Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a technique that is used in forensic science to compare the DNA of the crime suspects by creating or separating DNA fragments or bands on the basis of size.
In this method, DNA samples placed in the indentations at one terminal side of a gel, and an electric current is passed through the gel. DNA fragments are a move toward the positive charge as it is a negative charge.
The correct answer is - Gel electrophoresis.
Name the four lapse rates and describe what each affects.
Dry rate is the rate at which a rising air parcel will change temperature with change in altitude if the air parcel is not saturated. Dewpoint rate is the rate at which the dewpoint changes with change in altitude. Wet rate is the rate at which a rising air parcel will change temperature with change in altitude after the air parcel has become saturated. Environmental rate is the rate at which the surrounding air changes temperature with change in altitude

Do all genes have a simple dominant/recessive relationship between two alleles? What is an example of a human trait that does have
this relationship between its alleles?
Answer:
Genes come in different versions, otherwise known as alleles, with dominant alleles being expressed over recessive alleles (one stronger than the other in terms of traits and etc). Recessive alleles are only expressed when no dominant allele is present. Color of the eyes, for example is allele A is brown color eyes and B is blue color eyes, and assume that A is the dominant then that relationship will prove A to be the simple dominant and B the recessive.

Pleiotropy and Polygenic traits are very easily confused. Please write a sentence describing the primary difference between these two inheritance patterns.
Answer:
Polygenic is a phenotype that is influenced by more than one gene, Pleiotropy occurs when one gene influences two or more unrelated phenotypic traits.
Explanation:
A polygenic trait is influenced by something, while Pleiotropy influences two or more phenotypic traits...so in simple words, one is influenced by something and the other influences different things

As you have been working in class today, the breathing center in the brain responds to the level of carbon
dioxide in the blood --- not the level of oxygen. What consequences does this have for people at high
altitudes.
Answer:
In the lungs breathing can be easier when not filling it with unnecessary toxins, the consequences of people at high altitudes slow asphyxiation if the altitude is high enough, headaches, hallucinations, blackouts and other symptoms if it's not as extreme.

This element can form a wide variety of substances, including long chains. The different substances it forms are central to the molecules found in living things. What element is this?
Answer:
The element is carbon
Explanation:
It has ability to catenate and it is a major constituent of all living matters
Carbon is the element that can form a wide variety of substances, including long chains. The correct option is C.
What is carbon?Carbon has the chemical symbol C and the atomic number 6. It is nonmetallic and tetravalent, along with each atom releasing four electrons to form covalent bonds.
It is in Periodic Group 14 of the periodic table. Carbon accounts for just approximately 0.025 percent of the Earth's crust.
Carbon's distinctive features make it an essential component of biological molecules.
Carbon forms covalent bonds with oxygen, hydrogen, and nitrogen to form the several molecules required for cellular function. Carbon's outermost shell contains four electrons and can form four bonds.
Many essential molecules in your body, such as proteins, DNA, RNA, sugars, and fats, are made up of carbon atoms.
Thus, the correct option is C.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.Why are genes contained in compact chromatin not expressed?
Answer: They are not expressed because A gene is dominant over the recessive gene.
Explanation:
The genes contained in compact chromatin not expressed are not expressed because a gene is dominant over the recessive gene.

Answer:

Explanation:
The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them hunting animals that ran faster than them and need for survival.
What is the difference between adaptation and natural selection?The action of natural selection consists of selecting individuals more adapted to a given ecological condition, eliminating those disadvantageous for that same condition. The most adapted expression refers to the greater probability that a given individual will survive and leave offspring in a given environment.
Natural selection occurs due to the need for survival and adaptation of species to the environment. It is through it that the most adapted species persist in the environment.

which response is a result of geotropism?
a) flower being produced
b) growing bigger leaves
c) roots growing downwards
d) seeds germinating
The response that is a result of geotropism is roots growing downwards. The correct option is c.
What is geotropism?Gravitropism is the coordinated process by which a plant grows in response to gravity acting on it. It is also found in fungi.
Gravity can be classified as either "artificial gravity" or "natural gravity." It is found in all higher and many lower plants, as well as other organisms.
Plant structures, such as roots, grow downward due to positive geotropism. Plants that grow upwards, such as shoots, exhibit negative geotropism.
Because roots grow in the direction of gravity, they exhibit positive gravitropism. Because plant shoots grow in the opposite direction of gravity, they exhibit negative gravitropism.
Gravity is detected by statocytes, which contain statoliths that sink inside the cell.
Thus, the correct option is c.
