What similarities and differences do prokaryotes have with modern day green plants

2 answers:

8 0

For similarities for modersnoa green plant cells and prokaryote cells we have topics such as: presence of genetic material in both (DNA), presence of RNA (ribonucleic acid), presence of ribosomes (protein producers), presence of cell wall and presence of a matrix fluid that is called a cytoplasm.

For differences between these two cell types we have: prokaryotic cells do not have the so-called library, a membrane that holds genetic material separate from the cytoplasm. That is, while in a prokaryote cell the genetic material is found in the cytoplasm, in the cells of modern green plants the genetic material is found in an organized nucleus. Prokaryotic cells also lack some organelles such as mitochondria and the Golgi complex, while plant cells do. Moreover, there is a difference in the cell wall composition of these cells, in prokaryotes the cell wall is composed of peptidoglycan and in plant cells it is composed of cellulose.

How can using a combination of policy tools be more efficient than using one exclusively?

8090 [49]

<h3>Answer:</h3>

c. Using a combination of policy tools prevents the use of mandatory policies.

<h3>Explanation:</h3>

Regulating and controlling behavior is crucial for authorities. Authorities employ a number of tools such as enactment, penalties, laws, taxes, and support in order to change behavior in the concern of the people. The rising amount of policy difficulties has produced a difficulty for governments to control action. Moreover, conventional tools and methods in executing policy may be insufficient and ineffectual in circumstances of our current situation.

What are the four important conditions of a respiratory surface

Ksivusya [100]

The four important characteristics of respiratory surface are:

1. Thin walls

2. Moisture

3. Large surface area

4. Blood supply

Respiratory system or respiratory tract is divided into upper and lower tract. Upper respiratory tract includes nose and its cavities, sinuses, pharynx and the part of the larynx. Lower respiratory tract consists of the trachea, bronchi, bronchioles and the alveoli.

Alveoli are the ends of the respiratory tract the smallest units in it. Alveoli are small folded air sacs that are branching off from alveolar ducts and providing an extremely large surface area for the gas exchange. Gas exchange occurs thanks to small blood vessels – capillaries that surround alveoli and it occurs via the process of diffusion.

So, respiratory surface is thin membrane also known as the blood–air barrier that consists of the alveolar epithelial cells, their basement membranes and the endothelial cells of the alveolar capillaries.
