Answer:
Higher
Explanation:
Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.
Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.
In order for oxygen to leave the alveoli and enter the blood, there would be a higher concentration of oxygen in the alveoli compared to the blood.
Diffusion is the process by which compounds or substances move from a
region of higher concentration to that of a lower concentration. This helps to create an equilibrium in the concentration of the substance to prevent cell death due to shrinking etc,
The alveoli is found in the lungs which is the organ of respiration and the
oxygen present is usually in higher concentration and moves to regions of
low concentration in the blood.

Why do third level consumers gain was energy from their food
Answer: Why do third level consumers gain was energy from their food?
Explanation: It rarely happens, so often the tertiary consumers do not get eaten. Also, as tertiary consumers eat the primary and secondary consumers, they receive 10% of their energy from the producers. ... There are few omnivores/third-level consumers, because most third-level consumers eat only meat, since it's very tasty to them.

During which two months do both the Northern and Southern Hemispheres receive the same amount of energy from the Sun? December and June January and July March and September May and November
Answer:
Answer C
Explanation:
The answer is March and September
Both Northern and Southern Hemispheres receive the same amount of energy from the sun in March and September
EquinoxesIt is a phenomenon that is used to describe a period during which both the Southern and Northern Hemispheres receive the same amount of energy from the sun.
During this period, the declination of the sun is at the equator. thus, both sides of the Hemisphere receive an equal proportion of the sun both in duration and energy magnitude.
Equinoxes occur twice in a year - March and September

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the cell. What is the best explanation for this observation?
a) the cell has just gone through the S –phase of the cell cycle so there is double the amount of DNA
b) the cell has just gone through telophase but not cytokinesis
c) the cell has gone through meiosis I and is preparing for meiosis II
d) the cell is in G1 and is preparing for DNA synthesis
Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
Chromatids, which are chromosomes, are found in the cell poles. It initiates the formation of the nucleus membrane. The chromosomes begin to turn into chromatin. Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.
c. A somatic cell does not experience meiosis.

Which equation best represents the aerobic respiration reaction?
The chemical equation which best represent an aerobic respiration reaction is: D. Glucose + Oxygen -----> Carbon Dioxide + Water + ATP.
An aerobic reaction can be defined as both biological and chemical processes that generally takes place in the presence of oxygen.
This ultimately implies that, an aerobic reaction requires oxygen before it can occur.
On a related note, an aerobic respiration reaction refers to how the body of a living organism uses oxygen such as;
Running. Swimming. Walking. Jogging.Basically, the two main reactants (inputs) reactants for an aerobic respiration reaction include:
Glucose.Oxygen.Conversely, the end products of an aerobic respiration reaction are:
Carbon dioxide.Water.ATP.In conclusion, the chemical equation which best represent an aerobic respiration reaction is:
[tex]Glucose + Oxygen ---> Carbon \;Dioxide + Water + ATP[/tex]

The equation that best represents the aerobic respiration reaction is: Glucose+ oxygen→ Carbon Dioxide+ Water+ ATP.
In this equation, glucose (C6H12O6) is oxidized in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy. This is the process of aerobic respiration, which occurs in the mitochondria of cells to generate energy for cellular activities.
Vigorous breath is the organic cycle where food glucose is changed over into energy within the sight of oxygen. The majority of mammals, birds, humans, and plants use this kind of respiration.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?
Answer:
This question is incomplete but the completed question is below
eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?
(a)The roots change into branches, and the branches turn into roots.
(b)The roots grow toward the force of gravity, and the shoots grow away.
(c)The plant will become a smaller version of a mature plant.
(d)Roots always grow toward the dark, and shoots grow toward the light.
Two options appear to be correct here: options B and D
Explanation:
Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b

Answer:
Tertiary level
Explanation:
Which factor increases as a result of increasing altitude? air pressure, air density, height of sea level or space between gas molecules
Answer:
space between gas molecules
Explanation:
as the altitude increases the air density decrease because of weaker gravity and these led to more distant of air molecule and the space between gas is increased
As the altitude increases the air density decrease because of weaker gravity and these led to more distance between air molecule and the space between gas is increased.
The answer is option D.
What is the effect of the increase in height?As the height increases, the pressure increases. - As the height increases, the air density increases. - Air pressure and congestion are very low at sea level. - Heavy air is more pressurized than small dense air.
Why does the pressure rise at higher altitudes?The gravitational pull between the earth and the air atoms is much larger than those distant molecules - they are heavier - pull them closer and increase the force (energy per unit) between them.

c) true
d) false
e) false
Explanation:
hi im taking ap biology and it's not my best subject but here r my reasonings:
a) inhibitors decrease the rate of reactions in general, so i would assume that increasing the number of inhibitors would decrease the overall rate or reaction
b) it's false bc allosteric inhibitors bind to a place on the enzyme other than the active site. u can see on the figures that the blue-green allosteric inhibitor is in a place other than the active site at the top
c) because allosteric inhibitors bind to a different place on the enzyme, this often results in an formational change in the enzyme. bc of this change in shape of the enzyme, this can rly prevent the substrate from binding to the active site
d) i dont think adding a competitive inhibitor will increase the number of products bc competitive inhibitors decrease the reaction rate by blocking substrates from binding to the active site :/
e) false bc competitive inhibitors do not bind to the substrates; they bind to the active sites, thus blocking the substrate from entering the active site. u can see this in the blue-green square at the top figures
