Answer:
2 decomposer or 3 producer
Explanation:i kinda forgot lol
Option 2. Decomposers are the organisms that can obtain energy from any other organisms in an ecosystem as they breakdowns all type of dead organisms.
In an ecosystem, there are various kinds of organisms on the basis of their feeding behavior such as:
Producers: make their food and energy on their own.Herbivore - a primary consumer that depends upon producers for its energy and food. Carnivore - a secondary consumer that depends on herbivores or other consumers.Decomposers: organisms that get their energy and nutrition from any organism are dead or organic matters such as animal and plant wastes.Thus, the correct answer is - 2) decomposers.

It is known that some tumors are associated with tumor viruses. It remains unknown, however, whether or not other tumors such as those induced by chemical carcinogens are also associated with tumor viruses. Design a series of experiments to test the hypothesis that a chemical carcinogen-induced tumor cells contain altered genome (as compared to its unaltered state in the normal cell counterparts) and this genomic DNA alteration is responsible for the transformed phenotypes of the tumor cells. Include in your experimental design the following:
1) the overall strategy,
2) the reagents chosen including controls and why they are chosen,
3) at least four types of transformation assays, including both in vitro and in vivo assays, to be used to measure the properties of transformed cells, and
4) the strategy to interpret the results and to draw a conclusion.
Answers
Answer:
Experimental procedure:
1- To expose cell lines to both chemical carcinogens and viruses known to produce cancer (e.g., Epstein-Barr virus, hepatitis B virus, human papillomavirus, herpesvirus-8, etc) simultaneously.
2- By using real-time PCR (RT-PCR), to amplify mRNAs for specific target oncogenes both in normal cells and in cells that acquired cancer traits such as, for example, cell proliferation and survival. During this experimental procedure, it is required to include in vitro transformational assays including 1-anchorage independence, 2-morphological transformation (where the cells are scored for lack of contact inhibition), 3-focus formation and 4-immortalization.
3- Also by RT-PCR, to amplify mRNAs for specific viral mRNAs (i.e., to determine the viral load) in cancer-related cell lines.
4- To determine if there is a statistical significance between specific oncogene mRNAs versus viral expression in cancer-related cell lines
Experimental controls:
- Negative control: normal cells (i.e., cells non-exposed to chemical carcinogens and viruses)
- Positive control: immortalized cell lines where it has been found that the target oncogenes are expressed. It is possible to obtain this genetic data from other studies (i.e., by searching this information in the corresponding scientific publications)
Explanation:
By using this experimental procedure, it is possible to identify if there exists a correlation between the presence of viral mRNA and oncogenes previously recognized for being amplified in different types of cancers in cell lines that were capable of developing cancer traits.

Briefly explain what properties of the atoms in water (H2O) give water the ability to form hydrogen bonds. Your answer should include the words: electronegativity, hydrogen, oxygen, electrons, protons.
Answers
Answer:
Water molecules are polar, so they outline hydrogen bonds. This gives water great properties, such as a for the most part high bubbling or boiling point, tall specific warm, cohesion, grasp, and thickness. Hydrogen has an electronegativity of 2.0, though oxygen has an electronegativity of 3.5. The refinement in electronegativities is 1.5, which infers that water can be a polar covalent molecule. In water, an electron from each of the hydrogen particles is drawn towards the oxygen particle. Protons, as unequivocally charged hydrogen particles, move outstandingly rapidly in water from one water molecule to the taking after, which is why the conductivity of water is modestly tall.

How do the potential energy and the kinetic energy change when the skateboarder is at the top or the bottom of the hill? Why do you think this change occurs?
Answers
Answer:
Potential at the top. Kinetic when going down the hill.
Explanation:
Its basically mechanical energy! While at the top you have the potential to go down and race down using kinetic energy.
Answer:
The potential energy (P.E) and the kinetic energy (K.E) are two types of distinct energy that is commonly observed in our day-today's life.
Usually, K.E is defined as a type of energy that is produced when an object is in motion. Where, as P.E is a type of energy that is stored in an object when that object is placed at a certain height.
In the given condition, when the skateboarder is at the top of the hill, then at that position, it is comprised of maximum P.E. As the he slowly comes down the hill, then the P.E gradually decreases, and the K.E gradually increases. This shows the P.E is slowly changing into the K.E. And as it comes down, the K.E increases, and eventually when he stops, then both the K.E and P.E becomes zero.
This changes occurs because energy can never be created nor destroyed, and it changes from one form to another.

What is Pacific trade?The focus of American policy was the Trans-Pacific Partnership (TPP). a geopolitical shift by President Barack Obama toward Asia.
The TPP was slated to become the greatest free trade agreement in history, encompassing 40% of the world economy, but President Donald Trump withdrew the United States in 2017.
According to those who supported it, a deal of this nature would have increased American investment and trade abroad, boosted economic growth, reduced consumer prices, and produced new employment, all while furthering American strategic objectives in the Asia-Pacific area.

what is temperature ?Temperature can be defined as the hotness or coldness sensation of the body, determining the kinetic energy of particles in an object, the temperature increases as the movement of the particle go in a Faster rate.
The temperature has the role in every area and in all scientific disciplines, it is measured with the instrument like thermometer or a calorimeter, it determines the internal energy in a given system.
For the determination of temperature a sensor is used called RTD or Resistance Temperature Detector or a thermocouple which collects the temperature data from a particular source and converts these data into an understandable data.

What structure is found in viruses but not in cells?
Answers
Answer:F
Explanation:
One structure that is found in viruses but not in cells is the viral capsid.
What is a virus?Viruses are infectious agents that are much smaller and simpler in structure than cells. While cells are complex structures that have many components, including a cell membrane, cytosol, and organelles such as the nucleus and mitochondria, viruses have a much simpler structure.
One structure that is found in viruses but not in cells is the viral capsid. The capsid is a protein shell that surrounds and protects the viral genome (DNA or RNA). The capsid is made up of proteins called capsomeres, which are arranged in a specific pattern to form a shell around the viral genome. The capsid helps the virus to infect host cells and replicate its genome.
Viruses may also have a viral envelope, which is a thin layer of lipids that surrounds the capsid. The envelope helps the virus to enter host cells and may also contain proteins that allow the virus to evade the host's immune system.

B, the cell membrane
Explanation:
The cell membrane dictates what enters and exits the cell. It keeps the important stuff (such as organelles) inside the cell, allows nutrients to enter the cell, and keeps unwanted ¨things¨ from entering. The tea bag does roughly the same thing.
It keeps the important contents inside (in this case the tea leaves), allows water to come inside, and keeps whatever is in the water outside of the teabag. Obviously the cell membrane is much more complicated than a tea bag, but the tea bag works as a nice analogy.
