If this division is based on tissue formation then it is correct because there are 8 types of cells. If it's based on the function then it's incorrect because there are more than 10.
The answer would be 25%
Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.
Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
The ratio between the force of sliding friction and the normal force of an object is called the coefficient of friction.
Hope this helped :)
The correct answer is that during cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination, the pollen and ovules are from the same plant.
In self-pollination, the pollen from the anther is deposited on the same flower's stigma, or on the stigma of another flower of the similar plant. In comparison, out-crossing or cross-pollination results in greater genetic diversity as the pollen grains and ovules are obtained from different plants.
Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate
