Which of the following phenotypic classes reflect offspring that were generated as a result of a recombination event?
babymother [125]

Answer:

The correct options are: A " vestigial wings, red eyes" and D "full wings, purple eyes"

Explanation:

female parent: vg+pr+/vg pr

(phenotype - full winged and red eyes)

male parent:  vgpr/vgpr

(phenotype - vestigial winged and purple eyes)

Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.

Describe how amoebas obtain food?
monitta
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
