<span>The answer is I, II and III. These microbes can be funds even in hydrothermal vents at the bottom of ocean trenches where they convert chemicals to organic matter. Most are critical in the many nutrient cycles such as the nitrogen and carbon cycles. These microbes form the base of the food chain since they support higher organisms such as paramecium which are in turn eaten by higher organism such as amoeba. The amoebas are then fed by tadpoles, for example, and the tadpoles are eaten by fish…and etcetera. </span>

Place the terms into the correct column that describes the reactions of photosynthesis.
MAVERICK [17]

Answer:

In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.

- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.

During what stage does land get ready for the arrival of a new species
34kurt

Answer

           The correct option is B.

Explanation

          Ecological succession of any species is composed of following stages:

A. Migration

            The movement of species from one place to another location for the purpose of setting permanently o temporary is known as migration . Forexample

             Siberian crane (<em>Leucogeranus leucogeranus</em>) that live in the arctic tundra of eastern and western Russia. The eastern population of birds migrate to china while western population of these birds migrate to Iran, India and Nepal during winter season.

B. Ecesis

         The complete establishment of species in new habitat that was completely barren or left barren due to some catastrophe is known as Ecesion. This process is dependent upon the climatic, edaphic and biotic factors. The success of plant depend upon some of the adaptations to withstand the unfavorable conditions which includes both biotic and abiotic conditions.

Forexample

               The process of succession in xerosphere start on barren area from pioneer stage covered by crustose lichen, then foliose lichen followed by moss stage, herbaceous stage and a last by shrub stage.

C. Nudation

       The initiation of new species by major environmental disturbance such as volcano eruption is known as Nudation.

D. Reaction

            It represents the effect of established species on the habitat. Forexample plants alter habitat condition as they grow. They extract raw materials from the environment in large amounts and return metabolic wastes. The waste accumulates in large amounts and differ from the original raw materials, thus altering the environment.  

E. Competition

             The phenomenon which involves struggle for existence between two or more individuals growing in same area, that make excessive demand that are similar in nature on the soil is known as competition.

Such struggle may be in between same species or different species. The competition may be interspecific or intraspecific. Because of completion the weak individuals are eliminated as strong ones are retained.

How does antibiotic resistance arise? how do hospitals and feedlots contribute to this phenomenon?
Stella [2.4K]
<span>Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Subsequent generations of such organisms develop resistance to the antibiotic. Hospitals' overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.</span>
