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.

Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.
An advantage of using synthetic fertilizer instead of organic fertilizer is that
A synthetic fertilizer can provide more targeted macronutrients to the crops
B) synthetic fertilizer remains in the soil longer than organic fertilizer does, reducing the volume needed and, therefore, the cost to the farmer
c) synthetic fertilizer adds to soil texture and increases the soil's water-holding capacity
organic fertilizer runs off more readily into waterways, leading to nutrient overload
An advantage of using synthetic fertilizer instead of organic fertilizer is that
synthetic fertilizer can provide more targeted macro nutrients to the crops.
Synthetic fertilizers are used by farmers to increase crop yield. The fertilizer
are specially formulated to ensure all the macro-nutrients are present in the
right proportions for optimal yield of the crops.
This is the advantage synthetic fertilizers have as organic fertilizer don't
contain all the targeted macro nutrients in the right amounts.

Which of the following statements best describes the importance of
nutrient cycling?
Answer:
Since there are no choices to this question, I think it restores ecosystems or the organisms physical environment to a state called the "Equilibrium State".
Explanation:
The Equilibrium State keeps the ecosystems functioning. Nutrient cycles link or put the living organisms with the non living organisms together throughout the flow of the nutrients in the cycle. Remember that living and non living organisms always depend on each other.

A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
What are some functions of the Thalamus.
Answer:The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The primary function of the thalamus is to relay motor and sensory signals to the cerebral cortex
Explanation:
A 66-year-old man has difficulty controlling voluntary movements. He can clearly state what he intends to do, describe how he would do it, and initiate or stop the movement. However, he has poor coordination and often misses his target. If his difficulty arises from a defect in one particular area of the central nervous system, which area is most likely to be involved
Answer:
Cerebrum
Explanation:
Cerebrum is the part of central nervous system that is responsible for the voluntary movement. If there is poor coordination between cerebrum and the muscles so the person has difficulty in controlling his voluntary actions or movement. Somatic nervous system is a part of the peripheral nervous system responsible for the voluntary movements of body parts through the use of skeletal muscles so we can say that both cerebrum and somatic nervous system is responsible for voluntary actions.

Which of the following is an example of primary succession?
A. the recovery of Yellowstone National Park following the fires of 1988
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
C. the growth of weeds in a field after a farmer stops using the field
D. the growth of weeds in an empty lot that is no longer being mowed
Answer:
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
Explanation:
Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.
Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.
According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

Explanation:
when 70.0 grams of mno2 reacted with 128.0 grams of hcl, the reaction resulted in a 62.7% yield of chlorine gas. what is the actual yield of chlorine gas in grams? Mno2 + HCI —> MnCl2 + H2O + Cl2
Answer:
35.7 g
Explanation:
yield(%) = actual yield/theoretical yield x 100
We can calculate the theoretical yield by considering the balanced chemical equation:
MnO₂ + 4HCI —> MnCl₂ + 2H₂O + Cl₂
According to the equation, 1 mol of MnO₂ reacts with 4 moles of HCl to produce 1 mol of Cl₂. So, we can write the following mole ratios:
1 mol MnO₂/4 mol HCl or 4 mol HCl/1 mol MnO₂
1 mol MnO₂/1 mol Cl₂
4 mol HCl/1 mol Cl₂
As we have the amounts of reactants in grams, we have to convert from moles to mass by using the molecular weight (MW) of each compound:
MW(MnO₂) = 54.9 g/mol Mn + (16 g/mol x 2 O) = 86.9 g/mol
1 mol MnO₂ x 86.9 g/mol = 86.9 g MnO₂
MW(HCl) = 1 g/mol H + 35.4 g/mol Cl = 36.4 g/mol
4 moles HCl x 36.4 g/mol = 145.6 g HCl
MW(Cl₂) = 2 x 35.4 g/mol Cl = 70.8 g/mol
1 mol Cl₂ x 70.8 g/mol = 70.8 g Cl₂
Now, we have to figure out which is the limiting reactant. For this, we use the stoichiometric ratio: 145.6 g HCl/86.9 g MnO₂. We multiply the actual amount of MnO₂ by the stoichiometric ratio:
70.0 g MnO₂ x 145.6 g HCl/86.9 g MnO₂ = 117.3 g HCl < 128.0 g HCl
We need 117.3 grams of HCl to completely react with 70.0 grams of MnO₂, and we have 128 grams of HCl. So, the reactant in excess is HCl, and the limiting reactant is MnO₂.
With the limiting reactant, we calculate the theoretical yield of Cl₂. We use the stoichiometric ratio 70.8 g Cl₂/86.9 g MnO₂:
70.0 g MnO₂ x 70.8 g Cl₂/86.9 g MnO₂ = 57 g Cl₂
Finally, we calculate the actual yield of chlorine gas (Cl₂), by using the first equation:
yield(%) = actual yield/theoretical yield x 100
⇒ actual yield = theoretical yield x yield(%)/100
= 57 g x 62.7%/100
= 35.7 g
Which of the following metabolic pathways does NOT directly produce lots of ATP (also called anaerobic cycle)?
A. Glycolysis
B. Krebs cycle
C. Citric acid cycle
D. Electron transport chain
Answer:
A. Glycolysis
Explanation:
Glycolysis is the first stage of cellular respiration, which occurs in the cytoplasm of the cell. Glycolysis does not require oxygen to occur, hence, it is carried out by both prokaryotic and eukaryotic organism.
Glycolysis, among the other stages of cellular respiration, produces the least ATP (2). Hence, Glycolysis is the metabolic pathway that does NOT directly produce lots of ATP.

Mlorogla
Answer:
Astrocytes are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by satellite cells.
The ventricles of the brain are lined with ependymal cells, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called microglia.
The myelin sheath of the Central Nervous System is formed by oligodendrocytes.
Axons of unipolar neurons are insulated by Schwann cells, which increase the speed of the electrical impulse.
Explanation:
The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.
Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.
Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.
Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.
The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.
The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.
