Group of answer choices
interference
refraction
reflection
diffraction
Answers
The bending of waves around a barrier or through a slit is called ( D ) ; Diffraction
Diffraction is the term used to describe the situation/phenomena whereby waves ( radio or cell signals ) emanating from an antenna is bent around obstacles between the antenna and the signal receiver.
Diffraction of waves is usually caused by the interference of waves with itself due to the presence of an obstacle. in order to get to the intended receiver the waves bends around the barrier through diffraction after constructive interference within itself.
Hence we can conclude that the bending of waves around a barrier or through a slit is known as diffraction

DNA is genetic material that makes up living things and folic acid
Answers
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.

Due to the presence of mineral salt in the osteoid matrix, which is a crystalline complex of calcium and phosphate (hydroxyapatite). Calcified bone contains about 25% organic matrix (2-5% of which are cells), 5% water and 70% inorganic mineral (hydroxyapatite).
Explanation:
I think you answered on of my questions before or was on one of mine lol.
I am not sure but I recognize the pfp
The appearance of mineral salt in the osteoid matrix, which would be a crystalline complex of calcium and phosphate, contributes to bone hardness and rigidity.
What are osteoid matrix?The osteoid is the unmineralized, organic portion of the bone matrix that constructs prior to bone tissue maturation.
It usually initiate the formation of bone tissue by secreting the osteoid as a series of specific proteins.

O Students communicate results through secondary sources, and professional scientists communicate results through
primary sources.
Answers
The correct answer is C. Students communicate results in laboratory reports, and professional scientists communicate results in scientific journals.
Explanation:
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.

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.

What are two ways that you could change the path of light? what materials would you need to do it?
Answers
Answer:
Light travels in a straight line until something alters its path. Here are three ways light's path can be altered: it can be refracted, reflected, or absorbed.
Materials such as a mirror or aluminum can reflect light.
Materials such as water or glass can refract light.
Materials such as coal or clack paint can absorb light.
The two different ways that a person could change the path of light are refraction and reflection of light.
What is Refraction and reflection?Reflection is the phenomena of bouncing back of the light rays when it strikes the medium such as air, water, etc on a plane. Refraction can be defined as the process of the deflection of light when it passes through a medium that lead to the bending of light rays.
The two main ways in which the light's path can be altered include refraction and reflection of light.
For example, materials such as a mirror or aluminum can reflect light, materials such as water or glass can refract light.
