle at which the sun strikes Earth
The days to be warmer on one part of Earth than on another because the angle at which the sun strikes Earth.
What would cause earth to have a shorter day?As the Earth moves around the sun during a year, the northern half of the Earth is tilted towards the sun in the summer, making daytime longer than night.

How does the Coriolis effect impact the Gulf Stream and the Brazil Current?
It turns the Gulf Stream southwest and the Brazil Current northeast.
It turns the Gulf Stream northwest and the Brazil Current northeast.
It turns the Gulf Stream northeast and the Brazil Current southwest.
It turns the Gulf Stream northeast and the Brazil Current northwest.
Answer:
The Coriolis effect acting on these currents causes northern hemisphere gyres to move in a clockwise direction and southern hemisphere gyres to move in a counterclockwise direction.
Explanation:
The Coriolis effect does the impact on the Gulf stream and the Brazil Current by turning the Gulf Stream towards northwest and Brazil Current northeast. Thus, the correct option is B.
What is Coriolis effect?The Coriolis effect results in bending the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form the circular patterns. The direction in which they spin depends upon the hemisphere in which they are present.
Coriolis Effect is named after the French mathematician and physicist Gaspard-Gustave de Coriolis. It affects the weather patterns of an area, it affects the ocean currents, and it also affects air quality.
Therefore, the correct option is B.

In a particular breed of rabbits, fur color is gray or white. If a rabbit with gray fur and a rabbit with white fur reproduce and the offspring all have gray fur, what can you infer about the gene for fur color?
Answer:
D
Explanation:
The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.
What is dominant gene?One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.
Dominant describes the relationship between two genetic variants. If one is in charge, the other must be subordinate. Then it is referred to as recessive.
A dominant gene, or dominant form of a gene, is a specific variant of a gene that expresses itself more powerfully on its own than any other version of the gene that the individual is carrying—in this example, the recessive—for a variety of reasons.
Therefore, The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.
