Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?
Explanation:
if you want to imagine about space
first of all you need to clear your mind
and you need to concentrate your mind on the space and imagine .if you are not getting anything then drink some water and repeat the same process . I hope you will be successful to imagine space ..
best of luck

How is your body temperature held constant despite different weather temperatures
outside?
Answer:
Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.
Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.
at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

Resuelve el problema relacionado con las etapas del ciclo menstrual: "Si el día fértil de la polola de Luciano es el 09 de noviembre y ella tiene un ciclo de 28 días ¿ Cómo puede calcular el primer día de menstruación de su polola en ese mes y el período fértil? En la respuesta debes registrar: Primer día de menstruación, Día de ovulación y período fértil.
Answer: El primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación)
Explanation:
El ciclo menstrual está compuesto por cuatro fases: menstruación, fase folicular, ovulación y fase lútea.
Menstruación: Eliminación del revestimiento engrosado del útero (endometrio) del cuerpo a través de la vagina. El flujo menstrual contiene sangre, células del revestimiento del útero (células endometriales) y moco. La duración media de un periodo es de entre tres días y una semana.Fase folicular: Comienza con la menstruación y termina con la ovulación. La glándula pituitaria libera la hormona estimulante del folículo (FSH), estimulada por parte del hipotálamo. Esta hormona estimula al ovario para que produzca entre cinco y 20 folículos (nódulos o quistes diminutos), que se acumulan en la superficie. Durante la fase folicular, el folículo en desarrollo provoca un aumento del nivel de estrógenos. El hipotálamo, en el cerebro, reconoce este aumento y libera una sustancia química llamada hormona liberadora de gonadotrofina (GnRH). Esta hormona hace que la hipófisis produzca niveles elevados de hormona luteinizante (LH) y FSH. En el plazo de dos días, los altos niveles de LH desencadenan la ovulación. Ovulación: El óvulo es conducido hacia la trompa de Falopio y hacia el útero por medio de ondas de pequeñas proyecciones similares a pelos. La vida del óvulo típico es de sólo unas 24 horas. A menos que se encuentre con un espermatozoide durante este tiempo, morirá. Entonces, la ovulación consiste en la liberación de un óvulo maduro desde la superficie del ovario. Suele producirse en la mitad del ciclo, unas dos semanas antes de que comience la menstruación.Fase lútea: Durante la ovulación, el óvulo se desprende de su folículo, pero el folículo roto permanece en la superficie del ovario. Durante las dos semanas siguientes, aproximadamente, el folículo se transforma en una estructura conocida como cuerpo lúteo. Esta estructura secreta progesterona y estrógeno. Esta combinación de hormonas mantiene el revestimiento del útero engrosado, a la espera de que se adhiera un óvulo fecundado (implante). Si el óvulo fecundado se implanta en el revestimiento del útero, éste produce las hormonas necesarias para mantener el cuerpo lúteo. Esto incluye la gonadotrofina coriónica humana (HCG), la hormona que se detecta en un análisis de orina para detectar un embarazo. El cuerpo lúteo sigue produciendo los niveles elevados de progesterona necesarios para mantener el grosor del revestimiento del útero. Si no se produce el embarazo, el cuerpo lúteo se marchita y muere, normalmente alrededor del día 22 de un ciclo de 28 días. El descenso de los niveles de progesterona hace que el revestimiento del útero se desprenda (menstruación)La duración media del ciclo menstrual es de 28-29 días, pero puede variar entre las mujeres y de un ciclo a otro. La duración del ciclo menstrual se calcula desde el primer día de la menstruación hasta el día anterior al inicio de la siguiente.
Si consideramos que el primer día fértil es el 9 de noviembre y el ciclo es de 28 días, el primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación) Esto es porque la menstruación ocurre aproximadamente 14 días luego de la ovulación si el ciclo es de 28 días. Los días más fértiles son aproximadamente desde 3 días antes de la ovulación. Aunque en algunos casos, la fertilidad puede durar hasta dos días después de la ovulación.

Choose ALL that apply for mangroves.
Mangroves have bladders in their leaves to dilute the seawater.
Aerial roots act as support to hold their tops above water.
Mangroves han leaves that contain glands, which expel salty water.
Holes in the central stem take in air for the roots of the mangrove.
Answer:
Aerial roots act as support to hold their tops above water.
Mangroves has leaves that contain glands, which expel salty water.
Explanation:
A mangrove is a shrub that grows in coastal saline or brackish water due to their salt tolerance abilities. Aerial roots act as support to hold the plant in water as well as provide oxygen to the plants. These aerial roots are present outside the water so that to provide oxygen to the plants directly absorb from the atmosphere. Mangroves leaves contain glands, which removes salty water from the body so due to these glands, mangrove is able to grow in saline water.

Explanation:
Cuando pasa una molécula de una zona de menor concentración de sustancias a una zona de mayor concentración, el transporte implicado es
Answer:
Transporte activo.
Explicación:
El transporte activo ocurre cuando una molécula se mueve de un área de menor concentración de sustancias a un área de mayor concentración. Los transportes activos utilizaron energía en forma de ATP para mover moléculas en contra del gradiente de concentración. Es lo opuesto al transporte pasivo en el que no se requiere energía para mover moléculas de una región a otra. La principal razón de que ocurra el transporte activo es que mueve moléculas en contra del flujo de difusión. En difusión, la molécula se mueve de un área de mayor concentración a un área de menor concentración.
