Answer:
What would be accepted by coworkers.
Accepted by coworkers is the correct option.
Explanation:
The young woman's refusal to "tell others" about the deal triggers a question about what would be accepted by coworkers because her actions will determine what others will think about the issue, their ideaologies and what actions they might take.
If her refusal to tell others about the deal does not in one way or the other affect other Co workers negatively, the coworkers might accept it in a negative way and if it's affect them positively,they might accept it positively. The co-workers acceptance about the whole issues will be what they feel and their decision is and this can trigger actions.
The young woman's refusal to "tell others" about the deal triggers a question about what would be: Socially responsible.
Who is a Socially Responsible Person?A socially responsible person is one that has a duty to act in the best interests of the organization or community that he represents. In organizations, confidentiality is often valued.
So, the fact that the young woman did not tell others about the deal shows that she is socially responsible.

how come human populations differ from other animal populations
Answer:
Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals ...
Explanation:
With in population, humans show low levels body height variation in comparison to variation observed in other animal population.
Similarly, human population does not show distinctive levels of body mass variation.
What are the importance of studying human population?The study of population helps us to understand the process that influence the size, growth, characteristics, and distribution.
Population studies highlight these problems for society, administrators, political System, economic Planning
The most important terminology which is immensely studied called demography where the study of human population is extremely essential to determine the age, composition.
It is essential to study in every country by analyzing patterns of life expectancy and accurately predict the future.
Demography is important to study, as it characterize the nature population changes over time, such as the aging population
Hence, humans population show low levels body height variation in comparison to variation observed in other animal population.

Answer:
No - they do not contain nitrogen which is needed to make proteins and nucleic acids (sometimes lipids)
Explanation:
The four types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Sugars are carbohydrates, and contain carbon, hydrogen, and oxygen.
Lipids contain carbon, hydrogen, and oxygen, and sometimes other elements like nitrogen and phodphorus.
Proteins contain carbon, hydrogen, oxygen and nitrogen.
Nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and phosphorous

What factors challenge the stability of an organism?i
Answer:
Abiotic factors.
Explanation:
Abiotic factors such as temperature and humidity etc challenge the stability of an organism by providing the harsh environment. This harsh environment disturbs the stability of the organism. Increase in temperature and very less or high humidity imbalance the enzyme activity which disturbs the whole functioning of the body of organism. So for chemical processes in the body, suitable temperature is required.
Cells contain specialized structures called organelles that have specific functions that enable the cell to carry out life
processes. Organelles work together to perform all the functions of the cell. Which of the choices is the BEST example of
how the cell membrane and chloroplast might work together to make food in a particular cell?
A In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast uses nutrients to make energy (ATP)
for the cell.
B. In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
C. In animal cells, the cell membrane allows materials in and out of the cell, while the chloroplast uses nutrients to make energy (ATP)
for the cell.
Din animal cells, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
Answer:
B. In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by
photosynthesis.
Explanation:
The choice that represents the best example of how the cell membrane and chloroplast might work together to make food in a particular cell is as follows:
In a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by photosynthesis.Thus, the correct option for this question is B.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates the internal environment of the cell with respect to its outer one. It is semi-permeable in nature. It means that some molecules, ions, or compounds can easily diffuse across the lipid bilayer while others are not.
The movement of materials in and out of the cell is typically facilitated by the cell membrane. While in plants, the chloroplast is a membrane-bound cell organelle that has green pigments that captures light energy from sunlight and convert it into chemical energy in order to synthesize food (glucose) that provides them energy for metabolic activities.
Therefore, in a plant cell, the cell membrane allows materials in and out of the cell, while the chloroplast makes food for the cell by photosynthesis. Thus, the correct option for this question is B.

Answer:
1. 6.7%
hope it helps <3
The percentage deviation in the student's calculation is 6.74%.
We have a student who incorrectly measured the volume of a mineral sample.
We have to determine student's approximate percent deviation.
How to calculate the Percentage deviation ?In order to calculate percent deviation , subtract the true value from the measured value, then divide by the true value, then multiply by 100.
According to the question -
Measured volume (M) = 83 cubic centimeters.
Actual Volume (A) = 89 cubic centimeters.
ΔV or [tex]$\delta[/tex]V = M - A = 83 - 89 = - 6
Therefore -
|Percentage deviation| = [tex]\frac{\delta V}{A} \times 100[/tex] = - ( [tex]\frac{6}{89} \times 100[/tex]) = - 6.74 % = 6.74%
Hence, the percentage deviation in the student's calculation is 6.74%.

hydrophilic?
Answer:
Cell Membranes
Phospholipids are amphiphilic, meaning they are both attracted to water in one region of the molecule, and repel water in other regions. The head of the phospholipid molecule is the hydrophilic region. The tails are the hydrophobic region, and point inward, toward each other.
Explanation:
Answer:
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the diagram below, each phospholipid molecule has a head and two tails. The head “loves” water (hydrophilic) and the tails “fear” water (hydrophobic).
