Answers
Answer:
The procedure is present below.
Explanation:
Take four pots having mint plant with same sizes and then apply 2% salt to pot no.1, then apply 5% salt to pot no.2, apply 10% salt to pot no.3, and apply 15% salt to pot no.4. After a 1 week or 2, see the growth of the mint plants. You will notice some mint plants are not effected to salt concentration because they are present in low quantity whereas some plants experience stunted growth due to higher concentration of salt which is unbearable for the mint plant.
Which of the following characteristics is shared by an ash tree, a cat, yeast, and an amoeba?
a) They break down glucose during the production of ATP.
b) They develop a cell plate during mitosis.
c) They have chitin in their cell walls.
d) They have 19 pairs of chromosomes in each cell.
Answers
Answer:
a) They break down glucose during the production of ATP.
Explanation:
This question is making a comparison of the life processes of the following organisms: ash tree (plant), cat (animal), yeast (fungus), amoeba (protist). As observed, these four organisms belong to four different kingdoms, hence, will have distinct features/characteristics.
For example,
- Only plants like the ash tree develop a cell plate when it is about to divide into two during the process of mitosis.
- Only members of the fungi kingdom contains CHITIN in their cell wall
- Different species of organisms contains its own unique number of chromosome in its cell. Hence, different species cannot all have 19 pairs of chromosomes in their respective cells.
However, all cells of living organisms undergo the process of cellular respiration, which they use to obtain energy (ATP) by breaking down glucose (from their food).

A hot horseshoe transfers heat to the tongs
Radiation
Conduction
Convection
Answers
Answer:
Radiation is the answer
Explanation:
A hot horseshoe transfers heat to the tongs is the example of Conduction. So, the correct option is B.
What is Conduction?Conduction is defined as the process by which heat energy is transmitted through collisions between neighboring atoms or molecules which occurs more easily in solids and liquids, where the particles are closer together than in gases. where the particles are further separated.
Some examples of heat conduction are accidentally touching a hot pot, or when a heating pad is applied directly to and heats a muscle or when a hot horseshoe transfers heat to tongs.
During the conduction of electricity, movement of electrically charged particles occur in the medium. The electric current is carried and moved by the ions or electrons.
Thus, a hot horseshoe transfers heat to the tongs is the example of Conduction. So, the correct option is B.

4. Do you think that increasing the number and kinds of observations you make about something would affect any inferences you make about those observations? Why or why not?
Answers
Answer: The number of observations (sample size) is important in determining the reliability of statistical inferences. The kind of observations depends on what hypothesis is being tested. Different statistical techniques are required depending on whether the data is categorical or discrete or continuous and whether observations are quantitative or qualitative. Increasing the kinds of observations (multiple sets of data) may also add to the reliability of the test of the hypothesis.
Explanation:
In general, a larger sample size improves the reliability of any statistical inference, particularly when there is more variability (higher variance) in the data and when the expected effect is small. A larger sample reduces the chance of random error.
Where more than one variable is associated with output data, it is of course necessary to collect data of different kinds. For example, if your hypothesis is:
H: y = ax1 + bx2 + cx3 + ...........
then you need to have observations of x1, x2, x3.........

A particular protein has the amino acid sequence: . . . Ala-Pro-His-Trp-Arg-Lys-Gly-Val-Thr . . within its primary structure. A geneticist studying mutations affecting this protein discovered a mutant that produced a shortened protein molecule that terminated within this region. In this mutant protein, the His became the last amino acid. What DNA single-base change(s) would cause the protein to terminate at the His residue
Answers
Answer:
The correct answer is - nonsense mutation.
Explanation:
The given amino acid sequence Ala-Pro-His-Trp-Arg-Lys-Gly-Val-Thr of a particular protein is affected by a mutation that leads to the shortened protein that ends in this region only. As we know the His amino acid becomes the last amino acid so in such case is it takes place due to nonsense mutation that is the only mutation or change result to terminate before or at the His codon.
The Trp codon which is coded by UGG codon could have been changed to either a UAG or a UGA codon in this case.
The correct answer is - nonsense mutation.
science for environment health peace and equity
Answers
Environment:
Science helps the environment because it creates an understanding between human impacts and the environment. By gaining this understanding of how the natural world works, the human race will better know how to protect it. In addition, scientific research is being used to reduce the impact of global warming, adapt to climate change, clean up polluted areas, and protect our own health.
Health:
Science can be used to improve global health because it fuels discovery, informs the public on health risks and programs, and helps all people live healthier and better lives. People with physical and mental health can benefit greatly from a variety of health sciences that specialize in their specific ailment. There have also been improvements in the technology used in health such as sanitation, vaccinations, and monitoring systems. By enabling doctors to do minimally invasive surgeries and using more comfortable scanning equipment, patients spend less time recuperating and can spend more time doing what they enjoy.
Peace:
It is my opinion that communication is the main way that science influences peace. Scientists from all over the world collaborate in an unbiased way to focus on one main goal, to deliver scientific breakthroughs to people regardless of religion, race and culture. Furthermore, science contributes to the social and economic development in a society (such as GDP, life expectancy, and literacy), reduction of poverty (through new was to meet basic needs for food, clothing, and shelter), and inspires a newfound peace mindset.
Equity:
Peace is a strong piece of science and, therefore, equity. Science is heavily rooted in the creation of new knowledge, the improvement of education, and the improvement of the quality of human life regardless of bias. Because of this, science can be used to research and find ways to solve pressing issues like racial and economic inequity. Learning of science in schools also has an impact on equity by teaching children the basis of our world and how to understand in order to gain skills that lead to better economic and social outcomes.
Science is playing a vital role in maintaining the environment, health, peace, and equity. But the way is different for each of the parameters.
What is Science?Science is the cognitive and practical activity that encircle the methodological study of the structure and behavior of the physical and natural world through observation and experiments.
Science changed the overall structure of the environment. It creates an interaction between humans and the environment. Scientific researches are to be performed on yearly basis on how to reduce the impact of deforestation, global warming, ozone depletion, and increase biodiversity at the global level.
Health is a term that is synergistically related to science. Science very vastly covers the area of health and sanitation. For example vaccine development, drug therapy, immune-boosting, etc. Apart from this science significantly develops new technology and equipment that gives the idea of the health of any individual in a very less time.
Peace is maintained by science in such a way that scientists from all over the world work together to fight against particular concerns. And also how to improve the facilities for health, environment, technology worldwide.
Science also somehow manages equity at the world level by providing good education, a better understanding of technology, fighting against poverty, etc. Learning of science in educational institutes improves the understanding as well as promotes skills to the people.
Therefore, in this way, Science is playing a vital role in maintaining the environment, health, peace, and equity.
