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.
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.
Answer :
The answer is That percentage of composition of Zinc as determined said to be 19%, the percentage of iodine 81% and it shows that it is very close to accepted values by making calculations.
Explanations:
When iodine is dissolved in a strongly polar substance such as menthol. As the reaction is progressed, the color of the solution going from its initial color. Furthermore, after the reaction, small grey pallets supports the percentage between iodine reacted with the zinc. All the iodine reacted whereas portion reacted while the rest remained untouched.
The process is called facilitated transport when molecules must join with another molecule, such as proteins, to get through a membrane.
If you meant nucleic acid, it would be DNA or RNA
