Answer:
True.
Explanation:
Mitochondria and chloroplast are the important cell organelle present in the organism. Mitochondria is used for the generation of ATP whereas chloroplast is used for the photosynthesis in plants.
Endosymbiont theory explains the evolution of mitochondria and chloroplast. According to this theory, the free-living prokaryotes taken from the inside of other prokaryotes and later evolve into mitochondria and chloroplast.
Thus, the correct answer is option (a).
Answer:
The low pH of the lysosome is maintained by membrane proteins that pump protons (H + ions ) from the cytosol into the lysosome. ... Although it may seem dangerous for cells to contain enzymes that can digest most biological molecules, the contents of the cell are doubly protected from the digestive enzymes of the lysosome.

Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
