The water in freshwater ecosystems like lakes, ponds, creeks, and rivers are more likely to freeze over in winter because it doesn't contain salt. The salt dissolved in marine environments prevents the water from freezing.

Because it is easier for fresh water to freeze and also the water in the environment will freeze

Translation

sertanlavr [38]

A- growing polypeptide B- Lone amino acid

C- tRNA D- Anticodon

E- mRNA F- Small ribosomal subunit

G- codon H- Large ribosomal subunit

Explanation:

Methionine (start codon) , leucine, methionine, arginine, aspartic acid, glycine, glycine, leucine, histidine, stop codon

Three types of RNA that takes part in the translation are:

mRNA: It is formed by the process of transcription. The DNA strand is copied as mRNA with help of RNA Polymerase. The mRNA strand is single- stranded and consists of codons which code for amino acids for the protein synthesis. Not full sequence of mRNA codes for amino acid chain there are non-coding regions called introns which are removed during splicing and only exons code for the amino acid sequences.

tRNA: It brings the correct amino acid to the growing polypeptide chain by reading the codons from the mRNA. It has anticodon which helps in bringing the correct amino acid coding to mRNA sequence.

rRNA: rRna plus protein and ribosome makes up rRNA. The ribosomes are called protein factory, because growing polypeptide chain is formed here. They are responsible for reading the correct amino acid bonding to form polypeptide. They are having two subunits smaller and bigger depending on their sedimentation rate by centrifugation.

In eukaryote,s protein synthesis occurs in the ribosomes which are present in the cytoplasm of the cell.

B. All the three nucleotides that code for amino acid are important because any base difference in amino acid will change the protein formed due to amino acid difference.

Horses and donkeys can mate but they produce a mule, which is always a sterile animal. This means that they cannot produce viabl

Morgarella [4.7K]

They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
