Un niño que ha enfermado de paperas o varicela, no desarrollará estas
enfermedades en una segunda oportunidad, porque:
I. la piel, mucosas y lágrimas impiden el ingreso de los microbios.
II. en el primer contacto adquirió anticuerpos.
III. interviene la inmunidad Adaptativa, la cual presenta "memoria".
IV. su sistema defensivo está preparado frente a una segunda exposición
a. I y II son correctas
b. III y IV son correctas
c. II, III y IV son correctas
d. I, II y III son correctas.
Respuesta:
La respuesta correcta es la C, ya que II, III y IV son correctas.
Explicación:
Nuestro sistema inmunológico nos defiende de agentes patógenos que pueden enfermarnos, y está compuesto por dos tipos distintos de inmunidades: la inmunidad innata y la inmunidad adaptativa.
La inmunidad innata es aquella que reacciona primero cuando se presenta una amenaza, atacando a los patógenos de manera inespecífica gracias a mecanismos que ya existían antes de que se desarrolle la infección. Cuando se trata de inmunidad innata, nuestras principales barreras de defensa son la piel y las mucosas, y las células de la respuesta inmune de mayor relevancia son los neutrófilos, entre otras.
Por el contrario, la inmunidad adaptativa, es de respuesta tardía y puede actuar de maneras diferentes dependiendo de cuál sea el patógeno invasor. Hay dos tipos de inmunidad adaptativa, la humoral y la celular. De la inmunidad humoral participan principalmente los linfocitos B, que fabrican anticuerpos específicos; mientras que la inmunidad celular es llevada a cabo por linfocitos T. La ventaja que tiene la inmunidad adaptativa en comparación con la innata es que es específica, diversa, más eficaz, y POSEE MEMORIA.
Las células de la inmunidad adaptativa presentan la capacidad de "recordar" cómo el cuerpo actuó ante una amenaza en el pasado para poder llevar a cabo un plan mucho más eficaz. Esta es la razón por la que las vacunas funcionan: porque se le inyecta a los individuos una versión débil del patógeno (por ejemplo, del virus que causa la varicela) para que el cuerpo "aprenda" a vencerlo para cuando se encuentre con ese microorganismo en un futuro.
Explain the origin and importance of the buildup of free oxygen in the atmosphere for the evolution of animal life.
Answer:
Prior to the buildup of oxygen, organisms were mainly anaerobic and used mechanisms where no oxygen was present or needed. Once the buildup of oxygen starting occurring, organisms were forced to either evolve to survive or they would die off due to the presence of oxygen. The organisms needed to evolve so that they could use and benefit from the abundance of oxygen. The presence of oxygen is a huge evolutionary milestone that kick started the evolution of many new species. Organisms began to metabolize and perform all of its functions with oxygen present.

Pollution may be defined as any form of unwanted substances or impurities which are present in the atmosphere of the earth that harm the lives of living entities.
Human and animal wastes, industrial wastes, and agricultural chemicals are potent sources of freshwater pollution.
Pesticides are generally spread in the agricultural fields to protect the crop from pathogens and are most likely to be found in runoff from farm fields during the rainy season.
An Estuary is a mini-ecosystem in which freshwater meets the marine water near the sea.
Therefore, it is well described above.

Two differences between hormones and the nervous system
Answer:
Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
Explanation:
Answer:
the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Which of the following is NOT evidence of plate tectonics?
1. distribution of fossils
2. location of earthquakes
3. rain forest depletion
4. the shape of the continents
Rain forest depletion is not evidence of plate tectonics.
• Plate tectonics is responsible for the distribution of fossils on distinct continents, for the continental and ocean floor features comprising volcanoes, mountains, trenches, and faults, for the occurrence of earthquakes, and the shape of the continents.
• On different continents, the fossils are identical to the fossils found on the continents, which were once connected.
• The majority of the oceanic and continental floor features are the outcome of the earthquake and geological activity along the plate boundaries.
• The depletion of rainforest is not a result of plate tectonics. The major reason for rainforest depletion are agriculture and fuelwood collection.
• Apart from this, some of the human activities like logging, mining, development of large dams and industry is also major cause of rainforest depletion.
Thus, rainforest depletion is not evidence of plate tectonics.
