Two differences between hormones and the nervous system

Answers

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 presents the best argument as to the role of the cow in this cycle?

Answers

Answer:

Cow dung helps in balancing the environment and kills germs

Explanation:

Cow dung is used for fertility of the soil. It is also used for the control of pest in the plants. When heated cow dung can be used to cook food where there are lack of wood available. Also when it is heated it releases the gases which kills germs present in the air.

Answer:

The cow eats plants and produces carbon dioxide through cellular respiration. The plants, which gain energy from the sun, then take carbon dioxide from the atmosphere and use it in photosynthesis.

Fungi have characteristics that make them similar to both plants and animals. Which characteristic do fungi share with plants but not animals?

·reproduce sexually
·contain nuclei
·have cell walls
·make their own food

Answers

Explanation:

·have cell wall

cell wall is present in plant and fungi due to protection

but not in animals due to locomotion mode of life

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.

What are the characteristics of fungi?

When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.

Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.

Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.

Therefore, in comparison to plants, fungi have vacuoles and a cell wall.

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .

Overall, when carbohydrate intake is excessive, lipogenesis ____________


Increase or decrease

Answers

Answer:

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis  decreases.

The process of conversation of stored glycogen in the liver and muscles  to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .

Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose  move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.

Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO

Explanation:

The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.

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.

Answers

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.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?

Answers

Answer:

Oxygen cycles keeps the flow of oxygen at a constant rate.

Explanation:

The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.

Answer:

A.)     The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

Fill in the blank in the following sentence with the appropriate word below.Note the cue in parentheses.Dobla la esquina y sigue caminando (until) la calle SanLuis.A. surB. pasandoC. derechoD. hasta Flight 1 When Robert was a little boy, he wanted nothing more than to see a hawk flying across the sky. Or to see an eagle, an osprey, or a falcon! Robert loved to think about large birds with great yellow talons, soaring across the sky and seeing every corner of the earth that people could not see. 2 But Robert lived in the city, where such birds were never seen. He used to fall asleep at night imagining a hawks wings forming arcs across a great big blue sky, which he pictured as a wide, open field where no legged animals could run but only winged animals could soar. As he drifted into dreams, the birds in his imagination morphed into dragons and pterodactyls and all manner of ancient or other- worldly flying creatures. Robert would wake in the morning smiling at the thought of this big blue field in his dreams. But he spent each day on the subway and walking along crowded sidewalks and looking up between tall buildings where he could catch only a sliver of blue. 3 As he got older, Robert tried to forget about his dreams and focus all his attention on his studies. At school, he took the hardest classes he could and was in advanced placement math and science before long. He decided that if he could not see hawks and eagles and falcons in their natural habitat, he would learn everything he could about how those animals worked. He loved to think about how lessons from birds had led to the first experiments in human flight and the development of airplanes. 4 Robert devoured books about the inventors of the airplanes and the physics that made air travel successful. His devotion to this topic confused his parents, who saw in him a smart and eager child who could study medicine or the law and have a good career. 5 Stop daydreaming about birds! they would say to him. 6 But Robert continued to spend as much time as he could learning about what made flying possible. 7 Sometimes, even as he was older - a college student now, living in a cramped dorm-room with three other boys his age - Robert would drift off to sleep imagining that big open sky filled with hawks and osprey and dragons. He knew it was silly, but he held on to that image. It filled him with hope for something he couldnt quite name. He would ask himself what he was hoping for. 8 Do I want to see a hawk or an eagle or a falcon, or do I hope to someday fly like one of them myself? Robert would say, to no one other than himself. 9 The college Robert attended was also in the city, and he hadnt found a way to travel outside of it yet. He still could only dream about that big blue field above. 10 One day, just before graduation, Robert got a phone call from someone he didnt know. When he answered, the voice on the other end made an unusual announcement. 11 Im looking for someone to test fly a new airplane Im developing, the voice said. Professor Jackson gave me your name. He said he had never had another student as devoted to the art of flying as Robert Smith. Would you be interested in coming in to learn more about my new plane? 12 Robert jotted down the address and date of the interview, and hung up the phone smiling. He couldnt help but close his eyes and picture the big blue field, filled with all manner of flying creatures. Maybe soon he would be among them. 1.
