Answer:
The esophagus is a long tube that connects the mouth to the stomach
Recessive alleles. Recessive alleles are only expressed phenotypically when the offspring receive recessive genes from each parent. In other words they are only expressed phenotypically when they occur in pairs. In the presence of dominant gene they are never expressed phenotypically and the offsprings with both the recessive and dominant genes occurring concurrently are referred to as carriers.
Answer:
The correct option is <em>C. Different species can share the same common name.</em>
Explanation:
A single organism might have the many common names or it might happen that different species have the same common name in different parts of the world. Common names can be sued when people from the same country, speaking the same language are talking.
But as scientific research is carried out in all parts of the world, scientists made up the system of binomial nomenclature. Under this system, each specie is given a unique name .
Answer:
A) Times of major climate change
Explanation:
The geological time scale is based on major changes in Earth's climate history. This is because of the reason that climate governs the geological processes on Earth. In geology, we study the ages with the help of stratigraphical data where sediment deposition and the fossils it is hosting are the keys to understand the environmental conditions at that particular time. These conditions didn't change significantly unless the climate was changed. An example is the extinction of dinosaurs during K/T boundary event (mass extinction). The most likely reason is the hitting of a meteorite on Earth that changed the climate of Earth in a short period making it least favorable for many organisms to survive.
On the other hand, the occurrence of huge events cannot be used to establish a geological time scale because sometimes, the changes happen more slowly.
Similarly, shifts in the Earth orbits are cyclic however geological time scale doesn't reflect cyclic changes. The same climate can establish in different ages but these events are not used not as a criterion to establish a geological time scale.
In the end, the time span of humans on Earth is very small when compared with the overall geological time scale. Humans record exists from Pleistocene (2,580,000 to 11,700 years ago) to today whereas geological time scale starts in the Archean Eon (4.0 billion to 2.5 billion years ago).
