Answer:
Some physical characteristics, such as the color of the human skin or eyes, are controlled by at least two genes. These traits are known as polygenic traits. The number of genes that determine the color of the iris is unknown, but the most significant of them are found in Chromosome 15 and they are named OCA2 and HERC2. These genes are associated with the production of melanin.
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic inheritance differs from Mendelian inheritance patterns, where traits are determined by a single gene. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

Which statement accurately describes radioactive dating?
A.Geologists use only one type of radioactive dating.
B.Geologists compare parent and daughter elements to determine rock type.
C.Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
D.Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Answer:
D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Explanation:
Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

The statement which best describes the relationship between DNA and genes is that Genes are segments of DNA. Thus, the correct option for this question is C.
What is DNA?DNA stands for deoxyribonucleic acid. It may be defined as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.
DNA is responsible for building and maintaining your human structure. While Genes are segments of your DNA, which give you physical characteristics that make you unique. Together, your body has a complete instruction manual that tells your cells how to behave.
Therefore, the statement which best describes the relationship between DNA and genes is that Genes are segments of DNA. Thus, the correct option for this question is C.

9. Mendel’s research led to several conclusions about how traits are passed through generations. Choose TWO of the conclusions from the bullet list below and provide evidence from THIS activity that supports this conclusion. (6 points)
Different forms of a gene account for variations in the inherited traits
An organism inherits two genes for each trait, one from each parent.
Some alleles are dominant over others for a given trait.
The two genes of a given trait segregate during gamete production.

Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.
Explanation
George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.
He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?
Answer:
3.5264 x [tex]10^{7}[/tex]
Explanation:
The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.
In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.
So the short ton produced will be
= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102
= 3.5264 x [tex]10^{7}[/tex] short ton.
Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

How would a lack of contact inhibition result in the growth and spread of cancerous cells?
Explanation:
Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells
Contact inhibition is the property of normal healthy cells where the cells cease growth after coming in contact with each other. A lack of this property results into uncontrolled growth of cells.
What is Contact inhibition?
Contact inhibition is the property of normal healthy cells which enables the cells to cease proliferation and growth when they come in contact with each other. This property is lost by the cell when the cells undergo malignant transformation. As a result, this leads to uncontrolled proliferation and solid tumor formation in the body.
In the in-vivo culture of cells, contact inhibition arrests cell growth and as a result, normal cells stop proliferating when they form a monolayer in the culture dish. Contact inhibition is a powerful anticancer mechanism which is lost in cancer cells.
