Answers

Answer 1

Explanation:

they filter out pathogens they mantain the population of mature lymphocytes
Answer 2

The secondary lymphoid organs are the lymph nodes and spleen, which keep the number of mature lymphocytes in check and filter out infections, hence option B is correct.

What is secondary lymphoid tissue?

The thymus, where T-lymphocytes develop, and red bone marrow, which produces blood and immune cells, are the two main lymphoid organs.

Lymphocytes are also stimulated in secondary lymphoid tissues. Peyer's patches, tonsils, spleen, lymph nodes, and mucosa-associated lymphoid tissue are among them (MALT).

Numerous lymphocytes, a kind of white blood cell, are found in lymph nodes. They produce substances that stimulate other immune system components and aid in the battle against the illness. This is the reason why when you have an infection, your lymph nodes expand.

Therefore, the lymphocytes in your lymph nodes grow if you have an infection, hence option B is correct.

Answers

Answer:

The name for minimum energy expended to keep a resting, awake body alive is. Basal metabolism.

Explanation:

The term for the minimum energy expended to keep a resting, awake body alive is basal metabolic rate (BMR).

What is BMR?

BMR represents the energy required by the body to maintain its vital functions, such as breathing, circulation, and the maintenance of body temperature, when the body is at rest. BMR represents about 60% to 80% of total energy expenditure, depending on a person's age, sex, body size, and other factors.

BMR can be influenced by several factors, including genetics, body composition, and hormone levels. It tends to be higher in people with a higher muscle mass, as muscle tissue requires more energy to maintain than fat tissue. BMR also tends to decline with age, as metabolism tends to slow down as people get older.

how can the rule of nines help indicate whether a burn should be considered critical?

Answers

Answer:

The rule of nines is a tool used to help assess burn severity. See explanation.

Explanation:

The rule of nines divides the body's surface area into percentages, and is a tool to determine what percentage of the body's surface area has been burned.

Head and neck--9%

Chest--9%

Upper Back--9%

Abdomen--9%

Lower Back--9%

Left Arm--9%

Right Arm--9%

Genital Area--1 %

Left Leg--18%

Right Leg--18%

Depending on how much of the body is burned and the location, this can help doctor's assess and treat the burns depending on size and severity. Obviously, the more areas that are burnt, the more severe the burn is.

Wells [1898] But who shall dwell in these worlds if they be inhabited?Are we or they Lords of the World?And how are all things made for man? KEPLER (quoted in The Anatomy of Melancholy)BOOK ONE: THE COMING OF THE MARTIANSCHAPTER ONE: THE EVE OF THE WAR, excerptNo one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable. It is curious to recall some of the mental habits of those departed days. At most terrestrial men fancied there might be other men upon Mars, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us. And early in the twentieth century came the great disillusionment.Yet so vain is man, and so blinded by his vanity, that no writer, up to the very end of the nineteenth century, expressed any idea that intelligent life might have developed there far, or indeed at all, beyond its earthly level. Nor was it generally understood that since Mars is older than our earth, with scarcely a quarter of the superficial area and remoter from the sun, it necessarily follows that it is not only more distant from time's beginning but nearer its end.The secular cooling that must someday overtake our planet has already gone far indeed with our neighbour. Its physical condition is still largely a mystery, but we know now that even in its equatorial region the midday temperature barely approaches that of our coldest winter. Its air is much more attenuated than ours, its oceans have shrunk until they cover but a third of its surface, and as its slow seasons change huge snowcaps gather and melt about either pole and periodically inundate its temperate zones. That last stage of exhaustion, which to us is still incredibly remote, has become a present-day problem for the inhabitants of Mars. The immediate pressure of necessity has brightened their intellects, enlarged their powers, and hardened their hearts. And looking across space with instruments, and intelligences such as we have scarcely dreamed of, they see, at its nearest distance only 35,000,000 of miles sunward of them, a morning star of hope, our own warmer planet, green with vegetation and grey with water, with a cloudy atmosphere eloquent of fertility, with glimpses through its drifting cloud wisps of broad stretches of populous country and narrow, navy-crowded seas.And we men, the creatures who inhabit this earth, must be to them at least as alien and lowly as are the monkeys and lemurs to us. The intellectual side of man already admits that life is an incessant struggle for existence, and it would seem that this too is the belief of the minds upon Mars. Their world is far gone in its cooling and this world is still crowded with life, but crowded only with what they regard as inferior animals. To carry warfare sunward is, indeed, their only escape from the destruction that, generation after generation, creeps upon them.In three to five complete sentences, explain why the inhabitants of Mars are interested in Earth.
