Cross-pollination
occurs when pollen from one plant transferred to a different plant with same
species. <span>The two
plants’ genetic material combines and the resulting seeds from that pollination
will have characteristics of both varieties thus producing stronger
plants. In addition, cross- pollination happens
in several means through the help of wind, insect or humans. </span><span>

Answer: um is this a question or are you just telling people
Explanation:
Answer: Infusion time is 5.5 h
Explanation: Time is 470 ml / 85 ml/h = 5.5 h
Answer:
2.94 x 10⁻¹⁴L
Explanation:
To solve this problem, we have to assume that the condition of this water is at standard temperature and pressure, STP.
At STP;
1 mole of gas have a volume of 22.4L
So, let us find the number of moles of this water first;
6.02 x 10²³ molecules can be found in 1 mole of a substance
7.89 x 10⁸ molecules will contain 
= 1.31 x 10⁻¹⁵mole of water
So;
Volume of water = 22.4 x 1.31 x 10⁻¹⁵ = 2.94 x 10⁻¹⁴L
Answer:
See explanation
Explanation:
If we look at the structure of X, we will discover that X is an organic compound. The compound will certainly have a much lower melting point than sand.
This is because, sand is composed of high melting point inorganic materials.
Hence, even though the researcher accidentally spilled some sand into the the beaker containing the crystalline substance X, he does not need to be perturbed since the melting point of X is much lower than that of sand
