Answer:c
Explanation:
The correct association that links the time period with the location of the fossils is as follows:
Pennsylvanian → eastern and western Virginia
Cambrian → throughout southern Virginia
Tertiary → eastern Virginia
Quaternary → eastern and western Virginia
Time periods and fossil sites are linked: Eastern and western Virginia have Pennsylvanian fossils. Southern Virginia has Cambrian fossils. Eastern Virginia has Tertiary fossils. Eastern and western Virginia have Quaternary fossils.
Geological evidence and fossilized remains in specific places and chronological periods support these relationships. Understanding fossil distribution over time and region helps reveal Earth's geological history and biological evolution.

Which forensic scientist's work involves knowing how a body decomposes?
Forensic sociologist
Forensic psychiatrist
Digital forensics expert
Forensic entomologist
Answer:
Forensic anthropology or forensic entomologist.
Explanation:
The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. Would the use of created wetlands be considered biotechnology
Answer:
Yes; the use of created wetlands would be considered biotechnology.
Explanation:
The created wetlands will employ the use of scientific tools and techniques, which will largely modify the plants, animals, and microorganisms in the Gulf of Mexico's dead zone. Generally, it has been established that biotechnology allows farmers to grow more food with environmentally sustainable farming techniques, which also improve soil conservation.
Answer:
Yes, the use of created wetlands would be considered biotechnology.
Explanation:
Biotechnology uses biological systems and living organisms to develop and create different products. The new wetland that they create will be made with the usage of scientific tools and techniques in order to replicate an already existing biological system. It will have very modified plants, animals and other organisms in the Gulf of Mexico's dead zone.

The border between two tectonic plates lies below the state of California. The interaction of these two plates results in which of the following?
a.) Mild Climate
b.) Rich, fertile soil
c.) Frequent earthquakes
d.) Occasional wildfires
Answer:
Frequent Earthquakes
Explanation:
californication
The interaction of these two plates results in frequent earthquakes.
What is an earthquake?An earthquake is a sudden and intense shaking of the ground caused by the movement of tectonic plates in the Earth's crust. Earthquakes can result in damage to buildings, roads, and other structures, as well as cause landslides, tsunamis, and other natural disasters.
They are caused by the release of energy from tectonic plates as they shift and interact with one another. Earthquakes are measured on the Richter scale, which is used to determine their magnitude and potential for causing damage. The frequency and intensity of earthquakes can vary depending on location, with some areas experiencing more frequent or severe earthquakes than others.

Morning commuter traffic in cities contributes to ____ smog. In this type of air pollution, a mixing of ____ from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
Answer:
photochemical
hydrocarbon
Explanation:
Morning commuter traffic in cities contributes to photochemical smog. In this type of air pollution, a mixing of hydrocarbons from certain plants, nitrogen oxides from cars, and UV radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.
Photochemical smogs are caused by the photochemical reaction of hydrocarbon and nitrogen oxides in the lower atmosphere with sunlight playing a major role. The reaction of the hydrocarbon with the nitrogen oxide in the presence of light leads to the evolution of ozone gas while nitrogen oxide has the capacity to react with the sunlight on its own to produce nitrogen dioxide. This result in the formation of smog

Explain how bacteria can be genetically engineered to produce a human protein.
Answer:
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. ... There, the recombinant bacteria use the gene to begin producing human insulin.
Explanation:
Hopefully this helped!
Genetic engineering involves modifying the genetic material of an organism, such as bacteria, to introduce new characteristics or functions. One application of genetic engineering is to use bacteria to produce human proteins, which can be used for various medical purposes such as in vaccines or as therapeutic agents.
What is the first step for the process ?Isolate the gene for the human protein: The first step in genetically engineering bacteria to produce a human protein is to identify and isolate the gene that codes for the protein. This can be done using various techniques, such as polymerase chain reaction (PCR) or DNA sequencing.
Insert the gene into a bacterial vector: Once the gene for the human protein has been isolated, it is inserted into a bacterial vector, which is a small circular piece of DNA that can replicate independently within the bacterium. The vector is usually a plasmid, which is a type of DNA that can be easily manipulated and introduced into bacterial cells.
Introduce the vector into bacteria: The next step is to introduce the vector carrying the human gene into the bacteria. This can be done using various techniques such as electroporation, heat shock, or transformation.
Allow the bacteria to produce the protein: Once the vector carrying the human gene is inside the bacterial cell, the cell can begin to produce the human protein. The bacterial machinery reads the genetic code in the gene and synthesizes the protein.
Extract and purify the protein: After the bacteria have produced the protein, it can be extracted and purified. This involves breaking open the bacterial cells to release the protein, and then using various purification techniques to isolate and purify the protein.
Test the protein for activity and safety: Finally, the purified protein is tested to ensure that it is active and safe for use in humans. This can involve various assays and tests to confirm the protein's function and purity.
In summary, genetic engineering can be used to introduce the gene for a human protein into bacteria, allowing the bacteria to produce the protein, which can then be extracted, purified, and tested for medical use. This process can be used to produce a wide variety of human proteins, including hormones, enzymes, and antibodies.

organisms?
♡
Answer:
its either meiosis or mitosis i cannot remember which though
Explanation:
The process that is important in increasing genetic diversity in organisms is meiosis, and in this process, the genetic diversity is seen due to the genetic crossing over and the recombination.
What makes meiosis important for the organism?Meiosis is the process in which the parent cell makes the gametes that are haploid in nature; the male makes the sperm and the female makes the ovum in this process, and each of these gametes contains half of the genetic materials of the parent. Because meiosis results in genetic diversity in nature, it is important for the organism that produces offspring through sexual reproduction, and genetic diversity is seen in animals due to this process.
As a result, meiosis is an important process for increasing genetic diversity in organisms, and genetic diversity is visible during this process.
