What distinguishes disruptive and directional selection pressures when both select for extreme genetic traits?
Stella [2.4K]

Answer:

Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.

Explanation:

Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.

Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.

Lyrx [107]

Answer: Pyruvate is reduced and NADH is oxidized.

Explanation:

Fermentation is a chemical process that involves the breakdown of carbohydrates anaerobically by the activities of microorganisms.

It is the process use in the production of foodstuffs, wine and beer. Fermentation start with enzymes activities, which breakdown sugars into lactate or two molecules of three carbon organic acid, pyruvic acid. Pyruvate is reduced to lactic acid or alcohol in the absence of oxygen and nicotinamide adenine dinuleotide+hydrogen(NADH) is oxidized . This process produces two ATP per glucose molecule.

______ make their own food by extracting compounds from the ocean.photoautotrophs,chemoautotrophs,cyanobacteria
Nezavi [6.7K]
<span>Both photoautotrophs and chemoautotrophs synthesize organic compounds from (inorganic) carbon dioxide, a process known as carbon fixation. Photoautotrophs get the energy to perform these reactions from light. Chemoautotrophs get it from electron donors such as hydrogen sulfide and ammonia. Cyanobacteria, by contrast, convert nitrogen from the atmosphere into ammonia, a process known as nitrogen fixation.</span>

Explain why red blood cells are unable to replace damaged proteins
Harman [31]


The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as nucleus, ribosomes and mitochondria which are crucial for protein synthesis, assembly and repair. In other words they lack both the information and the machinery for making or repair of proteins.

Due to  lack of DNA and cell organelles, red blood cells cannot be able satisfy the central dogma which  summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes  in the cytoplasm,  then translating or decoding  this information, which results in the making of  protein.
