The answer is B)<span> </span>temporal isolation.

<span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>
Water is an excellent solvent because its polar water molecules form hydrogen bonds with ions and polar molecules, allowing ionic and polar covalent compounds to disperse easily in water.
The right option is; c. many days of cloudy, wet weather
A stationary front is a pair of air masses that forms when a cold front or warm front stops moving because neither of them is powerful enough to move the other. A stationary front may stop moving for days and it can cause a cloudy weather with significant amount of rain or snow, especially if the front occurs in a region that has low atmospheric pressure.
1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.
tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with the amino acids they encode.tRNA has anticodone that binds to mRNA codone.
2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.
Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).
3. Initiation of translation always happens at the start codon of the mRNA.
Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).
4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.
These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.
5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.
Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
