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?

Extensive damage to oligodendrocytes in the CNS could result in reduced speed of nerve impulses. a breakdown of the blood-brain barrier. loss of the structural framework of the brain. inability to produce scar tissue at the site of an injury. decreased production of cerebrospinal fluid.

Answers

Answer:

Loss of the structural framework of the brain.

Explanation:

Damage to oligodendrocytes in the central nervous system leads to the loss of the structural framework of the brain. oligodendrocytes produce the insulating sheath of axons and we know that axons are the nerve fiber that conducts electrical impulses away from the neuron's cell body. Axons are the primary transmission lines of the nervous system that carries impulse throughout the body so if the oligodendrocytes are damaged then our brain did not work properly.

If oligodendrocytes are damaged, the myelin sheaths around axons can be destroyed. This can lead to a loss of the structural framework of the brain, as the axons will no longer be properly insulated. Hence option C is correct.

Oligodendrocytes are glial cells in the central nervous system (CNS) that are responsible for myelinating axons. Myelin is a fatty sheath that surrounds axons and helps to speed up the conduction of nerve impulses.

The loss of the structural framework of the brain can cause a variety of neurological problems, including:

Reduced speed of nerve impulses. As mentioned above, myelin sheaths help to speed up the conduction of nerve impulses. Without myelin sheaths, nerve impulses will travel more slowly, which can cause problems with coordination, movement, and sensation.

Increased risk of seizures. Seizures are caused by abnormal electrical activity in the brain. When the myelin sheaths around axons are damaged, it can increase the risk of seizures.

Cognitive impairment refers to a decline in thinking and memory skills. Damage to oligodendrocytes can lead to cognitive impairment, as the axons will no longer be able to function properly.

Therefore, option C) loss of the structural framework of the brain is correct.

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

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.

How are living organisms linked within an ecosystem? A. by their physical adaptations B. by what they eat C. by their size D. by their habitat
ILL GIVE BRAINLIST!!!PLEASE HELP!!​

Answers

Answer:

B

Explanation:

Living Organisms in an ecosystem have a food chain or energy chain. This chain links all organisms within an ecosystem, therefore, answer B "By what they eat" should be the correct answer

Organisms are linked within an ecosystem by their physical adaptations.

What is physical adaptation?

Physical adaptations are special body parts that help a plant or animal survive in an environment.

A physical adaptation is some type of structural modification made to a part of the body.

A behavioral adaptation is something an animal does - how it acts - usually in response to some type of external stimulus.

what is  an Ecosystem?

An ecosystem is made up of all species and the physical context in which they interact.

Nutrient cycles and energy flows connect these biotic and abiotic components.

Photosynthesis enters the system, absorbing energy and storing it in plant tissue.

Animals assist in the transmission of nutrients and energy throughout the system by eating plants and each other.

Both external and internal factors have an impact on ecosystems.

The availability of diverse resources within the ecosystem is determined by internal factors, whilst resource inputs are usually governed by external activities.

Ecosystem mechanisms thus regulate as well as control interior elements.

so the correct answer is option A.

Identify the type of reproduction the botanist should use to develop the new
spider plants and explain why this type of reproduction is preferable.

Answers

Answer: The botanist should use sexual reproduction to make the new plants because asexual reproduction will only produce spider plant offspring with the same types of traits as the parents.

Explanation:

Assuming that the botanist already has spider plants with larger flowers in their nursery, in order to develop a large number of the plant based on the same traits, asexual reproduction method should be used.

Asexual reproduction method is preferred because:

the daughter plants come out with exactly the same traits as the parent plant,large number of plants can be produced at once

Sexual reproduction leads to variation such that daughter plants will not have exactly the same traits as their parents. The number of plants that can be produced sexually is also limited.
