Ms. LePoint described three steps to achieving success. Describe those steps. 3. Explain the term mathaphobia, then explain how that term might apply to you as a STEM student. Also, does it only apply to math? 4. In the video, Ms. LePoint described how she transitioned from a failing student to one who eventually became a rocket scientist. Why was her mindset so important to her success? How did her mindset change?
Answers
Yes, many of these obstacles are specifically related to her sex, race, and gender.
In the video, some of the obstacles Ms LePoint faced included being part of a family of farmers in a small town, lack of financial resources, lack of role models, and not believing that she could pursue a career in STEM.
The three steps Ms. LePoint mentioned for achieving success are:
Perseverance: don't give up even when faced with obstacles,
Mentorship: find people who can support and guide you, and
Resilience: have a strong sense of self and don't allow others to put you down.
Mathaphobia is a fear of mathematics, often stemming from negative past experiences with math. As a STEM student, mathaphobia might prevent you from pursuing higher math-related studies or even enrolling in classes. However, it is not limited to math, as other types of phobias, such as writingaphobia or codephobia, may also affect students.
Ms. LePoint's mindset was extremely important to her success because it allowed her to continue striving despite the odds being against her. She was able to make the transition from a failing student to a rocket scientist by developing a growth mindset, which involves viewing obstacles as opportunities to learn, and cultivating a sense of resilience and self-belief.

PLEASE HELP GIVING BRAINLEIST
The scientific method is a process that many scientists use to prove or disprove natural phenomena. It starts with scientific inquiry or questions that arise from an observation. For this project, observe your natural environment, and come up with a question that you would like to test using the scientific method. Remember, the scientific method is limited or restricted to investigating those physical phenomena that are:
observable;
measurable;
repeatable;
falsifiable.
You don't actually have to conduct the experiment, but you will have to explain the steps of how you would set it up and conduct it. Here is a summary of the steps of the scientific method that you must address:
Define the problem. Look around your house or outside. Is there anything that you're wondering about or have questions about? For instance, do you have any animals in the home? Maybe you have a hamster and wonder if it is more active in the day or at night. If you go outside, look at birds or insects. Maybe you wonder if ants have a food preference. Your question doesn't have to involve live organisms. Maybe you wonder what type of material best blocks out the Sun or if your sense of sight or smell affects how food tastes. Think of a question you want answered and state it in the first box below.
Research the problem. Get on the Internet or go to your local library and conduct some research on your topic. For example, what does the research say about the activity of a hamster or the food preference of ants? Or what does the research say about materials that are used to block out the sun. Or what are the effects of sight or smell on our taste buds? For whatever problem you proposed, find some information on it to help you make an educated guess or hypothesis.
Construct a hypothesis. Formulate your hypothesis based on your research. What do you think the answer to your question is? State your hypothesis in an "if-then" format. For example, your hypothesis could be "If my hamster is placed in the maze in the morning, then it will finish the maze quicker than at it would finish it at night." State your hypothesis statement in the second box below.
Design and conduct an experiment. Describe how you will set up your experiment and test your hypothesis in the third box below. You should state the materials that you will need and the measurements that you will make. Keep in mind the control group and experimental group, or any controlled or independent variables, if they apply.
Collect data. How will you set-up your data spreadsheet? What type of data will you record? Maybe you will record the amount of time the hamster takes to complete the maze in the morning versus at night. You may want to repeat the experiment to verify results. Include your data collection method in the third box below.
Draw conclusions. After reviewing your data, what are your results? Was your hypothesis correct or incorrect? If you did not actually conduct the experiment, describe the hypothetical results and the conclusion that can be drawn from those results. If your conclusion doesn't support your hypothesis, how would you change your hypothesis or experiment in the future? Discuss your conclusion in the fourth box below.
Answers
There are a lot of ways that experiment is been done. The steps of how I would set it up my chosen experiment as well as the way to conduct the experiment is given below.
What is the experimental steps?Define the problem: Do different types of music affect the rate at which a plant grows?
Research the problem: After researching, it is found that some studies have shown that plants exposed to classical music have a higher rate of growth compared to plants exposed to other types of music or no music at all. However, other studies have shown no significant difference in plant growth based on the type of music being played.
Construct a hypothesis: If a plant is exposed to classical music, then it will have a higher rate of growth compared to a plant that is exposed to no music or a different type of music.
Design and conduct an experiment: To test this hypothesis, two plants of the same species and age will be used. One plant will be placed in a room where classical music is played for 12 hours a day, while the other plant will be placed in a room with no music. Both plants will be given the same amount of water and sunlight and the rate of growth will be measured over a period of one month. A ruler will be used to measure the height of the plants at the beginning and end of the experiment, and the increase in height will be calculated.
Collect data: Data will be collected by measuring the height of the plants at the beginning and end of the experiment and recording the increase in height in a spreadsheet. The measurements will be taken at the same time each day to ensure consistency.
Draw conclusions: After analyzing the data, it can be determined if the hypothesis was supported or not. If the plant exposed to classical music showed a significantly higher rate of growth compared to the plant with no music, the hypothesis would be supported. If there was no significant difference in the rate of growth between the two plants, the hypothesis would not be supported. If the hypothesis is not supported, a new hypothesis could be formulated and the experiment could be modified and repeated in order to further test the effect of music on plant growth.

