Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.

2) Chemical substances in food dissolve in saliva
Substances form the food need to be dissolved and and a little bit degraded (by teeth and some of the enzymes in the mouth) in order to react chemically with taste receptors
1) Taste receptors are stimulated
Taste receptors are located in the oral cavity, usually on the tongue but also pharynx and the epiglottis (receptors are placed on taste buds within papilla on tongue)
3) Signals are sent to the thalamus by the facial nerve
From the ventral posterior medial nucleus in thalamus sensation is projected to the gustatory cortex
4)The gustatory cortex processes taste perception
The sensation of taste includes: sweetness, sourness, saltiness, bitterness, and umami
Answer:
20%
Explanation:
Given that:
Actual weight of 1 mL of water =. 1g
Average weight using :
TOOL A = 1.2
TOOL B = 1.5
Percentage Error of TOOL A:
(|approximate measurement - actual measurement| / actual measurement) * 100%
(|1.2 - 1| / 1) * 100%
(0.2 / 1) * 100%
0.2 * 100%
= 20%
