Answer: protein
Explanation: I just had this question :)
Answer:
Hydrophobic tails interact among themselves, while polar (hydrophilic) heads interact with water
Explanation:
In the first place, the polar heads of the phospholipids localized on the membrane surface interact with surrounding water molecules that also surround other cell phospholipids. Second, the non-polar tails of the phospholipids from one cell interact with molecules that repel water in the other cell phospholipid. Consequently, it forms a bilayer structure composed of two sheets of phospholipids where hydrophobic tails are arranged on the inside of the membrane, thereby allowing the interaction tail-to-tail among different cell membranes, while the polar heads of the disrupted phospholipid membranes interact together with the surrounding water.
Ans.
The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.
The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.
The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.
The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).
Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.
the answer here would be c!!!
To determine the reason for the fish death, do the following:
1. Test the water for the presence of organic substances that may be poisonous to the fish.
2. Test the dissolved oxygen concentration of the lake at different locations and at different depths.
3. Perform full toxicological examination of the lake to determine if any pollutant or poisonous chemical is present in the lake.<span />
