the sun is solar power which gives you natural energy
Answer: true
Explanation:
Only the mRNA made from the DNA takes part in the protein synthesis
Answer:
four amino acids are produced from 15 nucleotide sequence which includes last three nucleotides for stop codon.
Explanation:
Every three nucleotides makes one codons that encodes one amino acid. As in this question there are only 15 nucleotides and each 3 nucleotides makes one codon hence only 4 amino acids are encoded by this sequence. Last three nucleotides for stop codon which does not encodes an amino acid.
Answer is 15 nucleotide sequence encodes 4 amino acids and one stop codon
<span>The avian heart has evolved into a large and powerful organ with rapid muscular contractions. Generally the smaller the species the larger the relative heart size. Generally birds have hearts larger and ones that beat faster than mammals. The human heart weight amounts to .42 percent of body weight and the pulse rate at rest averages 72 beats per minute. The House Sparrow's heart constitutes 1.68 percent of the body weight and the pulse rate at rest averages 460 beats per minute. In the Ruby-throated Hummingbird these figures rise to 2.37 percent and a pulse rate of 615.</span>
D.
D. Mitosis involves the splitting of a cell and its content. According to the State University of New York, mitosis has five phases: interphase, prophase, metaphase, anaphase and telophase. During interphase, the cell prepares for mitosis, and chromosomes are usually not visible. In prophase, the chromosomes start to coil, the nuclear membrane wanes and a spindle-like formation appears. In metaphase, the chromosomes align for replication. In anaphase, the chromatid separates, doubling the number of chromosomes to 92. In telophase, the chromosomes uncoil, the nuclear membrane reappears and the cell splits into two daughter cells, each having 46 chromosomes..
