A population of 20 monarch butterflies colonizes a meadow. The meadow's carrying capacity for monarch butterflies is 5,000 indiv
kotegsom [21]

Situation explanation:

So, the maximum capacity of monarch butterfly individuals that can live in the meadow is 5000. That means that the 20-butterfly population will continue growing (reproducing) until it reaches 5000.

Answer explanation:

If the population were to grow exponentially, there wouldn't be an end and the 5000-limit would not be respected.

If the population were to grow logistically, the end of the growth would be the same as the limit, which means that the 5000-limit would be respected.

--> Therefore, the only possible answer is D, which states that the population will reach 5000 and after that the growth will stabilise (exactly what would hapen in a logistic growth).

Hope it helped,

Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when th
geniusboy [140]

Answer:

Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.

Explanation:

Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.

Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.