What would require more land to grow food crops? If all humans ate only vegetables
or ate only meat. Explain.
Answers
Answer:
If all humans ate only meat, will require more land to grow food crops
Explanation:
1) Currently, over 60% of the world food crops are eaten by animals. Given that food crops are generally consumed more than meat in a proportion of 8:1, if all humans ate only meat, the amount of land required to grow food crops will have to be increased by at least 400%
2) Presently, animal agriculture makes use of 70% of lands allocated to agriculture, such that increasing the livestock by an extra 400% will lead to mass deforestation in order to produce livestock feeds
3) It is more costlier to produce livestock than to produce crops, which will make the availability and allocation of land essential for the raising of livestock in order to reduce costs, thereby taking more land.

How would you draw a DNA molecule that is 10 nucleotides in size?
Answers
Answer:
Explanation:
Adenine an Guanine are purines while cytosine and thymine are pyrimidines.
According to Chargaff's rule, the ratio of purines to pyrimidines is equal.
Thus, the number of cytosine (C) will be equal to the number of guanine (G).
As it is given that the number of guanine-containing nucleotides = 410
Thus, G = C = 410
Now, G + C = 410 + 410 = 820
The number of adenine (A) will be equal to the number of thymine (T).
Thus, A + T = Total number of nucleotides – Nucleotides containing G and C nitrogenous bases
= 1500 – 820 = 680
Therefore, A = 340 and T = 340
The number of adenine will be equal to number of thymine, which is 340.
Therefore, Number of pyrimidines that the segment possess = C + T
= 410 + 340 = 750
6. a 19mm zone of inhibition of is considered as sensitive for cefazolin, but resistant to penicillin. why do different antibiotics have different measurement standards?
Answers
Different antibiotics like cefazolin and penicillin have different measurement standards because they have different chemical structures and mechanisms of action.
The zone of inhibition is a measure of the effectiveness of an antibiotic against a particular bacterium. It represents the area around a disc containing a known concentration of the antibiotic where the bacterium is unable to grow. The size of the zone of inhibition is affected by several factors, including the concentration of the antibiotics, the diffusion rate of the antibiotic through the agar, and the susceptibility of the bacterium to the antibiotic.
Each antibiotic has its specific standard for determining its effectiveness against a particular bacterium. For example, cefazolin and penicillin have different standards because they are different types of antibiotics that work in different ways. Cefazolin is a cephalosporin antibiotic, while penicillin is a penicillin antibiotic.
Therefore, the size of the zone of inhibition for cefazolin may be different than that of penicillin due to differences in their mechanisms of action and their potency against the particular bacterium being tested.
