Answer:
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Explanation:
The correct answer is (d) It is smaller and does not give shape to the animal cell.
Animal cells have smaller vacuoles as compare to that of plant cell. It does not decides the shape of the of the animal cell. The main function of vacuoles in animal cell is endocytosis and exocytosis. They store the waste material. In plant cell the vacuoles cover almost 90% of the space and decides the shape of the plant cell as they are filled with water. This helps the plant cell to maintain turgor pressure.
Lol . To answer your question, proteins in animals are made by the consumption of food. They are packaged in a way where they are broken down and converted into energy, sugars and PROTEINS. They are transported and aided with the Golgi Apparatus. If you need more help I would just search each peice of your question individually
Answer:lakes and swamps
Explanation:any thing that is not man made
Answer:
D. None of the above
Explanation:
<u>Reason that Drastic Change in weather may cause mass extinction</u>
Weather plays an important role in the survivability & the growth/diminish of the population. For example, animals that need large amounts/bodies of water (for example fishes), will not survive when the area is hit with a heat wave & drought, which would cause fishes to surface, and die.
<u>Reason that Geological change would play a large role in mass extinctions</u>
While the Geography is constantly changing, large abrupt changes would cause a upheaval and may upset the population, leading to a depletion of resources or even a sudden destruction of part/all of the population. For example, an earthquake may kill large amounts of animals, and the destruction of the greenery in the area may severely limit the amount of food/decrease the primary consumer's populations, leading to a starvation.
