A glow stick is an example of this
These brain activity during stage 2 of sleep are called
sleep spindles. These are sudden bursts of brain activity from the reticular nucleus of the thalamus. In an EEG tracing, these look like fluctuations of voltage (see attached image). Sleep spindles do represent time periods wherein the thalamus inhibits conscious processing hence keeping the person in the asleep state.
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.
No. The recorded drop in water in the pipet of the potometer would have been used not only for plant transpiration, but also to return the plant cells to a turgid state. Turgid means to expand<span> due to high fluid content. Plants are required to maintain turgid cells to maintain an upright position as loss of turgidity results in plant wilting.</span>
Answer:
a) Stick/palm ribs/ coconut fiber which represented the water and oceanic/sea wave patterns
b) Stone/coral pebbles / shells to represent the land.
Explanation:
Polynesian stick chart is a form of navigational tools used to discover the sparsely distributed island. They predominantly used following elements
a) Stick/palm ribs/ coconut fiber which represented the water and oceanic/sea wave patterns
b) Stone/coral pebbles / shells to represent the land.
The combination of these stick and pebble was used to represent the interaction of ocean waves with the island. However, these navigational charts did not represented an exact weather condition.
