How does the air pressure at sea level compare with air pressure at higher elevations such as
Mt. Everest. In your explanation include information about the number of air molecules in a
parcel of air at that altitude and the affect of gravity on pressure at both altitudes.
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

tissue respiration, location in the cell and sequence of reaction
Answer:
The Location of Cellular Respiration
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.
Tissue respiration occurs internally where the oxygen carried by the blood and RBCs is exchanged with the carbon dioxide produced by the cells of various tissues. ( This answers the location of where tissue respiration occurs
Sequence of tissue respirationThe stages of tissue respiration include:glycolysis - pyruvate oxidation - citric acid or Krebs cycle - oxidative phosphorylation.
Cell tissue respiration
It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water
Cellular tissue respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

Which two statements best describe jet streams in the northern hemisphere?
A. The subtropical jet stream separates warmer air near the equator

B. The polar jet stream separates colder air near the pole and
warmer air to the south.
C. The subtropical jet stream causes ocean currents to form near
the equator.
A
D. The polar jet stream circulates air between the North Pole and the
South Pole.
SUBMIT
The correct answer is B. In the Northern Hemisphere, the polar jet stream separates colder air near the pole and warmer air to the south.
The jet stream is a geophysical effect caused by the large temperature difference between the north pole and the equator. Something similar also happens on a small scale. In summer, when night falls and the ground cools where the sun is gone, air blows from north to south across the boundary between warm and cold air. This is the refreshing evening breeze.
From the north, a jet stream generally supplies colder air than from the west or south. The jet stream also creates depressions with a warm front and a cold front.

Which type of effort to preserve species do you
think is most worthwhile?
One of the most effective and worthwhile methods of species preservation is the preservation and protection of wildlife habitats.
What is a habitat?In the most simple of terms, a habitat is a section of terrain in which certain organisms live. Habitats can range from deserts to rainforests and everything in between.How protecting them can be important.The protection of habitats is of utmost importance. The leading cause of species extinction is habitat loss due to human activities such as city expansions or the collection of raw materials for industrial use. Protecting species habitats will allow the species in question to not only survive but also thrive and reproduce, thus leading to a safe population number and avoiding extinction.Therefore, we can confirm that one of the most effective and worthwhile methods of species preservation is the preservation and protection of wildlife habitats to allow the species that live in them to thrive.

Explanation:
All living things have internal that helps them carry out basic functions.
true
................................
Answer:
True
Explanation:
By the end of grade 2. All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive, grow, and produce more plants.
By the end of grade 5. Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. (Boundary: Stress at this grade level is on understanding the macroscale systems and their function, not microscopic processes.)
By the end of grade 8. All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). Unicellular organisms (microorganisms), like multicellular organisms, need food, water, a way to dispose of waste, and an environment in which they can live.
Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues or organs that are specialized for particular body functions. (Boundary: At this grade level, only a few major cell structures should be introduced.)
By the end of grade 12. Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Outside that range (e.g., at a too high or too low external temperature, with too little food or water available), the organism cannot survive. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.
A central feature of life is that organisms grow, reproduce, and die. They have characteristic structures (anatomy and morphology), functions (molecular-scale processes to organism-level physiology), and behaviors (neurobiology and, for some animal species, psychology). Organisms and their parts are made of cells, which are the structural units of life and which themselves have molecular substructures that support their functioning. Organisms range in composition from a single cell (unicellular microorganisms) to multi-cellular organisms, in which different groups of large numbers of cells work together to form systems of tissues and organs (e.g., circulatory, respiratory, nervous, musculoskeletal), that are specialized for particular functions.
Special structures within cells are also responsible for specific cellular functions. The essential functions of a cell involve chemical reactions between many types of molecules, including water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information, in the form of DNA. Genes are specific regions within the extremely large DNA molecules that form the chromosomes. Genes contain the instructions that code for the formation of molecules called proteins, which carry out most of the work of cells to perform the essential functions of life. That is, proteins provide structural components, serve as signaling devices, regulate cell activities, and determine the performance of cells through their enzymatic actions.
