Answer:
6
Explanation:
To find the mean of a data set, add all the values in the set together, and then divide the result by the number of values in the set.
3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48
There are 8 values in the data set.
48/8 = 6
So the mean of the data set is 6.
Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds. However, not all plants reproduce flowers. Simpler plants, like mosses, lack these specialized structures.
Cells for sexual reproduction is meiosis
Answer:
1. Essential organs form during early development
Explanation:
Harmful chemicals (toxins) cause the most disease when they are present during fetal development, because organ systems are being developed and the rate of growth is very fast.
The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.
<u>Explanation:
</u>
It is 4.5 billion years that <em>Earth has been formed and there have been changes since then</em>. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
