Answer:
A. Layer A is the troposphere and Layer B is thermosphere
Explanation:
The troposphere is the lowest layer of the atmosphere. THis is where all life life resides and where weather occurs as well. It contains the air we breathe. As we go higher in the troposphere, the temperature goes down.
The thermosphere is part of our atmosphere but it is very high up and considered to be part of outerspace as well. It is heated up by the UV rays and X-rays that it absorbs.
Answer:
Related to the Stomach
Explanation:
Gastric carcinoma is also referred to as Stomach cancer. It occurs when cancerous cells starts to grow in the inner lining of the stomach. Symptoms may include pain in the stomach and indigestion.

Answer:
The correct answer is: c) the heart rate slowed and eventually stopped.
Explanation:
The vagus nerve (X) is a cranial nerve with the function to parasympathetically <u>innervate the heart, the lungs and the digestive tract. </u>
As a part of the Autonomic Nervous System (ANS), the vagus nerve regulates things such as heart rate and gastrointestinal peristalsis (things we cannot control).
Given that it is a component of the parasympathetic division of the ANS, it stimulates the organs when the individual is performing normal activities like <u>resting and feeding</u> (unlike the sympathetic division, responsible for the fight-or-flight response). For this specific reason, the vagus nerve slows the heart rate, so if it were to be stimulated in a frog, it would produce the same thing and ultimately lead to its heart stopping.
There is no vascular cambium between the xylem and phloem in monocot vascular bundles. This means that no wood is produced in the annual ring.
<h3>What are annual rings?</h3>
An annual ring is a band of wood that can be seen in a cross-section of the stem or root of a temperate plant. It represents the annual growth of a plant. It represents a plant's growth over a year. Annual rings form as a result of vascular cambium activity during intrastellar secondary growth.
The study of tree growth rings can be very useful for determining the age of a specimen as well as understanding past hydrological phenomena as well as understanding geomorphological phenomena such as movements or landslides. The study of these rings can also be used to study and reconstruct the past and present climate of a specific area.
