Answer:
According to scientists , water occupies up to 60 % of the human body .
The importance of water in the human body are ;
- Transport
- Formation of bodily fluids i.e. saliva
- Digestion
- Regulates body temperatures
- Circulation of nutrients
Explanation:
The reason why it is important to maintain good fluid balance within and without he cells is because , It can dissolve various elements to make then easily absorbed into other system .There are many fluids which rely on water for volume e.g. blood which is the main component of the circulatory systems , water also regulates the temperature and heart pressure ,
Through electrolysis , fluid balance in the cells can be achieved and it also helps to generate nerve impulses .
Answer: it produced oxygen as a waste product
Explanation: there was more free oxygen
Breast milk has been known for making healthier babies. Nucleotides found in human breast milk has been shown to boost the immune system in infants.
Answer:
It would most likely render the protein nonfunctional or mis-functional.
The mutation could result in three outcomes:
- Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
- Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
- Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.
Answer:
Half would have the genotype Aa.
Explanation:
Given that the genotype of both of the parents was "Aa"; both parents would make two types of gametes. The 50% gametes from each parent would carry allele "A" while the rest 50% gametes from each parent would carry allele "a".
The random fusion of gametes of two parents would give the progeny with genotype ratio 1/4 AA: 1/2 Aa: 1/4 aa.
