At the superior end of the esophagus, the superior esophageal sphincter is a thickened ring of ______ muscle marking the area where the esophagus and the pharynx meet.
The superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.
What is the superior esophageal sphincter?
It is located immediately after the pyriform sinuses, it is a muscular ring located in the high pressure area between the pharynx and the esophagus.
This prevents the passage of air into the digestive tract during inspiration and the reflux of gastric material into the pharynx, relaxing to open the esophagus.
In order for a muscle-building athlete to keep muscles in good shape, it is necessary to synthesize more muscle protein than is consumed, which is known as nitrogen balance..
Therefore, we can conclude that the superior esophageal sphincter is a muscular ring that separates the pharynx from the esophagus, has voluntary activity and is responsible for initiating swallowing.

Describe the relationship between rocks and fossils found in the same rock layer.
Answer:
The three concepts are summarized in the general principle called the Law of Fossil Succession: The kinds of animals and plants found as fossils change through time. When we find the same kinds of fossils in rocks from different places, we know that the rocks are the same age. Scientists look for ancestors and descendants through geologic time.
Explanation:
Water has several properties that make it unique amongst compounds and make it possible for all forms of known life to function. The graph provided depicts what happens to the density of water as the temperature gets colder. According to the graph, what happens to the water’s density as it freezes and why? (SC.912. L.18.12)
When the temperature of the water finally goes below 4°C, the density of water decreases and as a result ice does not sink. The surface water freezes at 0°C while the lower part remains at 4°C
When the temperature of the water finally goes below 4°C, the density of water increases and as a result, ice doesn’t sink. The surface water freezes at 0°C and the water below freezes as well, allowing life to exist below frozen lakes
Water continues to get denser as the temperature get colder
The properties of cohesion and adhesion are directly responsible for water expansion at 4°C allowing aquatic life to survive under frozen lakes
Water’s density increases as it freezes or at lower temperature which is a unique property of water that enables aquatic animals to survive.
How cold water has more density?Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.
So we can conclude that cold water is more dense and will sink in room-temperature water.

List all the gametes that are possible with each of the following genotypes.
a. Aabb
d. AABb
b. AaBB
e. AAbb
C. AaBb
f. aabb
All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.
Gametes formationThe formation of gametes for a dihybrid involves the crossing of the two traits involved.
Thus: Aabb is equivalent to crossing Aa and bb
Aa x bb
Ab Ab ab ab
Hence, all the gametes would be Ab or ab.
For AABb: AA x Bb = AB Ab AB Ab
The gametes are either AB or Ab
For AaBB: the gametes are either AB or aB
For AAbb, only Ab gametes are produced
For AaBb: the gametes would be AB Ab aB and ab
For aabb: only ab gametes are produced.
