Answer:
“Stromatolites are pervasive in the fossil record and are some of our earliest examples of life on Earth,” he says. “The microbial mats that created them were predominantly made up of cyanobacteria, which used photosynthesis – like plants do – to turn sunlight into energy while producing so much oxygen over time they changed the early Earth’s atmosphere to make it habitable for complex life.
Answer:
Explanation:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. ... Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
Answer:
Option (B).
Explanation:
The process of cell differentiation in the embryonic stage is important for the cell to differentiate into a specific cell type. The cell differentiation also occurs in the adult stages also.
Various experiments have been done to find the evidence of cell differentiation. The occurrence of the specific mRNAs for the formation of tissue specific proteins provide the evidence that cell differentiation occurs in the embryonic stage.
Thus, the correct answer is option (B).
I believe it’s the metaphase
For the answer to the question above for property damage, one example we could give is buildings or houses. Erosion decreases the value of this properties because the materials like metal are oxidizing and rust overtime and the structure's strength is decreasing over time. As for damage to crops. the land's nutrients decrease overtime too. Which means the crops can get fewer nutrients from the soil in order to perform Photosynthesis.
The long-term effects of this things on humans are things get riskier. Like a car. A 20-year-old car isn't the same as a brand new car in whatever ways. The brand new cars are safer because the materials that are used there are newer than the old car and they are more reliable. Same for humans. A 5-year old's health is not the same as a 50-year-old's health.
