When you sneeze, air is forcefully exhaled from your nose. As the air exits the nose, what is the last structure the air will pa

inn [45]

The last structure the air will pass through will be External nares

Explanation:

The upper portion of the respiratory tract is the nasal cavity and the nose. The external nose forms the first and foremost respiratory tract area. Nose is the major part that is responsible in exchanging air with the atmosphere. It is responsible for the human survival.

There are two openings in a nose. These are called as nostrils. They are also called as exterior nares. The air from the atmosphere when inhaled it enters into the nostril. from there is is sent to the nasal cavity. Nasal cavity is the place where the air that is inhaled will be purified and it is transported to various human parts. thus, when air contains any dust or impurities it will make you to sneeze thereby the air gets out of the nose through External nares

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first

jek_recluse [69]

Answer:

D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.

Explanation:

Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.

However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.

Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
