Had to look for the options and here is my answer. The potential disadvantage that I can see that might be essential to reconsider when cloning a large group of cows is that lack of variation may result in the limitation of the survival of the herd. Hope this answer helps.
The answer is B.chlorophyll b you welcome.
Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
Answer: Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).
The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles.
Only a small amount of light penetrates beyond this depth.
The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible.
The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness.
‘Photic’ is a derivative of ‘photon,’ the word for a particle of light.
Answer:
<u>The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.</u>
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.
