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).
You should reask this question and put a picture so that we can understand it better :)
Same phenotype but different genotype is possible due to presence of dominant allele. A dominant allele , when present in genotype, always expresses itself: both in double dose and in single dose.
Answer:
The composition of a planet's atmosphere also influences its temperature, particularly the concentration of greenhouse gases present. The Earth converts solar radiation in the visible spectrum to infrared radiation, which it emits; greenhouse gases absorb infrared radiation and warm the atmosphere.
Explanation:
B ecosystem. They include abiotic factors and biotic factors.
