Which part of the upper respiratory system is known as the vocal cords?
A. pharynx
B. larynx
C. trachea
D. bronchi
The part of the upper respiratory system known as the vocal cords is located in the larynx. The correct option is B.
The larynx, commonly referred to as the voice box, is situated between the pharynx (throat) and the trachea (windpipe).
The vocal cords are two folds of mucous membranes within the larynx that vibrate to produce sound when air passes over them, enabling speech and vocalization.
It serves multiple functions, including the production of sound for speech and protecting the airway during swallowing.
The vocal cords are composed of delicate muscle tissue covered by a layer of mucous membrane.
They are positioned horizontally within the larynx, stretching from the front to the back.
When at rest or during normal breathing, the vocal cords are open, allowing air to pass freely through the larynx and into the lungs.
During speech or vocalization, the muscles surrounding the vocal cords tighten, bringing the vocal cords closer together.
As air from the lungs passes through the narrowed gap between the vocal cords, they vibrate rapidly.
These vibrations produce sound waves, which then resonate in the pharynx, mouth, and nasal cavity, allowing us to form words and communicate.
Thus, the correct option is B.

C. material for repair
d. answer not given
Answer:
A quick energy
Explanation:
Most of the cells in your body use glucose along with amino acids (the building blocks of protein) and fats for energy. But it's the main source of fuel for your brain.
Consider a food web in which snakes eat mice; toads eat beetles; owls eat mice and toads; eagles eat rabbits, snakes, and owls; cougars eat deer; and foxes eat rabbits and mice. What animal occupies (gets energy in) more than one trophic level
The animal that takes energy from more than one trophic level is eagle due to eating of many organisms.
Which animal gets energy in more than one trophic level?The eagle is the animal that takes energy from more than one trophic level in the given food web because in this food web eagle feeds on animals such as rabbit, reptile such as snake and bird such as owls.
So we can conclude that the animal that takes energy from more than one trophic level is eagle.

In this case, the owls and eagles are two animals that occupy more than one trophic level in the food web.
What is a trophic level?A trophic level is a specific position in the food web that one population and/or organism occupies in the ecosystem.
An organism can have different roles in an ecosystem and thus occupy more than one trophic level.
Organisms in the first trophic level are called producers, whereas primary consumers are located in the second level.

If you wanted to see a cell wall, where could you look?.
Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.

How does a successful immigration rate impact the biodiversity of an island?
Answer:
as the number of species present increases, the immigration rate decreases
Explanation:
According to ETIB, the number of species present on an island is determined by a balance between immigration and extinction. Generally, as the number of species present increases, the immigration rate decreases and the extinction rate increases.
A successful immigration rate impact the biodiversity of an island in several ways.
How does a successful immigration rate impact the biodiversity of an island ?By the studies of several scientists, the number of species present on an island is determined by a balance between immigration rate and extinction rate. Generally, as the number of species present increases, the immigration rate increases and the extinction rate decreases. Therefore a successful immigration rate provides the animals and birds to migrate from different parts of the world and settle down in a particular island. Therefore for a greater amount of immigration rate, the biodiversity of the island is maintained in a good order. Therefore for a good immigration rate, the biodiversity of a land is largely increased.
