Answer:
The environmental threat posed by the egregious amounts of plastic waste that have accumulated over the years, and that will likely continue to increase unabated.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.

Answer:
If a strand of DNA contains the bases adenine, cytosine, cytosine and guanine the order of the bases on the opposite strand is thymine, guanine, guanine and cytosine.
Explanation:
DNA contains a double strand, each of which contains a specific sequence of bases —adenine, thymine, cytosine and guanine— whose order determines the genetic information stored in this nucleic acid.
The sequence of bases on one DNA strand is complementary on the other strand, taking into account the complementarity of bases, i.e. the purines adenine and guanine are complemented by the pyrimidines thymine and cytosine, respectively:
A = T
G ≡ C
<u>So that the sequence A - C - C - G of one chain is complemented by the sequence T - G - G - C of the other</u>.
<em> Taking into account the above information, the other options can be discarded, as they do not comply with the complementarity of bases in the DNA.</em>
The protists were able to avoid lysis by having its function
of the contractile vacuole in which it helps in pumping the water which are
enough or excess to get it out of the cell. While the algae avoids lysis was
because of its cell wall that is rigid in nature.
