Answer:
Heart disease is a non communicable disease because it does not happen due to any virus or bacteria.
Explanation:
Diseases caused due to virus and bacteria are mostly communicable. Heart Disease is caused due to poor supply of nutrients in hearts.
Answer:
1. Mitochondria
2. Chloroplast
3. the formation of eukaryotic cells
4. DNA
Explanation:
The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.
The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.
The evidence which supports their ar:
1. The same size of the organelles to the bacteria
2. The presence of the circular DNA of the organelles like bacteria
3. The similarity in the 30s and 70s ribosomal subunits.
Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:
there is an abundance of fertile soil
climate and fertile soil are crucial for plant growth
eukaryote is a single celled organism, so that is almost like every organism on earth (except for bacteria). so actually there are many examples
1. bananas
2. algae
3. a spider
4. a lion
5. mushroom
4. tress, grass, flowers, pines....etc
5. humans
6. cancer cells, animal cells, sperm cells, muscle cells, plant cells...etc
5. flies almost every type of fly
6. fish
so yeah you get it almost every organism is a single celled organism :D
(except for bacteria and virus)
