During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Pr
myrzilka [38]

Answer: Exponential

Explanation:

The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.

This is what happened with humans during the Neolithic Revolution when we began farming.

The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.

The classical point of view is that, during mitochondrial respiration, three ATP molecules can be generated from one molecule of
Stells [14]

Answer:

38

Explanation:

In eukaryotic cells, the maximum production of ATP molecules generated per glucose molecule during cellular respiration is 38, i.e., 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 34 ATP molecules from the Electron Transport Chain (ETC). <em>In vivo</em> (i.e., in the cell), this number is not reached because there is an energy cost associated with the movement of pyruvate (CH3COCOO−) and adenosine diphosphate (ADP) into the mitochondrial matrix, thereby the predicted yield is approximately 30 ATP molecules per glucose molecule. In aerobic bacteria, aerobic respiration of glucose occurs in the cytoplasm (since bacteria do not contain membrane-bound organelles such as mitochondria), and thereby, in this case, it is expected that aerobic respiration using glucose yields 38 ATP per glucose molecule.

Di a que tipo de órganos pertenecen las siguientes estructuras. Justifica tu respuesta:
Aleonysh [2.5K]

Answer:

La pata de un pato y la aleta de un pez son en ambos casos son elementos que les permiten tanto al pato como al pez moverse, además de sus funciones de estabilidad. La aleta de una ballena y el brazo del ser humano, sucede lo mismo que en el caso anterior. En el caso de la aleta de la ballena, es como la aleta del pez. En cuanto al brazo del ser humano permite realizar movimientos que contribuyen al desarrollo de sus funciones, como por ejemplo, agarrar distintos elementos. La pelvis reducida de los cetáceos no tiene actualmente ninguna función.

Explanation:

La pata de un pato es una extremidad que por su estructura le permita nadar perfectamente. En cuanto a la aleta de los peces y ballenas, es una parte de estos animales formada por tejido conjuntivo. Pueden tener distintos tamaños y su principal función no sólo es permitir el movimiento sino también la estabilidad. En cuanto a la pelvis reducida de los cetáceos era algo que tenía sentido en especies de antaño. Durante la evolución, su utilidad de fue perdiendo, como podría mencionarse el ejemplo en los humanos de las muelas de juicio.
