A) BIO provides a larger field of view than Direct Ophthalmoscopy B) Direct Ophthalmoscopy has a larger depth of focus than BIO C) Direct Ophthalmoscopy has more magnification than BIO D) BIO provides a real, inverted image E) Direct Ophthalmoscopy provides a virtual, upright image - -B (BIO has larger depth of focus) Does BIO o...

Transverse waves The vibrations are at right angles to the direction of travel. Longitudinal waves The vibrations are along the same direction as the direction of travel. Examples of transverse waves Light and other types of electromagnetic radiation, as well as water waves and S waves (a type of seismic wave). Examples of longitudinal waves Sound waves and waves in a stretched spring, and P waves. Equation linking time, period and frequency Period = 1/frequency Equ...

AQA A-Level Biology. 3.2 – Cells questions and answers 100% guaranteed success. Structure of Nucleus. - correct answer. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small...

Reflection : The bouncing back of a wave when it hits a surface through which it cannot pass. Transmission : the passage of light through an object Interference : the combination of two or more waves that results in a single wave Diffraction : The bending of a wave as it moves around an obstacle or passes through a narrow opening Refraction : Change direction and or speed refractive index : a measure of the light-bending ability of a medium 2 | P a g e Refractive index equation :...
