Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Have a great day! :)
I think the answer would be needs. Hope this helps.
Answer:
Index Fossils can be used to identify a specific time period.
Explanation:
Besides producing sugar for itself a plant also needs to absorb nitrogen to build proteins, salts to make concentration gradients and potassium to make enzymes.
<u>Explanation:</u>
Plant sugar is glucose and plants produce it by the process of photosynthesis making use of energy from sunlight, carbon dioxide absorbed from the atmosphere and the presence of chlorophyll in its parts. Plants also require components other than this. Nitrogen is essential to make proteins and it cannot be directly absorbed from the atmosphere but has to be absorbed from the soil.
Potassium is an essential component which is absorbed from the soil. It facilitates the activation of enzymes which play a crucial role in plant metabolism. When plants lack potassium they won’t have enough energy for proper growth and will have poorly formed roots and weak stems.
The best way to identify a mineral is the color of the mineral. The color of the minerals with different impurities is different. The pink color of the rose quartz and the gray color of the smoky quartz indicates that they contain different impurities. The impurities are the main factor behind the color of any mineral.
Hence, the correct answer is 'Color is the best way to identify a mineral'.
