The three sources of energy include,

Solar energy

Wind energy

Water and geothermal.

Energy is termed as the capacity of physical system to do work. It exists as kinetic or mechanical energy, light potential energy, electrical and heat.

Source of energy can be classified as renewable and non-renewable.

The renewable is derived from natural processes which replenished constantly, for example, solar energy, biomass, ocean, hydropower and wind.

The solar energy it is sustainable to mean that it does not run out but it is maintained reason being that sun shines every day.

A good advantage of solar is that it is natural and available in plenty, and non-pollution. Wind energy helps to turn the blades of windmills as it turns shaft to where they are attached.

Someone new is preparing media for lab and adds buffers to the EMB agar that raise the pH to 7.8. The starting pH of EMB plates

mestny [16]

Answer and Explanation:

Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.

It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.

Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.

In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.

treatment for PTSD campus be described A.multumodal multi-phasic b. atheoretical C. stress inclusion D.eclectic

Sloan [31]

Answer:

A. multimodal and multiphasic

Explanation:

Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.

Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.

Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy, which typically involves the use of hypnosis in psychotherapy to treat medical conditions such as depression, eating disorders, anxiety, post-traumatic stress disorder (PTSD).

The treatment for post-traumatic stress disorder (PTSD) can be described as multimodal and multiphasic because it is characterized by series of activities and it takes place in various phases.

If someone told you that plate tectonics is just a theory and that it hasn’t been accepted as a law yet, how would this informat

ch4aika [34]

Answer: There are few ‘laws’ in science. Those ‘laws’ are so named for historical reasons, but they are theoretical in nature. They set out what happens when a theory is applied in practice. A theory is simply the best explanation we have for understanding why some process takes place and predicting what the result will be.

Explanation: Anyone who describes something as “just a theory” does not understand what a theory is. Laws are arbitrary human rules. Theories are severely tested and re-tested explanations of why things happen in the real physical world and can be used to make predictions about outcomes.

Some would say that theories are about why something happens and laws (in science) describe what happens. But this simply makes a scientific ‘law’ a subset of a scientific theory, explaining how to make predictions.
