The answers are A) ectoderm and B) endoderm.
Fertilization is a fusion of male and female gametes which leads to the formation of a zygote. The zygote undergoes mitosis and transforms into a single-layered blastula. Gastrulation is a transformation of the blastula into a two-layer or three-layer gastrula. Cnidarians are a diploblastic animal because their gastrula has only two layers - endoderm and ectoderm.
a) volume in cm³ = 20 × 42 × 42 = 35280 cm³
b) volume in m³ = 0.2 × 0.42 × 0.42 = 0.03528 m³
c) volume in ml³ = 200 × 420 × 420 = 35280000 ml³
d) volume in litres = 0.02 × 0.042 × 0.042 = 0.00003528 l³
e) Density = Mass / Volume
Mass = Volume × density
= 0.00003528 × 1
= 0.00003528 × 1000
= 0.03528 grams
f) Mass in kilo gram = 0.00003528 kg
Answer:
The importance of the AUG and UGA bases lies in the fact that the first one is a start codon and the second one is a stop codon, respectively (option a).
Explanation:
Codons or triplets are sequences of three nitrogenous bases, in the mRNA, that determine the synthesis of a specific amino acid.
- <em>AUG </em><em>is called the </em><em>initiation or start codon</em><em>, and is usually at the beginning of a peptide synthesis, in addition to encoding the amino acid methionine.
</em>
- <em>UGA</em><em> is a</em><em> termination or stop codon</em><em> found at the end of a petid chain when it is complete. UAA and UAG codons are also STOP or termination codons and, together with UGA, do not code for amino acids.</em>
The biological importance of start and stop codons is to initiate the synthesis of a protein and to stop the addition of amino acids when their size is adequate.
