Answer:
The respiratory system has cells that produce MOCO OR MUCUS, which trap germs and dust. On their surface they have a large number of cellular structures called CILIAS, whose function is to spread mucus and direct it outwards. In the stomach, the digestive glands produce the STOMACH ACID, which, due to its extreme ACIDITY, attacks and destroys the PATHOGEN MICROORGANISMS that are introduced with food and drink.
Explanation:
In the respiratory and digestive apparatus there are two types of super specialized mucous upholstery, where the cellular world is challenged.
In the respiratory mucosa the production of mucus and the mobilization of the cilia are part of the innate response of the organism as well as the acidity that is generated in the upholstery and in the gastric tract.
Answer:
The new life form will come in domain of bacteria.
Explanation
:
As we know that there are certain characteristic of bacterial cells which are listed below.
Composition of cell wall
:
Cell wall of bacteria is composed of carbohydrates protein complex known as peptidoglycan
.
Presence of organelles
:
Bacterial cells lack all organelles except ribosomes
Presence of fatty acids in plasma membrane
The plasma membrane of bacterial cell is composed of a lipid bilayer made up of phospholipid. It contains fatty acids
Conclusion
In microscopic studies of new organism all the characteristics features of bacteria have been found. So, this new life form belong to bacteria.
Metamorphic rocks need he and pressure to form
Answer:
B. the direction of the wind at the time it was deposited
Explanation:
Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
The question is incomplete, the complete question is;
Maria collected the gas given off by a glowing piece of charcoal. The Gas was then bubbled through a small amount of colorless limewater. Part of Maria's report stated, "After the gas was put into the jar, the limewater gradually changed to a milky white color." This statement is
An observation
A conclusion
A generalization
A hypothesis
Answer:
An observation
Explanation:
The statement; "After the gas was put into the jar, the limewater gradually changed to a milky white color." is an observation.
A observation rs to any event that occurs immediately after a particular chemical/ physical test is performed.
In this case, the test is that the gas was put into a jar containing limewater and an observation was made immediately
