Answer: New growth is stricken with the blight before it has the chance to mature.
Explanation:
American Chestnut trees can indeed regrow from their roots but due to the devastating effect of the chestnut blight, they have been unable to do this since the blight spread across the country.
The blight was introduced when Chinese chestnut trees were imported into the U.S. in the 20th century. It killed off most of the chestnut trees in the U.S. and attacks the tree again when it grows to around 6 meters bringing it down to its roots. This is why the American Chestnut is considered endangered.
Water follows solute so it this case water will follow that 25% solution.
The answer is; 3:1
This is derived by dividing the number of purple flowers with that of white flowers (or vice versa);
669/221 = 3.02714 which is approximately 3 (because we can only have whole plants). Based on this fact, it can be postulated that the Purple flower allele is dominant to that of white flower. (The purple flowers represent the Homozygous dominant and heterozygous population while the white flowers are the homozygous recessive population)
Hello. This question is incomplete. The full question is:
"To demonstrate the arrangement of atoms in liquids, a teacher tapes off a circular section on the classroom floor. How should the students modeling as atoms of liquids stand or move in the taped-off section?
a. They should leave some vacant space and move around one another. b. A few students should move about holding hands in one half of the space. c. They should all squeeze close together so that there is no vacant space. d. A few students should run randomly in the entire space within the section."
Answer:
They should leave some vacant space and move around one another.
Explanation:
The closer the atoms meet, we can say that the more "solid" the substance will be. As the atoms move away, the substance becomes liquid and, moving further away, becomes a gas. Understanding how this works, it is easy to understand the changes in physical state caused by the change in temperature.
In this case, in order for the students to be able to represent the arrangement of the atoms in a liquid substance, they should leave a little free space within the section and move around. If they stayed together to the point where they were unable to move, they would be representing a solid substance. If they left a lot of space in the section and moved at random they would be representing a gaseous substance.
