You are given a prepared slide and are told that it is a streptobacillus. without even looking at the slide under the microscope, you know which of the following? 1. the bacteria are linked together in chains. 2. the bacteria are spherical in shape. 3. the bacteria are in grape-like clusters. 4. the bacteria are rod-shaped. 5. the bacteria are gram-negative.
a) 1,2.
b) 1,4.
c) 2,3.
d) 2,4.
e) 1,4,5.

1 and 4

Explanation:

Streptobacilli are linked together in chains, the bacterium is gram positive and   the generally rod-shape. The genus could be aerobic ( required oxygen for their growth), falcultative anaerobe (in the absence of oxygen, they can switch to fermentation).

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.
