Which best explains how photosynthesis is helpful to humans? Which best explains how photosynthesis is helpful to humans? It reduces the amount of harmful rays released by the sun. It increases the levels of carbon dioxide in the air. What reactants are needed for photosynthesis and respiration? While photosynthesis requires carbon dioxide and releases oxygen, […]
Why is it important to dispose of batteries safely?
Why is it important to dispose of batteries safely? To protect the environment Most batteries contain hazardous materials and can pollute the environment when disposed of in landfills or when thrown out elsewhere. Materials like lead, cadmium and mercury can poison people and animals and contaminate soils and water, and they stay in the environment […]
How can I temporarily fix my car window?
How can I temporarily fix my car window? Create A Temporary Window On the outside window, stretch a piece of clear tape from the top of the window to the bottom. Continue to layer pieces of tape across the window. A clear, temporary “window” begins to take shape. Repeat until the area is covered. Follow […]
What are the two types of graded potentials?
What are the two types of graded potentials? Graded potentials can be of two sorts, either they are depolarizing or hyperpolarizing (Figure 1). Are EPSPs graded potentials? Graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential, are called excitatory postsynaptic […]
Why do we need controls?
Why do we need controls? Controls allow the experimenter to minimize the effects of factors other than the one being tested. It’s how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area. […]
How do you prove a rhombus is a quadrilateral?
How do you prove a rhombus is a quadrilateral? To prove a quadrilateral is a rhombus, here are three approaches: 1) Show that the shape is a parallelogram with equal length sides; 2) Show that the shape’s diagonals are each others’ perpendicular bisectors; or 3) Show that the shape’s diagonals bisect both pairs of opposite […]
Which energy has the shortest wavelength?
Which energy has the shortest wavelength? Gamma Rays Which transition has the highest frequency? (ii) Energy and frequency are directly related. Therefore the highest-energy transition is also the one with the highest frequency (n = 3 —> n = 1). What is the transition Imagen of maximum frequency? 5th spectral line of Humphery series. Which […]
How far back can carbon dating date?
How far back can carbon dating date? C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible. […]
Why is the strong force so strong?
Why is the strong force so strong? The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei. As such it is responsible for the underlying stability of matter. What is most powerful force in […]
