Answer:
The correct answer would be in this case C) respiratory system. It is the main source where the process of gas exchange occurs, taking in oxygen and breathing out carbon dioxide into the rest of our surrounding environment.
The respiratory system is responsible for the exchange of gases with the atmosphere. So the correct option is C.
What is the respiratory system?
The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with inhalation and exhalation, it:
Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.Shields your airways from irritants and dangerous chemicals.
Therefore the correct option is C.

What gases was not present in earths earth atmosphere
Answer:
Primitive Earth (Before life) contained no or very little Oxygen (element#8)
According to scientific theory:
Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.

the difference between Eukaryotic and prokaryotic cells
Answer:
Eukaryotic cells are cells with a nucleus (such as animal and plant cells) whereas Prokaryotic cells are cells without a nucleus (such as a bacterium cell)
Explanation:
Where in a cell would you most likely find DNA?
Your answer is → compartment within the cell called a nucleus
In a cell, DNA would most likely be found inside the nucleus which is known as the controlling center of the cell.
What is DNA?DNA stands for Deoxyribonucleic acid. It is considered the most common genetic material of living organisms. The genetic information of a particular organism is encoded with these segments, known as DNA.
The process of transcription is initiated within the nucleus of the cell which transforms DNA into mRNA. It is known as the brain of the cell. Due to compartmentalization in eukaryotic organisms, a well-defined nucleus has appeared which helps in the transfer of genetic information from one generation to the next.
Therefore, the nucleus is the region where DNA is most likely found within the cell.

Answer:
Velocity
Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.

Which Change over time in Landsat maps would most likely be associate with contaminated water habitats nearby?
A. increased size of dark green areas
B. increased size of gray areas
C. green areas replaced with yellow areas
D. Gray areas replace with light green areas
Answer:
The answer would be B,
Explanation:
Increased size of gray areas is the change over time in the landsat maps that would most likely be associated with the contaminated water habitats nearby. Thus, the correct option is B.
What are Landsat maps?
Landsat is a moderate spatial-resolution imagery which provides the large areas of repeated data coverage at a scale that enables the users to see the detailed human-scale processes, such as urbanization, but not the individual houses.
The Landsat series of Earth Observation satellites have continuously acquired images of the Earth's land surface, which provides uninterrupted data to help the land managers and policymakers to make informed decisions about the natural resources and the environment. The increase in the gray areas in the landsat maps is associated with the water contamination.
Therefore, the correct option is B.

Which characteristic best explains why lentic ecosystems are more responsive to seasonal changes than lotic ecosystems?
Photosynthetic organisms keep lentic ecosystems warmer during the winter season.
Lentic ecosystems are susceptible to temperature due to their low dissolved oxygen.
Lotic ecosystems have low nutrient levels, making them more sensitive to temperature.
Lentic ecosystems tend to have smaller volumes of water compared to lotic ecosystems.
Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.
Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.
Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.
The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.
Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.
