The pressure on the inner core makes the inner core into a solid state, the temperature is hotter that the outer core but it's not hot enough to melt a substance do to the pressure squeezing down from all the layers above!
Answer:
The pressure on the inner core puts the inner core into a solid state, therefore the temperature is hotter than the outer core, but not enough to melt a substance due to the pressure squeezing down from the other layers 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.

Use the paragraph to answer the question. A team of biologists has been investigating fireflies to determine the cause of their declining population. Habitat loss is the most likely factor in the decline of the bioluminescent bug. Light pollution also plays a role. Excessive light disrupts the insect’s mating ritual. Write one to two sentences giving an example of technical language in this paragraph and explaining how it affects the overall meaning of the paragraph. (2 points)
Explanation:
Biologists have discovered that the reason behind the decline of fireflies is habitat loss, light pollution and excessive light; excessive light can disrupt the insects mating ritual.
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.
A teacher performing a demonstration finds that a piece of cork displaces 24 mL of water. The piece of cork has a mass of 6 g. What is the density of the cork?
Answer:
0.25 g/cm³
Explanation:
Density is the ratio of mass to volume:
(6 g)/(24 mL) = 0.25 g/mL = 0.25 g/cm³
_____
1 mL = 1 cm³. Units of density in the cgs unit system are g/cm³.

Explanation:
Which tectonic plate boundary caused the structure that is circled in the image?
Answer:
I'm guesssing it's B? I did this a very long time ago( two weeks ago)
Explanation:
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.

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.

How is static electricity created?
a. Two objects that are both positively charged repel each other and release
electric energy.
b. Two objects that are both negatively charged become attracted and create a
spark.
c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.
Answer:
d
Explanation:
So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.
Answer:
d. Friction between two objects causes a transfer of electrons from one object to the other.
Explanation:
If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.
