A 15-month-old child, equivalent to a child of 1 year and 3 months of age, should have began weaning from bottle feeding from 6 months of age. Tooth decay or dental caries are commonly associated with prolonged bottle feeding as the sugars and other substances in milk; when drank from a teat from a bottle; prolongs the exposure of teeth to the milk, leading to overgrowth of bacteria causing dental caries.
Answer:
The correct answer is b. The oldest generally accepted fossils of large animals range in age from 565 to 550 million years old.
Explanation:
The oldest one of them all is the hematite tubes, that are dated about 3.77 billion to 4.2 billion years and it's from a yet unknown bacteria.
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
point b i think, because you have to see the amount of steepness in the slope.
