Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
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.

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.

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?
PLZ HELP!!!! I NEED A ANSWER AND THE FIRST ONE TO ANSWER WILL GET A BRAINLIEST!!!!
Answer:
3miles per hour^2
Step-by-step explanation:
given data
initial speed u= 15mph
final speed v=45mph
time taken t= 10 seconds
Step two:
Required
acceleration a=?
applying the first equation of motion
v=u+at
substitute we have
45=15+a*10
45=15+10a
make a subject of the formula
45-15=10a
30=10a
divide both sides by 10
a=30/10
a=3miles per hour^2
Answer:
3m/s
Explanation:
15mph is the intial and 45 is the final subtract them and divide by ten
A manual contains instructions for how to build a variety of structures using a set of interlocking bricks. If this scenario is used as a model for genetic information, which statement is correct?
A, Each set of instructions is a protein
B, Each structure is a gene
C, The manual is a chromosome
Answer:
b
Explanation:
b Each structure is a gene
A manual which contains all the instructions for how to build a variety of structures using a set of interlocking bricks, in this model the manual is a chromosome. Thus, the correct option is C.
What is Chromosome?The chromosomes are the building blocks of the genetic code. A manual contains all the instructions regarding how to build blocks or proteins in case of body of an organism and is also used to make models for genetic information.
At the functional level of genes, DNA contains all instruction manuals that describes the cells information. These genes are transferred during the process of fertilization and are passed on to the offspring.
Therefore, the correct option is C.

Amoeba has been known as an unicellular organism in which all the activities has to be related to the life carried out in a single cell.
Multicellular organisms are made up of the eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.

What makes greenhouse gases different from other atmospheric gases?
Greenhouse gases reduce the amount of natural resources on Earth.
Greenhouse gases allow thermal energy to pass through the atmosphere and back out into space.
Greenhouse gases account for the direction in which water and air move.
Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.
Greenhouse gases are different from other atmospheric gases for the following reason:
Greenhouse gases trap thermal energy and reflect the sun’s harmful radiation back to Earth.Thus, the correct option is D.
What are greenhouse gases?Greenhouse gases may be defined as those gases that absorb infrared radiations which are competent to trap heat. Some examples of greenhouse gases are carbon dioxide, methane, CFCs, nitrous oxide, etc.
Greenhouse gases are more complex as compared to other gas molecules in the atmosphere. It has a structure that makes such gases more competent to absorb heat and radiate back to the Earth's surface. These gases trap the ultraviolet radiation from the sun and emit toward the earth's surface. Such gases are responsible for greenhouse effect.
Greenhouse gases are harmful to the environment as well as the health of living entities that constantly living in various ecosystems of the environment.
Therefore, the correct option for this question is D.
