Silicates is the answer to this.
Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution
I believe Energy absorbing reactions are endergonic.
Hypothesis as the statement is not supported by any facts and is therefor classified as a guess to a future investigation
Answer:
By designing an experiment where the temperature on the thermometer is measured after a chosen (same) time interval when the thermometer is wrapped with the different materials and placed in the freezer
Explanation:
Experimental design
Materials given: freezer, a thermometer, samples of materials
setup:
1. The freezer is put on and made to remain at a particular temperature, mimicking the winter season.
2. Next, different materials for the coat design with equal dimensions are used to rap the thermometer whose initial temperature has been recorded in the same pattern and the thermometer is placed in the freezer and left for a certain time, which is made constant for the different materials.
3. after the time, the final temperature on the thermometer is recorded.
Result interpretation
The temperature is expected to drop after the time in the freezer, but the material with the smaller change (drop) in temperature indicates that it traps more heat hence is the best material for designing a winter coat
independent variables: type of material used
dependent variables: temperature on the thermometer
control variables: time, dimensions of materials, temperature of freezer, pattern of wrapping.
