When CFCs are exposed to high levels of UV radiation, what occurs? A. The compound breaks down into nitric oxide and ozone. B. All of these C. A chlorine breaks off and forms a free radical. D. They become ionized and stick together in clumps that become part of smog.

Answers

Answer 1

Answer:

C. A chlorine breaks off and forms a free radical

Explanation:

When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.

These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.

CFCs are main cause of ozone depletion in the atmosphere.

Hence, the correct option is "C".

The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation

Answers

Answer:

adaptation

Explanation:

Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.

In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.

Therefore, this is an example of ADAPTATION.

What are the three basic parts of the cell theory?

Answers

Answer:

Answer

Explanation:

All living things are composed of cells.

Cells are the basic units of structure and function for living things.

All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

The three basic parts of the cell theory are:

All living things are made of cells.

Cells come from preexisting cells.

All cells have the same basic parts.

How do we explain?

Cells are the basic unit of life. All living things, from the smallest bacteria to the largest redwood tree, are made up of cells.

Cells are not created spontaneously. All cells come from the division of preexisting cells.

Despite their great diversity, all cells have the same basic parts, including a plasma membrane, cytoplasm, and DNA.

The cell theory was first proposed by Matthias Schleiden and Theodor Schwann in the 1830s. It has since been supported by a vast body of evidence from cell biology. The cell theory is one of the most important and fundamental concepts in biology.

Dump out half of the particles. Place your hand tightly over the top and shake the container. Then remove most of the remaining particles, and shake the container again. Compared with the full container, which states of matter do these two models most closely represent? Explain.

Answers

Answer:

solid

Explanation:

The two models explained are most closely representing the "solid" state.

As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.

Hence, the correct answer is "Solid".

Answer:

When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.

Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
a. hypoxemic hypoxia
b. ischemic (stagnant) hypoxia
c. anemic hypoxiad. histotoxic hypoxia

Answers

Answer:

c. Anemic hypoxia

Explanation:

Hypoxia is a health condition in which the body or a region of the body is not adequately supply with oxygen  at the tissue level. Types of hypoxia include:

Hypoxemic hypoxia is a condition in which their is low level of oxygen in blood in the arteries due to the inability of the lungs to properly oxygenate blood.

Ischemic (stagnant) hypoxia is a type of hypoxia that occurs due to a decrease in blood flow preventing adequate blood supply to tissues.

Anemic hypoxia occurs when the ability of the blood to carry oxyegen is reduced due fewer red blood cells or red blood cells that contain little or abnormal hemoglobin molecules hemoglobin molecules.

Histotoxic hypoxia is hypoxia in which the cells are unable to use oxygen from the bloodstream, even though there is normal delivery of oxygen to such cells and tissues. This is due to the poisoning of the cells or tissues causing a disruption in their respiratory mechanism, for example in Cyanide poisoning.

Therefore, the correct answer is anemic hypoxia.

At label ________, the cell is not hyperpolarized; however, repolarization is in progress, as the sodium channels are inactivated or becoming inactivated, and many potassium channels have opened.

Answers

Answer: C

Explanation:

When a neuron receives a stimulus, the sodium channels present in the membrane are opened, and therefore Na+ enters the cell in favour of the concentration gradient, so that the membrane potential changes to positive by means of ion exchange, producing depolarization. If this depolarization reaches a certain threshold value, an action potential is generated. The next step is the opening of the potassium channels and the inactivation of the sodium channels, so that the repolarization of the membrane takes place. The sodium channels, will return to the closed state in the hyperpolarization to continue in this state during all the rest potential achieving the action potential to return to -70 mV (repolarization).; until the arrival of a new action potential which produces the activation and opening of the sodium channels, repeating the cycle again and generating a new depolarizing action. This process is part of the synaptic transmission.

So, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. This means, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in membrane voltage where the membrane potential is more distinctly positive or negative are hyperpolarizations.

During the repolarization period after an action potential, the membrane potential is more negative than when the cell is in "rest period". In the picture, this repolarization period is about 1-2 milliseconds. So, repolarization is the time in which the membrane potential is hyperpolarized with respect to the resting potential.

In the attached figure, part C indicates this repolarization period.

Answers

Answer:

Explanation:

 (a) Dry apricots when placed in pure water swell due to osmosis and when in sugar water, they shrink again.

(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.

(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.

(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.

(e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosomes. Thus, when ribosomes are removed the cell will not function properly
