Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks.
Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris.
Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.
Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.
Photos and brief descriptions of some common sedimentary rock types are shown on this page.
Answer:
D. Use the polymerase chain reaction
Explanation:
Polymerase chain reaction (PCR) is a molecular technique used to make multiple copies or amplify a particular DNA sample. This enables scientist conduct thorough genetic analysis on minute sample of DNA, simply by amplifying it to a large quantity.
The PCR machine is usually used to amplify DNA fragment. The DNA fragments undergo three major steps successively: denaturation, annealing and elongation
Answer:
The correct answer will be-
1. Parietal lobe
2. Temporal lobe
Explanation:
Parietal and temporal lobes are the lobes of the cerebral cortex of the brain which are important to the sensory information and analysing the sensory information.
The somatosensory cortex of the parietal lobe processes the touch sensation in the body and help identify the location of the touch in the body.
The temporal lobe organizes, analyse and transmits the signals in response to the sensory information.
Thus, Parietal lobe and Temporal lobe are correct.
Planktonic algae are primary producers so your answer is A. :)
