The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are

from systematic errors (deterministic error) or random error (not deterministic error). In this experiment‚ the group measured the diameter of sphere using different kinds of measuring devices (foot rule‚ vernier caliper‚ and micrometer caliper) in order to achieve accuracy in the scientific measurements. After experimenting‚ it was revealed that the micrometer caliper has the lowest percentage of error. 1. Introduction In the early days‚ people used mostly human body parts for measuring. And because

I did not observe a counselling session as it occurs in one on one setting‚ the Field supervisor felt that when someone else was present in the setting‚ it would interrupt the therapeutic relationship (rapport) and would reduce the level of confidentiality thus leading the client to not being able to reveal personal information and to make decisions or draw solutions. However‚ I discussed with my field supervisor about counselling‚ its practices‚ rituals‚ communications and procedures and wrote a

Should Bacteria and Archaea belong to the same Kingdom? The main purpose of this essay is to find out if Archaea and Bacteria should be classified as two different Kingdoms or as a single one. As organisms‚ bacteria and archaea both are microscopic and prokaryotic (not possessing a true nucleus). These prokaryotes are very abundant on Earth and inhabit a wide spread of areas‚ including extreme ones. Both are an example of the most ancient living cells‚ which have appeared over 3.5 billion years

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

Answer to Questions 1. Describe the type of meter movement used in the analog meters. The two analog meters—namely‚ the voltmeter and the ammeter—employ the d’ Arsonval meter movement. The movement consists essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered
