Is ostrich egg a cell? Technically, the yolk of an ostrich egg is one cell though it is rather specially adapted. All the nucleotide material is contained in a small volume at the edge of the yolk. The bulk is a supply of `raw material’ that the cells of the growing embryo use to assemble […]
What does V stand for in kinetic energy?
What does V stand for in kinetic energy? v = velocity. Kinetic Energy Formula Questions. What are the determinants of kinetic energy? 1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s […]
What does the weak force attract?
What does the weak force attract? The weak nuclear force is usually responsible for turning protons into neutrons or vice versa. It also applies to more exotic particles containing strange, charm, up and down quarks. Is strong force attractive? The strong interaction is the attractive force that binds the elementary particles called quarks together to […]

What is the instrument used to measure mass?
What is the instrument used to measure mass? balance What is the instrument used to measure weight? Balance How do you accurately measure air temperature? How to Measure Temperature Correctly Place the thermometer 5 feet above the ground (+/- 1 ft.). The thermometer must be placed in the shade. Have good air flow for your […]
Is the oceanic plate thicker than the continental?
Is the oceanic plate thicker than the continental? Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The less-dense continental crust has greater buoyancy, causing it to float much higher in the mantle. What are the oceanic plates made of? Oceanic […]
What is there inside a bullet?
What is there inside a bullet? A cartridge is a combination package of the bullet (i.e., the projectile), the case (which holds everything together), the propellant (which provides the majority of the energy to launch the projectile) and the primer (which ignites the propellant). How do you write a bullet point? How to write powerful […]
Is Skin Colour an allele?
Is Skin Colour an allele? Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. The “recessive”alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced. Which chromosome determines skin color? Common variations (polymorphisms) in the MC1R gene are associated with normal […]
What is difference between line and Spectrum Spectrum?
What is difference between line and Spectrum Spectrum? Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another. Band spectra is the name given to groups of lines so closely spaced that each group appears to be a band, e.g., nitrogen […]
What are called isobars give example?
What are called isobars give example? Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons) but have the same mass number. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca. What is mass […]
