¿Cuáles de las siguientes características permite el intercambio gaseoso entre el Oxígeno (O2) y Dióxido de carbono (CO2) en los alveolos?
Answer:
Difusión y afinidad de la hemoglobina.
Explicación:
La difusión y afinidad de la hemoglobina son las características que permiten el intercambio gaseoso entre el Oxígeno (O2) y el Dióxido de Carbono (CO2) en los alvéolos. Debido a la difusión, las células de hemoglobina descargan o eliminan el gas de dióxido de carbono que es más alto en la hemoglobina en comparación con los alvéolos, por lo que el dióxido de carbono se mueve de la hemoglobina a los alvéolos mientras que, por otro lado, el oxígeno se mueve dentro de la célula de hemoglobina a través de la difusión y la estructura de la hemoglobina atraer y adherir moléculas de oxígeno consigo mismo.

During a baseball game, a hitter strikes the ball with a bat. When this happens, the ball and the bat exert a
force on each other. Why does the ball accelerate away from the bat more than the bat accelerates away from
the ball?
Answer:
The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball

Put the following in order from smallest to largest.
- protein
- eukaryotic cell (has nucleus)
- virus (NOT alive)
- prokaryote (bacteria, no nucleus)
Answer:
Protein → virus → prokaryotic cell → eukaryotic cell
Explanation:
This question is asking to place the following components of organisms in an ascending order of magnitude i.e. from smallest to largest.
- Proteins are macromolecules that are found in living cells where they serve different functions. Since they are found inside cells, they are the smallest on this list.
- Viruses are microorganisms considered to be non-living because they do not show characteristics of living things. Viruses are pathogenic organisms that attack living cells. They are the smallest microbes found having sizes in nanometers (nm).
- Prokaryotes are group of organisms with no nucleus e.g bacteria. They possess cells that are smaller than that of eukaryotes.
- Eukaryotic cells i.e. cells with nucleus, have the biggest size of any cell. Hence, they are the largest in the list.
Based on the above description, the ascending order of magnitude is as follows: Protein → virus → prokaryotic cell → eukaryotic cell

9. If you conducted the analysis portion of Experiment 2, you calculated
the rate at which the percentage of fish with a complete pelvis
decreased in that ancient lake. Do you think the same rate of change
would apply to modern fish populations?
A. Probably not, since the environment has changed so much in the 10
million years since that ancient lake existed.
B. Although we did not measure this directly, it is possible that the same
rate of change observed in the fossil record applies to modern
populations.
C. The fossil record analyzed in Experiment 2 only spans 15,000 years,
so we cannot draw any conclusions to modern populations, which
evolved over a much longer period of time, at least 10,000 years.
D. The rate of evolution of a particular phenotype cannot be calculated
from the fossil record because the fossil record is always fragmentary.
Answer: Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern populations.
Explanation:
Hi. You didn't give the experiment and I searched online but couldn't find the experiment but through further researches, I got to know that the correct option is B "Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern population"
Therefore, the correct option is B.

cones help with color distinction
Answer:
CONES HELP WITH COLOR DISTINCTION
Explanation:
Cone cells, or cones, are one of the two types of photoreceptor cells that are in the retina of the eye which are responsible for color vision as well as eye color sensitivity; they function best in relatively bright light, as opposed to rod cells that work better in dim light.

Which population eats kelp the most?
Answer:
bristle worms
Explanation:
In kelp forests, the most commonly found invertebrates are bristle worms, scud, prawn, snails, and brittle stars. These animals feed on the holdfasts that keep kelp anchored to the bottom of the ocean and algae that are abundant in kelp forests. Sea urchins will often completely remove kelp plants by eating through their holdfasts. Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish.
