Carbon film fossil is the type of fossil that preserves delicate details of an organism after pressure squeezes out liquids and gases.
Carbon film fossil is a type of fossil that is mainly composed of carbon and can preserve delicate details of organism’s (animal and plants) parts. The formation of carbon film fossil starts when a dead organism is buried under sediments. After some time, the organism will begin to decay in a process known as carbonization. Pressure will squeeze out liquids and gases from the dead organism, leaving behind a layer of carbon. Carbon film fossils usually appear black or brown in colour.
BLINK protein speeds up stomatal movements in response to light fluctuations resulting in improved plant growth and water use.
Plants can't move, so their “blinking” helps protect them from burning or bleaching when they are in bright sun.
I'm not sure if the first part is right, but I do know the second part is.
Answer:
By 1900, Fingerprint was the evidence which was collected at crime scenes to help positively identify suspects by one particularly unique trait. No two people can have the same type of fingerprints. It is a unique characteristic which is even not common among identical twins. Therefore, was considered as an important evidence for identification of suspects and linking them with the scene of offence. In 1904, the city of St.Louis, Missouri used fingerprint evidence for the first time for criminal identification.
Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
PCR allows for the analysis of DNA fragments through the comparison of the base pairs each molecule contains, which can then be used for genetic screening and the identification of individuals and DNA fragments
