The correct answer is option B that is neutrons.
The atomic mass refers to the mass of an atom of a chemical element articulated in atomic mass units. It is about the same to the number of protons and neutrons in the atom (the mass number) or to the average number permitting for the relative abundances of distinct isotopes.
The atomic mass of a single atom of an element is determined by supplementing the mass of protons and neutrons.
Atomic mass is calculated by the sum of number of protons and the number of
Further explanation:
The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty and its mass is concentrated inside a small region called the nucleus.
Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The sum of protons and neutrons are called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in fixed orbital path. The positively charged subatomic particle is called proton. Neutron is a subatomic particle that has no charge. Electron is the negatively charged subatomic particle. The number of electrons is equal to the number of protons in a neutral atom.
An atom is written as , where A is the atomic mass or mass number, Z is the atomic number, and X is the letter symbol of the element.
The total positive charge is known as the atomic number. It is represented by Z and is also equal to the number of protons present in the nucleus of the atom.
Atomic mass is the total number of nucleons within the atomic nucleus. It is also known as the mass number. Protons and neutrons together are known as nucleons because these are located in the nucleus of the atom. So atomic mass is the sum of number of protons and neutrons in the nucleus of an atom. Hence option (B) is correct.

The correct answer would be the animal is visually appealing.
Endangered species are those which are on the verge of extinction in near future and require immediate steps for their conservation.
The principal threats to the species are:
- Loss of habitat due to human intervention such as deforestation, building of dams, agriculture practices et cetera.
- Spread of invasive species.
- Increased pollution and global warming.
- Unsustainable hunting of animals for products like fur, tusks, meat et cetera.
- Diseases
The visual appearance of an animal is not a threat to the organism and thus, it does not determine if an animal should be placed on the endangered species list.

Trachea, bronchi, capillaries, alveoli
Capillaries, trachea, bronchi, larynx
Alveolar sacs, bronchi, trachea, pharynx
Answers
Alveolar sacs, bronchi, trachea, pharynx is the list that describes the path carbon dioxide takes to the nose. Thus, option D is correct.
What is the respiratory system?
The respiratory system has been refers to the system of the organs and tissues which would work together to take in oxygen into the cells and remove carbon dioxide from the body. Parts of the respiratory system include the lungs, the bronchi, trachea, etc.
The path of the carbon dioxide as it leaves the body describes the path through which carbon dioxide takes as it goes from the capillaries to be exhaled via the nose or mouth. During the inhalation through the nose or mouth the air first enters the "pharynx" which is also called as throat, then the air moves towards the "larynx" . Is a passage between the pharynx and the trachea.
Carbon dioxide would follows the following path on the leaves the capillaries: alveoli--->bronchioles--->bronchi---> trachea --->larynx --->pharynx---> mouth/nose
Therefore, Alveolar sacs, bronchi, trachea, pharynx is the list that describes the path carbon dioxide takes to the nose. Thus, option D is correct.

Answer:
C. Bronchial
Explanation:
The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.
The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.
The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).
