The terms "ecori," "haeiii," and "hindiii" refer to which of the following? (a) the voltage intensity used to prepare the electrophoresis medium (b) the restriction enzymes used (c) the organisms from which the original dna sample was obtained (d) the types of buffers used to maintain a constant ph in the preparation as the sample was processed (e) the types of proteins encoded by each fragment

The correct answer is - option B. the restriction enzyme used.

Explanation:

EcoRI, HaeIII and HindIII are the some of the restriction enzyme that are used in cleaving the DNA at specific site into fragments. It is also known as the molecular knife as it cleaves the DNA at molecular level.

EcoRI is isolated from E. coli., similarly HaeIII isolated from Haemophilus aegyptius, and Hind III isolated from Haemophilus influenzae.

Thus, the correct answer is - option B.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

c is the correct answer hope this !
