 the kt event set the stage for the Cenozoic era that began 65 million years ago however as the dinosaurs perished at the end of the cretaceous the mammals took the center stage. even as mammals increased in numbers and diversity, so did the birds, reptiles, fish, insects, trees, grasses, and other forms of life.

The stages of mitosis were originally defined by cellular features observable through a light microscope.
Brrunno [24]

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

if the following mRNA strand were produced during transcription what amino acids would be found in the protein GGCUACGGGCAUCAC
ioda

The correct answer to your question is B. Glycine-Tyrosine-Glycine-Histidine-Histidine.

You can find this by taking groups of codons starting with the first group (GGC). GGC is located under Glycine so Glycine will therfore be an amino acid found in the protein. Continue doing this with the next codons to come up with the answer.

I hope this isn't too late and still helps!
