Answer:
All are true of the movement of Earth's atmosphere except :
d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.
Explanation:
- When gases heat up, their volume increases and density decrease.
- A decrease in density causes a substance to become lighter.
- Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
- So, it will move up.
- The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
- Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
False
Bacteria are known as decomposers and feed off waste or dead organisms while viruses are known as parasites and are a small collection of genetic code that surrounds a protein and infects a host cell to produce more replicas of itself. This process usually kills the host cell.
That sounds like a statement because she has no scientific backing that ALL bulldogs are great pets and only has experience with one.
Answer:
The correct answer is - lysosome and vacuole.
Explanation:
In the cells of animals and plants, there are many similarities and some differences as well. These similarities and differences include the organelle they both have common or specific to a particular cell.
Lysosome and the vacuoles are two organelles found in both cells; plants, and animals. In plants, there is a central vacuole large in size whereas in the animal cells the numbers are much higher and size is smaller in size. Lysosomes are also present in both animals as well as the plant cell.
Thus, the correct answer is - lysosomes and vacuole.
