You’ve likely heard of polar bears (Ursus maritimus) and grizzly bears (Ursus arctos horribilis). Have you heard of a grolar bea

Karolina [17]

Answer:

allopatric speciation.

Explanation:

When the population belonging to the same biological species becomes separated from each other due to some geographical factor such that no gene flow can occur between the two separated populations then the speciation that occurs on account of this is known as allopatric speciation.
The geographical isolation that separates the two groups can be the origin of a mountain, the formation of islands, volcanic eruption, etc. which prevents the two groups fro mating with each other and ultimately causes their lineage to speciate.
Although the two separate populations are unable to mate due to geographical factors, if the two populations are allowed to mate again, given that they have not been separated very long ago, they can give rise to hybrids.
Thus, in the given question it is given that polar bears and grizzly bears have been mated and hybrids have been produced and this points out to the fact that polar bears are result of allopatric speciation.

Describe the processes of transcription and translation in your own words, based on what you have observed in the Gizmo.

Flura [38]

Answer:

Please find the explanation of transcription and translation below using the key words.

Explanation:

Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called RNA POLYMERASE, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand.

Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the RIBOSOME where a group of three nucleotides in the mRNA called CODON is read by another group of complementary nucleotide in the transfer RNA (tRNA) called ANTICODON. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.
