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.
The correct answer is D. Both A and C
Explanation:
In biology, a phenotype refers to a trait or characteristic that is observable in an organism, including physical characteristics, physiological characteristics, and behavioral characteristics. The phenotype is the result of the expression of genes or environmental factors. Considering this, both "a certain duck has a blue beak" and "most cheetahs live solitary lives" are phenotypes because they are traits that can be observed in terms of morphology or physical characteristics in the case of the duck or in terms of behavior in the case of the cheetah. On the other hand, a mutation is not necessarily a phenotype except if it is expressed.
THE STRUCTURE OF THE CELL MEMBRANE
the cell membrane is a thin layer of a partially permable membrane. That protects the cell's organelles and helps to maintain the shape of the cell.
WHAT MATERIALS ENTER OR LEAVE THE CELL MEMBRANE.
since the cell membrane is partially permable, that it only allows some materials to pass through it only nutrients that need to be metabolized or neede by the cell is allowed or permitted to go in the cell either by diffusion or osmosis.
HOW IE ONE METHOD DIFFRENT FROM THE OTHER?
since diffrent materials that go in the cell have different concentrations, sizes, and weights, the method by which they go into the cell will definately be diffrent materials with larger molecules use the osmosis method to go in the cell, while materials with smaller molecules use the diffusion method. I HOPE THIS REALLY HELPED
