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.

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.

Explanation:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion has been one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of the osmosis movement of the water takes place.

There are mainly three types of the osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis has been passive transport as water moves from low solute concentration to high solute concentration.

Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.

Therefore, The oxygen cross into the cell as water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).

Answer:

D

Explanation:

How many moons does Saturn have? A total of 82 confirmed moons, surpassing even Jupiter, which has 79. There could be even more hidden moons that orbit around Saturn, and as such, this gas giant will be from now on not only recognized for its prominent rings but also its numerous moons.

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.

Answer:

to cut DNA into fragments of different lengths

Explanation:

A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.

More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading viral bacteriophages. Restrictions sites in the viral genome (a "happy accident" of nature, as far as the bacteria are concerned, since they don't appear to have any specific function in the virus) are cleaved by the bacterium's restriction enzymes, fragmenting and destroying the DNA of invading bacteriophages before it can incorporate into the host's genome and take over the cell.

A bacterium is immune to its own restriction enzymes, even if it has the target sequences ordinarily targeted by them. This is because the bacterial restriction sites are highly methylated, making them unrecognizable to the restriction enzyme.

Isn't evolution fantastic?

The correct answer is option C i.e. to cut DNA into fragments of different lengths.

A restriction enzyme is a bacterial protein that cleaves DNA sequences at sequence-specific places, resulting in DNA fragments with known sequences on both ends.

Certain laboratory processes, such as recombinant DNA technology and genetic engineering, require the use of restriction enzymes.

There are four different types of restriction enzymes: type I, II, III, and IV, which differ principally in structure, cleavage site, specificity, and cofactors.

Both restriction and methylase functions are carried out by a single big enzyme complex in Types I and III enzymes.

The restriction enzyme is independent of its methylase in the Type II system.

Several thousand type II restriction enzymes have been identified from a variety of bacterial species.

These enzymes recognize a few hundred distinct sequences, generally four to eight bases in length.

Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.

Type IV restriction enzymes cleave only methylated DNA and show weak sequence specificity.

hence, the correct answer is option B.
