What are the 4 processes involved in the formation of sedimentary rocks? The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. What is the correct order of the processes responsible for the formation of sedimentary rocks? The order for the formation of sedimentary rocks […]

How do you manipulate variables in an experiment? A manipulated variable is the independent variable in an experiment. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one manipulated variable at a […]

Is a 0 GPA possible? Is it possible to have a negative GPA? No. The lowest grade you can get, an F, is a 0. However, while it theoretically is possible to have a GPA of 0, it is impossible to graduate with a 0 GPA as an F means that you don’t receive credit […]

What is the density of lead? The density of liquid lead is 10.678 g/cm 3 at its melting point (600.6~K), and 8’803 g/cm 8 at its boiling point (2024°K). What does one cubic inch of lead weigh? 0.409 What does 5 gallons of lead weigh? A five gallon bucket weighs right at 300 lbs. What […]

Why does higher biodiversity cause an ecosystem to be more sustainable? Why does higher biodiversity cause an ecosystem to be more sustainable? There are a greater variety of genes and species in the ecosystem. Which is an example of biodiversity in an ecosystem? Having a diverse array of living organisms allows other organisms to take […]

What is the purpose of an egg drop experiment? Purpose: To explore concepts of momentum and collision by developing a container to lessen the force of impact when an egg is dropped from a high place. What can you do to keep a falling egg from breaking in impulse terms? Lead a discussion and analyze […]

What happens when distilled water enters the bloodstream? Distilled water doesn’t have any solutes. Distilled water is going to dilute the plasma so as the water flowing into the blood vessel then were starting see the plasma concentration drop. Blood cells take up water, enlarge finally they’re going to burst open. What type of environment […]

Can a body moves with a certain velocity but its acceleration is zero? Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. What is acceleration […]

What is the independent variable in an experiment example? In experimental research, the independent variable is manipulated or changed by the experimenter to measure the effect of this change on the dependent variable. Experiment example You are studying the impact of a new medication on the blood pressure of patients with hypertension. What is a […]

Who Theorised evolution? Charles Darwin Who was the first to talk about evolution? In the early 19th century Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin’s On […]
