Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.
Explanation:
According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.
The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:
1. The chloroplast and mitochondria have circular DNA like bacteria.
2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.
Answer: Geologists must look closely at the physical properties of a mineral. These properties can include: color, streak, hardness, cleavage, specific gravity, crystal form, and others.
Explanation:
Answer:
The correct answer is - incomplete dominance.
Explanation:
A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.
In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.
Thus, it is the case of incomplete dominance.
