Answer: 69kg
Explanation:
Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:
55% of x = 38kg
55/100 × x = 38kg
0.55 × x = 38kg
0.55x = 38kg
Divide through by 0.55
x = 38kg/0.55
x = 69.09099
x = 69kg
Therefore, the woman's total weight is 69kg.

When it was time to go outdoors, 3-year-old Casandra said she didn’t want to play and headed for her locker. At the teacher’s gentle insistence, Casandra reluctantly joined the other children on the playground. Tears rolled down her cheeks when the teacher boosted Casandra onto a swing seat and began to push her. The teacher stopped the swing and helped Casandra off. She held her closely for a few minutes and then asked why she was crying. Casandra initially denied that anything was wrong. However, when the teacher persisted, said she "had fallen the night before and hurt her bottom."
The teacher took Casandra inside and asked to see where she had been hurt. When Casandra pulled down her shorts, the teacher noted what appeared to be a large burn with blisters approximately 2 inches in length by 1 inch in width on her left buttock. Several small bruises were also evident along one side of the burn. Again, the teacher quietly asked Casandra how she had been hurt, and once again she replied that she "had fallen."
What actions should Casandra’s teacher take?
Answer:
casandra was scared around others
Explanation:
in the passage i notesed that she went to her locker and started crying
Answer: 1. Casandra's teacher should take her to the nurse and just tell the nurse that she got hurt in the playground 2. The teacher should gather more evidence until she knows that something is going on because she can't prove that something is really happening 3. She shouldn't tell the parent yet because they would probably accuse the teacher of doing it 4. If it was the first time , I would feel bad for the girl and just tell her to be careful but if it kept happening, I would tell the principal and her parents and I would feel angry

describe the three general methods used by ecologists to study organisms
Answer: The three main research methods used are observation, modeling, and experimentation.
Explanation:
Observation:
Every experiment requires observation. Ecologists must observe the environment, the species within it, and how those species interact, grow and change. Different research projects different types of assessments and observations.
Ecologists sometimes use a desk-based assessment, or DBA, to collect and summarize information about specific areas of interest. In this scenario, ecologists are using information already collected from other sources.
Oftentimes, however, ecologists rely on observation and fieldwork. This entails going into the habitat of the subject of interest to observe it in its natural state. By doing field surveys, ecologists can track the population growth of species, observe community ecology in action and study the impact of any new species or other introduced phenomena in the environment.
Each field site will differ in nature, shape, or other ways. Ecological methods allow for such differences so that different tools can be used for observations and sampling. It is crucial that sampling be done randomly to combat bias.
Modeling:
Ecological methods rely heavily on statistical and mathematical models. These provide ecologists with a way to predict how an ecosystem will change over time and react to changing conditions in a system.
Modeling also provides another way to decipher ecological information when fieldwork is not practical. There are several drawbacks to relying solely on fieldwork. Because of the typically large scale of fieldwork, it is not possible to replicate experiments exactly. Sometimes even the lifespan of organisms is a rate-limiting factor for fieldwork. Other challenges include time, labor, and space.
Modeling provides a method in which to streamline information more efficiently.
Examples of modeling include equations, simulations, graphs, and statistical analyses. Ecologists use modeling for producing helpful maps as well. Modeling allows for calculations of data to fill in gaps from sampling. Without modeling, ecologists would be hampered by the sheer amount of data that needs to be analyzed and communicated. Computer modeling allows for comparatively rapid analysis of data.
A simulation model, for example, enables the description of systems that would otherwise be extremely difficult and too complex for traditional calculus. Modeling allows scientists to study coexistence, population dynamics, and many other aspects of ecology. Modeling can help predict patterns for crucial planning purposes, such as for climate change.
Humanity’s impact on the environment will continue. It, therefore, becomes ever more crucial for ecologists to use ecological research methods to find ways to mitigate the effects on the environment.
Experimentation:
The overarching purpose of ecological methods for research is to get high-quality data. Experiments must be carefully planned.
Hypothesis: The first step in any experimental design is to come up with a hypothesis or scientific question. Then, researchers can come up with a detailed plan.
Factors that affect fieldwork experiments include the size and shape of an area that needs to be sampled. Field site sizes range from small to very large, depending on what ecological communities are being studied. Experiments in animal ecology must take into account the potential movement and size of animals.
For example, spiders would not require a large field site for study. The same would be true when studying soil chemistry or soil invertebrates. You could use a size of 15 meters by 15 meters.
Herbaceous plants and small mammals might require field sites of up to 30 square meters. Trees and birds might need a couple of hectares. If you are studying large, mobile animals, such as deer or bears, this could mean needing a quite large area of several hectares.
Deciding upon the number of sites is also crucial. Some field studies might require only one site. But if two or more habitats are included in the study, two or more field sites are necessary.
Tools: Tools used for field sites include transects, sampling plots, plotless sampling, the point method, the transect-intercept method, and the point-quarter method. The goal is to get unbiased samples of a high-enough quantity that statistical analyses will be sounder. Recording information on field data sheets aids in the data collection.
A well-designed ecological experiment will have a clear statement of purpose or question. Researchers should take extraordinary care to remove bias by providing both replication and randomization. Knowledge of the species being studied as well as the organisms within them is paramount.
Results: Upon completion, collected ecological data should be analyzed with a computer. There are three types of ecological experiments that can be made: manipulative, natural, and observational.
Hope This Helps!
The 3 general methods used by ecologists to study organisms include:
ObservationModellingExperimentationObservation involves observing organisms in their natural habitats or environments and then recording the findings. It is usually done by field surveying.
The different species living in an environment, how they interact with each other and other abiotic components of the environment are some of the observations taking during field surveys. The growth of individual species, the effects of introducing new species, their adaptations and other areas of community or ecosystem ecology can be studied through observation.
Modelling requires a simulation of real-life ecological processes through different manipulations. This could be done in the laboratory, on the field, or even on the computer. Computer modelling requires that data from observation or experimentation are supplied as input and the inputs are subject to mathematical maneuvering.
With models, complex ecological processes can be simulated and analyzed and extrapolated to deduce how things might happen in real life ecological interactions.
Experimentation involves setting up experiments following the scientific method. It can be a observational or controlled experiments.
Observational experiments requires studying organisms, populations, communities, or ecosystems through pure observation without changing or manipulating any variable.
Controlled experiments requires that variables are introduced and manipulated in some groups while some groups serve as the baseline without any manipulated variables.
Data are obtained from experiments and these are analyzed in relevant ways to support or reject hypotheses.

Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
b. False
Answer:
Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.
a. True
Explanation:
A woman's estrogen levels become highest towards the end of her ovulation. At this point, the woman is naturally prepared for a possible pregnancy. The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women. By the end of the luteal phase, the corpus luteum function declines.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.
