Answer: 1. Scientific theory
2. Scientific hypothesis
3. Scientific law
Explanation:
The scientific theory can be defined as the aspects of the natural world that are tested and proofed by the scientific methods, involving the observations, measurements and evaluation of the outcome. The scientific theory can be changed with new ideas or evidences. The first statement is a scientific theory because the microbial population may change due to the fact that how microbes interact rather than restricting to the differential reproductive success.
The scientific hypothesis can be defined as the statement that is required to be tested or verified by scientific method. It is based on presumption. The second statement is the example of scientific hypothesis because it is beginning with "if" here it is presumed that if the culture is exposed to ultraviolet radiation then reproductive success rate will be reduced.
The scientific law is based upon facts or evidences obtain after experimental trails or applying the scientific methodology. This cannot be changed with time. The third statement is the Mendel's law of dominance.

Express a
mass of 0.014 mg in grams
Answer:
14 mg
Explanation:
1 g = 10³ mg = 1000 mg
0.014 g * 1000 mg/1g = 14 mg
0.014mg in grams would be equal to 1.4 × 10^-5 gram.
What are unit conversions?There are a few items that we track in our daily activities, including the following:
Speed \sTemperature \sArea \sVolume \sMass
Units of measure are needed in order to measure these values. Sometimes the units of measurement employed may not correspond to the standards required for a particular process or application, as well as the measuring choice and convenience.
It's crucial to convert these units in a way that makes sense and can be used effectively. Let's use the example of someone who is only familiar with the metric system to better grasp the statement.
The person finds it difficult to determine the height of a 25-foot tree. The individual will comprehend the height of the tree better if they convert 25 feet to meters.
Therefore, the conversation of 0.014 mg in grams would be by 0.014/1000 = 1.4 × 10^-5 gram.

A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), RNA and fat. The samples are in test tubes marked 1-5, but the student doesn't know which compound is in which tube. The student is instructed to identify the contents of each tube. Base on these data, identify what is in each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 3. In the next test, she finds that tubes 1, 2, and 3 are positive for nitrogen but only tube 2 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 1 contains a high percentage of phosphate. In the final test the student shows that compound 5 is hydrophobic. Base on these data, identify what is in each tube. 1 2 3 4 5 A. lactose B. RNA C. lysine D. fat
Answer:
1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat
Explanation:
RNA contains both nitrogen and phosphate hence it is the substance in tube 1.
Insulin being a protein contains sulfur hence it is the substance in tube 2.
Lysine does not hydrolyse hence it is the substance in tube 3.
Fat is hydrophobic hence it is the substance in tube 5.
Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.
Based on these data, each tube is identified as:
tube 1: RNAtube 2: Insulintube 3: Lysinetube 4: Lactosetube 5: Fat1. first testHydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.
2. second testNitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.
3. third testIn RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA
5. 4th testFatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.

HIF1α is a key player in angiogenesis. VHL is a protein required for the degradation of HIF1α in the normal oxygen level. Loss-of-function mutations in the VHL gene have been found to promote tumor growth. Please explain why these mutations can promote tumor growth?
Answer:
Explanation:
The VHL gene is a tumour suppressor gene that regulates cell growth and cell death. This gene is also located on chromosome 3. It functions to prevent rapid proliferation of cells. For a person to develop tumor both copies of the gene must be mistake or altered allowing for a loss of function that prevents its from causing degradation of HIF1α in the normal oxygen level as its it normal function. This then allows for the survival of HIF1α that promotes amgiogenesis promoting tumor development.

One function of the poly-A tail on eukaryotic MRNA sequences is to help the MRNA be transported from the nucleus to the cytoplasm. Prokaryotic mRNA also has a poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.
Answer:
In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).

The diagram below shows a magnified view of a cross section of a plant root tip. Four parts of the root and the process that each performs are shown. Which process is directly responsible for root growth in plants?
a. storage
b. absorption
c. transportation
d. cell division
Answer:part c transportation
Explanation:
The process directly responsible for root growth in plants is cell division. So, the correct option is D.
What is Cell division?The process by which a cell divides into two or more daughter cells is called cell division. In relation to the above question, cell division is the mechanism due to which plant roots grow.
The meristematic region, which is in charge of cell division, is designated as part D in a cross-section illustration of the root tip of a plant. The meristem of the root is a unique region where cells continuously divide and differentiate into different tissues, helping the root to expand and mature.
Many tissues of the root, including the epidermis, cortex, and vascular tissue, are composed of distinct types of cells that differentiate when they divide into specialized cell types.
So, the correct option is D.

Why do you think the pace of the development of society is not equal everywhere?
Write in four points.
The correct answer to this open question is the following.
These are the four points that explain the reason why the pace of the development of society is not equal everywhere.
1.- Education. Formal education is of the utmost importance in societies that are considered developed or part of the first world. On the other hand, lack of education is a major reason why people stay ignorant and progress is minimum. Governments must invest in a good public education system with opportunities for all.
2.- Infrastructure. If the country cannot cover the necessities of its citizens, it would be more difficult to develop the kind of infrastructure that allows growth for the nation. This means poor means of communication, poor road conditions, lack of trade systems, poor health services, and limited resources to create jobs in industries.
3.- Culture. People's idiosyncrasy has a lot to do with the way they think and behave. This directly impacts the way people see life, personal progress, ambitions, and aspirations.
4.- Location. Often, geographical location limits the progress and development of a country. For instance, Middle East countries have a problem accessing water resources. Or countries that have geographical features such as mountain ranges or deserts that limit communication and trade with other countries.
The pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.
What is Social Development?Social development is an important factor found in society, capable of changing its social and economic course, so that the increase in social development means an increase in human capital and in social capital itself, moreover, it means more than a quantitative issue. , but also something qualitative.
With this information, we can conclude that pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.
