Viruses do not have nuclei, organelles, or cytoplasm like cells do which is why they have no way to monitor or create change in their internal environment.
Answer: Option D) China
Explanation:
From the picture provided, China and USA contributes above 5.000.000 ( In thousands of metric tons) of carbon dioxide emissions.
And since carbon dioxide has been implicated in the emergence of global climate change, both countries are leaders in the emission.
Thus, China is the right option
Answer:
Temperature
Altitude or Elevation
Moisture or water vapour.
Explanation:
Answer:
The difference is due to the succeeding vowel sound strength (whether it is weak or strong)
Explanation:
"ch" produces "k" like sound. Whenever , alphabet "c" with in any word comes before any weak vowel sound such as i or e , it always sound as "ch".
Therefore, c and ch in gioco and giochi are sound similar.
"sc" sounds like "sh" when it comes before any weak vowel sound (as in the case of capisci)
"sc" sounds like "sk" when it comes before any strong vowel sound (as in the case of capisco)
Answer:
All options are correct
Explanation:
Fossils are the remains of organisms (animals and plants) preserved in a rock. Scientists (geologists & palaebiologists) have used fossils to study the diversity of organisms in the past. This is based on their preserved morphological features. For example, several species of foraminifera has been identified in the rocks. Among them, some species are present today whereas others have become extinct.
Similarly, fossils are the indicators of past climate (e.g. temperature) as well. This means, if a specific species can survive at a particular temperature, its presence suggest that particular environment. For example, corals survive in tropical waters at specific depth and sunlight. So, if we find corals fossils, the cliamte of that particular age would be roughly the similar.
In the end, fossils can also provide evidence of orogeny (mountain building) process. These are typically plants fossils which cannot move and their remains are preserved in the folding rocks.
