Answer:
Upper-layer skin cells, the cells in the front surface of the eyes
Explanation:
Here is what I found....hope this helps and i'm still trying to wake up XDD
Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body. Fortunately, we have lungs that can actively pull in oxygen and transfer it to the blood, allowing the body to transport oxygen to the cells by using the blood like a fleet of delivery trucks. Most of our cells rely on the blood delivery service. However, the cells in the outer layers or our skin and eyes are in direct contact with the atmosphere and can efficiently get their oxygen right from the air.
If samples of silver and lead each had volumes equal to 1 cm3, which sample would have the greater mass? What would the difference in the masses be?
The answer would be lead.
Explanation: Lead has a higher density than silver.
In the absence of oxygen, the cell's ability to convert the stored energy of glucose to usable ATP
In the absence of oxygen, the cell's ability to convert the stored energy of glucose to usable ATP is greatly decreased. Thus, the correct option is C.
What is Cellular respiration?Cellular respiration is the process through which the biological fuels are oxidized in the presence of an inorganic electron acceptor such as the oxygen atom to produce large amounts of energy, to drive the bulk production of ATP (adenosine triphosphate) in the mitochondria.
The purpose of cellular respiration is to provide the body cells with the energy which they need to function. If living things could not get the energy which they need out of food, it would be absolutely worthless for them. All living things would eventually die, no matter what the quality and amount of food.
Therefore, the correct option is C.

Scientists discovered similar fossils in rock masses on continents located both sides of the Atlantic Ocean.How does this discovery provide evidence supporting the theory plate of tectonics?
Explanation:
Because these fossils would have had no way to get across the ocean, especially for large terrestrial animals. The continents used to be in different locations, allowing some animals to cross. These animals then died on different continents as they shifted, thereby proving that the continents used to be much closer than they are now.
The theory of evolution by natural selection means that what is changing over time?
Answer:
Ancient Organisms evolving into what we have now
Explanation:
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring.

Analyze the graph below and identify the points where the population is stable at the carrying capacity.
Answer:
To find carrying capacity on a graph, you need to locate the point on the graph where the population line is horizontal. Alternatively, the carrying capacity may be explicitly marked with a dotted horizontal line or a horizontal line of a different color.
Explanation:
i dont know if this is right but hope this helps
The carrying capacity on a population growth graph is the level at which the population stabilises and achieves equilibrium as a result of the environment's resources.
What is the reason for the equilibrium ?This equilibrium happens as a result of the population curve plateauing as the limiting elements, such as food, water, and space, start to restrict the population's ability to grow.
The carrying capacity is symbolised graphically by a horizontal line on the graph, signifying that the population has reached its limit and cannot grow any further.
This horizontal line can be clearly identified on the graph by a dotted line or a different colour. Alternatively, the population line's horizontal intersection with the point where it stops growing can be used to determine the carrying capacity.
A constant condition of population has been reached.
It is crucial to remember that a population's carrying capacity can alter over time owing to a variety of variables, such as changes in the climate or improvements in technology that make resources more accessible.

why can only massive stars form black holes ? ( describe )
the natural consequence of the evolution of massive stars. Neutron stars have an upper mass limit of 2 to 3 solar masses. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole.
The inevitable result of the development of enormous stars. The maximum mass of neutron stars is 2 to 3 solar masses. A more massive collapsed item will keep collapsing forever, eventually creating a black hole.
What is a Black hole?Space-based black holes are regions of extreme density that produce large gravity wells. Even light cannot escape the strong pull of a black hole's gravity once it reaches a specific area. And in a theorized process fittingly known as spaghettification, anything that gets too close, be it a star, planet, or spaceship, will be stretched and squished like putty.
According to the question, A supernova is a star that explodes brightly when it is dying. A supernova can happen when a star loses heat at its core, causing it to eventually collapse. This kind of supernova results from the death of huge stars. They take place in galaxies with active star formation and an abandoned black hole or neutron star.
Supernovae can also happen when one star collides with another as it orbits another. In a white dwarf, this happens. This can happen in a very old star cluster, which is a component of a binary system and leaves no compact object in its wake.
