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.

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+.

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.

I hope this answers your question! :)

Answer:

It is because of the axis it is on!

Explanation:

In fact, in the Northern Hemisphere, the orbit of the earth takes us further from the sun in summer. Summer is hotter than winter due to the tilt in the axis of the earth of 23 degrees. ... – the sun is higher in the sky, meaning more sunlight shines on the earth more directly.

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

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.

Explanation:

How does the Coriolis effect make ocean currents appear to move? ... The Gulf Stream Current is deflected by North America, causing the current to change direction.

How does the Coriolis effect affect ocean currents?

The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in.

How does the Coriolis effect change the motion of wind and ocean currents?

As wind or an ocean current moves, the Earth spins underneath it. ... The Coriolis effect bends the direction of surface currents to the right in the Northern Hemisphere. The currents curve left in the Southern Hemisphere (Figure below). The Coriolis effect causes winds and currents to form circular patterns.

Where is the Coriolis effect the strongest?

poles

11. Earth's rotational effects on horizontally and freely moving objects are greatest at the poles; therefore, the Coriolis effect is greatest at the poles.

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.

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.

Explanation:

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.

DNA polymerase III is a holoenzyme, which has two core enzymes (Pol III), each consisting of three subunits (, and ), a sliding clamp that has two beta subunits, and a clamp-loading complex which has multiple subunits (, , , , and ).

Explanation:

The subunits used to make product in DNA replication are:

I. Alpha (α) subunit.

II. Delta ([tex]\delta[/tex]) subunit.

III. Epsilon ([tex]\epsilon[/tex]) subunit.

Nucleus is the most conspicuous cell organelle that is found in all eukaryotic living organisms.

Basically, the nucleus serves as the site for ribonucleic acid (RNA) synthesis and deoxyribonucleic acid (DNA) replication.

DNA replication can be defined as a biological process through which two identical replicas of deoxyribonucleic acid (DNA) molecules are produced from an original deoxyribonucleic acid (DNA) molecule, especially during cellular division.

This ultimately implies that, DNA replication is a biological process that occurs during cellular division and it involves the duplication of a double-stranded DNA to produce two identical deoxyribonucleic acid (DNA) molecules.

The three (3) main subunits (polymerases) used for making products in DNA replication includes the following:

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.
