Los métodos hormonales son eficientes porque: * A: impiden la entrada de los espermatozoides C: Se inhibe (no se desarrolla) la ovulación B: El óvulo jamás se encuentra con el espermatozoide D: Los espermatozoides quedan atrapados y no llegan al óvulo
Answers
Answer: C: Se inhibe (no se desarrolla) la ovulación.
Explanation:
Los métodos anticonceptivos se utilizan prevenir el embarazo no deseado, evitando que el esperma fertilice a un óvulo. Hay distintos tipos, los cuales se clasifican en:
Anticonceptivos hormonales: Contienen hormonas, tales como estrógeno y progesterona, que previenen la ovulación (es decir, la liberación de óvulos de los ovarios). De esta manera, al no haber óvulo disponible, por mas que hayan espermatozoides, no va a ocurrir ninguna fecundación. El método mas conocido es la píldora o pastilla anticonceptiva. Anticonceptivos de barrera: Proveen una barrera física que impide la fecundación al impedir el encuentro entre el óvulo y el espermatozoide. Por ejemplo, el uso de preservativos o condones. En estos métodos, se impide la entrada de los espermatozoides, no se encuentran con el óvulo y la esperma queda atrapada dentro del condón. Anticonceptivos permanentes: Proveen un método permanente como por ejemplo el Dispositivo Intrauterino que se coloca en el tracto uterino con una vida media de meses o años y posee un efecto espermicida que mata a los espermatozoides (por lo que no lograrán encontrar un óvulo). Otro ejemplo es la vasectomía, la cual es una cirugía que corta los conductos deferentes que transportan a los espermatozoides por lo que ya no pueden salir de los testículos para producir la fecundación (quedan atrapados dentro de los testículos, no entran al tracto uterino y no encuentran al óvulo)Tanto los métodos de barrera como los permanentes, no inhiben la ovulación aunque si impiden que el óvulo se encuentre con el espermatozoide. Entonces, los métodos hormonales son los únicos que logran inhibir la ovulación. Las píldoras que poseen las hormonas previamente mencionadas pero fabricadas sintéticamente. Las mismas mimetizan el efecto de las hormonas naturales producidas por el cuerpo, alterando el ciclo menstrual regular y así evitan el embarazo ya que no habrá óvulo disponible para fecundar. Además, también pueden alterarla mucosidad en el cuello del útero para que los espermatozoides no pueden atravesarlo y llegar al óvulo. De todas maneras, el objetivo principal y mas importante de los métodos hormonales es bloquear la ovulación.

B. They move along with the layer of slightly softened rock below them
C. They move by floating on a layer of completely melted rock below them
D. They do not move until the solid rock layer beneath them temporarily melts and moves
Answers
Answer:

Explanation:
the tectonic plates or the crust of the earth sit on molten rock moving across the planet with causes the plates to move causing things like earthquakes and volcanos
Movement of Earth's plate can be due to many reasons and can cause many disasters. They move along with the layer of slightly softened rock below them
What is the 3 causes of this movement?Earth's plates move due to the intense heat in the Earth's core. This causes the movement of soften rock in the mantle layer.
It moves in a convection cell pattern that forms by rising of warm, cooling and then sinking down of material.
The Earth's plates move by floating on a layer of completely melted rock below them.
Thus, the correct option is B.

Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1
Answers
Answer:
None of the above
Explanation:
Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3Answer:
The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.

Answers
Answer:
The density of a white dwarf is 1 x 109 kg/m3.
Explanation:
A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 109 kg/m3. Earth itself has an average density of only 5.4 x 103 kg/m3. That means a white dwarf is 200,000 times as dense.
1 x 10⁹ kg/m³ is the density of white dwarf. It is 200000 times denser than Earth. And it is the second densest object we know after neutron star.

Answers
Complete question:
Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
1) What is the control group?
2) What is the experimental group?
3) What is the independent (manipulated) variable?
4) What is the dependent (responding) variable?
5) What should Tina's conclusion be?
Answer:
Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y. Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.1) What is the control group?
Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.
2) What is the experimental group?
Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.
3) What is the independent (manipulated) variable?
Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.
4) What is the dependent (responding) variable?
Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.
5) What should Tina's conclusion be?
Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.
