Hope this helped have a nice day :)
Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
Answer:
they need a high ‘surface to volume’ ratio, which is good for exchanging materials between the inside and outside of cells. But this is probably not really the size-limiting reason, since cells vary enormously in size and surface area to volume ratios.
Explanation:
The correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of
secondary structure is:
Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer
- The structure of mature messanger RNA encoding the average eukaryotic proteins is: 5' cap, 5' UTR, coding region, 3' UTR, and poly(A) tail. Option a is the correct answer
- The correct answer choice which is extrinsic is: the TATAAT consensus sequence at the -10 posi!on of prokaryotic promoters
- The diagram solution of the coding strand, 3’, 5’, translation on, transcription replication to the last isquestion is attached
<h3>Amino acid</h3>
Amino acid can simply be defined as those organic molecules or substances which combine to form proteins. However, amino acids are generally characterized by some key features or properties; some of these properties of amino acids includes the following:
- They are soluble in water
- They are base units of proteins
- Amino acid are insoluble in organic solvent
- Amino acids are colourless
- They are crystalline solid
- All amino acids however too, have at least one acidic carboxylic acid (-COOH) group and one basic amino (-NH2) group.
So therefore, the correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of
secondary structure is:
Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer
