During the relative refractory period, _______. During the relative refractory period, _______. another action potential can be generated provided the stimulus is relatively smaller than the original stimulus. another action potential can be generated provided the stimulus is large enough. the flow of potassium is also depolarizing the neuron. a second action potential cannot be generated, no matter how strong the stimulus.

Answers

Answer:  

During the relative refractory period, another action potential can be generated provided the stimulus is large enough.

Explanation:

The relative refractory period is the time after an action potential where the sodium channels are transitioning from inactivated channels to closed ones. In other words, voltage-gated Na+ channels have two gates, an external one and an internal one. During repolarization, the outer gate is blocking the entrance, and the internal one is open. So the channel is inactivated. When the inner gate is closed, the Na+ channel is closed.

During the relative refractory period, a second action potential can happen, but the stimulus has to be large enough to do it since the membrane is hyperpolarized, that is to say, the membrane potential is more negative than the resting action potential. The cell needs more Na+ ions to produce the second action potential.

Answer:

The Answer is C

Explanation:

When scientists breed cows to produce more milk, this has not occured naturally and thus is not natural selection.

Explanation:

The scientists breed cows that give greater amounts of milk than their ancestors is not an example of natural selection. So, option (C) is correct.

A scientist studied a population of birds for 10 years. During that time, the population was never fewer than 30 birds and never more than 50. Her data showed that over half of the birds born did not survive to reproduce, because of competition for food and predation. She noticed that In a single generation, about 90% of the birds that were born lived to reproduce, and the population increased to 90. Which inference(s) about this population might be true

Answers

Answer:

A particular population limiting factor or factors must have been removed

Explanation:

The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.

For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community.

Trastorno alimenticio caracterizado por una gran pérdida de peso, que el propio paciente se provoca y que puede conducir a un estado de inanición.

Answers

Answer: Anorexia nerviosa.

Explanation:

La anorexia nerviosa es un trastorno o desorden alimenticio en donde se produce un rechazo de la comida debido a un temor excesivo a subir de peso, llegando a un estado de inanición serio. Entonces, se produce un deterioro en la salud y una debilidad causada por una ingesta insuficiente de nutrientes causando una desnutrición que altera diversas funciones del organismo. Es mas común en mujeres jóvenes o adolescentes aunque se reportan casos en ambos sexos y a cualquier edad. No debe confundirse con otro trastorno llamado simplemente anorexia, que es un síntoma que se caracteriza por una falta de apetito debido a alguna causa orgánica.

Este trastorno puede ocurrir por diversas causas que vienen acompañadas por una distorsión de la imagen corporal propia, en donde la persona considera que debe perder más peso de lo que se considera saludable y normal para su edad y estatura, llegando a estados raquíticos. También hay muchos casos en donde además de una dieta extrema, se realice ejercicio de manera excesiva o que utilicen otros métodos para bajar de peso como el abuso de laxantes u otros medicamentos.

 Algunos factores de riesgo para el desarrollo de la anorexia nerviosa pueden ser:

Personalidad perfeccionistaImagen propia negativa o baja autoestimaPresiones socialesPadecer algún trastorno de ansiedad

Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.

Answers

Answer:

The correct answer is  a. can be activated by the release of epinephrine.

Explanation:

Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

How does sugar leave the phloem?

Answers

The high turgor pressure drives movement of phloem sap by “bulk flow” from source to sink, where the sugars are rapidly removed from the phloem at the sink. Removal of the sugar increases the Ψs, which causes water to leave the phloem and return to the xylem, decreasing up

Reproduction for dolphins and badgers and people is more complicated because
A. we have to apply for a license before we can reproduce

B. have to find a partner

C. go through the cellular process of MITOSIS to produce sex cells.

Answers

Answer:

B. have to find a partner

Explanation:

When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.
