En un bosque oscuro, ¿qué variación de la polilla salpicada se reproduciría en
mayor número? En este escenario, la variación
de la polilla moteada
se reproduciría en mayor número debido a.
Answer:
Condiciones ambientales adecuadas.
Explicación:
La variación de la polilla moteada se reproduciría en mayor número debido a las condiciones ambientales adecuadas. El color oscuro del bosque ayuda a la polilla moteada a esconderse de sus depredadores que se alimentan de ellos y provoca la disminución de la población de polillas. Es un proceso de selección natural en el que la polilla de color oscuro sobrevive y aumenta la población debido al color oscuro del bosque, mientras que la población de polilla de color claro disminuye debido a la alta depredación.

The fifth grade craft club is making aprone to sell
Each apron take 1.25 yards of fabrie that costs $3
per yard and 4.5 yards of trim that costs $2 per yard,
What does it cost the club to make one apren? If the
club wants to make $1.75 profit on each apron how
much should they charge per apron?
Answer:
Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
Explanation:
Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:
1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard
1.25 x 3 + 4.5 x 2 = X
3.75 + 9 = X
12.75 = X
12.75 + 1.75 = 14.50
Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.

describe each step of endocytosis
Explanation:
The Basic Steps of Endocytosis
The plasma membrane folds inward (invaginates) forming a cavity that fills with extracellular fluid, dissolved molecules, food particles, foreign matter, pathogens, or other substances.
The plasma membrane folds back on itself until the ends of the in-folded membrane meet. This traps the fluid inside the vesicle. In some cells, long channels also form extending from the membrane deep into the cytoplasm.
The vesicle is pinched off from the membrane as the ends of the in-folded membrane fuse together. The internalized vesicle is then processed by the cell.
