During the notation of isotopes, Atomic number (Z), and atomic mass (A) are used distinctly.
What do you mean by Isotopes?Isotopes may be defined as a member of a family of an element that all have the same number of protons but different numbers of neutrons.
[tex]_14X^3^4[/tex], indicates that atomic number is 14, while atomic mass is 34, where X is Silicon. [tex]_XP^3^6[/tex], indicates that the element is Phosphorus, atomic mass is 36, while X is 15 which is atomic number. [tex]_XMN^5^7[/tex], indicates that the element is Manganese, atomic mass is 57, while X is the atomic number which is 25. [tex]_5_6X^1^2^1[/tex], indicates that the atomic number is 56, while the atomic mass is 121, where X is Barium.

How does the exchange of oxygen and carbon dioxide occur in the lungs and tissues ?
Answer:
Gas exchange happens in the alveoli in the lungs and the capillaries that envelop them. When you inhale oxygen, this one moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. In simple words the exchange comes from the inhalation and exhalation of gases

Where do the storms hit the hardest in europe?
Answer:
The effects of tropical cyclones in Europe and their extratropical remnants include strong winds, heavy rainfall, and in rare instances, tornadoes or snowfall. There are only two modern cyclones officially regarded as directly impacting mainland Europe while still fully tropical or subtropical: Hurricane Vince in 2005, which struck southwestern Spain as a tropical depression; and Subtropical Storm Alpha in 2020, which made landfall in northern Portugal at peak intensity. Hurricane Debbie in 1961 may have still been tropical when it made landfall in northwestern Ireland, but this is disputed.[nb 1] In 1842, it is believed that a hurricane struck Europe.
define open and close type of circulatory system which is found in men
Open Circulation:
Open circulatory systems are common to most arthropods and mollusks. They have a heart that pumps blood into a hemocoel. The blood then diffuses back into the blood vessels.
Tissues tend to be surrounded by blood, and the blood flows freely throughout the body tissues. In this type of circulatory system, blood tends to be sluggish because it is diffusing rather than readily being pumped through vessels.
Animals with an open circulatory system tend to be small organisms, so the blood doesn’t have far to travel. These animals typically have low metabolisms. They don’t tend to need quick energy or immune defenses.
Closed Circulation:
In a closed circulatory system, the blood stays within blood vessels. In this way, blood is kept separate from body tissues. This system has a heart that pumps blood through a continuous circulation pattern. As such, the blood tends to be pumped at a higher pressure.
In organisms with a closed circulatory system, the blood does not fill body cavities. Many vertebrates, such as humans, have a circulatory system known as the cardiovascular system and a secondary system known as the lymphatic system.
Animals with a closed circulatory system tend to be larger than those with an open circulatory system—consider, for example, an elephant versus a grasshopper. This type of system can transport blood to extremities while maintaining a higher blood pressure than the open circulatory system.
There are several different heart configurations for an animal with a closed circulatory system. Most mammals have a four-chambered heart, which separates the oxygenated blood from the deoxygenated blood. A fish has a two-chambered heart, which pumps blood directly to the gills to become oxygenated and then throughout the body. Amphibians have three-chambered hearts, where oxygenated and deoxygenated blood mix within the heart before being pumped to the body.
