A redshift is when light or other electromagnetic radiation from an object moves away from the observer.
The Cenozoic Era started about 66 million years ago with the mass extinction of dinosaurs. Because of this, D could not have been true during the Cenozoic Era.
Trilobites and shellfish are both far more primitive than dinosaurs, even, and would also have evolved before the Cenozoic.
The correct answer would be A. First of all, it has the word modern in it. Second of all, the birds we know today would have certainly been a lot different 66+ mya.
Answer:
Telomerase acts to elongate the 3' end of linear DNAs.
Explanation:
The 5' ends of the linear DNA can not be replicated by DNA polymerase due to the absence of free 3' end to be elongated. This is prevented by the action of telomerase enzyme which contains both RNA and protein components. The RNA component of the telomerase is 150 nucleotides long.
The telomerase enzyme elongates the 3' end of the template strand by using its inbuilt RNA template. Since it uses an RNA template to make the DNA copies, it is a reverse transcriptase. Repeated translocation and repositioning of the enzyme elongates the 3' end of the template DNA.
The RNA primase makes the RNA primer at the end of the new telomere strand which is then elongated by DNA polymerase. DNA ligase seals the nick. In this way, telomerase serves to prevent the loss of 5' ends of linear DNA in successive rounds of DNA replication.
Answer:
Binocular cues
Explanation:
Binocular cues are visual perceptions taken by the two eyes with the visual information sent to the brain at the same time
Answer:
<em>Rattus rattus</em>
Explanation:
It's the scientific name of the Black rat. It belongs to under the kingdom of Animalia. It is also known as roof rat, ship rat, or house rat. It is a long-tailed rodent. They are black to light brown with a lighter color underside. There is another type of black rat called Tamed black rats. They are sometimes kept as pets.
Black rats are generally omnivorous. They are harmful to farmers because they eat various types of crops. So, for removing Black rat from the crop fields, farmers follow different types of protective ways.
