He would say that Lamarck's theory is wrong. Lamarck's theory stated that traits that are used are passed on to the offspring. In other words, if an organism changes during its lifetime in order to adapt to its environment, then its changes will be passed on to its offspring. This is wrong because this means that organisms pass on traits based on genetic information and not based on the environment of the offspring.
Hope this helps.
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.
A-The composition of their cell walls
Explanation: plant cell walls components is glucose. Fungi cell will components is chitin
Anaerobic respiration.
<span>Anaerobic respiration is a type of cellular respiration BUT does not use oxygen (O2). It is used when there is not enough O2 for aerobic respiration.
</span><span>It can be summarised by the equation: glucose → lactic acid (+ energy released). However, it releases less energy than aerobic repspiration due to a lack of oxygen resulting in an INCOMPLETE breakdown of glucose.
