What structures do both plant and animal cells? Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements. What is the difference between nutrition in […]
What are the two main ideas of the kinetic molecular theory of matter?
What are the two main ideas of the kinetic molecular theory of matter? The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic […]
What are the three main reasons for seasons?
What are the three main reasons for seasons? We have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The Earth’s axis is tilted at an angle of 23.5 degrees….Winter Months Tilt. Revolution – The Earth revolves around the Sun. The North Pole always POINTS in the Same […]
Is Togo like Balto?
Is Togo like Balto? Though Balto often gets the credit for saving the town of Nome, it was Togo, a Siberian Husky, who led his team across the most dangerous leg of the journey. Named after Heihachiro Togo, a Japanese Admiral who fought in the war between Russia and Japan (1904-05), Togo was the lead […]
Why are heat islands dangerous?
Why are heat islands dangerous? Heat islands contribute to higher daytime temperatures, reduced nighttime cooling, and higher air-pollution levels. These, in turn, contribute to heat-related deaths and heat-related illnesses such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke. What causes a heat island? How Do Heat Islands Form? Tall buildings […]

How do you find the hypothesis in a research study?
How do you find the hypothesis in a research study? The first few paragraphs of a journal article serve to introduce the topic, to provide the author’s hypothesis or thesis, and to indicate why the research was done. A thesis or hypothesis is not always clearly labled; you may need to read through the introductory […]
How long does science advances take?
How long does science advances take? At Science Advances, we ask reviewers return their evaluations within two weeks, although assigning editors may change that time parameter. Editors may ask the same or new reviewers to assess a manuscript after it has been revised after review. Is it hard to publish in Science advances? Submitting a […]
Does pressure decrease with expansion?
Does pressure decrease with expansion? Pressure–Volume Work During an expansion (Figure 12.5), an increase in volume decreases the internal pressure of a system as the system does work. Does pressure change in adiabatic free expansion? Adiabatic free expansion of a gas Because there is no external pressure for the gas to expand against, the work […]
