Answer;

Yes

Explanation;

-Yes it is possible that a structure as complex as an image-forming eye evolved by natural selection. if the photoreceptor cells and simple eyes that preceded it were useful to the animals in which they arose. Additionally, such photoreceptors and simple eyes can be seen in many living animals.

-According to scientists; the simple light-sensitive spot on the skin of some ancestors gave it some tiny survival advantage. Random changes then created a depression in the light-sensitive patch, a deepening pit that made "vision" a little sharper and also the pit's opening gradually narrowed, so light entered through a small aperture. Then the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the human eye and over time a lens formed at the front of the eye.

Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. this is called?
Igoryamba

Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.

Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.

Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.

Match the following. 1. the basic building block of all forms of life resolving power 2. the idea of Schleiden and Schwann that
Roman55 [17]

Answer:

1. Cell

2. cell theory

3. Organismal theory

4. resolving power

Explanation:

The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).

2. Cell theory was formulated and developed  by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.

It states:

1. Living organisms are made up of cells.

2. Cells are the basic unit of life.

3. Cells are formed from pre-existing cells.

4. Energy flows inside the cell.

5. DNA is passed on from cell to cell.

6. All cells have the same basic chemical composition.

3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.

4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
