Answer:
Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function.
Answer:
Endosymbiont theory was proposed by Lynn Margulis in 1967 which suggested the origin of Chloroplast and mitochondria in eukaryotic cells.
The theory suggested that chloroplast and mitochondria organelle originated by engulfing the cyanobacteria and proteobacteria by other prokaryotic bacteria.
This shows that Prokaryotes exhibit the following characters:
1. These were the first organisms on Earth
2. Lack membrane-bounded
3. Aerobic bacteria are these types of cells
Eukaryotes exhibit:
1. Have mitochondria
2. Includes organisms that carry out aerobic respiration
3. Can be a multicellular organism
4. Includes organisms that are photosynthetic
5. Might have chloroplasts
Answer:
They are veins and arteries. The primary function of arteries is to transport highly oxygenated, nutrient-rich blood from our hearts and distribute it to the rest of our body. Veins, on the other hand, are used to pump much-needed blood back to the heart.
The answer should be Genes
Answer: phagocytosis; lysosomes
Collar cells in the sponge digest food through phagocytosis or by using enzymes that come from the lysosomes. Bacteria are among the elements that are broken down by phagocytosis with the help of some specific enzymes found in lysosomes.
