What are two ways that society affects the progress of science?
Answer:
Technology usually affects society more directly than science because it solves practical problems and serves human needs (and may create new problems and needs). In contrast, science affects society mainly by stimulating and satisfying people's curiosity and occasionally by enlarging or challenging.
Explanation:
What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations
Answer:
Please find the detailed explanation below
Explanation:
A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.
Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.
Why is digestion of fats difficult as compared to that of other nutrients?
This is because fats are insoluble in water and therefore are more difficult to digest than any other nutrients. They also present as large globules.
Hope that helped!!! k
Answer:
Fats take longer time to digest than carbohydrates. Fats can't be digested easily as its insoluble in water and are presented as large globules. The bile juice that gets secreted breaks down the fat from bigger droplets into smaller ones.

Which is the FALSE statement about this blood pressure measurement? 147/92 A. 92 is the diastolic number. B. 147 is the systolic number. C. This is a high blood pressure measurement. D. This is a normal blood pressure measurement.
Answer:
The false statement is - option D.
Explanation:
The lower value is known as diastolic number which is the pressure in the arteries when the heart takes rest in between two consecutive heart beats. Diastolic value shows the pressure of arteries when heart fills with blood.
The upper value or number is known as the systolic number, it is the pressure value of arteries of an individual during the contraction of hear. The normal blood person of a health person is range from 80/60mmhg to 120/90 mmhg, above this range is considered as high blood pressure.
Thus, the false statement is - option D.
If the number of cigarettes smoked increases, then the risk for lung cancer increases. Independent variable: _______ Dependent variable: _______ If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase. Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______
Complete Question:
Part A: Identifying Variables
Read the following hypotheses and identify the variables.
If the number of cigarettes smoked increases, then the risk for lung cancer increases.
Independent variable: _______
Dependent variable: _______
If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.
Independent variable: _______
Dependent variable: _______
If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.
Independent variable: _______
Dependent variable: _______
Answer/Explanation:
Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.
Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.
In the above given hypotheses, the dependent and independent variables are shown below:
1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".
"Risk for lung cancer" => dependent variable
Number of cigarettes => independent variable
2. "number of shark attacks on humans" is dependent on "number of sharks swimming".
Dependent variable => number of shark attacks on humans
Independent variable => number of sharks swimming
3. Dependent variable => strength of bone
Independent variable => amount of milk a person drinks
Answer:
Lab: Heart Rate
Part A: Identifying Variables
The dependent variable happens as a result of values/changes associated with the independent variable.
Independent variable: number of cigarettes smoked
Dependent variable: risk for lung cancer
Independent variable: number of sharks swimming in a coastal region
Dependent variable: number of shark attacks on humans
Independent variable: amount of milk a person drinks
Dependent variable: the strength of his or her bones
Part B: Heart Rate
Hypothesis: If I hold my breath for 30 seconds, then my heart rate will
(choose 1) increase/decrease.
Independent variable: holding my breath
Dependent variable: heart rate
Part C:
The heart rate decreases because oxygen exchange in the lungs decreases.
This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.
Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.
Example: Increase in activity—jumping jacks
Hypothesis: If I do five jumping jacks, then my heart rate will increase.
Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.
Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.
Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

Drag each label to the correct location on the chart. Classify each process as weathering or erosion. PLEASE HELP me (I'm stuck) NO homo THOO
Lets do numbering of the labels to make labelling clear.
1. The Colorado River carves land in Arizona to form the Grand Canyon.
2. Cracks form in a sandstone wall surrounding a house.
3. A marble statue near the science museum is changing color due to rainfall.
4. After a rainstorm, soil and rock pieces litter the roadways.
5. The sand dunes in the Sahara Desert are changing shape.
Answer:
Weathering:
2. Cracks form in a sandstone wall surrounding a house.
3.A marble statue near the science museum is changing color due to rainfall.
Erosion:
1. The Colorado River carves land in Arizona to form the Grand Canyon.
4. After a rainstorm, soil and rock pieces litter the roadways.
5. The sand dunes in the Sahara Desert are changing shape.
Explanation:
Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.
So, on the basis of this difference we can classify each label to the correct location:
Weathering (no movement of particles after degradation):
2. Cracks in a sandstone wall of a house.
3. Changing color of marble statue due to rainfall.
Erosion (Movement of particles from one place to another):
1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.
4. Soil and rock pieces litter on roadways after rainstorms.
5. Changing shape of dunes in sahara desert.
Answer:
weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall
erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

A water strider (which can walk on water)has legs that are coated with a hydrophobic substance. What might be the benefit? What would happen if the substance were hydrophilic?
Answer:
The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.
The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.
