Answer:
D
Explanation:
Example the action of teeth on food in the mouth increase surface area for salivary amylase to start digestion of starch
Answer: Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism.
Explanation:
Answer: b. Remains of formerly living things buried by sediments in regions with little oxygen.
Explanation:
Fossil fuels are underground geological fuel deposits which are formed from the decaying of organic materials (animals and plants) over hundreds of millions of years in the earth's crust, which furthur processed into coal, crude oil, heavy oils or natural gas by exposure to pressure and heat
Fossil fules are present only in sedimentary rocks under litte oxygen the provide temperatures and pressures that do not kill fossil remains, unlike most igneousand metamorphic rocks.
Hence, the correct option is b.
Answer:
Due to gluten intolerance.
Explanation:
Gluten is a protein present in the food items like wheat, barley and bread. Nearly 1% of the population are unable to digest the gluten protein.
The gluten intolerance people feel bloated as gas build up in their body after the consumption of wheat. This may leads to uncomfortable and health problems in gluten intolerant people. This is a type of auto-immune disease.
Thus, the correct answer is gluten intolerance.
The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.
