Answer:
The respiratory system is directly connected to the external environment. More specifically, the gaseous environment around me can automatically find its way into the internal environment inside me.
The human respiratory system takes in air from the external environment. The purer the air is, the purer the content of its intake.
The system which keeps the lungs clean is found in the trachea which is lined with cells containing hair-like protrusions called cilia and also produces mucus and water droplets. The mucus and the cilia's activities combine to keep air passages hydrated and work together to trap dust, bacteria, and other foreign substances. An example of a foreign substance is heavy smoke from a building on fire. Other examples are cigarette smoke, heavy atmospheric dust such as is found in deserts. When these substances are inhaled, they can temporarily impede the efficiency of the cilia.
So it is important for one to avoid environments whose air is contaminated.
Because a contaminated environment translates to an impeded functioning of the respiratory system and a reduction in the quality of oxygen that reaches the bloodstream.

Cell theory teaches us that cells are the ?
Answer:
in biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
There is no universally accepted definition of life. Some biologists consider non-cellular entities such as viruses living organisms,[1] and thus reasonably disagree with the first tenet

What do plants need to survive? How do plants obtain energy?
Answer: obtain energy
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

PLEASE HELP 50 POINTS. In Newton's cannonball illustration, what happens if the cannon ball's velocity is slightly faster than the circular orbit speed?
A. the cannon ball will crash into space B. the cannon ball will break orbit and go off into space. C. The cannon ball will have an elliptical orbit
The option that happens if the cannon ball's velocity is slightly faster than the circular orbit speed is option C: The cannon ball will have an elliptical orbit.
What is the Newton's cannonball illustration about?The Newton's cannonball illustration states that when a given ball is said to have gone or travels a little more faster than that of the circular velocity, it will create a kind of an elliptical orbit with the cannon and this is done at the perigee which is said to be the closest point in the orbit.
Note also that If the ball is said to have travels at the escape velocity, the orbit will be tend to open.
Therefore, The option that happens if the cannon ball's velocity is slightly faster than the circular orbit speed is option C: The cannon ball will have an elliptical orbit is correct.

Life is a dynamic process, and living things are always at work synthesizing new molecules. Because proteins carry out so many of the essential functions of living things, including the synthesis of other macromolecules such as lipids and carbohydrates, a big part
of the cell is devoted to their production and distribution.
Which cell organelle is involved in the synthesis of proteins?
A.) Smooth endoplasmic reticulum
B.) Lysosomes
C.) Rough endoplasmic reticulum
D.)Mitochondria

what cellular process is occurring in the organelle labeled B?
Answer:
B. Cellular respiration
Explanation:
The cellular process that is occurring in the organelle labeled B is "Cellular respiration".
From the image, the organelle B is Mitochondria. Cellular respiration takes in the mitochondria and this is important because it leads in the production of ATP using the chemical energy that is found in glucose and other nutrients.
Mitochondria are known to be membrane-bound organelles. Their function is to generate most of the chemical energy that the cell needs for biochemical reactions.
What type of system is required to maintain the amount of sugar in the blood at a certain
level, making sure it does not rise too high or fall too low?
Answer:
The Digestive system.

The chart shows the percentages of different groups of animals that are at risk of extinction. Endangered (%) Threatened (%) Birds 9.5 4.0 Reptiles and amphibians 12.0 3.5 Fish 14.1 7.6 Mollusks 24.0 4.0 Which claim is supported by the evidence in the chart? Fewer than ten bird species are endangered. More birds are at risk than reptiles. There are more mollusks at risk today than at any time in history. More fish are endangered than are threatened.
Answer:
More fish are endangered than are threatened.
Explanation:
This question includes a chart that describes the risk level (in percentage) of certain organisms. The comprehensive summary of this chart is as follows:
Endangered
(%)
Threatened
(%)
Birds
9.5
4.0
Reptiles and amphibians
12.0
3.5
Fish
14.1
7.6
Mollusks
24.0
4.0
Based on this chart, it can be observed that the level of endangered fish species is 14.1% while the level of threatened fish species is 7.6%. Hence, more fish are endangered (14.1%) than are threatened (7.6%).

Inversion is a type of mutation that
Answer:
the action of inverting something or the state of being inverted.
Explanation:
This type of mutation occurs a piece of DNA detaches from a chromosome during the reproductive stage and then reattaches to the chromosome in a reversed order. This will change the genetic code and make it very difficult to read.
Explain the relationship between DNA, genes and proteins and mutations.
Answer:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation

1. Why would cells in some organs be consuming more oxygen than cells in other organs?
Answer:
Answer is below:
Explanation:
As oxygen molecules diffuse into the cell, they are consumed. But interstitial fluid volume is only a little more than half the intracellular fluid volume. The circulating blood must be brought close to the cells since the systemic organs (tissues) are connected in parallel.
