Even though chestnuts can regrow from their roots, this does not usually happen because
there are few root systems left in the forest.
chestnuts grow in regions prone to fires.
most forestry professionals no longer want to grow chestnuts.
new growth is stricken with the blight before it has the chance to mature.
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.

The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop
Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain
Answer:
An antisense sequence with complementary to the target mRNA encoded by the gene of interest
Explanation:
An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.

View Available Hint(s) Which of the following best describes the biological role of the lac operon? It ensures that bacterial cells produce lactose only when no other food sources are available. It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment. It ensures that a cell produces enzymes involved in lactose metabolism in a constitutive manner. It prevents other sugars from being metabolized until all available lactose has been used. Submit Part C The placement of the operator sequence between the promotor and the structural genes is critical to the proper function of the lac operon. View Available Hint(s) The placement of the operator sequence between the promotor and the structural genes is critical to the proper function of the lac operon. True False
Options for part A are as follows:
A) A mutation in the operator sequence
B) A mutation in the lac-Z gene
C) A mutation in the lac-Y gene
D) A super repressor mutation
Answer:
The correct answer:
Part a - A mutation in the operator sequence
Part b - It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part C. true.
Explanation:
part a:
If there is a mutation in the operator sequence leads to prevent binding of the repressor which leads to allowing constitutive expression of the genes various conditions.
part b:
The biological role of the lac operon makes sure that the cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part c:
RNA polymerase cannot transcribe the structural genes due to the repressor binds to the lac operator, therefore, the proper function of the lac operon is possible when the placement of the operator sequence between the promotor and the structural genes.
Which of the following is a true statement? Physical property change is always better than chemical property change.
o Physical and chemical propery change can happen at the same time.
Chemical property change is better than physical property change.
Answer:
the second one
Explanation:
Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.
Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.
none are better, depending on for what

1..Buccal respiration
2..Cutaneous respiration
3.. Pulmonary respiration
Answer:
1.Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent.
2.Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs.
3.Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation.

sedimentary rock. Which of these processes would be the correct label to
replace the question mark?
Metamorphic rock
Sediment
Sedimentary rock
Erosion
?
A) Cooling
B) Deposition
C) Melting
D) weathering
Answer:
The process that would be the correct label to replace the question mark in this question is:
B) Deposition
Explanation:
Deposition takes place after erosion of sedimentary rock. At this stage, the eroded sedimentary rocks build up under high pressure heat, wind, ice, water, and other natural forces to originate the rock formation cycle once again. Naturally, after deposition, the igneous rocks, which have then layered up sedimentary rocks to become metamorphic rocks.

The ovarian cycle is the monthly series of changes that occur in a female's ovaries, specifically in the development and release of an egg (ovulation).
The cycle is regulated by several hormones produced by the hypothalamus, pituitary gland, and ovaries, and is divided into three main phases: the follicular phase, the ovulatory phase (or ovulation), and the luteal phase.
