Mlorogla

Answers

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.

Answers

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.

Which of these is TRUE of a neuron at resting potential?
O The neuron has more positive charges inside than outside.
O Sodium-potassium pumps transport sodium ions into the neuron.
O Sodium-potassium pumps transport potassium ions out of the neuron.
O The neuron has more potassium ions inside than outside.

Answers

Answer:

O The neuron has more potassium ions inside than outside.

Explanation:

The membrane resting potential is defined as the difference in electrical charge between the interior of neurons and their outer environment. In neurons, both sodium (Na+) and potassium (K+) pumps contribute to generating the resting potential. Neurons have a higher concentration of K+ inside than outside and a higher concentration of Na+ outside than inside. When a neuron is at its rest state, where the inside is negative with respect to the outside, its membrane is more permeable to K+ than Na+, and therefore the resting membrane potential is closer to the equilibrium potential of K+.

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

Answers

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.

A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid

Answers

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.

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​

Answers

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

new growth is stricken with the blight before it has the chance to mature.

Answers

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.
