Answer:
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.

Which type of organism can obtain energy
directly from any of the other organisms in an
ecosystem?
(1) herbivore
(3) producer
(2) decomposer (4) carnivore
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.

Both students and scientists can carry out scientific research that involves studying a phenomenon by using the scientific method and scientific instruments. However, professional scientists and students differ in their level of knowledge and expertise in science. This makes scientific research made by scientists to have some differences in comparison to scientific research by students.
One of these differences is the way results are communicated. Indeed, students develop simple scientific research and the results are communicated in laboratory reports at school, colleges, etc. On the other hand, professional scientists develop complex research. Due to this, results are communicated in academic texts with strict criteria and that can be seen by other scientists, these are known as scientific journals.
How do each growing stage of an insect vary?
Answer:
Most insects change in form during their development, and the successive stages are not all alike. This change in form is called metamorphosis. It is controlled by a juvenile hormone secreted by glands in the insect's head. The juvenile hormone is released during each molt, but the amount decreases each time.

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.
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.
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?
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.

DNA is genetic material that makes up living things and folic acid
Answer:
The correct answer is option (C) The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.
DNA or the deoxyribonucleic acid is made up of the nitrogenous bases called the purines and pyrimidines. Folic acid or the vitamin B9 is essential for the synthesis of these nitrogen bases of the DNA. A scientific experiment conducted always has two parameters, a dependent and a independent variable. A dependent variable in an experiment is a variable which is being tested and measured. In the experiment Jon is conducting, the amount of DNA becomes an dependent variable which is being tested and measured in presence of folic acid. An independent variable in an experiment is the variable that is changed or controlled in the scientific experiment to test the effects on the dependent variable. Here, folic acid becomes an independent variable as the amount of it is varied and tested to check the formation on DNA in bacteria. Thus, an independent variable always changes to check its effect on the dependent variable.
